Hi, first post here but have read many and many have helped so thanks for that upfront
i have an an issue with the fuel cut off on my 300tdi.
10 days ago the engine wouldn't turn off so tested everything & then removed the solenoid and found the rubber part of the plunger had a chunk missing. Ordered new part and fitted and all was well again.
Today, the same has happened to the new solenoid, a piece missing off the rubber plunger. It has done approximately 20 miles since the new one was fitted.
What could be eating the rubber part of the plunger?
Its an expensive way to turn it off fitting a new solenoid every 20 miles ha.
