Hi, I'm a noob with a problem!
I recently purchased an M reg GS300 Mk1 Automatic, which I'm loving, all except a couple of minor issues.
I noticed a hissing sound which I thought at first was the fan, but having listened a little closer it is definitely coming from elsewhere.
The hissing only occurs when the car is accelerating, and goes when the brakes are applied. I thought at first it may be a slow puncture, and my suspiscion was strenthened after testing the brakes at above 60mph- the front passenger wheel appeared to 'wobble'.
Since then I've checked the pressure of all the tyres- all at 28PSI, and the air pressure machine does not indicate a puncture.
Anyone have any ideas? I suppose it could be a wheel bearing or brake piston which I haven't checked yet- if so that would leave the hissing sound which is starting to concern me......Any ideas anyone?!
Thanks
Shaun
