    Maybe a bad camshaft sensor? Maybe the timing chain somehow skipped a tooth? It sounds like something that a professional should check out.

    Before you go any further, see if you can double check the actual code that was stored (Pxxxx) just to make sure that the auto parts guy referenced the right codes for our cars.
    Tell us what it is.

    Try clearing the code and see if it comes back, if it doesn't, great, that is the best result, it was a transitory problem.

    There could be a problem with the VANOS, which adjusts the cam timing for different conditions. The Engine Control Unit is telling the VANOS where to position the camshaft and it isn't doing it. If the code comes back, then you should take it to a MINI technician for further diagnostics. An Independent shop will probably be cheaper.
