I posted a few weeks ago about a lumpy idle issue on my XE 240d, most answers suggested the engine mounts. Dealer found nothing wrong, not suprised as it was intermittent 🤷♂️ Since then the idle issue has developed into the car stalling. When I pull up the car sometimes feels fine, other times feels rough and lumpy while idling. When I release the brake and go to accelerate it's stalling on a semi regular basis?? I manged to catch it once and flick it into neutral while left foot braking and when I tried to rev the engine, it wouldn't rev?? Even foot to the floor it wouldn't rev just chugged at 500rpm or so then died again?? Only light that comes on is battery light??
