Autel MaxiCOM MK808S Review
The tablet scanner that reads what the check-engine light is actually saying - on every module, not just the engine.
✓ Pros
- All-system diagnostics, not just engine codes - reads ABS, SRS, transmission, body modules
- Service resets that normally force a shop visit: EPB, oil reset, battery registration, SAS, throttle relearn
- Fast boots and scans on a responsive Android tablet; auto-VIN identifies most cars instantly
- One-year updates included and the hardware supports years of use beyond it
✗ Cons
- Annual software update renewal after year one is the hidden cost of ownership
- Limited bidirectional controls - commanding actuators properly needs the pricier MP808 class
- Menu translations and documentation have rough edges; YouTube fills the manual gap
What it does that cheap dongles cannot
A $25 Bluetooth dongle reads powertrain codes - the P-codes behind the check-engine light - and that is where it stops. The MK808S speaks to every module on the bus: the ABS unit throwing a wheel-speed-sensor code, the airbag light from a seat connector, the transmission module logging a shift fault. Then come the service functions: releasing electronic parking brake calipers for a rear pad change, registering a new AGM battery so the car charges it correctly, resetting steering angle after an alignment. Each of those is a shop visit avoided.
What owners report
Plug into the OBD port, the tablet auto-VINs the car, and a full-system scan lands in a couple of minutes with a report you can save per vehicle - genuinely useful for tracking an intermittent fault or documenting a used-car inspection. The pre-purchase scan is the sleeper feature: ask to plug in before buying any used car, and five minutes tells you if the seller cleared codes hoping you would not look. Owner reports across mixed fleets - domestic, Japanese, German - describe coverage holding up; the deepest German-specific functions want the brand-specialist tools, as always.
Should you buy it?
If you do your own brakes, batteries and sensors on two or more cars, yes - the MK808S earns back its price in one or two avoided diagnostic fees and keeps working after the update sub lapses (you lose new-model coverage, not function). Casual owners who just want to read an occasional engine light should buy a basic Autel handheld for a fraction of the cost. Pro-leaning wrenchers who need active tests should stretch to the MP808 tier instead - know which user you are and this store has the right shelf.
