Hi, I posted a message on the general site and nobody came back with a suggestion. Maybe the T5 owners might be able to help. I have a 2003 S60 T5 in pristine condition with 70,000 miles on the clock. In the last week I am getting a hissing noise when I press the brake pedal or let it go, like wise when I let go the accelerator? There is no difference in the braking, it still performs 100% as new. Please somebody tell me it isn't a knackered brake servo? I believe it is savage expensive to replace. I've had a grin on me since I bought the car, but it will disappear very quickly if this is true.
