ThinkScan 662 Review | Real Results
Last Updated on April 11, 2026 by Juraj
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.

VIDEO: Iamcarhacker tests Thinkscan 662
In this video I tested thinkscan 662 on 3 different cars.
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.
