Been chasing a problem for months and I think I may have the answer finally.
My fuel pressure from the tank dead headed is 3.5 to 4 psi using vag com in output mode to activate the pump.
I do have etka and it does not state anywhere what the fuel pressure should be, only that it can be tested electrically by plugging a test switch into the fuse location.
When I look for a replacement pump I get a choice of 0.5 bar or 5 bar.
The engine runs well untill I demand more fuel,
I have tested alot of components fitted a new turbo and actuator.
any help would be appreciated.
