In for service - Lost ABS, Lane Assist, and Eletronic diff
For me, it came on when I turned my blinker on to get into the right lane. The right front wheel ABS/speed sensor on my W213 E63S has gone bad and needs replacing. I made the code happen, drove home, didn't turn the car off, plugged my OBD-II reader in, and pulled DTC C0034 and C0034(08) from it. Apparently this is a super common problem with W212 + W213 models? I'm wondering if I f*cked my speed sensor up pressure washing the wheel area. The part number is A2135403605 and I see it online for $15.
Warning: I'm not a technician and I didn't actually buy the part yet / get it fixed + confirm the problem goes away, but this really does sound like a great first start.
Now to argue with the dealer that this isn't related to my tune with my nicely new voided warranty
