Default Mine sounds like loud Diesel engine at idle? - 28th June 2017, 07:43 PM

Hi,

My JCW at 264 miles goes great but sounds like a Diesel engine on my driveway.

Is this normal? Just sounds loud on Sport and little quieter on Green mode.

I was thinking injectors but with the windows down it sounds like an old London cabbie lol.

My dealer told me to keep an eye on it and bring it in for a checkup.


What does your JCW sound like at idle?

Thanks.

Direct injected engines do tend to sound like diesels on idle.

Mines a bit rattly at 20k miles. I'm used to it and have owned a few direct injection BMW's which all sound the same. Mine had its first service at 18k and it sounds quieter now. Not by much. I hear that a different oil is used from the factory for new builds. Not sure how true this is. But might explain why mine now sounds better.

Direct injection engines are "louder" than their standard cousins.
But make sure it isn't timing chain related the n12-n18 engines are known to have the plastic guide rails disintegrate.
