Compatibility & Legal Notice

Not every function is available for every TCU, software version or vehicle. Compatibility must be confirmed from the original file and controller identification. Diagnostic trouble codes normally indicate an underlying electrical, mechanical, hydraulic, sensor, actuator or control-system problem and should be properly diagnosed and repaired rather than concealed. Any motorsport or off-road-only calibration service must comply with applicable local laws and vehicle regulations.
