Hi there,
New to the forums so apologies if this is in the wrong place. I have a 2017 F20 M140i which is tuned to around 480hp and 680nm, i have developed almost a flat tyre feeling under acceleration, i have changed the rear tyres and alloys for my stock alloys which are fine and the issue is still there. Have noticed a slight hesitation under low RPM where i can feel the car almost misfiring but checked on ISTA+ and no misfires and spark plugs were serviced a few hundred miles ago. Took it to my friend who has worked on BMWs and is well clued up compared to me, he said it could be the centre propshaft bearing and the rubber donut which connects from the prop to the rear diff. Has anyone experienced anything like this before? - Driveshafts look OK, would the centre prop and donut cause this behaviour? Many thanks. ![]() |
