The good news (if you can call it that) is that it was a simple <30min £60 job for BMW to recode the part of the ECU to recognise the keys again. The BMW techie I spoke to diagnosed the problem following my description before he'd even used the fault diagnosis stuff, so I guess it's not completely rare if he'd seen it before.
Seems like madness for flattening a battery though.
You dealer has been really nice.
I have seen this many times when people take their cars to dealer and straight away
£90 for diagnosis only and rest of bill settles later.
Ally, in your case immobiliser was stopping it to start due to multiple tries.
If it was a yellow steering wheel, then it is more or less registering new battery and resetting errors.
However in this case it is red steering wheel failure.
To keep things simple, I would still take the same approach but in worst case, updating the module should resolve the issue.
NJ 1161, ring your dealer and see if they can resolve for £60 and TBH it is very reasonable price.
However if they give you £90 diagnosis shit, stay away from them for the time being.
