I tried the same thing today and it does buzz continuously right until I start the car and my RPM relay *does* work, so what's causing this? My main concern is if this can be dangerous in any way and how it can be sorted out. I haven't look at the earth strap as Kevin suggested though... Yet again - are you guys sure it is the frequency valve? When I first heard the buzz, I immediately thought of the coil, but no sound there/no sound on the right hand of the engine compartment. I'm positive that this sound comes from somewhere around the cold start valve - are there any other "gadget" around that area which could cause the buzz. Again - is the buzzing dangerous in any way? It does sound like the whole engine has gone electric!
