Engine seems to have a rap at startup (with video)
2015 S550 with about 16,000 miles. Only mods are a Roush exhaust and a JLT oil separator catch can. Lately I've noticed that when I first start the car when cold, there's a noise until it initially warms up (after about 20 seconds). Anybody know what this might be and if I should panic?
's a sweet video of my driveway where you can hear the noise.

It is hard to determine the sound in video almost sounds like a exhaust leak, I be surprised if it was a engine noise with that little mileage,
its still under warranty take it to the dealership if you are in doubt.
I have a 2015 with 18K miles and suercharged and quiet as a mouse I run Royal Purple oil though and it runs like a swiss clock
