    pim trying to find out what runs from it, I no the clusters do as it says that on the door, but even after removing them it still go's can anyone help or point me in the right direction. I'm thinking a trapped wire or something else faulty but just need to no if it feeds anything else, thanks

    Hi what does the manual say fuse 5 protects as you could start by disconnecting each consumer ,I don't have my manual to hand but a stab in the dark would be a coin dropped in the lighter socket if it's protected by that fuse.

    I have just done a quick Google search and I found one entry that says it might be linked to the AC.

    Is that the fuse 8 inside the car or under the bonnet, I've been searching for bloody hours , but found out that the S3 fuse layout is different to other models thanks
    It's a red and yellow wire that's at fault I think and it a thick wire so must carry quite some power or feed quite a lot

    I did just a quick search. I have an A3 and it's not hear. Also just read it might be part of the wiper and washer

    Commonly with ac it could be your compressor clutch coil or the regulating valve on the compressor or the wiring rubbed through
    If that fuse supplies the climate

    also you could do a scan with vcds and see what it says.
