NeilGTi85 5 Posted November 23, 2007 Hello people, Recently brought a 1985 205 GTI and when i start her up there is a hiss (air leaking), when i press the brake down it goes. Onced warmed up though ( about 30mins) it does not do it? Any idea's? Cheers Neil Share this post Link to post Share on other sites
Grim.Badger 15 Posted November 23, 2007 I suppose it could be a small leak in the servo system; check the pipe running from the inlet manifold to the servo and the servo itself for leaks. Share this post Link to post Share on other sites
