Hi i've recently fitted a recon Bosch pump to my 2.5di . Ever since I've put the new pump on there's a lot of black smoke when you put your foot down , overall engine noise has increased from before the pump change and its using more diesel.
Been told the pumps over-fuelling, can anyone point me in the right direction on which screw(s) to adjust on the pump ? . Or any other ideas on why the engine noise has picked up etc , Many thanks in advance
