2.5 v6 tdi fuelling issues


New Member
Hi everyone

I'm looking to get some help or advice. I have an a4 2.5 v6 tdi quattro so basically the camshaft pulley shattered causing valve and piston damage. I then replaced the engine with one of identical code (AKE) keeping the original fuel pump, injectors, alternator ect a new timing belt kit and water pump was fitted. The car is in limp mode iv tried replacing injectors but lights still on.


00542 - needle lift sensor (G80)
Open or short to plus
00550 - start of injection regulation

Could this be a fuel pump issue???
