HI
I have a customer with 1.4TSI Tiguan. He has previosly replaced HPFP cause, it makes loud clicking noise. He thought failure of pump. He replaced it, but still the noise and High Pressure fault. Then he came to me. I made autoscan and read SSP.
The High pressure sometimes while working drops(looking at MVB) and the clicking noise

I myself am blaiming the Lift Pump module. Am i in the right track or should i test something more? I looked at adaption and basic settings in VCDS, but didn't notice anything.

I think you should check oil psi during noise....and measure camshaft endplay lobe run out and see if the roller tappet is damaged.

Fuel pump plunger has also been replaced.


Can you explain me Yout hought of how does oil pressure alter fuel pressure as the noise is clear indicator of high fuel pressure measured at the same time with VCDS.

Because oil PSI dictates a tolerance in the head cam journals, and when expanded under heat conditions or friction requirements are widened due to duty cycle .......heat grows and oil PSI falls which can create chatter resonance for sound which can travel.

This chatter increases heat and accelerates pump/lifter/cam lobe failure........and vicariously injectors.

Why do you think HPP pumps fail and parts plug the injectors long after a filter process because there is no filter after the HPP........

Same can be observed in TDI HPP pumps.........

Sounds like you have a wiring issue there for the HPP to be open circuit and all the rest cam sensor etc. They do get a bit tight round there.

Hey I think that might help but also seems like a vapor lock issue too but isn't going to help for the oil being diluted with gasoline further damaging the cam adjuster/chain issue causing the cam/crank correlation DTC.

Ended up being chain issue after all.

After new chain and CORRECT TIMING(2 jumped teeth) no more fuel pressure issue.
ECU also updated.
