I’m wondering if someone can help me I have a 1 series F20 model with 30K on the clock, on rare occasions for example just popping into the shop for 20 mins or so then going to start the car the engine will cut out instantly….within 2/3 seconds it’s dead….I will then start the car again and it’s absolutely perfect this never happens on cold starts, no warning lights on the dash or idrive, I’ve tried different fuels but that doesn’t resolve anything the bmw garage scanned the car and no codes were found, any advice would be appreciated thanks!
