I have a F15 with only 35k miles on the clock. Since June this year, the engine starts making clicking noise and excess vibration at idle compared to what it had. The noise is coming out from the right hand side of engine as you can hear/see from the video.
I have checked a number of times with ista but with no error code. The car drives perfectly fine but just this noise and vibration bother me a lot.
