I have a 3 year old 225xe. It’s a lovely car but I have a repeated drivetrain error fault occur when the battery runs out of juice. BMW have had it back about 5 times; have reprogrammed it, replace high voltage cable and various exhaust manifold thingys which does not I’m my mind have anything to do with the problem. When the problem occurs the engine takes over and it refuses to charge. Engine also ‘hunts’ whilst idling. Quite often if I turn it off for 1/4 hour it’s fine. I reckon the batteries overheat but bmw say their tests show batteries are fine - but they would wouldn’t they!
Does anybody else suffer from this and does anybody have any ideas.
Thankyou.
