Hi guys, new here.
I acquired a FL1 TD4 back in 2018 .. 41k miles.
It was all original.
Still AWD, and apart from a few perished bushings, tyres, and rear silencer, didn't need anything else doing.
I regularly swap wheels front to back, to keep the larger diameter tyres on the front, so still on original Viscous Coupling.
I replaced the lift pump around 100k, with filter. Recon Injectors at 140k.
Currently 200k, but has started throwing up a fuel pressure code ... P0190, but only after engine gets hot. I can drive 20 miles or so before it slips into limp mode.
When the engine is hot, if I stop the engine, with just the ignition on, I cannot clear the code with my basic tester. Once it has cooled sufficiently, the code can be cleared, and I can drive normally until it gets hot again. This feels like an ECU issue .... Does anybody have any thoughts?
Leakback test shows slightly worn injectors but increased leak on 1 and 4 when hot... I have stripped them down and ultrasonic cleaned them, they show good mist pattern.
Awaiting set of 4 recon injectors
I have replaced lift pump and filter as it was starting to get noisy, HP pump with regulator, checked all harnesses, replaced fuel pressure sensor(Bosch) and fitted the upgraded harness.
I've found a few older posts with P0190 issues, showing several different resolutions.
If anyone has any ideas, I'd be most grateful.
