Kingbolen S608 TESTED | Owner’s review
Last Updated on April 11, 2026 by Juraj
The Kingbolen S608 is marketed as a mid-tier diagnostic tool with bidirectional control, service resets, and 4-system diagnostics (Engine, Transmission, ABS, SRS). I spent several hours testing it on multiple cars including a VW Touareg, BMW E46, and Nissan to see how well those claims hold up.

What the S608 Actually Is
Kingbolen S608
The Kingbolen S608 is 4-system scanner with real bidirectional tests and service resets, decent for older cars but upgrade to Mucar 682 for full-system.
- 4-system diagnostics with real bidirectional tests
- Service resets for common procedures
- Very good value on older cars where full-system not needed
- Similar platform as ThinkScan 662 and Dollarfix DF65
- Not full-system (only 4 main modules)
- Interface and report layout more basic than higher-end tools
- You recommend upgrading to full-system tools (like Mucar 682) if budget allows

Despite looking like tools from Mucar, ThinkCar, Dollarfix and others, the S608 is not a full-system scanner.
It is a 4-system diagnostic tool that can:
- scan Engine, ABS, Airbag and Transmission
- read & clear fault codes
- view live data with 4-PID graphs
- perform bidirectional tests in supported modules
- carry out 9 core service resets
Extra modules may sometimes show up on certain cars (example: Steering Angle Sensor on BMW E46), but this depends on the vehicle — not the scanner.
Real Test Results
Volkswagen Touareg (Automatic)
Battery voltage was extremely low during testing (around 10V), which caused:
- very slow scanning
- unstable communication
- random fan activation
- scanner showing only 3 out of 4 systems
- inability to read the transmission module
After updating the VW package:
- scanning became slightly better
- but still unstable due to weak car battery
Conclusion for VAG testing:
The S608 works on VW platforms, but low voltage heavily impacts module detection. Expect better results above 12.2V.
BMW E46 (Manual)
This car actually showed the strengths of the S608.
What worked:
✔ Auto-VIN detection
✔ Full system report for 4 modules
✔ Steering Angle Sensor detected as an extra module
✔ Bidirectional tests confirmed
Working bidirectional tests on BMW:
- Fuel pump activation
- Radiator fan activation
Service resets available:
- ABS bleeding
- Battery matching
- Brake pad reset
- DPF regeneration
- Throttle body adaptation
- Gear learning
- Injector coding
- Oil reset
- Steering angle reset
This confirms that S608 isn’t just a code reader — it has real actuation capability inside supported modules.
Nissan Micra K12
VIN detection failed — I had to select manually.
Scanning speed was quick (~30 seconds), but live data was limited and some values appeared as placeholders.
Bidirectional tests:
- Cooling fan actuation worked
- Power balance test triggered injector shutdown clicks (even without engine running)
Limitations:
- ABS module rejected bidirectional commands with “conditions not met”
- Scanner did not explain what conditions were required
This is one of the small weaknesses — the tool should tell you what parameters must be met.
Bidirectional Control: Confirmed
Inside supported modules the S608 can perform:
- actuator tests
- fuel pump activation
- fan activation
- and even power balance tests on Nissan
Test availability varies by car.
Some cars show only 1–2 tests, others more.
Live Data
Live data logging works as expected:
- select individual parameters
- multi-graph mode
- 4-PID graphing
- combined graphs
Note: Live data availability depends on the car.
On Nissan, many values had no labels or only placeholders.
Software & Updates
- Volkswagen software was not pre-installed
- Download required before first use
- Update improved stability
- Interface looks like Launch software
KingBolen claims lifetime free updates, but obviously that can only be verified long-term.
Hardware
✔ Touchscreen + physical buttons
✔ Wired connection (no Bluetooth instability)
✔ Charges directly from OBD port
✖ Can drain weak car batteries faster
Specs:
- 6.2″ screen (1024×600)
- Android 8.1
- 2GB RAM, 32GB storage
- 4150mAh internal battery
- CAN-FD support
- DOIP not supported
- No camera
The wired design is great if you hate charging your scanner often.
Just don’t use it on a borderline-dead battery car because it will pull power from the vehicle.
