Please click the user cp link and complete your BW profile for vehicle and location as that is often useful information.
Also, you're up in the general forum but there is a forum specific to your chassis, the W210 forum, scroll down and you'll see it. It's quite active with lots of good folks and a slew of help/diy tips that are in stickies...including one for translating those pesky codes to something more meaningful.
The P0455 code is a perceived leak in the evap recovery system, quite often that is triggered by a failure to properly seat the gas cap, so check that out. If not then you could replace the cap (it's almost ten years old, you might be able to find a new gasket for it). Cleaning the purge valve would be next.
The 410 code is for the secondary air injection pump. That could be related to the evap code, so I'd first focus my attention on it, then clear codes and see if the AIP code returns.
Take care and enjoy the ride,
