Engine Number Sequencing
Hi All,
Looking to buy a 2010 S63 with the P30 performance package, however I’m trying to figure out if the M156 engine is in the range that has the head bolt issues. The engine number is 156984 60 059661, but I’m not sure how to read it. Could someone let me know? Thanks in advance!

Most M156-equipped Mercedes-Benz models up to model year 2012 have cylinder head bolts that have the propensity to break at the bolt head, allowing coolant to enter the combustion chamber. The cutoff for engines not affected by this design flaw is engine serial number 60-060658. You can find the engine serial number located on a white sticker affixed to the left valve cover.

I sold with around 70k no issues the new owner last we spoke had over 150k no issues.
This was a 07 W211 E63 with headers full exhaust intake and OE tuned ...I was told the very early motors had no issues.
