About This DTC Database

This is TuningBot’s free reference for 17,000+ diagnostic trouble codes: over 9,000 generic OBD-II definitions valid on every make, plus more than 8,000 manufacturer-specific interpretations across 29 manufacturers and groups — including ECU-level records for PSA control units (Bosch, Siemens, Delphi, Continental and more), the same ECUs our engineers calibrate every day.

Every code page covers the meaning, documented symptoms, likely causes and recommended checks, organized by family — P (powertrain), B (body), C (chassis) and U (network). Where a fault can be resolved at file level, the page links the matching TuningBot service, from DTC Removal to DPF, EGR, AdBlue and immobilizer solutions — or you can simply send us your ECU file and let our engineers handle it.
