* 606.910 is a 606 for a W124 E300 Diesel
* 606.912 is a 606 for a W210 E300 Diesel n/a
I think the main differences are that the W210 has an in-tank fuel pump (though maybe only for the turbo car) and has a fly-by-wire throttle. So probably the IPs are different
The auto boxes for these two cars have a very slightly different part number as well but the only difference seems to be the speedo drive
