300 tdi problem

Hi Guy's

My 300 tdi is loosing power on the high end of each gear, it appears to be starving itself of diesel. I have replaced lift pump & filters. The fuel filter is not filling to the top. When you loosen the top nut there is no fuel coming out ! Does anyone have any ideas ? Cheers John.

Have a look in your sedimeter? If its filled with sludge its gonna restrict flow and recontaminate your filter

Air in system. Check round the sedimenter and look for diesel leak. Check fuel sender pipes under hatch in boot floor corrosion on the metal bends is common.
