My 2005 V/W Golf Plus has been serviced fully by my local VAG garage and was in for service + MOT 3 weeks ago, however last week the ESP light came on and diagnostics showed the ABS failure. I was quoted £450 to have the fault rectified by use of a kit now supplied by VW. and when I questioned this I was then told that as the car was 2 weeks over the extended V/W warranty of 72 months for the ABS fault then they would pay 2/3 of the cost and I should pay the remaining £150. In your opinion, is V/W liable for the whole cost and is it worth me pursuing them for the £150 it has cost me for an obvious fault of their making?
