Hey guys. Couple questions.

Stomped on the car the other day in 2nd gear and the DSC check engine light came on saying there is an issue with the DSC and be careful accelerating and taking turns.
The code that came up for it is 29CF
(Read from JB4)
After searching most ppl say that's a cinder misfire code or injector. If that's the case why is the care telling me there is an issue with the DSC?

Also, I have another 30FF code and im taking car to dealer tmrw as its CPO'd.

Do I need to clear the codes with the JB4 before uninstalling it? I'm worried that the issues may not come up or that the dealer cannot reproduce situation.
So I don't want to use the JB4 to delete them but then I also don't want any hidden tuner codes to come up when the dealer is looking at the car...

Any help would be awesome. Thanks guys! Love this bimmer community!

J.D.

Can anyone help me with this please?

Don't know what to tell you, but I had a persistant DSC error that would surface every now and then, usually under WOT. It ended up being some bug in the DSC software, and was fixed with a reflash from the dealer. I spent a long time tracking down causes. The assumption that something is mechanically wrong is normally a good one, but not always.

Does your error occur when bypassing the JB?

Just take out ur tune without clearing codes, I have done that in the past and dealer didn't say anything.
