2017 C43 cabriolet exhaust/engine purring noise
Hello every one, this is my first post in this forum and I must say I love it and it helped me a great deal before leasing this vehicle. Now, after owning the vehicle for a couple of weeks, I started to notice some purring or weird (can't really describe) noise from the car (probably exhaust) when accelerating. I've the performance exhaust and the valves work when I push the button however that noise (as if there is a hole in the exhaust or the engine) wasn't there when I first test drove the car.
Any suggestions? It's quite annoying feeling that this car is faulty, especially after overtaking that lease by just 2 weeks. I'm not sure if it's some in all C43's or just mine.
I'll try to post an audio or a video clip but it's not going to be very clear though as when I hear it while driving the car.
Appreciate all the input!
Thank you,
