Interesting past week... Monday, filled up, Tuesday last week, got a whiff of diesel on the way home from work. Many lorry's in front so didn't think too much on it.
Wednesday going for a blast up the A1(M) to Baldock services to get a coffee... stronger smell of diesel... oh dear.. guess it was coming from me. Quick look underneath... nothing to worry about. Drove home.. looked under again on the drive.. Drips of diesel... alot of drips! from underneath the tank.
So, car up, removed under protection. Fuel lines all looked ok, tank looked ok. drips stopped. Looked at schematic on ePer and decided to start it up to see if issue was with the return. Without the underbody protection very fast drips/trickle. No obvious place it was coming from. (somewhere higher up)
Try to get to the inspection hatch ontop of the tank, That rear seat is a PITA to remove in my early 159 with fixed rear seats, finally got in there. About 4 inches along the fuel feed from pump forwards was the split, just out of sight and not a job I could undertake at home.
To the local garage. Finally after having to wait for new fuel lines to arrive from Italy, they were fitted yesterday and (thankfully the car passed the MOT once this had been done).
I don't know if others have had this issue or if it is age related wear, Mine is an early 159 with almost 200k on the clock.
Possibly an issue for others in the future?
