I've purchased 06 r52 mini cooper s convertible yesterday and had pre purchase inspection from miniworx at southbay and they said this is normal since it's supercharger engine. I used to drive r56 mini cooper base model but i haven't seen this rpm needle moves up and down before even though car is parked. Is this really normal?

 

looks normal to me...needle didn't really move that much

 

Both my 2004 Cooper and 2005 Cooper S do this. Have owned the 2004 since 2004. Owned the 2005 since 2007. Both have done this since new. I would say normal.

 

Looks like it could just be noise on the signal to the tach. I wouldn't worry about it unless the engine RPMs really start jumping all over the place.

 

Mine does the same.

 

Maybe you have a racing cam!

jk, totally normal.

Thank you guys!!

 

Yes, my R52 does this also. Just bearly moves up and down.
