Wiring Diagram

[djmotorsport]

In the past month, my S3 (2001) has started to intermittently show the brake pad warning symbol in the DIS. I’m looking for a wiring diagram of this part of the loom so I can trace the issue.


The battery is new (problem occurred before the battery was changed)

The brake pad sensor connector in the front lhs wheel arch has a loop back connector on it as the pads don’t have the requisite connector. It has been this way since I bought the car 14 months ago.

I think it’s probably a faulty connection somewhere between the loop back and the DIS but need the wiring diagram to check this theory out.


Anybody got one, or a better idea of what the problem could be?

Dave,

Haven't seen you around here for a while, hope the car's still running well. I assume you've tried the obvious and followed the cable up through the wheel arch? Have you tried to see if you can clear the fault with VAG-COM? Sorry, not much help on the wiring diag.

Chris,
Car's running great - not getting used too much at the mo as i'm working in the city centre and parking is very expensive.
I started to try tracing the cable from the wheel arch yesterday but my pal turned up with a broken kart which took priority And karts are also the reason I've been absent from here.

Don't know if VAG-Com would help as the fault comes and goes - If I can't get a schematic, I guess i'll poke around some more next weekend........



I think the award should go to Glen - It's all his good work!

Have you checked for continuity on the loop back connector for a start?

 

[djmotorsport]

Yes - I should have said that I have 2 loop backs, both which show 0 ohms and neither of which fixes the issue.

 

[Secret Squirrel]

Ok. I thought that would be a good start.
I can see why you need a circuit diagram. Tracing the cable could be a PITA.
Sorry I can't help, but have you got part number on that loop back connector. I've been meaning to source/make one of those for a while. That DIS warning gets on your nerves.

I was actually wondering if it were possible to just switch the sensor off with VAG-COM. If your pads don't have the wear indicator you wouldn't really need it on.
