I have a 2005 Passat TDI with 51K miles on it. Recently, the car has been â€œmissingâ€ under acceleration. If it was internal combustion I would suspect ignition wire, distributor, plus, etc. but its not , its a TDI. I did have an egr fault which occurred after the problem started. Cleaning the egr removed the fault but not the problem. The â€œmissâ€ occurs under constant acceleration, mostly between 45 and 70 and dissapears if the turbo kicks in. Iâ€™ve changed fuel and even added a cetane booster to no avail. The local VW dealer wanted $1000.00 to replace the EGR valve so I'm reluctant to take it there. Any suggestions would be appreciated.
