innova 3030 Code reader problem CLS500

I have a 2006 CLS500. The cel came on this morning so I checked it with my innova 3030. The code was a P0442 which is probably a gas cap or other leak in the evap system. The problem is that when I select the checkmark button on the reader it tries to erase the code, but after a while says FAIL. I had bought this reader for an Audi and it works well with the Audi. I can read and erase codes. Has anyone used this reader on an MB? Is there another reader that is not too expensive that will read and erase MB codes?
Thank you,
