Recently purchased a 2010 e90 with 130k miles.Runs and drives great but dash in on like a chrismis tree.Traction control,4x4 and brake light on.After a scan I’m getting these 2 codes which I believe it related to the issue 55c3 and 6DC7.It says the car is in limp mode but I don’t believe it is as it drives fine.The other code is for steering angle sensor.I have tried to turn and steering wheel right to left to recalibrate but it did not fix it.Where should I start from?

Those two codes are both for steering angle sensor, which can be calibrated with software I think Bimmergeek Protools can do it, but if not, INPA/ISTA.

The lights themselves usually correspond to a wheel speed sensor... is ABS also lit?

Abs light is not lit, I have tried calibrating it by turning the steering wheel from right to left with no success and even tried a known good battery and tried calibrating it again still light is still there.I am going to clean the steering angle sensor next and see if that fixes it.

My best guess is you're going to need ISTA.

I cleaned the disc and now the code went away but I’m getting more codes now from before all relating to the steering angle sensor.I used acetone to clean the disc could that have damaged it.These are the codes I’m getting 55D0 passive,55C3,94B6 and 6EC4
