Vibration at idle

[atte_F82]

I have a stock F82 2016, 34 miles. I can feel vibration in the seat when the car is at idle. If I put my hand on top of the cooler, that's where I can feel it the most. The car will go for crank hub fix in a week, but wanted ask if anyone else had this vibration issue. Would highly appreciate all the help. Thank you.

Check your plugs. I had one seemingly good plug that had a small crack in the ceramic near the ground strap. My car ran terrible at startup until I swapped it out. Other plugs were clean and white but one was dark and showed residue. The darkness and residue keyed me in to a deeper look, and a strong flashlight showed me the crack. The spark was short-pathing up in the plug collar.

There were no codes. TMIC shaking showed me the engine vibration.

Once I swapped that plug out she went back to purring like a kitten.

Thanks for the tip. The car is currently in for CB fix, we will also change the plugs etc.

Bump for update?

Did changing out the spark plug fix your issues? I'm also experiencing excessive vibrations in my seat and on the 6MT shifter. Vibrations also coming from the Top mounted intercooler.

Really interested in your results.

Car has only a little vibration after service. Runs great now

I have noticed a good amount of vibration lately or perhaps it's just hypersensitivity. It only happens when the car is in Sport + and the AC is on. I assume that's just a lot of things happening with the extra drag from the pulley and the fan at full speed. Is a bit of vibration normal? Thinking about it now I don't think I've ever had the car in S+ mode with the AC on before recently so maybe it's just something I overlooked.
