We bought an '07-plate VW Golf from a dealer four months ago. The ESP and ABS light came on, and they've said since our warranty is out they won't fix it. They've said to contact VW dealer, but want £75 to run a diagnostic on the car first. After reading on forums that this part has a known fault that VW are aware of - where do we stand in getting them to replace it? I've heard it will cost us over £1000 for the part and labour. We only bought the car from them four months ago.
