I have an Autel Maxiscan MS300 that works just fine to clear DTC codes but I need to clear transmissions codes on my 98 C280 and it is not capable of that so I bought a Autel MD 802. The MD 802 has the capability to clear the code but you can not use just any cheapo ODBII to 38 pin adapter, which I have found out by researching different forums. It needs a specific Autel adapter. From what I have read it needs the Benz-38/DB15 Femaled for Autel DS708 that cable on amazon is $112.99. I haven't purchased that cable yet but I have different cable on order right now, the BENZ-38 Adapter for Autel MaxiSys MS905 MS908 MS906 $ 29.99 on amazon, to see if it will work and if so I will post it here for you. I had tried one of the generic adapters and all that I got was a link error.

Here are a couple of links to some info that I found about a 38 pin adapter for the MD802:
