Hi, I have an Cooper S R56 N18 (2013) with Manic Stage 1, and I have this awful sound that it does sometimes after doing some driving (never with a cold engine), it only sound if the car is not moving, if I press the throttle it stops until I release it.

Anyone have ever hear something like this before?

 

Could be numerous things, resetting the vanos adaptation, throttle body, or even fuel. Perhaps the tuning did not have all the values entered. take it back to the shop for them to take care of it?
