    Unhappy Heeeeeeeeellllllllppppppppp....... Major system failure, Mot tomorrow!

    Hi everyone,

    recetly repaired my abs ecu, it's now working, but need to reset the amber abs light. Some strange reason the reader, cannot communicate with any part of the car! Just simply won't talk to the car. What can I check to get the stupid thing to work, it worked before.

    mot tomorrow morning, I'm sweating, it's my only car :-(


    suggestions welcome.

    thanks ash.

    Id try to see if anyone local to you (post location in this thread or iirc the vcds thread and hope someone sees it) that has vagcom/vcds lite if it wont connect to any ecu on the car then at a guess id say its there tool, other than that theres nothing really you can do other that your going for an MOT that is definately going to fail due to the light, so your next P.O.A should be to order a ebay cable so you can diy things like this in the future all you need is basic computer skills and a laptop and of course the ebay lead. I have vagcom and also a hand held scan tool that does abs, eml and airbag and a/trans that stays in the glovebox just incase

    Tool not faulty, works on other cars and mine before. Checked all fuses, nothing popped... So really banging my head against a hard wall. Going to speak with an auto sparkle tomorrow :-(

    Could my repaired abs controller be causing this issue?

    Id expect it to read the other ecu's personally, if it was the abs controller it just wouldnt read the abs ecu.

    Well that's we both thought, I've heard of abs modules failing newer systems though, so just got me thinking?

    it could well be the repaired unit, when i was trying to diagnose a bad airbag module communication a faulty abs unit can block comms to all sorts of other controllers, if you disconnect the abs ecu i.e pull fuse or better still the actual plug on the unit try scanning other ecu's if you get comms then you know where the problem is

    Faulty unit can block comms for sure, Our ABS controller of her TQS has taken a dump, but all the rest still work.

    Who repaired it?

    Abs unit started playing up again today so either going to repair again or replace. Put through mot to see what else is needed, brakes out of balance by 71% ?!? So gonna take off road this week and give the old girl a good seeing too. Or sell... We shall see.

    Unplug the ABS unit and see if you get comms back.

    When you say brake imbalance, what do you mean? They shouldnt be testing a quattro on their roller brake tester anyway, they should be taking it out on the road with a decellerometer.

    no idea how it was tested. But I'll be making a phone call tomorrow. The piece of paper says they out by 71% but the car brakes straight!?!

    Do you have a brake test print out picture ??

    as above if they did put it in a rolling brake tester i certainly wouldn't be taking it back to them and be having words.

    Think they think you have a B6 1.8TQS you need part beginning 4D0, 8E0 is going to be a B6 platform abs module.

    8E0 614 111 A is the part number on mine, and the one I took of my breaker was the same, not sure why it has the E instead of the D.

    Yeh the B5's have 8E0 pumps for whatever reason.

    I believe 111A or 111E both work.

    They're fitted to quite a few cars, including A6 and A8's and some Passats.
