Correct thermostat for E300D OM606.910?

[benedict]

Hi,

I replaced the thermostat in my E300D today as my car was running cold (about 60C). It was clearly broken when I had a close look at it. It is now running between the 80 and 100 mark at about 90C.

Question is: Did the parts supplier supply me the right one? It is a Behr with Art no. 213685100 on the box. On the suppliers stick-on-label reads W124 300D(om603) 14G6.

I have an E300 OM606 not 300D OM603.

Does anyone know if these are interchangable/universal?

Thanks.
