    DV symptoms are low boost but not an air leak you could have a split pipe its either gona be check them all or have a preasure or smoke test to find the leak

    Cheers bez Not having any problems with car it Runing fine just the light on the dash is doing my head in and i will get it pluged in again and right down the codes. The car has never felt quick to me that why I thought it mite be the dv or it mite just be a used to the pull of the old 5 pot 20v turbo engine.
