temp sensor part number W204 C350cdi

[steve-V8s]

Please can someone tell me the part number for the exhaust temp sensor which sits in front of the DPF on a W204 C350cdi.

I think it may be a0081532728


Also would be interested to know the normal resistance range. The part has a two pin connector so I am assuming it is simply a temperature dependant resistor. The example I have ranges from 200K when cold to 300k when hot, I would expect a bigger shift than that.
