    Hi guys I've had this rattle on the car for a little while and never be concerned as it doesn't seem to affect the running of my car, when it idles I can hear a rattle at the back of the engine behind the fuel rail like tappets or something? Like I said doesn't affect the running of the car, I was just wondering if anyone else has had this? And possible fix as it more annoying than anything.

    Thanks simon

    Sounds like its the can chain tensioner tbh... do you get a 'brrrratttt' type noise when you start the car?

    Tbh I can't hear anything when I start the car, more if the bonnet is open you can just hear this little rattle/ tappets kind of sound, get a little louder if revved up a bit
