I was reversing out of my garage today and received a malfunction notification on the idrive screen accompanied by the yellow cog.
The malfunction was:-
Limited gear selections possible.
Continued driving is possible.
Have the system checked.
I will ring BMW first thing this morning to get them to have a look at it.
Given that it's Friday and the car is not already booked in I am guessing that I am going to have to wait until next week sometime. Wish me luck!
