Autel MK808BT PRO 2025 Full Bidirectional Scan Tool

For me I was upgrading from older, less expensive “code readers/scanners” I had that were limited, to work on an issue that I had difficulty getting resolved at a dealer unfortunately. They other devices I had had less diagnostic capacity, other service features, and vehicle coverage than this unit did and it was clear my needs were changing and they were aging out of “updates” as vehicle technologies evolve beyond their design. They were one off-brand and one “tool truck” brand but both in the less than $150- 250 price range approximately in their day/s. I got my money and use out of them over the years for sure. so no complaints there.

I was concerned about this one being “off (or maybe better termed “new to me”) brand” name (Autel), and gave it a whirl. Really happy I did. In fact, I actually originally ordered one of their lower budget units like my predecessors were price-wise. When they found out what one of my vehicle project needs was during the purchase process- they suggested I get this more “powerful” unit for that specific vehicle and its needs because the original I chose would not cut it. Yes an up sell but the less expensive would have been a paper weight to me. I my mind that is great customer service! So we went through an easy- peasy exchange process.

The cost of this unit is similar to a couple trips to a dealer or shop (no offense to them), and about double what I was originally planning to spend. In general if you can use the information it gives you to properly execute repairs (which I could on the “cheapies”) then it is well worth it. It’s operation is all pretty darn easy to use, and I have really just barely got/had to use (to its full abilities) mine so far on a few of our vehicles in my family’s “fleet” so far but it has worked awesome! Really glad I found Autel and this MK808xx unit! Thank you for a great product!

Scanner kinda pricey, but is capable of doing a lot of diagnostic testing. Saved me 1/2 the cost trouble shooting a daughter’s car. No need to go to the dealer. The learning curve of use takes some patience. That’s the reason I’m only giving 4 stars. Need to get on line for tutorials. I’m old school, would love to have paper how to manual. Still I would buy again, and do recommend this product. 👍

Connected it up to a Holden Commodore and was able to find the fault easily. The scantool is easy to use and I was able to diagnose and repair the problem with the car. The scantool also gives live data readings on sensors and graphs the results in a easy to understand way. Also the customer support for the product are very helpful if you need any further information on the product

I purchased Autel MaxiCOM MK808BT from 𝘼𝙪𝙩𝙚𝙡 𝘾𝙝𝙤𝙞𝙘𝙚 US for personal use and dealer scanners at shop. 𝘼𝙪𝙩𝙚𝙡 𝘾𝙝𝙤𝙞𝙘𝙚 US customer service is excellent and quick communication. They responded my pre-purchase questions and prompt follow up after purchase to make sure everything is OK. Autel MaxiCOM MK808BT is Make in China and only purchase from 𝙤𝙛𝙛𝙞𝙘𝙞𝙖𝙡 𝙖𝙪𝙩𝙝𝙤𝙧𝙞𝙯𝙚𝙙 𝘼𝙪𝙩𝙚𝙡 USA 𝘿𝙚𝙖𝙡𝙚𝙧 to receive 1-year warranty, 1 Year free software update and required to register your device with Autel ID before using. You can continue to use MaxiCOM MK808BT with the last update software after one year period expire but you might want to consider upgrading every 2 or 3 year to service newer vehicles.

Key Features:

– Responsive Android based 7” touchscreen tablet with Bluetooth dongle. Scanning and reading is slower than OBDII cable version but Bluetooth adapter is very convenience and able to diagnose from work bench without cable running all over the floor. This is a good complimentary scanner for shop but will not replace dealer scanner or dedicated TPMS scanners.
– Good built quality with rubberized grip, hard plastic shell, kick stand and bluetooth dongle holder in the back. However, larger and taller rubber grip would be more useful and easy to grab and protect screen from drop damage.
– More internal memory needed for future software update and user data. You can however move some app from main memory to external MicroSD card. Internal free flash drive storage is less than 50% after software upgrade 16.77 GB, and total size 26.83 GB.
– Free 32 GB micro-sd card included in the scanner and very useful to backup the Autel Maxisys system (“Scan” data folder is a little more than 16 GB)
– One Touch AutoVIN & AutoScan for smart diagnostics work well and tested on Asian, European, and American cars 2004-2019.
– ABS bleeding is not available to all cars at least 2004 Mercedes ML350 or W163 2000 ML55. OK to ABS bleeding for 2012 Hyundai Elantra, 2016 Lexus ES350, 2014 Audi A3 and 2010 Honda Civic.
– Great tool to reset Mercedes Flexible Service System (FSS), and service interval
– Not all hot services SRS, IMMO, Oil Reset, EPB, BMS, SAS, DPF, ABS Bleed and TPMS are available for complete diagnosis and reset functions in routine maintenance. Contact Autel authorized seller 𝘼𝙪𝙩𝙚𝙡 𝘾𝙝𝙤𝙞𝙘𝙚 US with your VIN# before purchasing the scanner.
– Live data OBDII operations in 4 display modes (Analog Gauge, Text, Waveform Graph, Digital Gauge).
– Easy to upgrade database and update software via Wi-Fi. Free software and data upgrade only for 1 year but you can still use the last update software after one year free period expire. I would upgrade every 3 or 4 years so I can continue to scan newer cars.
– Easy to run, view and print reports for Smog Check OBDII Reference, OBD Test Monitor Readiness Standards and review incomplete readiness monitors for emissions test. Printing and Report only save the current page and you must open individual DTC and save individual pages as PDF file. Default saving location is internal memory. You can copy, and export to external Micro SD card or USB flash drive or upload to FTP, email.

