Thanks for your response, it was very helpful. I currently have the MD802 all sys for a few years (extremely useful) and I"m looking to upgrade to a bi-directional scanner. I know there is no one tool that does all but will the ms906 do most of the stuff out there?
The reason why I was asking about the difference in the models was because I was getting different answers from other sources. Some sellers post comparison charts and write that only the ms906ts/bt and 908s have andvance coding (what ever they mean by that) but not the MS906 base model, and one seller was telling me that the ms906ts/bt has more capabilities (besides TPMS) than the 906. the autel website states "Complete capabilities for codes, live data, active test, ECU information, adaptation, matching, etc." with the MS906 but with the ms906 bt/ts they ad the words coding and advance ecu coding in the features. Not sure what they mean by that. I spoke to 2 reps from autel and they didn"t know what I"m talking about, they said like what you said that the difference is in the hardware but the software is the same, they get the same updates. I think I"ll conclude that it's just a difference in the hardware, the words coding or advance ecu coding are just for marketing purposes.
