    "Now I'm at a loss of what to do next". Now you get a small pump and apply 1 psi (69 mbar) to the sensor inlets and watch the data. This will not only let us know if the engine management is seeing...

    But are they correct at the DPF? This is why I wanted to see the pressure under load 3000 rpm, the pre DPF pipe ( which from memory I think is the larger diameter pipe) should with a good DPF have...

    avisonjohn,
    Are you 100% sure the pipes are on the right connections? To check what the engine management is seeing, apply some low pressure to the pre DPF inlet on the sensor and see what the data...

    Now try it at 3000 rpm and then get someone to block the tail pipe at 3000 rpm and tell us what the pressure is.

    Hi Ben Pine,
    It means your AC compressor clutch is not powered, although without looking at a some tech info I am surprised it has a clutch and is not variable geometry. So look at your handbook and...

    Hi iichel,
    I would start with a "leak off " test on the injectors, to see if a faulty injector is causing the low pressure. Have you got a high pressure gauge to test the HP pump manually? Have a...

    Hi Uwe,
    There are circumstances (not necessarily this one) where a vacuum leak can cause a rich mixture. If a leak is close to a MAP sensor it can fool the system into thinking the engine is under...
