Autel MaxiDiag MD806 OBD2 Scanner, 4 Systems Diagnostic Scan Tool

Exactly as adverised and have been using it well!

It does everything I expected and a bit more. Works with my 1996 Audi, my 2008 BMW, and a variety of Mazda, Ford, and Toyota vehicles. I think it counts as “two way” because it can tell the computer modules in the vehicle to do a few things. I was concerned that it might not work so well with the German vehicles, especially the older Audi, but was pleasantly surprised that it’s able to communicate with the main ECU, the airbags, the transmission, and the ABS. The UI isn’t perfect but it works. It gives complete and clear identification (manufacturer, model, software version and sub-version) of the computer module it is talking to. It at least currently doesn’t unlock frivolous features on my BMW like some of the BMW-specific software does, but it can interrogate the state of all the switches and sensors for really convenient fault-finding, and can reset service lights/intervals. I believe it can release electronic parking brakes, although I haven’t had to try that yet. I say “currently” because Autel does seem to release software/data upgrades for various models, downloadable (free so far) from their website once you have registered. It extracts and resets freeze-frame and other OBD II data (smog test readiness monitors) just fine, as you would expect from any modern diagnostic tool. I haven’t figured out if it is possible to simultaneously plot more than two live sensor values at a time, but two has been enough so far. (Eight values for a V8 would be convenient, for example.) A little more model-specific repair advice from the fault codes might be nice, but it’s only a tiny inconvenience to type the code into Google on my phone and get a ton of advice from all the forums. Comes with a decent blow-molded carrying case that should keep it stored safely. The device exterior seems rugged and sealed enough that the normal shop environment shouldn’t kill it. The screen is easier to scratch than I like, but maybe I can find an iPhone screen protector that fits. It’s not a touch screen. I would like a longer cable on the OBD plug, but I do have my own extension cable for those times when I want to work from the engine bay instead of the driver’s seat. All-in-all, this is a lot better value than any other scan tools I have purchased. It’s enabled me to find the exact problem with a complicated BMW (GM!) transmission (awd transfer case) and repair it for a few hundred $$$ instead of the dealer’s proposed $4,500 complete transmission replacement. It’s been very well worth the money for me.

Over all a good tool for the price. The screen is larger than other models of OBDII scanners I have seen. I was also impressed with the buttons on the tool. Rather than a key pad they are soft rubber buttons that push easily and allow much easier navigation. The carrying case provides adequate protection without being too bulky. Just the right size!! Three main options on the home screen. Scan - Which will scan automatically once a couple of parameters are set and will provide any trouble codes present from the 4 systems the tool can access. Engine, Transmission, ABS and SRS. It will also provide live read out data although navigation through the live data outputs is slow. The ODBII menu provides much of the same data as the Scan menu provides. There are 6 functions in the Service menu. Oil Reset, EPB, SAS, DPF, BMS and Throttle. Most of these services are needed and used on newer vehicles. I was intrigued with the BMS as this was the first time I was made aware of this function on newer model cars. Over all a very good tool providing the essential information needed for diagnosing OBDII fault codes.

Does as expected, easy to use and diagnose/clear code easily.

very good
