That’s it nothing happened it still drives. The BMW Tec came out this morning had a quick look then said it’s got to go in. I took it, with him following me, got to the dealership they said not seen this before so it’s got to have a full diagnosis to see what the problem is. I think it may have something to do with the Mild Hybrid second battery and generator. I will let you know when I get it back -

BST cable wiring diagram e93
Morning Mo Welcome to the Forum That looks like the MRS cable so getting something wrong could fire Seat belt tensioners or Air bags or it could be the IBS trigger lead My instinct here is change the cable to avoid issues you will probably have the airbag lights to reset as its been disconnected. Do you have access to INPA/ISTA you may find wiring diagrams there. Check realoem if you haven't already to see if you can get part numbers that may help I have changed the complete main battery lead on a 1 series where the IBS had been triggered and fired the tensioners but fortunately no airbags so didn't need diagrams just replce parts and reset with INPA Dave
