Why choose klavkarr?

Why use a diagnostic scanner for your Opel?

Connect to the OBD2 port, with no dismantling or specialist mechanical knowledge required.

Plain-English fault codes

Fault codes explained clearly, without technical jargon or a manufacturer-specific software licence.

Updates included

New models and codes are added regularly, with no subscription.

On recent diesel Opel models, common emissions-related fault codes include: P0401 for insufficient EGR flow, P2002 for low diesel particulate filter (DPF) efficiency, or P20EE for low SCR (AdBlue) catalyst efficiency. An OBD2 diagnostic check helps narrow down the cause before any repairs.

Whether you drive a Corsa, Astra, Mokka, Grandland or Crossland, the OBD2 port is usually below the steering wheel. klavkarr connects directly to it, with no dismantling or specialist tools required.
