Just wondering how often people are filling their AdBlue.

I've recently hit 30k miles and still have 40% left. It has never been topped up from new almost 3 years ago.

I assumed I would be filling it more frequently than this?

My A6 used to drink the stuff - about a litre every 1000 miles.

I never filled my 435D with Ad Blue in the 3.5 years I owned it. Similar mileage.

My 320d barely uses any too.

My 2020 320d has done 17,350 miles and has 40% of its adblue left. Our previous 2019 Audi A4 Avant used 10 litre in 12,000 miles.
