Just got back from the dealer (cardfiff) and the service manager is 100% sure its a duff diff that is causing my noise, in fact its the worst diff noise he has heard. So it looks like it will take more than a few days to get this one sorted. The noise was present from pick up but is much worse now with 650 miles on the clock. What bugs me is that it is now costing me money, 2 trips so far to the dealer 40+ miles, cost of changing my insurance to suit the loan car (little Volvo) etc and I have to replace any petrol I use in the meantime. Service manager said this should have picked up on the pre del prep (already spoke to peterborough). At least the car should be silent when I get it back.
