    Engine number

    How do you find the engine number?

    Someone posted on MB Forums re head bolts issue

    "Engines affected are M156 up to engine # 569xx 60 060658"

    I have been following this and from what I gathered the head bolts have been changed somewhere along the line. Heads have been lifting causing all sort of coolant related problems from simple stuff like coolant usage to hydro locked motors.
    I am not sure how the guy got that range of motors and would be interested to find out. I am taking the heads of my car soon so it will be nice to see how the stock head bolts are managing. Moving to studs which I already have from Weistec so this will not be a concern for me.

    I have a 2010 ML63 and 2010 C63, both of which are in the range. I subscribed to STAR TekInfo and found the service bulletin:

    01-05-2012 Star Bulletins Click here to enlargeLI LI01.30-P-051567_Ver.1a
    LI
    (0bytes)
    Check engine light (CEL) on and low coolant indicator lamp lights up
    M156 up to engine # 569xx 60 060658

    As you can see by the byte count, it's an empty document and returns an error when selected.

    Perhaps someone can get the details and actions MB will take if one experiences the problem.

    Regards,

    Joe
