    This fault started last week and has been coming on intermittently. The pads have plenty wear left on them. To rule out the fault on the pads themselves, I disconnected the pad and connector, and on the other half of the connector I bridged the gap with fuse wire. Fault still there - so it's the plastic connector. I cut off the connectors, and joined the wires together - fault cleared. Only trouble is this is part of the ABS loom, and I'm not paying top dollar to strip the whole lot out because of a dodgy connector. I plan to strip in a new connector, solder the wires then shrink-wrap the cable so they're as good as new. Will any VAG brake connector work - like this for example? Cheers for any advice.

    How about a trip to Overtons (or Sharpewood or Frasers in Huntley, or Persley maybe)?

    You could then chop off what you need, and know it is the right bit.

    That DOES look very like the part you want, though.

    I'm the same, so I don't know what he has in.

    It's still Stan, though!

    I've never been to Overton, however they dismantle the cars themselves, so they'll probably strip out the entire loom which is no use unless it's dirt cheap. Few A4s (B5/B6) and even a couple of A2s. Link here: Overton Vehicle Dismantlers ( Aberdeen )

    I have issues with Overtons now (thieving git issues!!) but to be fair, if you are after stuff that is non-standard, they may take you out back for what you are after.

    I usually try on-line for stuff - but generally only where I can call and chat.1 minute chatting will tell you if the guy is worth dealing with. Of course, you can always try Aberdeen Audi..... (I DON'T generally have thieving git issues with them!!!!)

    Spoke to Aberdeen Audi on Friday - as I was picking up filters to service my wife's car. They only sell the entire loom, although there is a part number on the connector - so I might look into this further. I asked to look at a brake sensor from a Q7 - same thing I posted from the link on Ebay. The male connector on the Bosch pads - looks like it will fit the sensor wiring from the Q7. They're only a fiver off Ebay - no way I'm paying £20. Got a good price from Aberdeen Audi for genuine water-pump, thermostat, full-timing belt kit and ancillary belt for £200.

    Went to Persley - talk about a blast from the past. Loads of folk stripping stuff out of (what has to be said are some fairly **** cars). Only two Audis there - an early A6 2.8 Quattro and a early A4 (R plate) but no pad sensors. I did clip off what looked like the same connectors from the A6 but I suspect they were for headlight washers. Don't fit anyway. Got them for free - so no big deal. Still looking!

    Quick update. Finally managed to source a new connector from shop4volkswagen. Part number is 1J0 973 702. Postage was more than the part, and it's the plastic casing only, it's not wired! :banghead:

    000 979 019 EA is the part number for one 0.5mm cable with gold plated contact pins that fits the above housing.

    The cables come with a pin on either end, so you cut one lead in half to get two pins, however there appears to be a minimum order quantity of 5 leads.

    Speak to Jason.s off here, i'm sure he'll be able to sort you them out for a decent price.

    Cheers for that - I made something up myself with 0.5mm cable which I'm sure will work. It's a bit Heath Robinson - but it'll do. At least it's waterproof, so should last.
