2016 Range Rover sport - diesel fault ; Help needed

I have this Range Rover sport but diesel and it keep showing codes on the nox monitoring system and SCR.

Please I need help on how to tackle this issue. Attached is a screen picture of the faults codes been read.. I don’t know if it is the sensor being faulty or the particulate filter, please need guides as to what to check, am not that diesel specialist..

Thanks

There is a bulletin out for some of the codes. I attached a copy, Please follow it closely and report on outcome.

also, please see the video for a explanation of the system, and make sure system is full of fluid.

I have carried out the fault tracing base on the info you have given and tried to performed the special functions in the bulletin you shared with me, I did made some videos which you can download via this web link below, with still permanent dtc’s existing..

So advise me what must be done next...

Thank you for your support.. and also to everyone who read my thread.

is the system full of fluid??

did you perform the test drive as indicated in the TSB??

The system is of it level yet nothing works, system was all drained and refilled.

Test drive was performed too

ok,... please take a picture of the engine ECU info, and compare to these sw numbers.

L405 GK52­12K532­PRJ
L494 GK62­12K532­PRJ

also, I would remove the def injector and inspect it, if you can activate it with the scan tool and verify it is injecting fluid properly in the exhaust,

compare known good tips by the picture,

inspect and make sure there are no exhaust leaks.

clear all faults, then perform a drive cycle to complete the SCR monitor.

1. Idle the engine for 10 minutes.
2. Run the vehicle at speeds between 40 ­ 60 mph, for a minimum of 5 minutes avoiding high accelerations.
3. Cruise at 40 mph for around 4 ­ 5 minutes, then slowly accelerate to 60 mph, using a steady accelerator pedal input.
4. Pull over safely and conveniently and switch off the engine until the red P symbol is no longer present on the Instrument Cluster.
5. Start the engine and repeat steps 2 and 3 and return to Retailer.

When the 'reset selective catalyst reduction quality' monitor has been successfully completed , the warning message in the Instrument Cluster (IC) will no longer be displayed. The remaining DTCs (P2BAE/P2BAF) can now be cleared from the PCM

I will get back to you, after applying this info you have shared with me.

Thanks for your kind input to this thread
