Well... The gremlins have showed up again, engine cut out again when trying to join a motorway. Popped it on PP2000, when the engine cut out, the pressure recorded was only 933 bar, the max pressure is slowly decreasing over time.
On idle, Fuel rail pressure is recorded around 298 bar +/- 10bar. If I quickly rev it while the car is stationary, I will never see 1300 bar, max I've seen is ~850 bar.
I've done an injector leak off test (using a Renault leak off test kit) at 5 minutes on idle (from cold) the results were:
Inj 1: 26ml
Inj 2: 36ml
Inj 3: 36ml
Inj 4: 35ml
I did do an injector leak off test when the injectors were installed around 180k (now on 230k), and Inj 1 was always lower. Using the same kit, My friend's HDi got 32, 25, 45, 50 in half the time.
Is the HP pump due a replacement?
