A client recently had a problem with his 5 series car starting and then stalling.
Ultimately our diagnosis led us to the fact that the fuel transfer between the left side of the fuel tank and the right side was not occurring….
The fuel filter and pump appeared to be the original items. Fuel filter should be changed every 60.000 miles.
There was fuel in the left side of the tank, but not the right side where the fuel pump is located.
A weak pump can cause this issue, but given the age of the vehicle and after consulting the client, the decision was made to replace the pump, transfer tube and filter.
The fuel system is now running as BMW designed.
