The best advise I can give anyone driving a JLR product with adblue is to only ever underfill the system. Meaning if your car requests 10ltrs only put in 5... There is an inherent issue with Adblue systems over pressurising and blowing the injectors to bits... Mainly on the smaller engines but seams good practice to not fully fill any of them...

That’s really interesting to know…. At my last service I made them top up completely. Won’t do that again. Filters are in fact so good that in certain circumstances, when the ambient air is already polluted, a diesel car will tend to extract more particles from the air than it emits. Emissions Analytics worked with........etc etc

He who dies with the most toys wins...

No sir that’s not what I’d suggest at all… 👍
