    gettin desperate for some help here so I thought I'd start a new thread so as many see this as possible...
    Havin trouble with a no start on the car posted here http://www.audi-sport.net/vb/a4-s4-forum-b5-chassis/110902-help-needed-engine-wont-run.html

    What I want to knopw is how does the ecu get its power supply, is it through a relay? If so can someone give me the location of it and the number on the top of it or whatever
    Many thanks for any info

    ECU gets an unfused permenant feed directly from the central electrics panel.

    Then a fused switched live, from fuse number S232.

    Ok thanks aragorn. I wasa hoping you were going to say its supply comes through a relay coz that would have been something else to look at. Cheers for the info though anyway.
