This car has now become an absolute nightmare and is close to pushing me into unmanageable debt.
First the electrical steering rack failed. Breakdown recovery wanted the name of a garage. Nearest dealerships couldn't take it for a over a week so went with a local BMW specialist. £2700. Contacted BMW to see if they could help with goodwill and they refused, saying it would need to be seen by a dealership and it would then be at the discretion of the dealership, but from my description it would be very unlikely that they could help. So my options were either to pay hundreds to get it towed to a dealership who would probably refuse to have it fixed under goodwill, or suck it up and get it fixed locally. I went with the second option, hoping to chalk it up to bad luck.
A month later the engine warning light started flashing and the car started misfiring. Local specialist advises replacement of all coils and plugs at a cost of nearly £600. A week later the EWL comes on again. This time it's injector #1, which needs to be replaced at a cost of nearly £500, with the garage saying if there were any other problems all the injectors would need to be replaced at a total cost of @£1500. Currently still in the garage as despite replacing the injector it's still misfiring.
Total repair costs, assuming the inevitable and all the injectors will need to be replaced, will be @£4,800. I wish I had seen this thread before buying a car that has used all of my family's savings and more.

Sorry to hear of your experience. I can't offer any solution as I sold my E91 without ever getting to the bottom of the issue. However, £500 for a single injector seems a little steep to me? I recall a mobile BMW technician replacing one on my drive and it can't have taken him more than 15 minutes, if that.
I am shocked to read all these years later that there doesn't appear to be a definitive fix for the N43 problems, let alone any suggestion as to what the root cause is? The standard suggestion seems to be "replace all the coils and injectors with new" just for the problem to return again?
