Hi, newbie here, would appreciate any advice.
I have a 2007 320D e90.
A few minutes after driving off, my traction control starts cutting in, dropping the revs, and flashing the dash warning light. Soon after, the stability control will fail, followed by TPMS failure. If I disable DSC and DTS, [long press] the car drives normally.
At start up, there are no warning lights on. I scanned the obd with an OBDLINK MX, no error codes, but I'm not sure if its only scanning the engine ECU.
Battery voltage and regulator appears perfect.[14,5v on driving]
I cleaned the rear wheel sensors, I'm thinking one has failed, but surely that would show a permanent error that needs resetting?
Before the problem occurs, DTC and DTC work normally, if I push the car in a corner, both systems cut in as normal.
Break fluid level is normal.
