I have a Superb Estate SEL phev Oct 24. Currently I'm experiencing intermittent grinding when slowing down. I believe it might have something to do with the regen. Intermittent jolting when accelerating I believe this might be due to the double clutch slipping. Finally, whenever I go to Heathrow the map navigation loses position and plots me in a completely different area which then affects the dynamic road sign system causing the car to break and slow down on the motorway because the car believes is travelling on a 30 mph Road. It recently had a software update which took 3 days. Has anyone else experienced any of the same faults as some of them are intermittent and the dealership are struggling to them?
