Did I just get a warning of things to come....or an isolated incident never to happen again?


This morning I got in the mighty Benz to come to work. I turned the key fob and the car started, but SHOOK HORRIBLY and the check engine light came on. I backed the car out and put it in park, revved the engine and hoped it was just some moisture in the fuel line that would be blown out with a good punch on the pedal.....no luck.

Then, I turned off the car and re-started. Problem gone...completely, not even a stutter...no check engine light either.

This thing was shaking so hard, it was like one or more of the cylinders were not firing and was thowing the whole cycle off balance. I assume that whatever was wrong, it was a computer control issue, because upon a "reboot" all was well. Subsequent starts of the car during the day failed to repeat the problem.

The car is 2.5 months old and has 4,000 miles on it

....so, was it just a one-time issue, or is this a sign of things to come?

hmmmm... I had a mis fire on my 550 not long ago and it DID store the code, that's how I was able to verify the cylinder miss.......
and it did freak me out......

good luck!

Oh Momma,,that sounds like a scene from the Exorcist,with low mileage like that I'd be 1st on the dealers to do list.

I guarantee the computer stored a code and or the incident.

This only happened to me once, but the car was outside on a very cold day. (-10C, 14F)
I blamed the outside temperature, not a fault on the car.

I would bring it to the shop and see what the error log shows. I would find out before it happens again.

Keep us posted.

Mr Snappy

I agree....taking it back for a looksee at the codes.
I will keep you posted.
