Hi all. I have an 2007 a6 avant both rear indicators are not working. front indicators and side repeaters working fine. Bulbs ok, wiring from convenience module in osr quarter panel to indicators ok. Bulb holders not corroded. Earths all good. Fault codes 01501 and 01505 left and right indicators cut in, short to earth. There is no output from convenience module when indicator on.

With rear indicator bulbs removed there is a voltage output of 0.48 volts which i take is for bulb monitoring?

The car has been stood for approx 2 months and battery was very low when started.

Plugged another convenience module in and fault read. Same 2 indicator faults.

Can anyone give any advice or help to rectify this fault as i am struggling to work it out.


Thanks
