Bad news after 1 month!! Cel, check coolant, smoke!
 

So picked up my 09 a month ago with 11k miles from Mercedes greenway in Houston. 700 miles later... I'm sitting in traffic last night and all of the sudden starts shaking at idle, heats up, coolant light comes on, cel comes on, and white smoke out of the back. Pulled over and got towed to dealership.

Here we go :(

:(

I know your pain, been there....GL

do you mind telling me what they did and how everything turned out?

here you go https://mbworld.org/forums/c63-amg-w...ant-issue.html

I would strongly suggest that you read up on all of the coolant/head bolt threads (there aren't that many) before you talk to your service tech. You can compare symptoms and outcomes/costs with the folks who had to go through that exercise. It should also give you negotiating power.

fortunatley I have the factory warranty still on the car + cpo warranty, then an extended warranty after that. I just hope they change the head bolts and get everything right instead of just masking the problem

Sit there with them while they do it and make sure they use the updated headbolts and not the same ones again.

I'm amazed there hasn't been a formal recall for this. any updates anyone have on the litigation underway?

That's why you need to research the issue. So you know what a true fix entails.

There is a service bulletin for the head bolts now. They will follow it.

If the bolt head popped off completely, it will have be shot around the head like a arcade game.

There has been a blank service bulletin out for a while (typical boiler plate language in it, but no details). At least that I have found, can you post, or provide the link to the current SB.

this could be fuel injectors based on some of what you are saying. shaking / smoking..

update today. "looks like its going to need a new head gasket."

Tell me they're going to change the bolts too. They have to take them off anyways, so they SHOULD.

They will, they are not reusing the old bolt style anymore.

I know that they should, I just want to make sure OP knows that it is supposed to be done anyway.

thx guys.. I told my service rep about the bolt issue and please have them use the new bolts. He said don't worry, they know about the issue and everything will be done right

that's good news. Can you ask your service rep if there is a TSB that replaces the old bolts BEFORE failure? I know warranty covers after failure, but what about a preventative TSB?

:y

I actually asked that when I bought the car from them a month ago. Unfortunately no such luck

Don't rain on my parade...
 

good luck with it and I hope they fix it correctly....

Good news!! They put me up in a brand new c class all week, and I got my car back today. Turns out 'some' head bolts broke.
"Installed all new cylinder head gaskets, head bolts (upgraded bolts), lifter hydraulic tappets, all other listed gaskets. Perform 2 engine oil and filter changes. Perform multi point inspection."

Best case scenario. Great news :)

Good to hear it worked out for you.
If anything happens to my motor I have a good reference to use and a local one at that.
Thanks for sharing.
