P2 code on my 2011 E350
What causes the P0002 code?
The fuel volume regulator range/performance code may have several causes:
Disconnected plug to the fuel regulator
Possible corrosion in the sensor connector
Damage to the sensor wiring to the ECM
Leaking or defective fuel pressure regulator
Damaged fuel pump
The ECM is damaged

click on the specific code and you'll get more information.
Again, these are generic codes and there is no rule Mercedes has to follow them.
Good luck.
