I know this has been dealt with a lot but my 2019 M240i stop start only works when the car is on eco mode and a/c off.

It recently had a major dealer service and no issues were reported like low battery etc.

Is there anything I'm missing or is this normal procedure?

Thanks

Hi Dave

Sounds weird couple of questions (1) Was it like that before service ? (2) Did you ask the Dealer to investigate as many Dealers only use the Diagnostics if there is an issue

I thought Auto Start/Stop was either On or Off ? Maybe a conversation with the Dealer to find out just what they did and whether there was a Diagnostic run

I didn't mention it tbh as thought of a new battery on top of a major service bill wasn't appealing.

I generally just run the car on eco locally but am confused if the stop start works on any other drive setting??

Today it decided not to work at all during a 100 mile round trip.

No warning lights or anything.

I think I can live with it for now tbh, more irritating than anything.

Thanks tho
