Can't believe it - just before 70,000 mile service the VR starts running very lumpy. Had a diagnostic done by local VW dealership & they report a cracked cylinder head costing over £3K to replace (obviously not an option) but said we could try & get it skimmed. Any idea of what this may cost & where to get it done (Herts). Also reported that I needed to replace the oil rocker switch, the water pump, coolant housing & cooler, plus rear bump stops, oh & a chipped fog light thrown in for good measure. What to do, up until a week ago it was a great runner just passed MOT
