Exhaust leak? Need your thoughts...

Hey Fellas,

My 147 seem's to be making some un-natural noises. It can best be described as a high-pitched 'steam release' noise when i turn the engine off, almost sounds like a BOV but much more quiete. There is also a 'crackle' when i release the accelerator that is hard to pick up but its there.

A mate of mine has suggested an exhaust leak, and that would probably explain why i feel a loss of performance?

Giving the car a good hit no longer pushes me back into my seat, it still sounds beautiful but it just doesnt feel like it did 2 weeks ago.. I cant put my finger on it.. The engine screams but, its just not right.

This could be partially due to the switch of petrol recently, both 98 octane but from BP ultimate to Mobile 8000 (seems like dirty petrol).

Also, is it normal for the engine light to remain on while the key is turned to ACC? As soon as i start the car, the light turns off.

Urgently awaiting your response,

Re: Exhaust leak? Need your thoughts...

engine light will be on until shes started up.

easy way to check for an exhaust leak, put a damp towel over the tail pipe as to block the gasses exiting, leave her running for a few moments and visually check teh entire system, you should be able to see where shes leaking if she is. a good tell tale sign is black soot around the leaking area. again, dead easy to check.

a switch in petrol shouldnt be the cause tho
