I went to put adblu into the car today. This is the filler cap. It won't turn at all and I'm reluctant to twist it in case I break it. The handbook just says 'turn anti-clockwise'.


What am I missing?

Someone has probably spilt Adblue on the thread before putting the lid back on. When it crystallises, it sticks the lid in place.

It will need some brute force and ignorance to shift it. When it’s off, carefully dry the thread with a lint free cloth before putting the lid back on.

And... make sure your car is on the flat, or pointing up hill. Point it down hill and it’ll airlock like a bast***

You’re welcome. While we’re at it, run it down to a 2,000 mile range remaining and it’ll comfortably take 10 litres.

A 3/8 inch Drive or a 1/2inch drive from a socket set fit the cap to get it off easily. Range Rover LWB HSE L460

I put some white food grease on the thread wire. This way it doesn't clamp and you can easily open the cap next time. 2017 Range Rover Vogue TDV8 silicon silver

All sorted. Yes - it's very ammonia smelling stuff isn't it. Just put about 2.5l of Adblu in. I read somewhere it doesn't keep if the container is opened. Is this correct? 17 MY Corris Grey 4.4 VAB
