DTC P2BA7-7B: NOx Exceedence - Empty Reagent Tank - Low fluid level: Action

WARNING: This page is about a different car, the 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: A fault clear is NOT sufficient to clear the vehicle 'inducement' system warnings. The 'inducement' warnings automatically clear ONLY upon confirmation of the repair by the vehicle OBD system. The monitoring MUST be executed. The pressure build-up normally occurs when the selective catalyst reduction catalytic converter temperature exceeds 150 °C

Prioritized Checks to Perform
- Check and correct diesel exhaust fluid level
Vehicle Conditions to Enable DTC Logging Strategy
- DEF system pressurized
- On completion of the previous repair actions the following MUST be completed
- Refill DEF tank with at least 5 liters DEF OR if DEF tank already full drain 2 liters of DEF
- Using the Jaguar Land Rover approved diagnostic equipment, run routine - To Reset Selective Catalyst Reduction Start Inhibit
- Drive vehicle at urban speeds approximately 50mph
- Using the Jaguar Land Rover approved diagnostic equipment, clear the Diagnostic Trouble Code(s)
- NOTE: This clears the fault storage from P2BAE/P2BAF
