# XTOOL D7 vs Autel MK808S Source: https://codeandclear.com/blog/xtool-d7-vs-autel-mk808s Published: 2026-10-09 Publisher: Code & Clear **Short answer:** On listing facts the XTOOL D7S offers more for slightly less: ECU coding, 4000+ active tests, 39 resets including crankshaft relearn, CAN FD, DoIP and 3 years of software updates. The Autel MK808S lists bidirectional tests, 28+ services and FCA and Renault gateway access, but no coding or update term. Pick the MK808S mainly if you prefer Autel's interface or its coverage fits your vehicles better. The XTOOL D7 and the Autel MaxiCOM MK808S are two common choices for a first bidirectional scan tool. The original D7 is not among the products in our guides, so this page compares the closest listed model, the **XTOOL D7S**, which is the current version of the D7 line, with the **Autel MK808S**. All specs come from the Amazon listing text for each tool. Where a listing says nothing, we write Not stated. ## Spec comparison from the listings Specs come only from each listing. Prices are listing prices at the time of writing and change often, so check the current price before you buy. Both tools are tablet-style bidirectional scanners aimed at advanced DIYers and small shops. The differences show up in coding, protocol support, the number of listed resets and the stated update term. | Spec | XTOOL D7S | Autel MK808S | | --- | --- | --- | | Listing price | $420.00 | $449.00 | | All-system diagnostics | Yes, OE-level | Yes, 1996-2026 vehicles | | Active tests | 4000+ | OE-level (count not stated) | | Service functions | 39 resets incl. crankshaft relearn | 28+ | | ECU coding | Online and offline, plus PMI | Not stated | | CAN FD and DoIP | Yes | Not stated | | Secure gateway | FCA AutoAuth | FCA AutoAuth, Renault SGW | | Vehicle coverage | Not stated | 150+ makes | | Live data | 8-in-1 graphing, AutoVIN, AI-assisted diagnostics | All systems live data | | Software updates | 3 years free | Not stated | | Hardware | Kickstand | Android 11, 4-core 1.8GHz | XTOOL D7S vs Autel MK808S (listing facts only) ## Diagnostics and active tests Both tools scan all available systems, read and clear codes and show live data. The **D7S** listing describes OE-level diagnostics for engine, transmission, ABS, SRS, BCM, TPMS, steering and battery, AutoVIN and Auto Scan, AI-assisted diagnostics and 8-in-1 live data graphing. The **MK808S** listing describes all-system scans on 1996 to 2026 cars covering modules such as PCM, ECM, EPS, BCM and TPMS. Both list bidirectional control. The D7S states 4000+ active tests. The MK808S describes OE-level active tests on ABS, windows, doors, solenoid valves, wipers and headlights without a count. Test counts are maker figures, so check coverage for your exact vehicle. Our explainer on [bidirectional scan tools](https://codeandclear.com/blog/what-is-a-bidirectional-scan-tool) shows how active tests help you confirm a fault before buying parts. 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. ## Resets, coding and protocols The D7S lists 39 resets, including crankshaft relearn, which some vehicles need after crankshaft sensor, engine or PCM work. The MK808S lists 28+ services such as oil reset and SAS. For routine maintenance either one covers the common jobs; the D7S lists more. The D7S also lists online and offline ECU coding and PMI. The MK808S listing does not mention coding. If you want to turn hidden features on or adapt replacement modules on supported makes, the D7S is the one that states it. See [what ECU coding is](https://codeandclear.com/blog/what-is-ecu-coding) before you count on it. The D7S lists CAN FD for newer GM vehicles and DoIP for BMW, Jaguar, Land Rover and Volvo. The MK808S listing does not mention either protocol. That can matter if you own or work on recent models from those makes. 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. ## Updates and long term cost The D7S listing states 3 years of free software updates. The MK808S listing mentions subscription renewal inquiries in its support section but does not state an update term. Ask the seller or check Autel's site for the current terms before you buy, and read [our guide to updates and subscriptions](https://codeandclear.com/blog/scan-tool-updates-and-subscriptions) to understand what keeps working when updates end. ## Who should buy which For more picks from each brand, see the [XTOOL scanner guide](https://codeandclear.com/best/best-xtool-scanner) and the [Autel scanner guide](https://codeandclear.com/best/best-autel-scanner). - You want ECU coding, crankshaft relearn and newer protocols for less: XTOOL D7S - You work on newer GM, BMW, Volvo or Jaguar Land Rover vehicles: XTOOL D7S - You want Renault gateway access stated in the listing: Autel MK808S - You already use Autel tools or prefer its interface: Autel MK808S [See our bidirectional scan tool picks](https://codeandclear.com/best/best-bidirectional-scan-tool) ## Frequently asked questions **Is the XTOOL D7 the same as the D7S?** The D7S is a newer version of the D7 line. The original D7 is not in our guides, so we compared the D7S listing. XTOOL also sells wireless versions such as the D7W and D7BT. **Can the Autel MK808S do ECU coding?** Its listing does not mention coding. Autel tools that list coding cost more, such as the MaxiSys MS906 PRO. **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. **Is either tool good for a beginner?** Yes, if you are willing to learn. Start with reading codes, freeze frame and live data, and move on to active tests and coding once you understand what each function changes.
