    Hi, I swapped the climate control module on my 2001 A3 TDI because the buttons were worn I put a second hand one in but it did not work I then put my old unit back in and that will now not work. I had it checked on VCDS and it will not connect with module 8 wich I have been told is the aircon unit.

    Any help would be great :uhm:

    No nothing on display none of the buttons do anything only thing it does is illuminates the buttons when the headlights are turned on.

    I have checked the fuses by the steering wheel are there anymore for the climate control?

    I have checked and rechecked the plugs in the back the only thing is that I have noticed is that there are 5 plug sockets on the back of the panel but only 4 plugs coming from the car is this normal for a 8l A3?

    Thats what I thought I have spent a lot of time looking for the missing plug and I just assumed it was not there. I will check for it again tonight when I get home from work.

    Thanks for all the quick replys guys

    Looking at Elsa Win looks to be 4 connectors that I can see that should be connected B ,C, D and F . The main power feeds are on connectors D pin 15 and C pin 4. The fuse numbers are fuse 5 a 7.5A one and fuse 25 a 25A one.
    The power feed wires are black with a blue tracer.
