Ooooh,there's a question.
I think the last one was on the Ibiza. Not sure if they came fitted to the new hub or not though.
That was fine for a couple of months until I came home in a particularly sporty fashion, lobbed it into a tight left hander and then the dash lit up with warning lights and buzzers went off. I pulled over, thought for a minute, switched everything off, counted to ten and switched back on...
SWEET! All is fine again, then drove home.
Next morning left home, turned left at the top of the road, down the hill to the right turn, braked, crapped myself a little as I overshot the turn due to what felt like a rock hard brake pedal with a jackhammer under it pounding my foot.
I've experienced ABS often enough to know this was ABS turned up to 500! With about 25% of the usual braking.
To cut a long story short, I fitted a new brake master cylinder, then another one on the advice of a so called VAG forum expert. He is good by all accounts, but rather wrong in this case. Then the ABS ECU was sent away to be tested. No fault found. BUGGER!
Then some bright spark suggested plugging into the OBD for some live data.
It turned out that three wheel sensors registered one speed and the osf registered a couple of mph slower. The difference grew the faster you went until the ECUs couldn't take it anymore, threw a wobbly and switched off.
The issue for me was that period between starting and throwing a wobbly. In that time you never knew what was going to happen when you hit the brake pedal: work, work a bit or jackhammer.
Once the system shut down the brakes worked fine.
It turned out that the original hub was faulty.
Since fitting the new hub I've had about 8000 miles of cruising and sporty(caning it) worry free motoring!
Well, all apart from the annoying twit in front of me in that BMW X5 who cut me up then glued itself to my tail as I blasted past him down a little quiet bit of dual carriageway at 85 until he put his blue lights on......
