Hi everyone, I have recently had my offside rear ABS/speed sensor replaced at Audi, after my Abs & Esp lights came on & my gears were all f****d up when driving. Head the car back over 3 months now & the Abs light is on agin. Sometimes the Esp light will come on too, but car drives as normal. I don't know anybody around the Swansea / Port Talbot area with a diagnostic machine. Any Ideas? it could be the longitudal sensor, but without going to the Stealers & paying £107 just for 5 minutes I'm lost. cheers guys if any of you can help.
