2025 TPMS

MeSeaHunt said:
is this a standard included feature for the model OR does it have to be added to the software at the dealer? thanks
Click to expand...
As far as I know, the answer is neither.

1) On the official product page, https://www.bmwmotorcycles.com/en/models/urban_mobility/c400gt/, I don't see any mention of TPMS (nor was it mentioned on that page in years past, for earlier models.

And I haven't read anywhere about a change in this, i.e., I haven't seen any mention of BMW's including TPMS in the '25 model.

2) Take a few minutes and read through these two threads: https://www.bmw-scooters.com/threads/tpms-programming.3294/ and https://www.bmw-scooters.com/threads/carpuride-and-power.3523/.

The executive summary is this:

A) The wheels seem prepped to accept internal TPMS sensors.

B) The TFT firmware, with a suitable update or hack, seems capable of displaying TPMS information.

C) No one that I'm aware of, with the exception of independent tech Phad, in Thailand, has actually done that work, i.e., has put A and B together.

D) Phad has stated to me, in one of our WhatsApp conversations, that the recent C 400 model years -- I gather from at least '23 onward -- do not need any additional hardware, such as receiver box of some sort, to make this happen.

E) My dealership, Max, was not interested, when I tried to get them interested in this hack. Further, all my receipts from Max have this boiler-plate caveat on them that states (I'm paraphrasing): "You mess with the firmware, you void the warranty." That's probably not legally enforceable, but that's what it says.

3) As far as external TPMS sensors go, with no interaction with the bike's TFT or anything else:

F) I had a FOBO (an excellent, high-quality, company, IMO) on the rear wheel of my '22, and moved it over to the rear wheel of my '23 when I got that.

G) No one that I'm aware of, except forum member @byee, has put an external TPMS sensor on the front wheel of a C 400. From my and his research -- I shipped @byee both BMW and aftermarket Schrader valves -- I can tell you that the clearance between a sensor and one of the brake calipers on the front wheel is either non-existent or very tiny (too tiny for my liking, and possibly dependent on which brand and how worn the front brake pads are).

4) The lack of factory (i.e., internal) TPMS on the C 400 models tends to infuriate me:

H) BMW has factory TPMS on almost all of its models.

I) That jackass sideways Schrader valve placement is just BMW's being weird, because they can. No other manufacturer does that. And I'd drill a hole in the front rim, except that it has a V-shape, and a new valve might not seal well.

J) The lack of TPMS and cruise control -- the bike has had throttle-by-wire for a couple of years now, and so how hard could it be -- are my two biggest gripes with the bike.

That answer your question?

You read or hear somewhere that TPMS is a feature, optional or otherwise, for the '25 C 400 model?
 
While at the dealership Saturday they asked if I would like them to do the tpms upgrade on the 24 model, which made me wonder if it was one of the 25 upgrades they did with all the others?
 
The GM(brien) is the person who told me that the 2024 was able for a tpms upgrade per the info he was looking at on the computer in the bmw system? So if you call and speak with the svc mgr tell him to go and ask/confirm with the boss!! Good luck 🤠

REPORT: CALL WITH BRIEN MEHLER, RE TPMS:

This is the email I sent to Brien Mehler (the GM at European Cycle Sports, Plano, TX -- see https://www.europeancyclesports.com/learn-more-about-our--xstaff) on July 20 (the day @MeSeaHunt wrote his post #7, above):

TPMS Modification for 2023 C 400 GT

Mr. Mehler,

I own a 2023 C 400 GT, but live in New York state, a little too far for me to have service done at your shop.

I recently read on a BMW scooter forum that your team offers to add internal TPMS sensors to the C 400 GT, along with making the necessary changes to the firmware on the bike, such that the relevant information is displayed on the bike's TFT.

I had researched this issue myself over the past winter, and it certainly looked like such a change is an option on these scooters.

However -- and this is the reason I'm writing -- the service manager at my local BMW dealership (MAX BMW, at their shop in Troy, NY) didn't seem aware that this was possible when I had some service performed there last fall. Or possibly I wasn't clear enough in stating what I wanted.

I will bring this issue up again with the service department at MAX's in a few days. If I still get a blank stare, I wonder if you could:

1) Double-check that adding TPMS to a late-model C 400 GT is an option approved by BMW Motorrad.

2) And assuming you're correct, would you mind if I ask someone at MAX's to contact you (via phone or email, whatever you prefer) about this option?

Thank you for your time.

Regards,
________________________________________________________________________________________________________


Not getting any response, I phoned him today.

He apparently didn't get, or didn't read, that email. He told me that he was certain that internal TPMS as an "accessory" (his word) could be added to the C 400 GT (as @MeSeaHunt reported), along with corresponding firmware changes, both done by your friendly neighborhood BMW dealer. I mentioned that I had a '23 C 400 GT, and he said he wasn't sure of that, but that he was sure of the '24s, and that whether this could be accomplished was "based on VIN."

