I have a problem with my 320d. It's 2007, M Sport (e92) with 81,000 miles.

The problem started 3 days ago when the engine cut out while driving and the engine management light came on. I could re-start the engine but it was struggling and would not rev past 1500.

I got the car recovered in the end and once home, I ran diagnostics which gave the following codes:

Zylinder 1 Control / Glow plug cylinder 1
Code: 4A64

Rail pressure quantitative plausibility control
Code: 4560

Rail pressure quantitative plausibility control
Code: 4570

Rail pressure-pressure-controlled plausibility
Code: 4610

Throttle actuator
Code: 483D

Rail pressure-pressure-controlled plausibility
Code: 4600

Rail pressure-pressure-controlled plausibility
Code: 4630

Rail pressure quantitative plausibility control
Code: 4590

Rail pressure monitoring
Code: 4B90

Today the fuel filter was replaced and after priming and cranking the engine seemed to start easier and idle for about 5 minutes before cutting out.

Tried again a few times and back to square one, it will idle but won't rev past 1500.

In INPA I read the status of the fuel bump (see screenshots). My observations are that the actual pump speed is about half the target pump speed, also the pump motor current was fluctuating between about 9.7 and 11.5 rapidly.

Does anyone have any advice as to what could be the problem?

Thanks

The electric pump is just a low pressure supply pump for the high pressure pump.

I guess either could be faulty though.
