My ABS problem update

[marty72]

Have just bought a code reader from ebay (gives code numbers and what they are) Checked it out on car tonight it checks most systems on the car but not the one i got it for ABS prob!!! How can I find the fault if all the readers that have been pluged in all say the same thing " un able to communicate with system" (this includes main dealers comp) Anyone came across this problem before?

That means that the ABS module might have corroded terminals/connectors or might be toasted...I would start with replacing the abs controller with a known good one. Scour the breakers yards or ebay for a 2nd hand unit or inspect yours for corossion and clean thoroughly.

I have checked the connections at the control unit and all aok,I've been told that the control unit on my car is a rare one (just my luck) are these units inter-changeable or do I need the same part number? Cheers Lex Luther for the link,car goes into an Audi specialist on friday for a service hopefully they'll come up with something. I'll keep you posted. M

Well had ABS checked whilst in the the service on friday looking very like the control unit is shot why is it never the cheaper things that go??? And to add to my happy times the heater motor has started to play up if I didn't love the car so much I'd trade her in!!! Ssshhhh don't tell her
