Nope. The last time I checked the display was not presenting any data on the oil.
Idle rpm
- Thread starter dimatrixxx
- Start date
I went to the dealer yesterday to get the idle adjusted. I guess there are a few things. First, there were software updates to the ECU and the display. The tech said they do not inform them of what the updates address, just that they must be installed. My software version on the display is now 023-011-090 (learned earlier in this thread that this is unrelated to the ECU software). He had to manually set the RPMs and it is running right at 1500 now. I hope that I come across as someone who can evaluate if a bike is running/riding better after an upgrade or update. The bike is running noticeably smoother at speed and at idle after whatever they did yesterday...meaningfully better.
I mentioned the vibration at certain speeds. The tech rode it, identified it, and was not concerned with it. Nonetheless, he thoroughly inspected the transmission and said everything is spot on. He also said he observed that same vibration on several other GTs he has ridden. I trust this guy, by the way. He said BMW had a problem with motor mounts in the past and he inspected them also with no concerns.

Your post is very helpful for me because I was also at dealer with that problem and he told me: I do not know how to adjust idle speed/it is not possible to adjust manually and the idle speed is managed by ECU electronically!!
So do you know exactly how they adjusted it on yours?
I am sorry, I do not. However, the technician is either misinformed or lacks technical expertise. I do believe that the procedure for adjusting RPMs is in the shop manual. Actually, I was talking to the tech when he said, "I'll get the RPM setting adjusted after the software update." If he doesn't know how, have him call GulfCoast BMW Motorcycles for peer-to-peer advice. It was running at 1900 2000RPMs at 8:00 yesterday morning and 1450 to 1550RPMs at 9:30. My guy is good but not a magician; he did something that the factory prescribes.
EDIT: The RPM adjustment is a documented service on the warranty repair order. Described as "Technician observes high idle speed. Technician reset computer adaptations...reset factory settings"

My problem is that I live in Spain and as I see there are no dealers that knows something technically about BMW... all they can do is an oil change...

I made an appointment with the dealer, I told them they should reset the idle actuator calibration. See if that helps.

Just to be clear: that 1700/1800 idle is with the bike fully warmed up? Both my former '22 and my current '23 flip-flopped at 14/15 when warmed up, but had a higher idle when started up cold?
By the way:
1) Was your bike in the shop for something else, routine service, etc.? Just curious what prompted you -- or the shop -- to do the software update.
2) My ears aren't very good off the bike (hearing aids) or on (custom-molded ear plugs from my hearing aid office), so maybe that's why I wouldn't hear any strange sounds, if there are any. That said, my C 400 GT has never, to the best of my sensing things, exhibited any hop on acceleration. I usually give it a fair amount of gas when taking off, by the way. So I'm a little curious about that aspect, too (but glad it's fixed for you now).
mine was stable when warmed up 1400/1500 rpm before the update, now after the update its stable at 1700 rpm when fully warmed up, cold is around 1800/1900 rpm
i sent mine in for hopping at low rpm, so at 1400 rpm taking off from a stop light it would hop like the rpm was too low, the hopping also made a sound thats like an engine knock. The hopping was something like if you have less throttle input and you release the clutch on a manual motorcyle, it drove me crazy with only 5300 kms on it and 4 months old. so they checked everything found nothing wrong and they updated the software and it fixed the nasty hopping issue.

Ah, I see. Thank you for your time: that clarified the whole scenario for me.
I'll have to keep that in mind, watch out for the symptoms. I'm not scheduled for anything through the entire upcoming riding season here in NY -- I just got the '23 last October, managed to just get enough miles to have the break-in service taken care of over the winter, and I probably won't get to 6,000 miles before the end of the year (although I might) -- so we'll see what happens.
Thanks again.
I'm glad I read these last few posts. Mine is going in for my first service Saturday. I was going to tell them not to do the software update, if there was one as I had heard that the update set the idle much higher and my bike is running fine. Now I know to tell them that after the software update (if there is one) to check and reset the idle if needed. I'd like it set close to where it is. There is a little rumbling when I take off from a dead stop as the rollers take position (no hopping) this seams to be normal to me as all of my Vespa's with a similar transmision did this same thing. Even my Piaggio 500 did this. The bike does not seem to be as smooth at speeds under 45 mph as it is at speeds above and is really smooth at around 50 to 70 mph and this also seams normal to me. This is overall the smoothest scooter I have ever owned.
Interesting. I am not being backhanded here....I actually believed they could not service the bike under warranty without applying a manufacturer's software update. Now that I am thinking about it, I have no idea why I believed that all these years. Another reason that I like these forums.
After the last software update and idle speed adjustment the bike is even more impressive and absolutely butter.

Even though I'm having some high rpm issues after the update, I recommend doing the update because if you use a phone and a sena or something similar, you will see significant improvements in bluetooth connectivity. The connection used to be very unstable, I often had to reboot the phone/tft/sena to get it to work properly, but after the update it is now very stable even with two people connected to the TFT.
Glad to hear the software upgrade is working better for you! There was another owner here that let us know there are different software updates, at least one for the display and another for the ECU. I think the ECU update is the one that was causing the problems with rough idle/overall performance. I was under the impression that the software version listed in the display was for all systems. Turns out it likely is not the case.

Yesterday my C400GT was at the dealer for an idle actuator calibration and guess the result.... 1400-1500 at idle now! So now I can say this with certainty: if anyone has an increase in idle speed after the update when the engine is WARM, you should do this procedure, because it seems that it should always be done after the update, but the dealers, at least in Spain, have no idea about it!

Forgot very important thing: oil level sensor is now working again! So it was not working because the ECU didn't realize that the engine was idling when I was standing still (because of the high idle)!
That makes total sense and answers a question that has been floating around this forum. Thank you!
So I dropped my bike off at the dealer today for my first service. (finally) I asked them about the software update and told them what I read on the posts in this forum. They made a note that if there was a sofetware update to check the idle and reset to 1400-1500 rpm. I know they have sold a few scooters but they were not aware of the idle reset. I did not check the software on my bike before dropping it off as it has been on a trailor until today. keeping my fingers crossed.
