As many of you know, I have been providing Datacard info to many members interested in their build sheet, or to verify engine serial number.


I received a PM from a member today who indicates he has a "late 2010 C63". The Datacard for the VIN he provided shows a delivery date of 11/24/2010. The Datacard indicates the engine number is over 4,000 engines beyond where the new head bolts were employed.


Since we've believed that all 2010 and older, and some 2011s were in the affected range, I'm confused about how this one could be outside the range. I did a search to find out which digit in the VIN corresponds to the model year, but had no luck getting a clear answer.


Anyone have any thoughts on all of this?


Thanks,


Joe

The VIN is WDDGF7HB8BF632794
Thanks for your time and help Joe!!

Who's your engine builder?

A couple weeks ago my coolant warning came on for the first time, the car was parked outside for several days in below freezing temps and my driveway has a pretty steep slope. took it by the dealer and they toped it off....a couple hundred miles since the top off and were good.
