Hey guys, I bought a 2019 C43 AMG about 4 months ago and I have had so many problems with this car already. I bought the car with 13k miles and now has 18k miles. My first month the car would crank but no start and it stayed at Mercedes Benz for about a month and they changed my ECU. Later down the road I start having these weird turbo sounds on acceleration and they sound like rust spinning around. Finally I have the most annoying exhaust sounds at higher gears and a lot of vibration in the throttle and exhaust mostly heard to the right side. I have spent so much money and no one is able to figure out what’s wrong with my car and it’s driving me crazy. I will tag a link to the videos I just uploaded and if someone can please help me out, thank you.
