Hey all,

First let me introduce myself: I’m Jonathan...proud new owner of a 2017 f-type SVR. Love the car! It’s truly an honor to be able to drive this fantastic piece of automotive machinery...

Now onto the question:
When I’m driving with the paddle shifters (both in dynamic and just manual mode), and I downshift to 2nd gear, there is this odd mechanical sound that emanates from the rear passenger side of the car. It sounds really electronic, as if something is being engaged or something. It’s quite noticeable. I don’t hear it if I downshift down to 2nd at a higher speed like 32-42 mph (which is pretty high speed to be downshifting down to 2nd!). If I downshift down to 2nd in the high teen mphs or even in the 20-27 mph range, it comes on like clockwork! Anyone else ever experienced this?
I started to downshift the car from 2nd to 1st at literally a standstill, in order to avoid the noise in 1st gear as well.

Any help or suggestions would be greatly greatly appreciated...Thanks!

-Jonathan

My guess is that the sound is related to the exhaust valve movement in the muffler. Does your car have the selectable exhaust?

Hey guys, here is an update on this issue: After taking a longggggg test drive with the shop foreman at the local JLR dealership, it's been determined that the noise is most likely coming from the active exhaust flap. When the car is coming to a stop, the flap closes. At a stop or (low engine speed), the flap stays close to increase torque. It then opens up at higher engine and vehicle speed to increase horsepower. Once the car is coming to a stop again, the flap closes......All in all, it's a pretty "standard" noise (although any loud noise on a Jaguar is potentially ominous lol).
