How do I tell what engine type / code I have?

[uumode]

E 240 W210 chassis with 2.4 engine two sparks per cylinder 1999 model year?

In the handbook, there is a 111 ML, 104, 111, 112, 119, 120 ?

I think its a 112.

I think its a 112.

I just found this out

Engine 112911 30 082920
Transmission 722609 10 636412


so I guess it is a 112. or sheer coincidence that the first 3 digits are the same.
