My four year, 3 month old Golf estate has just needed a complete EGR system replacement, ie cooler, valve pipes and gaskets. The system had becone completely clogged. Parts alone were over £700 and the labour £650. The car has 46.5k miles on the clock and has been regularly serviced at a main dealer. In August 2012 there was a fault with the DPF regeneration, which was fixed under warranty. Otherwise, nothing else to report. The car is regularly used on motorway/main road runs and infrequently for short, or traffic snarled hops. I have been in discussion with VW Cutomer Care, who admit that this fault usually occurs at mileages around the 100k mark, so my car is unusual. They have agreed to pay for the parts as a goodwill gesture, but will not contribute to the labour costs. I feel that this fault should not have occurred on a car of this 'vintage' and am considering taking things further to recover more of the cost. I dont consider this to be reasonable wear and tear.
