Hi guys, what's up. I own a C450 AMG. It has been working great, but recently I found that my car's backfire has disappeared. In S+ or any mode, I no longer hear the explosion of the exhaust pipe. ![Frown](https://mbworld.org/forums/images/smilies/frown.gif)
The entire car was working properly and there were no fault lights. I can't find out why... anyone can help?

I should ask - did you refuel recently? MB told me that the car can be affected if you don’t tighten the fuel cap properly.

Well i"m interested in what stopped the backfires...but for a different reason. I am one of the folks in the minority who really doesn't like the pops and crackles from my 2019 C43 with PE . If there's a way to eliminate them without affecting drivability or performance, and not throw any codes, I''d be a happy camper. Subscribed to this thread.

Okay... A little update here, the backfire just came back this evening(yeh!!!).
I still don't know what caused the backfire disappearance, but I am boldly guessing that there is a problem with gasoline. I have always been a big fan of SHELL, but In the past few weeks, I tried the NO. 91 gasoline FROM 76. It doesn't take long, maybe only a few days later, the backfire sound disappeared and the car accelerated to become negative.
I didn't say that the gas from 76 is bad for our AMG model, butttt I won't try any no.91 gasoline from 76. Never!
Before the backfire came back tonight, I have completed three refuelings, they all come from the shell. If your backfire sound disappeared, try replacing the gasoline. If it doesn't work, pls go to the dealer (I just canceled the plan for tomorrow... backfire is really back on time).

Ok, since it's the same octane, it's ok. Could be the quality of the fuel itself then. The C43 is originally made for 98 octane (RON) which is equal to 93 octane in the US (and Canada, I suppose). But I guess the engine is adjusted/adapted to the fuel available where it was sold.

Yes this happens
Yeah I too own a c450 our pops and crackles come and goes, this is very odd. Sometimes it’s extremely loud and there r times that it doesn’t make a single pop at all. I still couldn’t figure out why tho🥲

Have you lads considered an actual AMG? That may solve the problem.

Love people that think they know more than either the history of a company or the company themselves. If you bought your car and don't know the history of it, but feel the need to troll another form..... That says it all. Your girlfriends must be underwhelmed.

Based on his baller ride, along with his history of 26,259 posts, I think we are out-gunned.
Think of an angry old man whose real life is sitting in front of his 15 year old Dell desktop while getting-off by trolling folks on the internet.
That said, I will concede that his CLS is probably a real a home run with the babes; at least when he rolls up at the local assisted living facility.
