CALLING ALL U.S. 2019 C63S OWNERS... POPS AND BANGS COMPLAINTS NEEDED ASAP
Calling ALL U.S. 2019 c63s owners!!!!
Please call MBUSA and complain about the lack of pops and bangs.
I called and talked and filed a formal complaint after the dealer told me to and the MBUSA rep(Isaiah) confirmed that sales and service DO NOT file formal complaints like this in the U.S. You have to call the Mercedes customer service number 1 800 367 6372.
I think you have to press 5 both times to get to a rep. I got one in like 20 seconds of waiting so it shouldn't take long.
Literally 20 minutes after I called the rep called me back and said there is a bulletin to respond to this.. Saying the 2019 had to be made quieter thanks to new U.S. regulations. But there are no new regulations.. only California has a new law which forces officers to write a ticket if a car is louder than it should be. He stressed this was a software issue done for U.S regulations on noise. He also said he will be calling me if any new info comes up regarding this and will touch base in 1-2 months time. Funny thing is i just read an article on the r8 and while the EU model gets the 10hp bump this year and is more muted because of the new EU noise regulations the U.S. model gets a better sounding exhaust.. they focused more on the sound here because of epa regulations on emissions.. so that directly contradicts MBUSA statement to me when they called back and said it was U.S. regulations on noise.. Once again Mercedes is lost in their own interweb. Lets get them to straighten this out!!!!!
The Customer Service Rep(Isaiah) said to get people to complain and AMG will definitely update the software and get it closer to the legal limit. So please call that number and get those complaints in ASAP!!!
They only need your phone number to pull up all the car info and document the complaint. I just explained how the car sounds much quieter than the press cars in all the reviews and how those cars even had particle filters and ours do not.
Lastly I'd like to thank Roken for bringing this up and making me dig around and ask who to contact to file a formal complaint in the U.S.

I filed a formal complaint and requested a “claim” number. Make sure you ask for it so that you know your complaint was lodged

The funny thing is they actually have a response ready for this.. Did the rep call you back and explain the situation like my rep did?
Even if the exhaust is totally muted I'd still take the updated 19 over preface lift no second thoughts !!!
If all else fails, an aftermarket tune will easily fix both problems and add all noise and "snap, crackle and pops" you want LOL
My 2019 exhaust is louder than my 2017, and there is a marked difference
between exhaust on and off when the performance exhaust is selected comfort mode for the 2019.
I have still not completed running in, so will update as and when I do.

That's Great news!!
Isaiah doesn't BS and he stays on top of things and if he doesn't know the answer he hunts for it.
Thanks for the update!!
my ‘19 is plenty loud but there is no pops etc on downshifting to speak of. Just an occasional one.
I agree that more calls will reinforce the possibility of the sw modification.
