Increased consumption after replacing injectors

Recommended Posts

Hi, everyone!

I experienced some issues in the last few months with my 520d e60 from 2007, engine code N47D20A.

I changed the high and low pressure fuel pumps, injectors, fuel pressure sensor from the fuel rail and few ofher things.

All my old injectors were busted after the high pressure fuel pump decided to die unexpectedly, pushing loads of debris in the injectors.

After replacing all the 4 injectors with some used ones, I experience a high increase on the consumption (from 5.7-5.8 l/100km to 12-14 l/100 km). On top of that, the engine is vibrating much more than usual and the power appeared to be decreased.

Any ideas?