I would highly recommend to backup the software and data so you can reinstall and recover software failure. You can easily backup complete data to external USB flash drive or external MicroSD card. You must use 32 GB USB thumb-drive or external MIcroSD card formatted in FAT 32. Make at least 2 backup files before your software subscription expired and run an update before backup. MaxiCOM MK808BT didn’t recognize USB flash drive larger than 32GB or NTFS formatting.
1. Run “ES File Explorer” software
2. Click on “Home” shortcut on left side of the screen
3. Press and hold “Scan” folder to select then click “Copy”, then open external-sd or usb_storage drive then “Paste” the folder to complete the Autel MaxiSYS Data Backup. It took 1hr and 15 minutes to backup a little over 16 GB “Scan” folder.

I would recommend Autel MaxiCOM MK808BT from 𝘼𝙪𝙩𝙚𝙡 𝘾𝙝𝙤𝙞𝙘𝙚 US for more advance user or backup complimentary scanner for shops. Large screen is very useful to analyze and view Diagnostic Trouble Codes (DTCs) OBDII and save data file as PDF then upload to FTP, cloud, email, print or save to external MicroSD card, and USB flash drive. Make sure to verify and record Diagnostic Trouble Codes (DTCs) before reseting DTC faults/Check engine light. After you reset the codes make sure to perform a basic drive cycle or manufacture recommended methods used by a vehicle’s powertrain control module (PCM), repair or replace faulty parts then verify IM Readiness Monitors.

Autel MaxiCOM MK808BT is very useful to troubleshot IM Readiness for SMOG check with live data. If your IM Monitors failed after normal basic drive cycles then verify these:

* Verify to make sure you have good alternator, battery, and 02 oxygen sensors
* Fuel tank between 1/4 and 3/4 full. Your system will not clear IM readiness if you have too much or too little fuel
* Mixed driving mode and various stages of the Drive Cycle in the city and freeway for 100 miles between 35 and 55 mph. Do not pass 55 mph. Slow down and stop your car a few times in safe location with wide shoulder lane without using foot brake but you can use hand brake or emergency brake. 10-20 miles “Several trips” required and let the engine start and stop between testing.
* Verify, test and replace weak O2 oxygen sensors and Mass Air Flow (MAF) before swapping catalytic converter. You might have to replaced failed catalytic converter if you hear rattling noise when starting the vehicle, and will get worse over time.
* Oxygen Sensors and Catalyst monitors are also not ready, the culprit is most likely a weak battery.
* Catalyst monitors are not ready, the culprit is most likely a weak O2 Sensors. Typical error code P0420 Catalyst System Efficiency is below the threshold
* AIR (Secondary AIR) monitors are also not ready, the culprit is most likely a weak O2 Sensors.
* EVAP monitors are also not ready, check for a loose gas cap. Replace damaged or cracked O ring or replace new gas cap.
* AIR (Secondary Air Injection), and EVAP readiness required from COLD start. Keep your car at Parking mode and slowly increase the speed to 1500 RPM for 10 minutes and make sure the normal operating engine temperature is in a range of 195 to 220 degrees Fahrenheit then return to idle at 800 RPM for 1 minutes then press and hold the brake while putting the car in Reverse Gear then accelerated slowly for 40 seconds. Make sure to hold the brake so your car is not moving then change gear to parking mode and shut down the engine. Start engine again to verify the AIR readiness.
* Repeat the Basic Drive Cycle multiple time from COLD start in the morning. You might have to drive multiple basic drive cycles of 10-20 miles for a few days for all monitors to ready.
