2025 TPMS

I will ask, when I get the installation done in a few weeks (see my post #21 in this thread, for anyone just jumping into this thread), whether the TFT firmware can be updated, in general, when the change is made to add, unlock, or whatever needs to be done to the firmware in order to show the tire pressures, tire-pressure warnings, and so forth.

I am referring to recent changes such as moving the tach info to another screen while ditching the "Urban" screen, that sort of thing. See this thread, for example, for further info on what I'm talking about: https://www.bmw-scooters.com/threads/urban-feature-missing-on-c400gt.3486/

not trying to be a smartass here BUT imo asking these techs about ANYTHING related to this entire process OR anything related to programming is a JOKE most likely as they probably NEVER done ANY of this prior, now unless u get one who is curios or would like to expand their professional knowledge(which i doubt) they would go in there and see ALL the options/configurations/movements/etc that are/are not possible while hooked up???? again, this takes someone with fwd big pic thinking, so guessing this will not happen on your visit or at best you will get the absolute MIN info possible, but hey, it does not hurt to try..... 🤠

Oh, I hear ya.

I'll make my request, in hopes that I get a tech doing this who has a thirst for knowledge, takes pride in his work and job skills, etc. Maybe I'll get lucky.

Just a little rambling on my part after reading all these posts.
If my calculations are correct from Rugerbears post this is likely to cost $682.00 och. It was $260.00 on my indian Challenger. ($129.00 ea for the sensors and they auto detected.) My recolection was that there was no indication of TPMS on any screen before the sensors were installed and it automatically came up after the sensors were installed.) I thought that was expensive. Purchasing 4 sensors for less than $100 on Amazon for my 2010 mini cooper snow tires and they auto detected. (Had to drive around 15 minutes.)
My 2023 Chevy Bolt does not auto detect when I change from street to snow tires and back. The guy at Discout Tire who changes them has to walk around to each tire with a unit and set them manually to detect. It takes him all of 2 minutes to do all 4 tires. (I watched him do it.)
 
August 13, 2025: APPROVED BY MAX BMW FOR RETROFIT

I spent about an hour and a half at MAX BMW in Troy, NY, late this afternoon, reading a book, while after a bit my scooter was wheeled into the shop area and put on a lift (I peeked back there, but didn't attempt to hang out there).

The bottom line is that:

1) My '23 C 400 GT passed muster, was designated fit for a retrofit, after being hooked up to some official BMW device.

2) I am now on their shop schedule for the first week in September.

My wife and I will be OOO that week, so I got permission to drop off the bike the week before. Given our and MAX's schedules, I expect to pick up the bike on Sept. 9 (unless it's raining buckets), so look for my next report on this topic a day or two after that.

COST:

The service writer pointed out that I'd need two of the RDC sensors @ $110 each (see that parts page in posts 12 and 15, above), some miscellaneous small hardware items, and about an hour and a half of labor. I'm guessing, with tax, about $500.

(Or, put another way, about $400 more than adding a pair of high-quality FOBO external sensors --which you can't do anyway on the front wheel -- and getting the convenience of having the info displayed on the TFT.)

SCHEDULE:

The appointment of about three weeks down the road is actually sooner than I expected. The service writer had first asked me whether I wanted to wait until I needed new tires, in order to save on that labor. I told him, "---k, no. This TPMS quest of mine is like Ahab going after Moby-Dick, so let's get it on!"

SUITABILITY FOR OTHER C 400 BIKES?:

I met briefly with the tech that did this check, on my way out the door. I tried to get a clear answer, regarding if this retrofit compatibility applies to certain years, etc., but I couldn't determine that. I think he's not ready to make blanket statements, but after checking the 1s and 0s inside the bike he was certain that my particular bike met the criteria. Sorry that this isn't very useful information.

Last, here's my receipt for today's work:

UPDATE, AUG. 28, 2025: I NEED A PLAN B, OR MAYBE A PLAN C, OR MAYBE ...

==> For those waiting with bated breath for what I said would be my upcoming report in a couple of weeks: you can breathe normally now. It's not going to happen, at least not at that time.


