I found wires that were cut (presumably either by the wreck or after a fire/short that the wreck created) and respliced in a most half-assed way, so bracing myself to explore this mess. I found one horn wire had not been crimped well at the splice and pulled loose. When I put it back together I...

I finally broke down and investigated under the car. Found the bundle of wires along the passenger fender has been cut and spliced back together. So now I’m doing my best to decipher wiring diagrams from Haynes gasser manual and hoping they aren’t significantly different from my TDI. ☹ I’m...

This link does not work. Does anyone have a functional link for a fuse diagram (2012 Jetta tdi)

I'm baffled that it's so hard to find a diagram of the fuse box. I saw a link in this thread but the server was not found. I see multiple places in google image search that show the horn relay as fuse 52 under the dash. My car has no fuse in that slot, but I saw a photo of another person's car...

New-to-me 2012 Jetta. Turn key, dashboard activates. Turn to start, accessories off as expected but no starter. After a few turns (sometimes first try, sometimes 2 or more) it eventually cranks strong and turns over. Battery tests good. Ignition switch? Other ideas? TIA, K
