When I press the gas pedal hard theres a shaking and vibration I feel through the whole car but its only when I gun it. If I gradually accelerate it doesnt happen. Can anyone tell me what this is? 2008 528xi 53, 000 miles.
See my post regarding Sea Foam. The back side of your intake valves are probably getting carboned up. I think it blocks off the air and makes that cylinder(s) run rich.
I was having the same issue with mine and I also thought it was the tranny, but i did get a CEL on when this happen. it ended up being an ignition coil. (this happen last week) changed coil and is back to normal.
I know its late but just to update, nasty u were right needed to replace an ignition coil and all spark plugs due to an oil leak a while back. Thanks for the input.
