Having issues with my 2011 a4 2.0tdi Quattro.
have all kind of lights on dash like abs, traction control etc. plugged it in and got these codes, also voltage is pretty low while running only 13.1v and when engine off drops to just under 12v
01316- abs control unit
00458- battery monitoring control unit
03705 - voltage stabiliser
00287 - right rear speed sensor
00473 - parking brake module
plus a few others.
from what I have read all these are linked, have changed battery & coded, changed alternator and changed speed sensor, anybody else had these issues or know the cause? Possible abs module? Help would be much appreciated
