Hi Gang,

My 2010 has developed this chattering noise, heard while inside the car. It's intermittent, in that it starts and then stops and then starts up again. I have found that it happens when driving. The next time that I drive it, I'll pop the hood. Any thoughts?

 

I had a severe rattling that I thought was something to do with the supercharger, but it turned out the water pump (what a surprise) was vibrating so badly it produced a prodigiously loud rattling. Check your water pump.

 

 

In my case it's the SC snout, it's not that pronounced and indy has told me not sufficiently bad to warrant a replacement as yet.