I told him that I would touch base (more clearly than in the past) with my local dealer. He offered to check my VIN if I had no luck with them (which was nice).

I will, in fact, swing by my local place on one of my next rides, perhaps on Friday.

Next, I rechecked the parts fiche from MAX BMW. You'll note at https://shop.maxbmw.com/fiche/partsfiche.aspx that there are entries for "C400GT 18" and "C400GT 21." Clicking on the latter takes you to https://shop.maxbmw.com/fiche/DiagramsMain.aspx?vid=62062&rnd=10232024 , and the heading on that page is:

C400GT 21 (K08)
Production: 04/20-05/24 USA

If you scroll all the way down the diagrams, you come to this:

CleanShot 2025-08-06 at 14.15.34@2x.webp

Note that bit about "NOT FOR VEHICLES WITH KEYLESS RIDE (CODE: X193A)." Correct me if I'm wrong, but I assume that means a bike with a fob, which is what my former '22 C 400 GT had and which my current '23 has.

In that next bit, "RDC" is BMW-speak for TPMS.

I don't know if those two "AND" really mean "OR" in terms of logic. If they really mean AND then the note is saying, "If you already have TPMS installed, then don't get this."

On the other hand, if they really mean OR, then the note is saying, "If you have a fob, or if you have a recent ('22 - '24? '23 - '24?) C 400 GT then you can't use this part."

Bottom line: I still don't know what's going on, and I'm not sure I can go by what Mr. Mehler thinks he knows. The Service Manager at MAX in Troy, NY, that I was used to dealing with is no longer listed in the Staff Directory there, so maybe I'll get a different answer when I attempt to clarify the issue.

No, here's a better bottom line: unless and until I read of someone's actually having this change made -- internal TPMS added, and corresponding TFT-related changes -- I still don't believe it, but I'll try to keep an open mind. And by "someone" I mean an owner in the USA, working through a BMW dealership in the USA (as opposed to, say, independent tech Phad in Thailand).

Once again, I'll report back with any new findings.

This is what I expected from BMW Motorrad… confusion. No one can provide a definitive yes or no answer. Each person you ask gives you a different answer.

I bought the BMW ConnectedRide cradle when it first released from Europe. My local BMW Canada dealership indicated it should work out of box. BMW USA indicated the GPS option had to be enabled.

I opened a support ticket with BMW Connected for support. I spent 3 weeks explaining and re-explaining the issue to them.

Eventually just gave up & shipped the ConnectedRide cradle back to Europe. This fiasco costed me $$$$$ for shipping to and from as well as tariffs paid.

I expected BMW to have a knowledge base library of articles for these types of questions. For example, can TPMS be added to the C400GT? Is the ConnectedRide cradle compatible with the C400GT? If yes, this is what’s required. If no, this is why.

My rant for the day!🤪

Good luck!

Thanks for the wish, and sorry about your former hassle.

You been reading the thread about derated power on the CE-04: https://www.bmw-scooters.com/threads/de-rated-power-question.3353/ ? Sounds like the same sort of bullshit you encountered with the ConnectedRide cradle, i.e., no one can get a straight answer, especially from the mothership in Germany. And that's a much more serious issue, because it involves the ultimate power of the engine.

In any case, two days ago (08/06/2025) -- not really believing what I was told by the General Manager at European Cycle Sports, Plano, Texas -- I sent this email to the Service Manager of my local BMW bike dealership, one of the four-locations of multi-state MAX BMW:

________________________________________________________________________________________________________

Question on Retrofitting RDC (TPMS) to 2023 C 400 GT

Tony,

Hi, 2023 C 400 GT owner here, in Niskayuna.

This issue of adding RDC to a C 400 GT started with a post on a BMW scooter forum, by a prospective purchaser in Texas.

But of course you can't believe everything you read on the internet, so today I phoned the person this prospective owner talked to: Brien Mehler, the General Manager of European Cycle Sports, in Plano, TX (see https://www.europeancyclesports.com/learn-more-about-our--xstaff).

According to Mr. Mehler, the 2024 -- and possibly my 2023 and other years -- C 400 GT scooters can be retrofitted by BMW dealers with BMW's RDC internal wheel sensors on the hardware side, and corresponding changes made to the TFT's firmware on the software side.

So I had a look at MAX's parts fiche today.

At https://shop.maxbmw.com/fiche/partsfiche.aspx there are entries for "C400GT 18" and "C400GT 21" so I clicked on that latter one.

That takes you to https://shop.maxbmw.com/fiche/DiagramsMain.aspx?vid=62062&rnd=10232024, which is titled C400GT 21 (K08)
Production: 04/20-05/24 USA.

