We hope someone can help as we are now at our wits end and £350 lighter after garage bills with the problem still present.
The car has been cutting out intermittently while driving now for a few weeks. Seems to only happen when the engine has warmed up after driving for a few minutes. The car has had a full service with filters and vaccum pipes changes (no change in problem). Was then taken to our local VW dealer by Green Flag after breaking down again. VW diagnosed a G28 fault - Engine speed sensor. The sensor has been replaced today. We drove away from the garage and almost got home before the car started cutting out again.
When the car starts playing up it is running fine then the revs drop to zero. Sometimes they come back up a couple of times and the car splutters and sometimes the car cuts out completely and wont start. Leave for anything between 5 mins and 30 mins and the car starts again. It only seems to happen once the engine is warming or has warmed up.
When we got home we pulled down the fuse and relay panels, started the engine and waited. After a few minutes the above happened and we could hear a clicking from the area of the relay panels before the car cut out again.
We are thinking relays here but are unsure what numbers are what.
What does anyone else think and can anyone make any suggestions. We are totally stumped and its costing us a fortune. We rely on the car to get both of us to and from work as I work out of town and the wife works night shifts. We have now been without the car for a week and we are really struggling now.
Thanks in advance.
