Hi all,
My A2 (2001 TDI) has had the glow plug light flashing for quite some time. The fault code given was for implausible signal from the brake switch. I have changed the brake light switch for a new one, and the fault code has remained. I have cleared the codes with VCDS Lite, but the code immediately comes back. I have copied the VCDS Lite scan from today below.
I have done some research on the forum and tried reseating the brake bulbs, new brake bulbs, disconnecting the clusters, and disconnecting the high level brake light. The flashing warning light and fault code remain. The last thing I am going to try is take apart the original brake light switch and clean the contacts and refit it, though as the new switch didn't work I doubt this will.
I've also got a code for the Yaw rate sensor, on a couple of occasions I've had the offside front brake being applied by the ABS system and then it putting on the ESP warning lights, I don't think this is related to the glow plug light/brake switch issue.
As a priority I want to get the brake switch code sorted, as the MOT is due in about 3 weeks. At this point I'm not sure what else I can look at. Any tips?
Thanks,
Tim
