Just noticed the engine management light has just come on but car drives the same. Think I can hear a weird whistle noise ???? going into the garage on Monday.

Rich has just got one and I am waiting on mine to be delivered.

On the rear of the exhaust? A standard one? Because I have a milltek cat back so I don't have a flapper. I have a standard cat, I have never herd this noise before so it must be a vacuum leak, but were the hell is it coming from?Your hissing noise will be most likely the flapper vacum pipe on the rear of the exhaust. Does it hiss when you come off the power in town?
Also have you got a decat?
