Hi guys,

Just wondering, is the abs and Psm linked to the functionality of the tiptronic buttons? My rear left wire harness for the brake pad/speed sensor broke into half triggering the abs and psm light to be illuminated. From tat instance on, my tiptronics buttons were not functioning and my digital speedo stayed at 0km/h.

Cheers

The Tiptronic control unit does use speed inputs from the wheel speed sensors, so I'd say that it's highly likely that the problems are connected.

Very likely. For example, on the ZF Tips if a wheel speed sensor fails (P1710 right front or P1715, left front), then your tip shift buttons on the steering wheel will not work.

Buy and install new speed/brake wear sensors.

His wiring harness broke - not his sensors

Bro. The last time was the right rear brake sensor wiring if I remember correctly. Are you now saying the left rear has gone as well ?

You're not having a good run these last few months. Hope you get things sorted out.
