can anyone help me identify what the big 40amp fuse in the boot is for please, mine has blown and it has no mention in the manual, its a bigger than normal size fuse and being 40amp pretty sure its for something important !!
tried looking online but had no joy..
thank you

That I would doubt..........

If that is the case, I would put a tone generator on it, and ring it out to see where it goes.

Maybe check the WD again or component locations.

You need the repair manual here.......

www.erwin.audi.com

Trying to use the forum as a replacement for the repair manual, is a bad idea, especially when a business.

I'm not trying to use it as a repair manual, was just after some help which I thought this forum was about ? tried Erwin but no joy

You need to go back to Erwin and read the WD diagrams and component locators.

If you are in the unknown..........take a tone generator and run it on the track........follow it to a component you can observe on the WD and back trace the tracks.........

Using procedures like I stated, will help you become better at reading and following the schematic.

Hmm, strange. :confused:

Was the erwin site down when you tried? (I'm being genuine here - not sarcastic). Just I obtained a day subscription in the summer and I was able to download everything, including TPIs and TSBs for my car and my mate's TT.

Have you missed that they are called 'Current Flow Diagrams' rather than Wiring Diagrams on Erwin? Also Jack's URL is slightly different to the address from the UK. Try https://erwin.audi.com