I thought I'd reply to my own post, earlier in this thread, to save anyone who's following this the trouble of backing up a page.


1) I phoned the Service Dept. at MAX BMW in Troy, NY, this morning, to make sure it was still okay for me to drop off the bike this afternoon, for my RDC install next week. The service writer had asked me to do this, and told me, yep, this afternoon would be fine.

However, early in the afternoon I got a call from him. The service writer now said to me:

A) After (re?)checking with Gregg Templeton, the Parts Manager, presumably to make sure that everything was in order, he was told by Gregg that I would also need a control unit.

B) That control unit would take four weeks to arrive from Germany, so my appointment would need to be rescheduled.

C) That control unit -- all by itself -- would cost me $509, and MAX BMW would need a deposit to order it.

That would bring the work close to $800 for parts: $509 + ($120 x 2) + odds and ends. And with labor and tax, the total would be well over $1,000.

==> I told the service writer that I believe Gregg is wrong, but that I had no way to prove that. And I told him to forget the whole thing, no need to reschedule the work.


2) Gregg is a pretty knowledgeable parts guy, been at MAX for decades now. But everyone there knows that they've never done this before -- tried to retrofit a TPMS for any year of the C 400 GT -- so in this case, much as I respect his experience, it counts for nothing.

This sounds just like the WhatsApp exchange I had with Phad in Thailand.

In Oct. 2024, I noted that Phad stated I would need a controller, as I reported in post 2 in a different thread: https://www.bmw-scooters.com/threads/tpms-programming.3294/post-27730

However, about a week later, after further exchanges, and after I gave him my VIN, Phad corrected himself, as I reported in post 5 in that thread: https://www.bmw-scooters.com/threads/tpms-programming.3294/post-27798

His correction was this statement: "Also no need control unit, no wiring."

I believe that Gregg (the local Parts Manager) has fallen into the same trap (even though those folks know my VIN, because I bought the bike there, and because I've included it in most of my emails to them).

I believe that the tech I spoke with a few weeks ago did NOT fall into that trap.

==> I will pay another in-person visit to the dealership in a couple of weeks, and try to explain all this to Gregg, ask him to meet with the tech who had not said a controller was necessary, and see whether I can get the folks there to reach a dealership-wide consensus.


3) And I'll attempt to touch base with Phad again.

==> I will send him a message, asking if he wouldn't mind telling me what reference or document he used, when he determined that my particular C 500 GT, based on its VIN, did not need a control unit.

I'm guessing that he knows how to look up C 400 requirements for RDC retrofitting better than the local folks.


4) ==> I'm going to send an email to BMW Motorrad NA, asking for clarification.

I imagine that some of you will scoff at this, and that the likelihood that I'll learn anything useful is slim. However, scoffing is easy but not very productive, and, on the other hand, I like to be thorough, you never know, nothing ventured nothing gained, etc., and this only costs a few minutes of my time.


5) ==> If anyone else actually has such a retrofit on a C 400 (GT or X) done by an actual BMW dealer, I'd certainly like to hear about it, learn where it was done, what parts were involved, and so forth.

As I've said before, I don't care what a dealer in TX or a parts guy in NY or anyone else in Beemerdom says -- ya know, money talks, bullshit walks -- Phad, the indie tech in Thailand, is the only person that I'm aware of that's done this. If it really costs an actual owner over USD 1000, I can see why.

I would appreciate it if some of you owners with '24 or '25 models would step up here, so at least I can show the folks at my local dealership that it CAN be done without a controller, at least on some of the C 400s. C'mon, life is short, live a little -- I mean we ARE on a BMW forum here.
 
