I have the same model car and the c310+ -- it's worked great for me so far! Only thing I did notice was that despite some saying the C310+ could reset the airbag light - I couldn't figure out how, and the SIM/SRS error clearing didn't do anything for me, but other than that It's a handy piece of kit for a fairly decent price.
(I have ISTA on a laptop so I cleared the light using that fwiw)
