I coded (bimmercode) the car to start in "sport individual", which for me, is sport suspension, and "comfort" everything else. That's how I do 95% of my driving. No problems, no issues, works as it should. While driving, suspension works exactly as it should.

The issue..... is when I park.

I put the car in loading mode (100% of the time, religiously) every time I park.

When I come back in an hour, or 10 minutes, or 3 days..... sometimes it's in comfort mode.... sometimes it's in sport..... sometimes it's still in loading.

Sometimes.... I lock the car, stand there and watch it go back and forth between modes for absolutely no reason at all. I cannot pinpoint any specific circumstance that causes it to do this. Key in my pocket... still does it. Key locked up in an RFID box in the house.... still does it.

Has NOTHING to do with droplinks. It's done this since long before I installed them. I don't recall it doing it before I coded it to start in sport individual though.

Any suggestions?

Don't have an answer and can't test as I don't have air suspension, but to confirm your theory that it may be related to the coding change to initial driving mode, just code it back to stock or just Comfort and observe whether the behaviour follows coding or not.

I agree just make sure when you code it back using your backup file. This way you can ensure everything is coded back to exact parameters before you coded it in order to test your theory.

I have a similar issue with Sport Individual coded as my starting mode. Like you said driving is fine. It is when the car is off and/or locked that i see the suspension doing whatever it wants. I have my Sport individual set to use the lowest driving height. When driving it is fine. Every time i get back in the car though the suspension is on the middle height setting and the car lowers once I enter it. I'd prefer to have it just stay at the lowest driving height all the time. I am concerned about the air suspension components wearing early because it changes settings every time i enter and exit the car which is usually 4+ times a day. Prior to coding the starting mode, if i left the car in the lowest height setting (without going in to any of the sport modes manually) it would remain that way the next time i got in the car. I am going to try and re-code back to default this weekend and see what happens.

Interesting. Assuming coding to Comfort fixes the issue, it would also be interesting to try Sport mode other than Individual ie Sport or Sport Plus and see if the behaviour is the same (to check whether it's the "Individual" that causes the bug or the "Sport". Along the same line, it would be interesting to see if Eco vs Eco Individual start mode has similar issues (as boring as it would be to start or drive in Eco anything).

I tried to code just sport this weekend and same results of the air suspension having a mind of it own. I coded back to comfort and now it stays on the last suspension height on lock and unlock. I will keep it there for now in an effort to not have the height settings change all of the time on its own.

i can confirm that programming to the adaptive mode also causes the air suspension to do weird things. I typically lower the car for exit, but many times if I walk by the car with my FOB in my pocket, the car raises to the standard position on it's own. Crazy.....

I as well have coded it for Adaptive and I always want to drive it at the 2nd lowest position. The things that trigger the normal suspension is when I open the trunk as well as remote start. If I don't trigger those it usually stays in the lowered position.

I have mine coded to Adaptive and those seem to be the trigger for mine going back to normal height also. I don't remember having that problem when I didn't have it coded. I'm pretty sure the suspension stayed in the 2nd lowest position but not positive about that.

[Trojanlaw]

Mine acts the same as X54th ans Turtleboy. I also have Adaptive coded. The suspension stays in the last level set unless I trigger it with the trunk or remote start.

[Ninefourteener]

Good to see that I'm not the only one having this issue.

Mine definitely has a mind of it's own. Activating the trunk, etc.... has absolutely no impact on it. It just decides to revert back to the center level.... sometimes level 2.... sometimes the lowest level where I left it. No explanation.

I had mine coded to Sport and Sport Individual and the air suspension did act weirdly but now I went back to having it start in Adaptive and everything is fine.

[Ninefourteener]

I have to assume this is some sort of error on the part of Bimmercode. "Something" got missed when this was programmed.

I'm actually going to re-code it back to start in Adaptive as well. It seems to be coding it to Sport Individual, causing it to act squirrely when the car is off.

Kinda disappointing actually. I drive in Sport Individual 99.9% of the time, it would be nice if I could code it to start that way, without additional problems.

I had my 45e configured to start in electric individual, this had the air suspension in sport mode. But here also it raised sometime to normal mode. No coding was done....

Something from the manual

Long periods when vehicle is
parked
During long periods when the vehicle is parked, it
can lower itself. This is not a malfunction.
If drive-ready state is switched on with the doors
closed, the vehicle is raised to the normal level
automatically.
Depending on the state of the vehicle, raising to
normal level may take several minutes.

You changed a single FDL parameter in BimmerCode expert mode — this issue definitely isn't BimmerCode's fault. Rather, it seems that BMW engineers didn't anticipate that the default mode could be anything other than Comfort and didn't test other variations in some cases (the fact that Adaptive behaves fine is likely a fluke at this point). That kind of a thing is definitely possible (even likely) with coding since we're changing options that may or may not be on the software test spec sheet. In fact, as much as I razz BMW software engineering practices, it is actually impressive these kind of software "side effects" don't occur much more often with coding changes.

Never went into expert mode.... ever. I have no idea what it.looks like, or how to do anything.

This particular issue seems to impact the car only when parked, if the default startup mode is sport individual.

Regardless it still changes one parameter of thousands.

[kerim]

Has anyone had any updates on this?

Mine randomly does it too. Have it set to start in sports individual

[nZtiZia]

interesting, several owners of the 45e also experienced and reported air suspension levels randomly changing when parked. there's a link between the air suspension level and drive mode as reported above. no coding involved. we haven't found a root cause nor solution.

45e switching electric individual to hybrid https://g05.bimmerpost.com/forums/sh....php?t=1725274

[R34L15T]

Was anyone able to resolve this or find a solution.

Just coded the car to start on Sport Individual and having the same issues the air suspension!

[Bavar-ian]

Coded mine to start in Adaptive and no issues.
Got to try other modes.

[Installsplus]

Just had my links out in. Mine is doing the exact same thing. Has anyone figured this out?
