Why use a diagnostic scanner for your Citroen?
On recent Citroën models, the same warning light can have very different causes: a clogged EGR valve, a deteriorating oxygen sensor or reduced catalytic converter efficiency. klavkarr identifies the specific fault code before repairs, with explanations in English and no manufacturer-specific licence required.
Tested Citroen compatibility
Every listed model has been tested by a user. Our database lists 4,601 car models, covering 12,195 versions and configurations.
Read & clear fault codes
Find out why a warning light is on and clear the code after fixing the fault, without booking an appointment.
Live data
Monitor performance and spot abnormal sensor readings, pressure or emission-control behaviour before a breakdown.
Plug straight in
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.
Codes frequently reported by our Citroën customers include: P0409 for an EGR sensor circuit fault, P0490 for an EGR control circuit high signal, P1351 for a manufacturer-specific fault whose definition must be checked for the vehicle concerned, or P0420 for low catalytic converter efficiency. An OBD2 diagnostic check helps narrow down the cause before any repairs, rather than replacing parts at random.
Whether you drive a C1, C3 (or C3 Picasso), C4, C5 Aircross, Berlingo, DS3 or DS5, the OBD2 port is usually below the steering wheel, near the steering column or behind the fuse box cover. klavkarr connects directly to it, with no dismantling or specialist tools required.
