my Octy VRS has had a forge adjustable dump valve fitted for ages, before i actually bought it and works well, all of a sudden it's stopped dumping, the engine now sounds a little muffled, still running smooth but worried there's a big problem, i'm not an under the bonnet type of guy unfortunatley and when i've looked for the dump valve i can't even see it!! any ideas and where the chuff is the dump valve!!

Cheers in advance guys and gals!!

Its more accessable and viewable from underneath mate.Take off the under tray then look up at the rear of the engine its by the turbo.

The solenoid to actuate the valve is usually mounted top-front on the engine mate.
