    Pre fuel pressure circuit fault, anyone have experience?

    Thanks eightinavee, a very comprehensive and educated response, I will ask on Monday what type of diagnostic equipment they are using and ask the questions you have asked relating to live pressure monitoring, I did wonder how they could measure fuel pressure on both the LP and HP sides of the...

    Pre fuel pressure circuit fault, anyone have experience?

    in all fairness nobody on the forums has been able to give any further advice as to what a diagnostic result of "pre fuel pressure circuit" fault might be, so cant exactly say the mechanic isn't doing a good job. Latest update is that the advance pump and auxillary pump have both been changed...

    Pre fuel pressure circuit fault, anyone have experience?

    Hi sorry I forgot info, yes its a diesel, standard, no fuel modification. mechanic has still had no joy, they traced back the wiring loom to see if there was an issue with it but to no avail. I don't think he has even nailed it down to knowing whether it is a mechanical or an electrical fault

    Pre fuel pressure circuit fault, anyone have experience?

    so was it the in tank pump that went on yours? Seems strange it is pulling up this diagnostic fault if its a pump issue. Still think it may not actually be a pump issue? any method of checking pump pressure in the line?

    Pre fuel pressure circuit fault, anyone have experience?

    Hi Saint, its a valid point, the mechanic is struggling to know if the fault is mechanical or electrical from the diagnostic. Problem is that I have already spent £400 on parts and labour replacing the outside tank pump without any progression. So I am trying to keep cost down and was hoping...

    Hi All, got an issue which my local landrover specialist is stumped about, hoped someone might be able to help. Went out in the RR and the car went into limp mode, tried it couple more times out and whilst it might not go into limp mode from the word go, it does after half a mile or so. No...

    Help! L322 gearbox problem

    okay, so spoke to the garage today, turns out it is gauze and filter on the pre fuel pump that is blocked, it has worn out the secondary fuel pump due to this reason and it needs to be replaced. All said and done, not too bad really, oh, and they also sorted a tiny leak on the high pressure fuel...

    Help! L322 gearbox problem

    Anyone had this problem before? my inital thoughts of the fault are that my wife is a bugger for running it around on vapours and my thoughts are that it could have pulled a load of crap from the tank into the diesel delivery line.

    Help! L322 gearbox problem

    Hi, heard back from the garage, diagnostic fault was a "pre fuel circuit" fault, nothing to do with gearbox fault. Spoke to the mechanic and he explained a bit about the fuel system on the car. Can someone confirm this is correct, there are 3 fuel pumps, 1 in the tank, 1 outside the tank, and...

    Help! L322 gearbox problem

    Thanks Saint for your detailed explanation, so, I have just taken the car to the garage this morning, and I was incorrect in saying that the gear was stuck in 1st, it appears that the car changes gear fine, but it will not go above 40 mph, flicked into manual and it goes through the gear changes...

    Hi All, My 2004 L322 TD6 with 70K on it has just developed a gearbox problem, it started yesterday, when driving in town at low speed in automatic, I tried to depress the throttle to accelerate and it would not speed up past 3000rpm in the same gear, stayed like it for a mile or so with the...
