$3,400 sounds like a great deal.

Has been a little over a month since the repairs were done and she is running flawless.

Any one have a procedure for doing this DIY? I would like to try this myself since I have done some rather intensive work in the past, such as rebuilding a manual transmission, etc. Or am I way off base and should not attempt this? How can you tell that they are old style bolts that can break?

PM AMG3.2 who posted on this thread, he has what you need.

Can you check if it is affected wddgj7hb3cf824186?

No it is not, none of the 2012's are affected.

my condolences.. you got a really good price on the job though. this makes me want to sell my 09 c63 immediately.

Sorry to hear. Did you get a low coolant light or you just notice by checking under the hood?

You guys know this thread is three years old, right?

And he said in the very first bullet point that the low coolant light went on. Pay attention please.

Good thread for educational purposes though. The head bolt issue is real and those getting into anything with an M156 need to know about it.
