    Default How ******** Much!!!!!!!!!!!

    Just got my car back from the local dealers after they have diagnosed my cutting out problem.

    The ECU was shutting down the engine due to low fuel pressure caused by a faulty diesel fuel pump. Seems logical to me, so they are ordering me a nice shiney brand new pump ready to be fitted on monday

    Anyone want to play "Guess the price"????????











    When they told me the price i nearly fell through the floor

    £1660 for the pump and £93 for a new fuel filter and a few other bits and bobs. Thats just for the parts! Thank the lord it's under warranty.
    How that price can be justified is a mystery but i'm glad it's gone now and not next year

    very true Tony, had it gone next year i think you'd have left the dealership crying!!

    that is one hell of a price tag for a fuel pump!!

    when they said "faulty" did they go into any further detail i.e. did they say that it had worn prematurely?? I'm just asking as the inevitable "do you think its becuase of the performance box" question will pop up.

    oh yeah almost forgot.....do you think that its because of the performance box that the fuel pump went belly up!??!

    That is one helluva price tag for a fuel pump!!! Is that 'cos it's a diesel pump, or is the petrol one going to be as equally wallet busting?

    They did not know any details and did not even take it apart. They plugged good old Tech2 in and read the codes. Apparently they did not know what the error code was so had to contact someone else. They then told the dealers to order a fuel pump!
    I only hope the don't rely on Tech2 to replace it for them as well Looks like the properly qualified mechanics of old are thin on the ground nowadays.

    I don't know whether the tuning box has had anything to do with the pump failing but i think it has highlighted the problem moreso as thinking about it logically, if the tuning box is asking for more fuel to be put into the common rail the pump obviously needs to work a bit harder. If the pump cannot cope with the demands then the rail is not going to have the required pressure that the ecu wants. It will then detect that the pressure within the rail is low and shut down. I think

    Jeez, they are expensive

    I doubt if the box is anything to do with it though, correct me but it doesn't put the pump under significant extra load does it?

    It exerts more load on the injectors I thought.

    I've never heard of a pump going before.

    I can see the worry though, there seem to be a few boxed vecs throwing up various problems.

    As you say Tony, thank god it was in warranty.

    Hope they sort it mate.

    Hmmmmm, wonder if that was the problem with my car pre turbo blow up?
    Seems likely to me.

    I used to manufacture diesel pumps and I can confirm that they are firkin expensive to replace. Engine makers get them at reasonable cost due to bulk buying. Motor factors and dealers that wanted replacements would have to pay through the nose for replacements, though thankfully they are that robust it is VERY rare for the pump to fail, at least with ours we once had a pump from a 30 year old Land Rover that was having an engine refurb, they sent the pump back to us to be checked over, I slapped it on a test rig and it was showing better tolerances than a lot of our new ones! It was stripped, cleaned and sent back with no charge as we were so chuffed.

    Anyhow, I suspect that if the pump is being asked to work a lot harder than it was designed to by a tuning box, then I would expect it's life-span to be reduced, as with any device that's asked to exceed it's design limits.
