    Hi All i have a few issues
    Its a 99 S-reg A4 Avant 1.9tdi se manual
    My indicators have stopped working this includes hazard lights but they flash when i lock or unlock the doors.
    The temperature from the central display in the instrument panel has completely disappeared and i have not got any heating regardless of what i set the temperature too, the rest of the instrument panel displays correctly.
    I have 2 relays the 267 (A/C clutch relay) and one of the 373 relays tucked up at the back under the steering wheel these are clicking like mad
    I swapped the relays with know working ones and the faults still occur
    does anyone have any ideas.


    cheers

    Sounds as if theres a bad connection/resistance/corrosion on the heating/ac side of things.

    Is the blower motor working just cold or not at all ??

    Has to be water related, too many things un related to go wrong with any other fault

    I agree with mark, too many different systems going wrong... check the seal under the ECU box, as its right above, as they do perish.
