Hi all,
I had much car serviced today and the technician (a good mate of mine and an Audi trained tech) - noticed the vacuum pipe for the exhaust valve had been disconnected and 'bunged' with a screw, this left the valve in the close position. As the valve can be opened / closed he removed the screw and fitted a new piece of vacuum hose.
From what he said and from other posts I've read, the valve allows to car to be quieter a low rpm then open up as you put your foot down thus making a bit more noise ....... so with it reconnected I took the S3 for a blast but didn't really notice much difference?!?
With the car stationary I put my iPhone in video mode under the rear box and filmed the valve as I rev'd the engine - nothing happened!
Is this because revving the engine does not 'create' the same driving effect that would normally operate the valve or is something knackered? How could I test it / prove it's now working?
Thanks
