I can't quite make all the numbers out clear enough, but the numbers I could decipher it looks a 2 stage relay.
I have sent you my email, send me a decent piccie, as I can't enlarge that one, I'm crap on the compy!!
The relay is almost certainly made by bosch, if not it will be a siemens one under license, so may still be able to get one from them, may look different but do the same job.
