Hi all,
I am coming to you desperate, my MK5 was new to me in June and ever since I have been chasing low fuel pressure. I hate to think it may be the cam, especially after inspecting it and visually it felt okay, with very light scoring.
I have replaced the following in this order:
In tank fuel pump
Fuel filter
Cam follower which was worn a lot but not all the way through
Fuel pressure sensor both on the rail and hpfp
High pressure fuel pump
Fuel rail pressure release valve
I am still getting the following codes, low power and low fuel pressure at wide open throttle after 3k rpm. Drops to about 60psi
System too lean at idle bank 1 - No signal/communication P2187
Fuel rail/system pressure too low - lower limit not reached P0087
I am at a loss and not willing to accept it is the cam yet, please help me😂
Could there be any other possible solution? No smells of petrol indicating injectors leaking or anything
