    Car wont start, faulty ECU, how much should it cost? 16th Apr 18 at 5:12 PM
    My car just passed mot last month, no problems at all.

    Then one morning it wouldn't start.

    Called the breakdown, he couldn't start it either. So towed me to the official Vauxhall garage.

    They plug the computer in and it it doesn't say anything is wrong.

    They still have it, and after hours of trying to start it they can't start it either.

    What is the next step?
    Nothing has been fixed since 2008, it was just pushed into the future

    Assuming your car is a Vauxhall then you have already taken it to the 'experts'. Your only other option would be a good auto-electrician. ECU from main dealer will be £££'s with programming and messing around. You can get them repaired but first someone has to confirm that the ecu is faulty and it is not something else that is the problem like the crank sensor; they often don't generate fault codes but you won't get started if has gone.

    Repairs are around £150-£250 typically. Quite a few companies doing it, can recommend The ECU Doctor in Plymouth.

    Had this once where it turned out to be dirt on the crankshaft position sensor. It wasn't picked up by one diagnostic kit but was by another.

    Hi I get loads of these, Vauxhall ECU problems,
    First how old is the car?
    Engine size?
    Petrol or Diesel?
    Was there any other problems before,
    IE: misfire, Steering problems, Hard to start but did start, engine warning light on?
    These are important questions and need to answered Truthfully,
    as I have had customers say no to the above and it only takes longer to Diagnose

    My Megane has a fault on the ECU causing the hazards to come on, I will be interested to know the cost too.
    When we are talking about a new ECU, do we mean a reboot and reprogram?

    I had a problem last year on one of our cars that sounded like stuck/sticking hydraulic tappets but there were no error codes showing. Finally took it a specialist and again there were no error codes but their reaction was: "If there are no error codes then it has to be something simple" and it was - 2 loose spark plugs!!!!

    Hopefully yours might turn out to be something simple - broken earth lead, or similar?

    Spare key
    You haven't just started to use the spare key have you.
    Friend of mine mislaid his key, so they tried to use the spare key that his wife always carried in her handbag, never used for ages (years). Car wouldn't start, AA out to it, taken to a reputable garage with diagnosticequipment, still wouldn't start.Just about given up on it!
    The original key turned up and for some reason, probably desperation they tried it, car started right away.
    Apparently for some reason the spare key had either lost it's programing or become corrupt.
    Never heard of this before, but it did happen
    The other side of the coin, if you have a spare key have you tried it??

    Good luck and let us know the outcome

    normally code P1614,
    The key is made into two parts the remote, and transponder to start the car.
    again need to know age as cim module is common on these

    Until the OP comes back and answers the very first question that they were asked everybody is wasting their time in this thread - and the OP's recent posting record would suggest that might well be the case even if they do answer the question.
