Data confidence65%
The control module detected a fault associated with the Software Incompatibility With Reductant Control Module circuit or function; the stored code identifies the affected component rather than a single failure mode.
Symptoms
MIL or SCR/AdBlue warning illuminated
Possible start-count-down or torque limitation on some applications
Possible causes
Reductant quality or level fault
Dosing valve or supply module fault
NOx sensor fault
Frozen or crystallized reductant lines
Wiring or connector fault
Recommended checks
Read NOx sensor values and dosing system status
Check reductant level and quality data
Inspect dosing valve, lines and heater operation
Check wiring and connectors of the SCR components
Check for OEM technical bulletins and software updates
Generic SAE-standard code: same meaning on every make.

Frequently asked questions about U030F
What does U030F mean?
Software Incompatibility With Reductant Control Module. The control module detected a fault associated with the Software Incompatibility With Reductant Control Module circuit or function; the stored code identifies the affected component rather than a single failure mode.
Is U030F generic or manufacturer-specific?
U030F is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.
Can TuningBot remove U030F at file level?
Not guaranteed. Powertrain (P) codes can be reliably disabled in the ECU calibration, but body, chassis and network codes depend on the specific control unit and how the fault is implemented - some can be handled, some cannot. Ask for a quote and our engineers will check your file and tell you, free of charge, whether U030F is removable in your case.
