This just happened and I'm at mercedes right now. My car started idling really rough and while accelerating the car would shake a bunch especially in the low rpms and higer gears. The check engine light just popped up. Has anyone had this issue before and have any idea whats happening? I drive a 2014 c63 507 with a eurocharged tune.

Pull the code first. It's hard to say without any sort of codes. Im guessing a missfire. But like I said, pull codes and you'll get an accurate reply.

Thats what the guy said at mercedes maybe a misfire. What does that mean?

SuperFastYo

its when a cylinder doesn't fire correctly. If you brought it to Merc, why don't you know the code or have them fix the issue?

matthewb

I just got to mercedes
thanks for helping i should find out what happens in an hour

Cool, good luck! If it's just a coil pack or spark plug I say you pay the diagnostic fee and bounce. Those are easy fixes. idk how much they will charge but I'm sure it'll be too much.

I do have a warranty so it might be covered by that

I also have cars and coffee tomorrow and i really dont wanna miss that because it's been down in my town ever since i got my car

I keep meaning to go, but never do. I use to go to Irvine's a lot.

They said that it was misfiring and that there was new coding for the engine that they put in and they are making sure the problem is gone. Does that mean it affects my eurocharged tune?

SuperFastYo

Yup, pretty sure.

Re download your original file from the car and send to EC, Jerry can take a look at it and let you know. They will prob make a new tune for ya if needed, more than likely for free.

Do you have a V6 tune by chance?
