**Short answer:** On listing facts the Topdon ArtiDiag Pro gives more for less: it lists bidirectional control, ECU coding on makes such as VW, Audi and Mercedes-Benz, and 35+ services at a lower price than the Autel MK808S. The MK808S lists bidirectional tests, 28+ services, 150+ makes and FCA and Renault gateway access, but no coding. Choose the Autel if you prefer its interface or need its listed coverage.

The Topdon ArtiDiag Pro and the Autel MaxiCOM MK808S are both bidirectional tablets aimed at home mechanics who have outgrown a basic code reader. They sit close in price, but their listings describe different strengths. This page compares them on the facts each Amazon listing states. Where a listing leaves something out, we write Not stated rather than guess.

## Spec comparison from the listings

Specs come only from each listing. Prices are listing prices at the time of writing and change often.

The Topdon listing gives fewer hardware details than the Autel listing, while the Autel listing gives fewer details on coding and updates. Keep that in mind when you read the Not stated rows: they mean the listing is silent, not that the tool lacks the feature.

| Spec | Topdon ArtiDiag Pro | Autel MK808S |
| --- | --- | --- |
| Listing price | $379.99 | $449.00 |
| Bidirectional control | Yes, tests on individual actuators | Yes, OE-level active tests |
| Service functions | 35+ | 28+ |
| ECU coding | Yes, VW, Audi, Skoda, Seat, Benz and more | Not stated |
| Secure gateway | FCA AutoAuth and Renault, 2017 and later | FCA AutoAuth, Renault SGW |
| Vehicle coverage | Not stated | 150+ makes, 1996-2026 |
| Operating system and CPU | Not stated | Android 11, 4-core 1.8GHz |

Topdon ArtiDiag Pro vs Autel MK808S (listing facts only)

## Diagnostics and bidirectional tests

The **Autel MK808S** listing describes all-system scans on 1996 to 2026 cars, covering modules such as PCM, ECM, EPS, BCM and TPMS, with code reading, ECU information and live data. It describes active tests on ABS, windows, door locks, solenoid valves, wipers and headlights.

The **Topdon ArtiDiag Pro** listing describes bidirectional control that runs targeted tests on individual actuators so you can confirm a fault before replacing parts. Both tools let you command parts rather than only read data. See [what a bidirectional scan tool is](https://codeandclear.com/blog/what-is-a-bidirectional-scan-tool) for typical tests, and check each maker's coverage list for the tests on your vehicle.

Note: Active tests move real parts. Keep hands, tools and loose clothing clear of fans, belts, wipers and windows, and follow the conditions the tool shows before each test.

## Service functions and ECU coding

The ArtiDiag Pro lists 35+ service functions, with oil reset and EPB among those named. The MK808S lists 28+ services, including oil reset and SAS. Both cover the routine resets most home mechanics need, and the Topdon lists more.

The biggest difference is coding. The ArtiDiag Pro listing states ECU coding on makes such as VW, Audi, Skoda, Seat and Mercedes-Benz, to turn on hidden features or turn off unwanted ones. The MK808S listing does not mention coding. If you plan to code, read [what ECU coding is](https://codeandclear.com/blog/what-is-ecu-coding) and check that the function you want is listed for your exact model. Our [ECU coding tool guide](https://codeandclear.com/best/best-scan-tool-with-ecu-coding) covers more options.

Note: Coding changes how a module behaves. Back up the original settings when the tool offers it, keep the battery voltage stable with a maintainer, and if you are unsure, leave coding to a professional.

## Gateway access, adapters and updates

Both listings state FCA AutoAuth for secure gateway access on newer Chrysler, Dodge, Jeep and Fiat vehicles, and both mention Renault. Neither listing compared here mentions CAN FD or DoIP, so if you work on newer GM or BMW models, confirm protocol support with the seller.

The Topdon listing notes that the Chrysler 12+8 and BMW-20 adapters are no longer in the package after a product update. Some older vehicles, including some older Chrysler and BMW models, use non-standard diagnostic connectors, so owners of those cars may need to buy an adapter separately. Neither listing states an update term. Check the current terms with Topdon and Autel, and see [scan tool updates and subscriptions](https://codeandclear.com/blog/scan-tool-updates-and-subscriptions).

## Frequently asked questions

**Is the Topdon ArtiDiag Pro better than the Autel MK808S?** On listing facts it offers more: ECU coding and 35+ services at a lower price. The MK808S lists more detail on coverage and hardware. Choose based on coding needs and the makes you work on.

**Can the Autel MK808S do ECU coding?** Its listing does not mention coding. Autel tools that list coding, such as the MaxiSys MS906 PRO, cost more.

**Do updates cost extra?** That depends on the exact listing and the maker's current terms, which change. Some listings state a free update period; others only mention subscription renewal. Check the listing and the maker's update policy before you buy, and see [scan tool updates and subscriptions](https://codeandclear.com/blog/scan-tool-updates-and-subscriptions) for what stops working when updates lapse.

**Do I need the missing adapters for the Topdon?** Only if your vehicle uses a non-standard diagnostic connector, such as some older Chrysler and BMW models. Vehicles that use the standard 16-pin OBD2 port do not need them; see [where the OBD2 port is](https://codeandclear.com/blog/where-is-the-obd2-port) if you are not sure.
