Ben shepherd 86 Posted July 1, 2022 Share Posted July 1, 2022 Just bought Audi s3 60plate. I have noticed the exhaust valve is normally open when parked, the solenoid and lever arm works manually by hand. Does anybody know if it should be normally open? And if so how do they work and when do they close? thanks for any replys Quote Link to comment Share on other sites More sharing options...
