Hi to all,not been on the site too often lately as been swattin up for exams! But my baby is suffering in this heat (i hope its the heat?) I was driving along when the display started bleeping at me telling me the abs was not functioning correctly and then went off again after a couple of miles! then a few miles later it came up again! it seems an intermittent fault or is this normal? The brakes feel fine and the fluid is at the normal level. has anyone come across this before? could it possibly be the heat?
any info would be great! cheers Lee

I can think of 4 suggestion's

1) check it out with VAGCOM,
2) it could well be time to change the brake fluid
3) broken ABS rings
4) dirty sensor's

just my thought's for what their worth

or the abs ecu, same as mine went... for about 4 months now its permanently on, abs doesnt work at all.
try Vag Com, if you cant connect to the abs module its defo the ecu. theyre about 250 exchange ive yet to get one!

Mate has the same problem,his is the ABS ecu think you can get them on e-bay.

Very common problem, will affect everyone eventually!
You can fix it yourself (bit tricky and not guaranteed)

Usual fix is to rplace the ABS module (NOT THE COMPLETE ABS UNIT) which is easy DIY, with a reconditioned unit from someone like BBA-Reman

I would also place my bets on the ECU. And like UKS4APR1 said, don't buy a new ECU yet! This can be fixed. It is most likely your problem, if one of your sensors is not dead.

Thanks for all the info chaps! its much appreiciated. will try out the abs later to see if it works? will possibly be another post soon about S4 breaking for spares if the ABS has failed! cheers Lee

Lee im from staffs too, do you have vag? i could have a look for you saturday morning or something.

Hi Oli,that would be great! i am based in Tamworth, where are you? i dont have a vagcom so would be good to see if anything else comes up? i think i can poss fix the abs module as i have done lots of soldering.Tomorrow would be good for me,where you thinking of? Cheers Lee

Hi mate, if you can fix yours maybe we can do mine too! haha
tamworth is pretty far from me, about 45mins can you get up north a bit towards stoke/newcastle way thats where i am.
Oli
