i bought my car used ,after a few months i had the dreaded ABS problem .the car was 3 years 4 months old with 22000 .took it to vw dealer who charged me £89 to diagnose and a quote for £1206 to fix,when i asked about goodwill they gave me a printout and told me i did'nt have any.I spoke to the service manager who admitted it was a well known problem but said he could not do anything about it and if i wanted i could ring vw customer service.
fortunately customer service were much more helpfull ,i oniy had a small contribution to make and customer service were calling me twice a day to make sure the garage were doing what they had been told to do.when i went to pick the car up the staff were all of a sudden very helpfull !
then a few week later i had a call from vw doing a survey on how customer service and the dealer had delt with me .i was able to let them know exactly what i thought of the dealer
so if the dealer has been rubbish let customr service know.
