That's good to know. In many cases I believe it's pointless paying main dealer prices as they're only following the information that comes up on the diagnostics and replacing parts - something any independent can do.
Happy to say I've had no further issues since I had the DPF cleaned.
Happy to report that the dealer got the problem fixed, Loose pins in connector to throttle. Car has been ok for 1000 miles. Impressed with the high quality if dealer service, They stuck with the problem until they were confident of the fix, Will get all future service work,
