Hi gents ,

I've purchased recently a R53 JCW ( 2006 Park Lane edition with RECARO seats and OEM LSD ) at 172.000 km .
It is my 3d JCW ( my 4th R53 in total ) and I find the supercharger whistling much more compared to my others R53.
It's nice to hear , but maybe it is hiding something bad on the engine.
When accelerating , the power of the engine seems similar to my other JCW .

I'm wondering if it is a clue of the supercharger " swan song " , if it is coming from a leak on the inlet ducts , etc ....

In a few words , is it normal that some supercharger are more whisling than others ?
FYI , my other JCW and R53 have lower mileage : 118.000 , 112.000 , 152.000 km.
This last one ( the JCW Park Lane ) is 172.000 km .

You will tell me : open the supercharger and check the oil and the bearings . OK , fine . But is there something to do before , to check easily the " health " of the supercharger or an air leak somewhere ?

Thanks for your advices .
