Wonder if anyone has has this problem, I'm hearing a hissing noise from under the bonnet when I accelerate. I can hear the usual supercharger whine but then a hiss comes in. I've tried to make the noise when parked up and reving the engine but it only seems to happen then I'm driving. Sounds like a leak but I'm not sure if its some sort of release valve.
Remove the intercooler cover only 4 torx screws
Have a good look at the rubber intercooler boots, make shore there fitted properly and are not split. You can run the car as well see I you can here it hissing with the cover off.
Do the brakes feel ok ?
Also check your spark plugs they have Tendency to come undone, so while your there always worth checking
Ah right, as far as I can tell they are fine. Think I'm going to have to take it somewhere to get checked out. Last thing I want is the supercharger going or something like that. Anyone recommend a mini specialist or decent place to go in the Newcastle area?
