Technical Service
SUBJECT
Fuel Tank Difficult to Refuel
MODEL
E60 (5 Series) All Models, E63 and E64 (6 Series)
Vehicles produced from 07/04/2004 up to 11/18/2004
SITUATION
The customer complains the fuel tank is difficult to refuel which causes the fuel filler nozzle to shut off repeatedly.
CAUSE
This failure is due to a defective service valve located in the top of fuel tank. The service valve cannot be replaced separately since it is plastic welded to the tank itself
PROCEDURE
1. Replace the fuel tank.
2. If raw fuel is found in the DMTL pump during tank replacement, also replace the DMTL pump and carbon canister at the same time.
Important Note:
When installing the new fuel tank, it is very critical that the hose from the top of the fuel tank to the DMTL does not get kinked, twisted or crushed. Please pay special attention to the placement of the hose when installing the new fuel tank.
