What makes you think it's the alternator? Faults with those is pretty rare in modern BMWs, it's usually a dying battery, or the battery has been changed without the systems being taught there's a new battery on the car.
If you're seeing a steady 13.8 to 14.4V DC at the jump start point with the engine running at fast idle there's not much wrong with the alternator.

You don't say how many miles it's covered but I have just put an alternator in our petrol focus at 53k ! ,but it's doing all stop / go very short ( 2 mile) journeys so is always flat out charging , car is 11 years old now and age plays a part too 
They often make a whining noise too when they are kaput

Nothing specifically that it's the alternator other than I being part of the charging system and is something to look at, I plan to get out with it at the weekend but was just looking to do some preparation reading.X5Sport wrote: ↑Fri Feb 11, 2022 1:51 pm What makes you think it's the alternator?
