What does this fault code mean?

The code points to a mechanical fault where the pressure at the injection pump for fuel metering on B is too high. It does not point to any specific component. The engine control module monitors the injection system and stores the code only once the conditions for the test are met.

Possible causes

Fuel flow to the injection pump is too high because of a damaged fuel pressure sensor, injector, fuel flow control valve (MPROP), fuel pressure control valve (PCV) or feed pump
Damaged injection pump producing too high fuel pressure

What you can do

1Read and note the fault code, clear it and test drive to see whether it returns
2First check whether the feed pump has any fault codes and deal with them
3Look for fuel leaks and check whether the fuel filter is clogged
4Check the connectors to the fuel pressure sensor and the injectors for contact resistance and oxidation
5Have a workshop with diagnostic equipment check the injection pump and the fuel pressure
