Rattle when clutching in?

doug_999 · 02-07-2018, 07:46 PM

So it is winter and cold here and my car has about 400 miles on it. However the last few days, I've noticed what I originally thought was a rattle when clutching in (worse when car is cold). Tonight I listened a bit closer and it seems to be the exhaust - as I can hear it when clutched in and revving the motor - maybe it is just the ZCP exhaust? The odd part is it appears to come from right about where the trans is - and almost resembles the popping sound the car can make when in sport+ mode (I'm in sport or efficient when this happens) - but once again, it comes from where the trans is, not the rear of the car.

Anyone else have this? Normal?

I get a rattle sound when clutching in on 1st gear during certain engine loading conditions. I think it happens more when off throttle and engine is under load. It seems it is more or less normal.
