ThinkScan 662 Review | Real Results
I tested the ThinkCar ThinkScan 662 on three cars: Golf 2006, Alfa Romeo 147, and old Passat 1999. This is their cheapest bi-directional scanner that still gives you real actuator tests and 12 service resets. It is only a 4-system tool, but for these four systems it works like a full scanner.

Thinkcar Thinkscan 662
Thinkscan 662 is a 4-system scanner: engine, ABS, airbag, transmission.
Not full-system. Not a tablet. But it has real bi-directional tests and 12 service resets in my testing, which is unusual in this cheap category.
Best for people who want something stronger than a basic code reader but don’t want subscriptions or smartphone apps. Weakness is obvious: you cannot access body, comfort, infotainment, or other modules.

What This Tool Actually Is
ThinkScan 662 is a budget 4-system diagnostic tool with real actuator tests.
Same software family as DF65.
Good step between a basic reader and full professional scanner.

Test Results on Real Cars

I tested it on real cars.
Cars used:
• VW Golf 2006
• Alfa Romeo 147
• VW Passat 1999
• (Plus short tests on Mazda/Toyota/Honda in past videos)
What worked

On all three test cars the scanner connected.
Engine, ABS, airbag, transmission (if automatic) work fine.
Live data loads fast. About 300 values on VW engine.
Bi-di tests worked in ABS, engine, SRS.
What failed
VIN auto-scan does not work on older cars.
Some older VAG cars use sequential bi-directional tests, not individual components.
This is not scanner fault — this is how the ECU works.
Old Alfa scanning is slow because it tries multiple ECU types.
Scan speed

4-system scan is quick.
Full Alfa scan is long but Alfa is always slow.
App / tool behavior
No crashes.
Stable.
Menu simple.
Coding
None.
Not available in my testing.
Slow features
Alfa module detection is slow.
VIN scan is kinda of useless on old cars but that goes for different scan tool brands as well.
Manufacturer Specs vs Real Testing
| Area | Manufacturer Claim | What I Saw in Testing |
|---|---|---|
| Module coverage | 4 systems | 4 systems only |
| Bi-directional | Yes | Works in all 4 systems |
| Service resets | 12 | I saw 12 working |
| Updates | Lifetime | Lifetime via Wi-Fi |
| Scan speed | Fast | Fast on VW, slow on Alfa |
| Coding | No | None available |
| Live data | Multi-graph | Very good, up to 4 graphs |
Hardware / Software / Plans / Internet Dependency

Wired unit (USB-OBD).
Always charging while in use.
Better than Bluetooth for workshop use.
Software is simple.
Menus are clear.
Reports look clean.
Plans:
No plans.
No subscriptions.
Lifetime updates included.
Internet:
Needed only for updates.
Diagnostics work offline.
Credits:
No credits.
Risk:
No coding, so safe.
Still, wrong bi-di tests can damage weak components.
Supported Service Resets
I saw 12 resets in my testing.
- Airbag reset
- Anti-theft/Key matching
- Battery matching
- Brake-pad reset
- DPF regeneration
- Electronic throttle adaptation
- Gearbox learning
- Injector coding
- Oil reset
- Steering angle reset
- TPMS reset
On VAG: basic resets only.
No coding.
No adaptations.
On BMW/Toyota/Lexus: only simple resets. No deep service menus.
On other brands: varies heavily.
For heavy multi-brand service work: Kingbolen K7, Mucar VO7, Thinkcar tablets are much stronger.
Supported Languages
Many languages available.
But translations are basic.
English is safest.
Users often check Google/forums for deeper meaning.
Comparison Section

1) ThinkScan 662 vs Topdon ArtiDiag 600 Lite

ArtiDiag 600 Lite is a full-system scanner.
ThinkScan 662 is a 4-system scanner.
Both now have free lifetime updates depending on seller, but ThinkScan is still more consistent here.
Big difference:
ArtiDiag does not have bi-directional tests.
ThinkScan does.
Comparison Table

| Service resets | 12 | Some resets |
| Updates | Lifetime | Lifetime (varies by store) |
| Live data | Strong | Strong |
| Coding | No | No |
| Value | Very good | Good, but less features for same price |
Conclusion:
ThinkScan wins if you want bi-directional tests.
ArtiDiag wins if you need full-system access.
2) ThinkScan 662 vs Dollarfix DF65

Thinkscan 662 is same software/hardware family as Dollarfix DF65.
Same software family.
Same 4-system limitation.
Same bi-directional behavior.
ThinkScan has 2–3 more service resets in my testing.
Otherwise identical.
Comparison Table
| Feature | ThinkScan 662 | DF65 |
|---|---|---|
| System access | 4 systems | 4 systems |
| Bi-directional | Yes | Yes |
| Service resets | 12 | Slightly fewer |
| Coding | No | No |

Conclusion:
ThinkScan is a slightly better version of the same tool.
3) ThinkScan 662 vs Mucar 682

Mucar 682 is a big upgrade.
Full-system access.
Bi-di tests in all systems.
More service resets.
Better long-term value if you want one scanner for everything.
ThinkScan is cheaper but limited.
Comparison Table
| Feature | ThinkScan 662 | Mucar 682 |
|---|---|---|
| System access | 4 systems | Full-system |
| Bi-di tests | Yes | Yes, wider coverage |
| Service resets | 12 | Many more |
| Updates | Lifetime | Lifetime |
| Live data | Good | Full-system live data |
| Coding | No | No |
| Value | Best for cheap 4-system | Best for full-system budget tool |
Conclusion:
If you can pay more, Mucar 682 is much better.
Final Verdict
ThinkScan 662 is great if you want cheap bi-directional tests and service resets but you don’t need full-system access.
It works well on old cars too.
If you want full diagnostics, look at Mucar 682.
If you want the same tool cheaper, DF65 is close.
If you want a tool with full-system but no bi-di, ArtiDiag 600 Lite is an option.