fwiw, my experience with bmw usa 2 wheel div/dept is; they have NO "expert"/spec tech person you can speak with(or if there is one they will not connect you) and you are forced to explain your issue to a person who has NO CLUE and will try to look up what is is you are calling about and if they generate an answer(whether it correct or not cause they have no clue) this is what they will read off to you... u get the deer in the headlights look over the phone!!! it is very frustrating and sad that it has come to this because off their personnel reorganization and the rule of no longer being able to talk directly with the "smart" person.... i refuse to call anymore because just a cpl months ago when i had questions(abt this topic) i was on hold for 45min before hanging up!!! it seems it is just the "norm" today with all the outsourcing and plain lack of cust svc!!!
anyhoo good luck with your quest and imo this project is getting tooooooo pricey for what it is(if module req) but hey it's not my $

I get it 100%. If I want something, it's available, and I can afford it, I will usually go for it! All you can do is pay too much. Otherwise you keep regreting not having it. I also agree that there are likely no experts in the USA on these scooters because they don't sell enough of them here.
The electronics are probably similar to a lot of BMW Motorcycles so at least in this respect the mechanics know how to work with BMW and how to get the information from the computer that they need to determine certain things. I'm happy for you that you are finally going to satisfy this quest! You have put way more than $500 in time and research into this project. So to be able to finally sit back and let someone else do it has got to be a great feeling.

UPDATE, SEPT. 9, 2025: CHECKED AGAIN WITH PHAD, WROTE TO GERMANY, VISITED DEALERSHIP, LONG TALK WITH PARTS MANAGER, SENSORS ORDERED

Executive summary of the previously most recent background (see post #48, above): the long-time Parts Manager ("PM") at my local dealership (Max BMW, Troy, NY) informed the service writer, just before I was to drop off the bike, that I needed a $509 control unit, in addition to the sensors. I temporarily abandoned ship.

New Info:

Since then:

1) I emailed the mothership in Germany. In part, their reply said this:

We have forwarded your e-mail to the relevant subsidiary, BMW Motorrad USA, for further assessment. You will be contacted as soon as possible.

BMW USA got back to me, and in part said this:

While I wish I could provide a direct solution, our team isn't equipped to offer technical advice or services for your Motorrad. Our authorized BMW Motorrad dealers have specially trained service teams who are best suited to diagnose and address such issues, thanks to their extensive training on BMW motorcycles.

I highly recommend continuing to work with the service team at your preferred authorized BMW Motorrad dealer for further guidance. If you have not already done so, I recommend speaking directly with the Service Manager. They are in the best position to provide the most accurate information and assist you in addressing your concerns. You can find a complete list of authorized dealers on our website at https://www.bmwmotorcycles.com/dealer.


That was pretty much as everyone expected, right?

2) I recontacted Phad in Thailand. Here are some screenshots of that WhatsApp exchange:

Phad 10.webp

Phad 20.webp

Phad 30.webp

Phad 40 2.webp

So Phad ignored (or didn't understand) my request for info on his method -- what document, what manual, or parts fiche, etc. -- of determining what C 400s need a control unit, and what C 400s do not. That is, I didn't get an answer, regarding how he used the last seven digits on my VIN.

On the other hand, he reiterated what he had last told me: I don't need the controller.

3) Having returned from vacation over the weekend, I visited the dealership today.

I had a long talk with the PM, showed him the exchange with Phad, and told him that as far as I know Phad is the only person in the world who has done this upgrade to a C 400 (unless he faked the videos on his YouTube channel).

The PM then requested that a lead tech -- the person who almost a month ago (see post #21 here) had stated that I was good to go, regarding the upgrade -- join us. When the tech had a free minute, the three of us discussed this some more.

The PM stated that this may be a case of BMW's making a new-ish part available -- the RDC sensors for the C 400 -- and not letting the dealers know about it in any bulletin, that sort of thing. The PM stated that he had never ordered that part. I gather that he was thinking that other, more common, RDC sensors would have been used.

In any event, he agreed that it might be feasible that these particular sensors might be automatically picked up by my particular bike, and so ordered them ... because apparently being uncommon, unlike what I was told weeks ago, they do not stock this particular part. He ordered the part number that Phad listed (see above), which is also the part number that I encountered when looking at the parts fiche at Max BMW's very own web pages for my C 400 GT. Here's the order:

2025-09-09.webp

The PM also stated that it might be two to four weeks to get the sensors, and that he'd call me when a shipping date was known, and I could then schedule the service. Because these are not stocked by them, I had to pay up front for the sensors, unlike for my prior, aborted, appointment.

