DEF Fluid Issues

I have a 2016 TD6 Range Rover. Love it, except for DEF. For past two years, in all cycles but one, I get DEF quality message with no-starts after 249 miles. The dealer has struggled to find root cause and do anything but top off and reset. Finally the dealer just replaced the entire tank including injectors. Hopefully that will work, but interested in other ideas?

I'd like to think that if it was at the dealer, they updated all the software. Tons of flash updates for Diesels. I've also noticed that in the exhaust where the SCR Injector is, crystals will form inside the pipe and restrict the spray. If you take the SCR Injector out, the injector will look fine, but if you look down inside the exhaust, you might see a "white tunnel" of crystal formation. If so, that needs cleaned out.

I am in the exact same situation with only a little over 40K on my 2016 RRS. For now the error was simply deleted, but I was alerted it would pop up again soon and the Cat Converter should be replaced, for which they want to charge me over 1,5K Pounds. So, did you find a solution other than replacing the cat converter? Thanks!

it’s to point sadly where I just want to trade it for something more reliable bc I see this is very common with year and model.
any news for you?

i have the same message on the console screen .. was driving, currently 63K mi ... had just topped off tank with fuel, within 15 mins the message came up, got home and topped off tank with 2gals DEF, i've checked the injector, it is clean, started car, nothing coming out, rapped on exhaust pipe, started again, nothing, pulled hose off of injector and started car, no fluid(DEF) coming out, i'm guessing the pump in the tank is not working ? curious, does this DEF pump have a fuse or relay that could be failing ? getting frustrated, on the aside, i'm trying to find a good shop manual, haven't had any luck
