Yesterday I got the "Check Lights" malfunction and it turned out to be the one of the "not so obvious" license light bulbs. I did replace both of them and put this DIY together in case one might need it later on. Cheers.
Hey, Kobus. I went back and looked at the old DIY stickies (the ones I "decommissioned" when redoing them all into the new format) and didn't see it in there, so apparently it got mishandled sometime prior to that. Joe55 was otherwise copying the DIYs from here to the AMG210 forum and it's not in that one either. To be honest it is easy to make a mistake while working on them and if I was the one who accidentally knocked yours out you have my apologies. I am glad you added it to this one so that both are again available.A link also to a DIY I posted back in 2007 on this same topic. It seems to have disappeared from the stickies.

Definitely not possible on the face-lift model...I didn't remove the inner liner? I just unscrewed the three Phillips bolts on the trunk lid handle and removed that. Popped out the bulb holder and replaced the bulb. Did it in the parking lot of a Canadian Tire store, took about 5 minutes.
I removed the bulb holder by gently pushing it to one side and then it just lifted out.
