super-amg

when I turn the car in the morning, I hear a noise seems to be the supercharger, but when I use it, the noise disappears, it could be the supercharger oil, or a belt?

its only when the car off all night , and i turn on in the morning , thanks

hmm.. maybe i have the same issue. its happened maybe 4 times this past winter. i'll start the car in the morning and the supercharger is engaged for maybe a second and cuts back off. not sure why.

The supercharger is not engaged until the car gets to about 1800RPM with a certain load and throttle open %. You should check your SC pulley bearing.

i know my bearing may be going bad, and when coming to a stop with it engaged it does a little fluttering/bird noise. i have a new one waiting to go on that i've had for years. however, that initial supercharger cut in is the same exact noise it made upon start up for 1~ second. maybe SC clutch?

hopefully i'm not thread jacking here
