My first misfire - 2019 AMG C63s Coupe
To my knowledge, MB is using my car as a test unit and I won't be surprised if they apply these fixes to those with similar issues in future. This fix has parts upgrade followed by Trani, Drivetrain, and ECU firmware modifications. At this point, they keep on updating the software, testing the car and logging the behaviour.
@E55 KEV what's your built date?
By the way guys, I've lost my patience and faith at the moment and hoping to get compensated for all this inconvenience. I've gone through 2x C300, and 2x GLC350e loaners already which are dumb and dumber cars if you ask. Summer is almost over and I haven't had a chance to enjoy the car yet





They’ve had yours way too long. I’d tell them to keep it now. Hopefully they’ll be ok about it. In fairness, Jaguar were. I actually got back more than I paid for it (bit of compensation from their finance guys plus the road tax). I also told them that whilst I liked their E Pace I actually owned an F Type. They obliged by getting me a brand new one as my loaner.
I hope you end up with a good outcome too.

I finally received a call from my new SA confirming that my car is fixed and all the issues are addressed but I can't pick it up until the detail the car so I'm expecting a pickup on Monday, Aug 26th.
During this 2 month period, I've noticed the car has been driven around the dealership (on my Mercedes Me app) , turned ON and OFF for hundreds of times and even driven to technician's house which is about 35 miles away from the dealership and stood the night and was driven back to the dealership. I'm seeing 122 miles added to the car since my last drop off. I also understand that all of this was for testing purposes and I shouldn't make a big deal out of it but I'll have to physically inspect the car when picking up and make sure they notate the correct milage on my paperwork.
My SA also mentioned that shop foreman will give me instructions on how to drive the car? 😂I'll keep you posted once I pick her up.

I hope your patience is rewarded with a car that is truly fixed and runs well.
Keep us posted.

Mind if I ask what was your story? Why did you get rid of yours?

I was able to pick up the car earlier (after 69 days) and was told by the shop foreman to enjoy the car (no driving restrictions since I've already passed the break-in period) and I did!
I drove the car aggressively for 5 miles to my office and didn't notice anything but lots of joy!
Below are the RO notes in case you're curious. I'll keep you posted if anything comes up with my situation.

You've got one beautiful car.
I went back to Audi and have had a good few weeks in the new car.

I wonder what others have to say for this?
I drove the car aggressively (for the first time) and got a misfire followed by solid CEL and after rebooting the car, everything went back to normal and CEL went away.
Drove the car aggressively again and no issues. Trouble is, I need to find a better place to avoid obeying the laws and push the car very hard and see if the issue comes back.
At this point, I went ahead and notified the dealer but will drive the car over the weekend and see if the issue comes back. Any suggestions/ideas?
