Hi new to the page need some help
Got a 525d and fitted a new fuel pump in tank and everything going was great in till used all the fuel from right side and all went to left side can't Figure it out had about 3 pumps now do I have to reprogramming something or reset engine management and how does.it lift fuel from left side to right thanks
Good day, Im having the same problem like you with my E61 525d M57 engine. Did you manage to solve the problem?
Thank you very much.
Hi guys, I know this is a very old topic, but it's still very relevant for someone. I think I have a completely identical problem. Both units are brand new from BOSCH. I've taken them out several times, checked the connections, etc. I don't know what to do next. I'm starting to suspect that the problem may be elsewhere. Somewhere around the filter on the inlet, a blocked return line, etc. Because pumping from left to right drives a reverse flow of diesel from the return line. In the service menu, you can observe the movement of fuel, which I've been doing for the last few days. The last time it happened to me that the car stalled and wouldn't start, with about 12-13 liters of fuel remaining in the left half and the right half empty. After refueling, it keeps going. Depending on the fuel level in the hidden menu, but also in the diagnostics, the fuel sometimes moves from right to left, after turning off the engine and starting it again it starts moving in the correct direction from left to right. Has anyone solved this???

It could be due to a lot of things. Use a BMW-specific code reader instead of the hidden menu.
Thanks for the response, of course I do that. There are no errors stored anywhere, only error 4587 in the ECM - fuel filter heating.
I only use the hidden menu in the cluster to monitor the status of the left and right halves, these values are identical in the diagnostics.
