  1. Welcome..

    I would like to send Marelli 4LV ECU for repair.. from Hungary..

    Problems:

    After 10 minutes of driving… it starts to accelerate more… or it doesn’t
    respond to acceleration… or sometimes it even shuts down… P1553 or P1504 error
    occurs… vacuum sensor and air leakage…

    When going uphill, he simply took the control off the throttle… (measurement:
    voltage disappears) I could only go up the hill at 1200 rpm…..

    .. crashes when accelerating… or sometimes chokes… stops … Can be restarted
    later..

    There are also false error codes:

    P1553 , P1504 ETC

    lambda probe heating fault (no break in the heating filament) output can be
    measured

    brake switch error… (good, the switch is also set… supply voltage can be
    measured…)

    Sometimes the immo won’t let you start…( Ecu locked )

    long-term mixture adjustment 40-50 % shifted… it’s been there for years… for
    no reason…
    Not now..

    There is a problem on the logical side..?? I mean processor or its environment..

    The car wreckers are running out of these ECUs.. there are hardly any left…
