Hi Team,
Does anyone know what's the expected pressure to deliver fuel from the high-pressure pump to the rail/injectors at cranking for this Audi A6 C6 3.0 Litre V6 TDI engine? Also is it possible to identify any issues in the wiring between the ECM and the injectors?
I have an Audi A6 C6 '08 3.0 litre Quattro which has been lying in the backyard unattended or never started for the past two years. Recently we thought of starting the car. As part of this, the high-pressure pump & injectors were professionally cleaned & fixed. Now while cranking, getting around 24-25 bar pressure in the high-pressure pump, but injectors are not opening, or fuel is not flowing to the cylinders. There are no fault codes while scanning. The battery is also new.
The lift pump is also in perfect condition, the fuel is reaching injectors, but injectors are not opening up to cylinder for fuel.
We even switched the ECM from a similar configuration running car, reprogrammed the immobilizer and still no luck
Thanks
