    I've had my E46 2001/Y 320i SE for just over a month now and I'm considering taking the car to a BMW dealer to have to Engine Management System checked out. There's no problems with the car and the EML light is not on. This would purely be as a service/check to see if it's standard and has no stored fault codes etc. I'm asking for advice to see if it's worth getting the ECU checked before I shell out the money. Does anyone have regular checks done on their own car and find it worth it? Do BMW have 'software updates' for older BMW's which are installed whilst on the diagnostics? Any advice or answers would be greatly appreciated.

    Personally I would save your money. The BMW obd stores up to 30 (or 32) instances of any individual fault.
    When my car alarm went whappy as the sunny weather arrived, it was showing the maximum number of faults on the bonnet due to the dodgy switch, with numerous other occasions where the alarm had activated from inside (caused most likely by the windows being left open and the internal sensors left active).

    If you are not having any problems, then let it lie. I am sure there will be an occasion where you will NEED to have the diagnostics done, and I would think then was a better time to clear any registered codes rather than outlay cash now.

    All that said, If you really need peace of mind and need to know if there have been any hiccups, then by all means go for it.

    It all depends how much you need to know.

    Sometimes a fault code can be stored for the engine but unless it badly effects the emissions it won't be flagged up, also getting the codes read can be a good indication of a problem that has occurred a few times but is likely to rear its ugly head in the future.(like a crank sensor problem or cam sensor for example)
