AWD problem

Mobil088 · 03-08-2020, 12:07 PM

I have been getting 4x4, dsc and brake light on my 335xi. It’s fbo with mhd stage 2 tune. Only when I do hard accelerations. The car jerks, the rpm fly up the tach and goes into limp home mode. An the 4x4 dsc and brake light comes on. As soon as I turn the car off the lights go off and it drives fine again until I floor the gas pedal again. I use protool to read code and the only codes showing is 55C3 and 5F2F. No other codes

start with the basics. ABS sensors.

Then the tc oil.

Then the actuator.

And ultimately the tc.

Also when my subframe was rotated and got my crawling issue , I had this message 3 times until I reach the alignment garage. Those system are very sensitive.
