    mot tomorrow and faults today

    Typical, MOT tomorrow and the car has faulted. Coming up with blind spot monitor failure. Switched off and on and it's still there. So put the diagnostics on and got the following.

    state intermittent front left- side marker lamp - signal stuck high. This cleared.

    State permanent Control module calibration data #2 - missing calibration, This wouldn't clear.

    State permanent High speed can communication bus - invalid serial data received, cleared

    State permanent Control module - internal electronic failure, this wouldn't clear.

    I run the diagnostics while on the supermarket car park. Switched off and went into the shop. When i came out blind spot monitor was working, and car ran perfect.
    So am i in for a big bill in the near future?
    What can be the cause for all these, or is it just a glitch ?

    Thanks for any input
