Which OBD2 diagnostic tool is right for your car?

Modern vehicles contain increasing amounts of electronic equipment. Some makes use dozens of control units to process sensor data. Electronics improve safety and comfort and reduce fuel consumption and emissions, but they also make faults harder to trace.

An effective diagnostic tool helps you identify the source of a fault more quickly. The scanner provides a fault code that guides your investigation towards the affected component or system.

A klavkarr can pay for itself after just one use compared with a diagnostic at a garage!

How do I know whether my car is compatible?

OBD requirements apply to modern vehicles, with dates that vary by market and vehicle type.

An OBD2 port in your vehicle

The 16-pin connector is required on vehicles covered by OBD2/EOBD regulations. It is usually located within 60 cm of the steering wheel.

Petrol 2001 - Diesel 2004 (European market)

From these years, EOBD regulations require engine diagnostics on most European-market passenger cars, so the vast majority are compatible.

Choose the right scanner for the warning light

Engine, DPF, AdBlue and oil service: klavkarr 210. ABS, ESP and airbags: klavkarr 310. Use the compatibility check above to confirm coverage.