He also said that it would be less than two hours' labor, if it turns out that no or negligible programming is required. (He asked me if I needed new tires, so I could save on the dismounting/remounting labor, but it turns out that I'm not even close, as I have about 1,800 miles on the City Grip 2 that I had them install over last winter).

I'm not sure what changed his mind, e.g., the further parts research he did today, or my exchange with Phad, my physically showing up to debate the issue with him, or something else. And I don't know what part he thought would have been installed, i.e., what particular RDC sensor variant, when I almost had this work done, when I first scheduled for the installation work last week.

So, that's where things stand: as of today, I've now invested $294 in this project, and with labor and tax I'll probably spend a similar amount after the parts arrive and I get a new schedule for shop time.

I am hopeful that this all turns out well and there is little or no programing required. If that is the case someone with a 2023 scooter could potentually get the sensors and have them installed during a tire change for a little over $300.00 from the dealer.
 
UPDATE, OCT. 1, 2025: SENSORS INSTALLED, EVERYTHING WORKING, NO CONTROL UNIT

Okay, the RDC sensors arrived from Germany a couple of weeks ago, and when they did Max BMW contacted me, to schedule the installation.

That installation was this afternoon, and it went fine (other than costing me a good chunk o' change, of course, for something that should have been included in the Premium Package, or perhaps a new Extra Special Premium Package).

To put this in one post, here's a reposting of my prepaid sensor-order receipt, followed by today's receipt:

Max BMW receipt 2025-09-09 RDC sensor order, expurgated.webp

Max BMW receipt 2025-10-01 RDC sensor install expurgated 2.webp

And when I got home I recorded a 48-second video, so y'all can see what it looks like, in terms of the TFT display:


And if you don't want to click on Watch on YouTube and then click on my full description, here's the text I added underneath that video on YouTube:

=======================================================================
=======================================================================
=======================================================================

DISCLAIMER: To forestall comments about this, note that I run my tires with a much lower pressure, typically 33 PSI front and 36 PSI rear. This video was made right after arriving home after the installation, and those pressures were what the dealership inflated the tires to. Before my next ride, I will lower the pressures to my usual values.

Today, Oct. 1, 2025, I had the internal RDC (BMW's term for TPMS) sensors installed inside the rims of my 2023 C 400 GT scooter, and the bike's TFT display software updated accordingly, by my local BMW dealership (MAX BMW's Troy, NY, location; see https://www.maxbmw.com/ ). This video shows the result of that work.

Based on my research and assorted posts on the BMW Scooters forum (https://www.bmw-scooters.com/pages/Ho..., I may be the first C 400 owner in the USA to have this work done. For one thing, relative to the purchase price of the bike, it's an expensive upgrade. For another, there is much confusion among dealer service departments regarding whether this change can be done at all, and, if it can, what parts are required.

In terms of cost, parts were about USD 294 and labor about USD 363. I think about half of the labor cost could be saved if this upgrade were performed when new tires are also being installed.

(I admit that I'm somewhat obsessed by all of this. I could've gotten away a lot cheaper by using external sensors -- I've been very pleased with quality units from FOBO, for instance -- were it not for BMW's jackass placement of the Schrader valves sideways, in the spoke-like portion of the wheels. I had a FOBO sensor in the rear wheel, but with two brake calipers up front an external sensor on that wheel would smack into one of the calipers.)

In terms of parts, much of the confusion involves whether a USD 500 "control unit" is required. According to independent BMW specialist Phad Motorrad in Thailand ( / @phadmotorrad ), that unit was NOT needed for my bike, based on my VIN. Note that the build date of my '23 C 400 GT was July 18, 2023 (according to https://www.mdecoder.com/ and https://bimmer.work/ ).

