Does anyone know if the Gap G4 IID tool can clear emissions codes? I've had a couple of issues with sensors for the DEF quality give me just a couple of hundred KMs before it shuts down the vehicle. I know the DEF quality was correct as it was bought at LR directly, sometimes even filled up by them. I sometimes work further from the dealer than the shut down distance is. I dont want to be caught with my pants down far from civilisation.

Yes, the GAP tool will clear the DEF quality message and resume full range for driving. I also had dealer installed OEM DEF throwing the message and limiting the range on my 2018 Discovery diesel. Driven over 5k miles and no further issues/messages.
