If you can pay a kid to do it for you, do it. It's an utter pain in the arse! Ferrari F430 Spider F1

I'm surprised the adblue isn't topped up/drained and replaced at each service. SO many garages charge for screenwash etc., charging to top up adblue would seem to be an easy win for them. 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed

It doesn't last long enough between services and LR will charge you for it if you want them to do it for you in the interim. That said, I get mine for free from my local dealer, they seem to think I'm on some sort of service plan... Ferrari F430 Spider F1

Mines a late 2017 model and the filler is under bonnet. When I get the warning for 1500 miles worth, I normally pickup a 10l can. I can normally get it all in but pushing it.

Its a bit odd if the capacity is double that but I suspect the later tanks are larger right ?
