Super Charger Bypass on but not operating

[BryceKat]

Hi guys, my 2000 c230 k has a bypass valve that is getting power/signal but is not closing when the sc kicks in at 2k rpm. No cel on. Any ideas on what to do? Thanks Brycekat

Try a full throttle blip.

you can vent it to atmosphere for test or just leave it like that for bov noise but pop hood on drivers side (usa ) for me the throttle lever is there quick hard blip and you should hear it minding supercharger wont kick in until 1900 rpm on facelift version
