    Low Pressure Fuel Pump Faulty?

    Following on from my other thread:
    http://www.aulro.com/afvb/d3-d4-rrs/...ml#post2327647

    I was reading this post:
    DISCO3.CO.UK - View topic - Acceleration Fault

    When I did the test myself the pump is pulling just over 4A. Could a failing/faulty low pressure pump cause me to get special programs disabled and limp mode under medium or harsh acceleration?

    It could be the low pressure fuel pump - but sorry to be the bearer of sad tidings - it is more likely to be the high pressure fuel pump.

    Update:
    I was made redundant on May 28th so paying for the HPFP was not an option.
    I noticed the fuse for LPFP was also melting. It turns out I had a bad contact in the fuse, it wasn't priming upon turning the key but if I gently pulled back on the fuse all was good. It has had a tie wrap pulling the fuse back for some months now and the issue has not returned. Fixed? Maybe!
    I also add 300ml of 2 stroke oil to every tank of diesel now
