Dionysios,
Do you have ESP? If so, switch it off and try accelerating hard to see if you get the ABS light flashing again. A scan with VCDS would also help.

abs !!!
A failing maf caused this on my s6....
If you have vag com...test the maf.... the test is.....with engine idling....rev the engine up to about 5000 rpm....there should be a proportional increase in the values of the maf reading...if it falls aways then you know the maf is faulty....

My S8 also does this, usually passing through about 90mph. Accmpanied by a second or two of roughish running, like a minor misfire.
What's the MAF?

 Tends to do it only once per outing, usually during the first transition from 'normal' to 'warp drive'.

Fitted new MAF as car running like a coo after being serviced. Prolly fitting the new air filter disturbed a faulty MAF.
Purring like a kitten now. ABS and exclam mark no longer appear, so looks like MAF was the culprit all along. Cost was £65. Easy to fit.
