Buying used E90 M3 - need help with ECU readout.

[slidewayscoupe]

Hey all I’m purchasing a used 2011 E90 DCT comp package from a BMW dealership. They provided me a print out of all the fault codes that can be read off of the car. I wanted to see if there’s anything alarming on there that I should be concerned about. TIA!

All left also after trying to clear the codes ?

Looks like a dead battery. Possibly after an alternator failure.

Not necessarily. There was no lights on the dash at all - these are just residual faults existing on the car as-is.

Anybody see anything major?

If you’re seeing that with a known good battery and a known good alternator and it persists after clearing, that is worrying.

If they go away and don’t return, no problem. These cars will throw up a lot of codes if the battery dies, and there’s nothing there that doesn’t appear linked.
