Yes, but I'd need to jack up the front of the car!
I expect Bundybear is right. The vaporiser should not affect engine temperature, which certainly happens on my MB.
It looks like they started fitting the vaporiser when the diesel became Euro 5, which happened during 2010. So mine could be either. I tried to check on ETIS but you now need to register as a business to see the vehicle specs, and I couldn't be bothered.

They are certainly a better way to do a regen than squirting extra fuel into the engine and hoping!