Regarding my queries, asking for clarification on build dates and parts requirements for this upgrade, neither BMW Motorrad in Germany nor in North America was any help; the former referred me to the latter, and the latter referred me to individual dealerships. Even within my large, well-established, long-time local dealership, there was uncertainty, confusion, and differences of opinion within the parts and service departments.

The bottom line is that you're pretty much on your own if you're a C 400 owner who wants to pay for this upgrade. My particular bike required two 36 31 7 106 019 RDC sensors (c. USD 114 each) and two 36 31 7 106 018 Torx screws (c. USD 22 each). The sensors had to be imported from Germany, which took a couple of weeks.

Now if Veridian (https://veridiancruise.com/ ), a Canadian company that makes cruise controls for throttle-by-wire bikes, ever gets around to fabricating one for the C 400 (see https://veridiancruise.com/future-bikes/ ), my two major complaints regarding the C 400 will have been ameliorated. (If you're a C 400 owner, I'd appreciate it if you would contact Veridian -- [email protected] -- and ask them to add your name to those requesting a C 400 cruise.)

If BMW hopes to compete in Europe and Asia with the likes of the Zontes and Voge in the 350cc - 370cc range, they have to up their game. Those companies make similar scooters, some of which have factory TPMS, and all of which are thousands of dollars less expensive. But I digress ...

Last, if any owner of a different late-model BMW could explain to me what the values of the two sides of the TIRE PRESSURE display screen represent, I'd be grateful for a comment or two on the matter. That is, naturally no manual was provided with this change, and I'm not aware of any documentation on this, so I'm left to wonder whether those are minimum and maximum observed pressures, pressures at startup (as opposed to the increased pressures when actually riding), and so on.

One last observation: the tires seem to have to be rotated for a bit -- I've read that you have to get up to 19mph -- in order to replace dashed lines with an actual reading. This is somewhat disappointing, as it precludes a pre-ride pressure check. This is NOT the case with some external sensors from FOBO and others, but is similar to the way my fairly expensive sole auto works (the car must initially achieve 15mph). Ah, well.

Thanks! I can never get a Green OK on the oil check just ---
I can get the green OK on the oil light in place of the dotted line. I have to have the bike parked in my garage (on level ground) on the back stand, right after a ride. I let it set and idle a few minutes and walla. The OK appears if the oil level is good. I thought it would be something I could see all the time while riding but it's not.
 
I came into this thread because it was labeled 2025 TPMS. Turns out, all of the discussion was about retrofitting earlier models. But, in case anyone is interested, the Rider's Manual for a 2025 discusses TPMS (as an OA) and an alarm system (as an OE). Still not an ordering option, but I had both of these options installed by the dealer on my 2025 at the 600 mile service. No issues and everything is working great.

1) First of all, my apologies for the thread drift that you described. It's largely my posts that took up a lot of that non-'25 space here.

In my defense, I had to put my saga somewhere, as there are some folks with pre-'25 C 400s that are very interested in the topic. I probably should've put my story in one of the other existing TPMS threads. But, as you saw, the thread just spiraled away. Sorry.

2) Pretty strange, don't you think -- if I understand you correctly -- that a prospective buyer just can't order a hot-off-the-presses brand new C 400 with those options from the factory.

You have any thoughts on that strange state of affairs.

3) If you don't mind, could you detail what it cost you (parts and labor) for each of those add-ons, the alarm and TPMS?

If you don't feel like sharing that info, so be it, but I think new or prospective owners of a '25 would be very interested in learning what they were. (I've already detailed my expenses for that reason, for owners of prior model years.)

In any event, congrats on your new scoot, and for bringing it more up to snuff. (Now if BMW or Veridian would only start offering cruise control, we'd have actual Grand Tourers.)
 
No apologies necessary. Yes, strange to me as well that BMW doesn't offer these as part of a package or at least as listed ordering options. I said as much to Motorrad on a survey that they sent me after purchase. To me, those were two items missing from the Premium Package that should be included there. As far as cost goes, you won't be surprised that it wasn't cheap! Will vary somewhat by dealer I expect, but I paid ~$700 total for each install.

Thanks for the additional info, and your thoughts.
