Well im no expert, but on my CL55, and my friends SL55 we both used Mobil to change the oil int he cars, and simply bought in our own filters, i guess they used standard tools, i didnt see them get too sophisticated nor creative. My guess is you might be able to get it done plain and simple.

I dont know if '06's are different or special in any way specifically towards the question your asking about, wish i could be more of service... Best of calling a local MB dealer and just ask a service rep to answer your question. Best way to get the right response for sure. Dont want to make any mistakes on that sweet ride!
