Autel MK808BT: Why is it one of the best vehicle diagnostic tools for small shops?

The Autel MaxiCOM MK808BT delivers an OE-level diagnosis that includes basic, advanced, and professional functions. This mid-range device resembles a tablet, which makes it relatively easy and fun to operate.

But how does it perform? This Autel MaxiCOM MK808BT review looks at the main features and functionality. We have also covered how it compares with other similar scan tools. So buckle, and let’s get started.

Autel MK808BT vs. Autel MK808 vs. Autel MD808

As you can see, the Autel MaxiCOM MK808BT is quite a reliable scan tool. It’s not flawless, though, and for that reason, you might be thinking of looking at alternative tools. Two that come close to the MK808BT in functionality are the Autel MaxiCOM MK808 and the Autel MaxiDiag Advanced MD808.

Autel MaxiCOM MK808

The MaxiCOM MK808 offers the same functions as the MaxiCOM MK808BT. That includes full-system diagnostics, live data, freeze frame data, service reset, oil reset, IMMO, BMS service, EPB service, SAS reset, TPMS sensor relearn, DPF regeneration, and basically everything that you’ll get in the MK808BT.

So what makes them different? Bluetooth connectivity. While the MK808BT has a built-in Bluetooth module, the MK808 doesn’t. So if you prefer a scan tool that allows for remote diagnostics, the MK808BT edges the MK808.

Autel MaxiDiag Advanced MD808

Compared to the MaxiCOM MK808BT, the MaxiDiag Advanced MD808 can be termed as basic in functionality. Although it too supports full-system diagnostics, live data, freeze frame data, oil reset, BMS service, EPB service, SAS reset, and DPF regeneration, it lacks some functions that the MK808BT offers.

They include service reset, IMMO, and TPM relearn. It, therefore, just falls short, especially if you need professional-level functionality. On the upside, it costs less than the MK808BT.

Features and Functionalities

The Autel MaxiCOM MK808BT is built with Android 4.4.2 KitKat. And with the tablet-like design, operating it is a breeze. If you know how to use a smartphone or tablet, you can easily find your way around the MK808BT.

It has dimensions of 9.4 x 5.9 x 1.4 inches, which makes it easily portable. That’s an essential consideration if you are a mechanic and need a scan tool to walk around with.

It’s undoubtedly a well-designed device. But how does it go in terms of functional features?


The MaxiCOM MK808BT connects to the car’s computer wirelessly via Bluetooth. Its package includes a MaxiVCI Mini that plugs into a car’s OBD2 port and acts as a link between the scanner and the car’s computer systems.

Connect the MK808BT with the MaxiVCI Mini via Bluetooth, and you will be useful to run diagnostics. It allows a range of up to 33 feet (10 meters), which is pretty convenient if you want to do remote vehicle diagnostics.

Vehicle Identification

This Autel scanner uses auto VIN to identify a vehicle’s make, model, and year automatically. The good thing about this feature is that you won’t have to manually enter your car’s information unless it’s missing in the scanner’s database.

On the downside, it’s actually possible that the Autel MaxiCOM MK808BT might not have your car in its database. Some models, especially the latest ones (from 2015), cannot be identified automatically. In that case, you will have to enter that information manually.

Basic Diagnostics

As a full-system diagnostic scanner, the Autel MaxiCOM MK808BT supports all OBD2 protocols. They include all universal modes and some brand-specific modes like Diag-H by Honda and UART by GM.

As such, the device gives you access to the engine (ECU), transmission, ABS, SRS, and all the major systems. You can read and clear their codes.

Therefore, it allows you to turn off the Check Engine Light (MIL) and other warning lights.

Advanced Diagnostics

Users can use Autel MK808BT for EPB service, mileage/interval service reset, oil service reset, BMS service, and IMMO (immobilizer).

Besides pulling and clearing codes, you can use this Autel scanner for EPB service, mileage/interval service reset, oil service reset, BMS service, and IMMO (immobilizer).

EPB service checks to ensure that your electronic brake system works efficiently. When you reset interval or mileage, the service light turns off. Similarly, resetting the oil service turns off the oil light.

While BMS service gives you the ability to register a new battery and monitor its current, the IMMO function allows you to disable lost keys and program new ones.

If you are a mechanic, repairer, or DIY enthusiast, you will need all those functions.

This scanner does deliver on all saves for IMMO. You can’t use it to program new keys.

Professional Functions

The Autel MaxiCOM MK808BT supports forced DPF regeneration, TPMS sensor relearning, SAS reset, and relearning of the new parking brake pad. These are professional-level functions that experienced auto technicians, and fully-fledged auto shops need.

Even so, the scanner still lacks in this respect. It doesn’t support actuation, coding, and adaptation. So while it’s possible to use it professionally, you may even need a better device with more professional functions.

Will the Autel MaxiCOM MK808BT work on your vehicle? On paper, if the car is OBD2 compliant, it should. In other words, if the vehicle is a 1996 or newer model, the device should connect with its onboard computers and deliver all the basic, advanced and professional functions advertised by Autel.

The reality is a bit different, though. Let me start by saying that you can use the MaxiCOM MK808BT to perform all basic diagnostics (ECU, transmission, ABS, SRS, and any other systems) on all OBD2-compliant cars, light trucks, SUVs, and hybrids that are domestic and foreign.

However, some advanced and professional functions don’t work on certain car brands. For example, it doesn’t do injector tests on some VW and BMW cars. Similarly, TPMS service doesn’t work on some Honda, Hyundai, and Benz cars.
