Vibrations and shaking in F20 LCI, 120i, B48

Hello,

For some time now, when I stand and wait at traffic lights while the car is in neutral gear, vibrations and tremors are felt throughout the passenger compartment. They happen every 10-15 seconds and are not very long lasting. When the car is in motion there are no problems. No other issues (noises, rattles, loss of power).

I had some rough idling at about 45000 km. Changing ignition plugs fixed it. And by the way, reportedly, bad plugs can kill ignition coils.

If they aren't old, you can actually just have them inspected: if they look fine, that's all right then. If the issue persists, have some diagnostics, perhaps. Also try to search (if you haven't already) whether anyone had similar symptoms and solved it. For something like this: https://f20.1addicts.com/forums/show...6&postcount=42.
