Engine code spec decoder

Hi All,

Can someone point me in the direction of an engine number decoder or help me decode one please?

I need to get my engine replaced 651.950 xxx xxx xx and the mechanic is proposing a replacement with a 651.955 yyy yyy yy

I am concerned that the replacement may not be as powerful as the original I had so I wanted some help in decoding the 14 digit engine codes please. I want to make sure the HP and KW etc are of similar values by using the full engine codes/serials and not the VIN numbers.

Thanks!
JW

Did you ask the mechanic? Is this a dealer or an independent?

I did ask and was told it's the same just different top level models. It's an independent mechanic this time. I was hoping through the engine number I could work out the spec of the engines but I've been struggling to find that.

651.950 can be seen on V447 4Matic and 651.955 on W906 also with different power range.
