I've just got it from the dealer and found out that my OBD code was 4D35 - metering valve clogged. The work that they did was "replaced SCR valve as per sib...."
I hope that I'll be luckier than this guy:

It's the second SES for the last two years. The first one was at 4K and was related to Eurea injector failure.
My X3 is almost 8yo and I didn't have any SES so far. Did they test 335d well?