If you scroll all the way down, you come to diagram 77_1568, RETROFIT TIRE PRESSURE MONITOR. This is a screen grab of that page:

BMW Diagram 77_1568, RETROFIT TIRE PRESSURE MONITOR.webp

I don't claim to understand the text in that diagram:

Notes:
NOT FOR VEHICLES WITH
KEYLESS RIDE (CODE: X193A)
AND
RDC (CODE: X530A)
AND VEHICLES PRODUCED
FROM 03/01/2022

I find the wording confusing, especially considering that both my former '22 C 400 GT and my current '23 C 400 GT came with fobs, and presumably so does the '24 (and now the '25).

Here's my question for you: can you tell me whether you folks can retrofit my '23 C 400 GT with those RDC sensors and have the TFT programmed to reflect that? If it matters, my VIN is W...

Thank you for any help with this, and for your time.

Regards,

________________________________________________________________________________________________________


If I don't hear back from him in a few days, I'll ride over there, and ask him why he didn't get back to me.

And if he says, "Oh, sorry I didn't get back to you, and of course we can do that," then I'll say, "Okay, schedule me for the work, and I realize that I'll have to pay for the parts and labor, and, yep, I realize that the labor will include your removal and remounting of my fairly new tires."

I'll keep everyone posted.
 
I had my break in service done today. It is on a 2024 C400GT. I inquired about the TPMS. Service manager said I did have the module already. Just needed to install the RDC Sensors and I think they activate the system. Total parts for both would be about $260. Of course labor was $330. I may have it done whenever I need new tires so labor won’t be so high.
 
So what are you going to say if he just didn’t get back with you???

I have learned a lesson here AGAIN not just on this issue but ALL that has come up with a bmw machine which is; they have gotten like every other company in that customer service has NO priority for them post sale!!! It’s almost impossible to even be able to speak to anyone in customer support, and if you do it’s because you waited on hold forever…. BMW Motorad USA has become a JOKE!!!

The other thing I have learned is that the USA scooter market is currently the worst in the world, manfs are not putting $ into it and they imo could care less if it moves forward in the states, as witnessed by the model selection differences, and when speaking to reps at a dealer or show they say as well this market is not $ generating…

If he just didn't get back to me, I will show him a copy of my email -- to refresh his memory -- and ask him to consider the situation right now.

so when you go in there and you think this person has some sort of intelligence and knowledge of this, inquire if this MOD can or cannot be done up to the current machine??? wish ya luck ;)
 
POSSIBLE PROGRESS:

If you look at post #15 here, you can read the email that I sent to the service manager of my local dealership, MAX BMW's Troy, NY, location.

To be fair to everyone, I sent that last Wednesday evening. So, since the dealership is closed on Sundays and Mondays, that gave them two, or possibly three (I don't know whether the techs work on Saturdays), days to digest that.

In any case, near the start of a ride today, I swung by the dealership, and asked to speak with the Service Manager. I first pointed out to him that I sent him an email last week, about adding TPMS to my scooter. He remembered it, and said that he had passed it along to one of the senior techs.

So we chatted for a bit, and I took a seat in the waiting room (I had been in the large back-room service area, where the actual work is done). He told me that when that tech had a free minute, he get a progress report.

Maybe 10 minutes later, the Service Manager came out, found me, and gave me this report:

1) He said that the tech "thinks so," regarding the possibility that my '23 C 400 GT is capable of accepting the TPMS retrofit.

2) He also said that the tech said that it depends on how my bike is "configured."

3) Last, the Service Manager said that they have to "hook up" my bike (presumably to one of their official BMW firmware readers, or something like that).

I said, okay, let's do this, I'm ready, I'll wait. Not so fast, of course. The SM said, "How about tomorrow at 4pm?" I said, fine.

WARNING TO READERS: this is not to have any real work done, merely to have the bike examined electronically. If the bike passes muster, I suspect that it'll be weeks before they have an open slot for actual work -- programming, removing the tires, etc. -- and they may not even have the internal RDC sensors in stock (although I bet they do).

And here's another note: regarding that "configured" bit (bullet 2, above), I ==> SUSPECT <== that they're trying to determine whether my particular C 400 is past the point of requiring an additional hardware device (that is, in addition to the sensors themselves). If anyone wants background on what I'm talking about, read my post from last October: https://www.bmw-scooters.com/threads/tpms-programming.3294/#post-27798 . In that, the indie BMW tech in Thailand, Phad Motorrad, finally asserted that -- based on my VIN -- I don't need a "control unit" (which he had earlier stated need to be added to the scoot, and wired up in some way).

At least Phad has experience in all this, as opposed to, I think, any dealer in the USA. If you poke around his YouTube channel (https://www.youtube.com/@phadmotorrad/videos ) you can see that he's actually done this, i.e., added BMW's internal sensors to a C 400, and made the appropriate TFT changes.

Anyway, that's my ==> GUESS <==, i.e., that they're attempting to make sure that all I need are those RDC sensors. A corollary to that is another ==> GUESS <== that if they find that additional hardware would be required -- that "control unit" -- they'll say that my bike can't be retrofitted, that that "accessory" parts fiche diagram doesn't apply to my bike.

I will, of course, report back, hopefully tomorrow evening.
