Hi Trudy

Welcome to the Forum

You need codes read to be certain what the issue is or even if you have an issue at all.

I have read that a simple reset often cures the problem. Turn off, remove key leave 5 or 10 mins restart and see what happens. Or disconnect the battery for a while that resets stuff also.

If the fault persists you really need the codes read to have a chance of diagnosing the problem, a BMW dealer will be the most expensive, a BMW Specialist would be better or a good Independent Garage with something like Autologic will be able to run a diagnostic check if the fault returns.

Good luck

Dave
