ADBLUE TANK

[walter]

Can anyone please tell me if my Berlingo K9 2020 van as a drain plug on the adblue tank don't do a lot of miles and would like to drain it off and fill up with fresh thanks for any help.

Yes they do. On the tank side that is facing toward the engine bay, there is a mount and to the right of this is the small drain cap.

Somewhere in the area circled, but don't ask me how to remove it:

There is a little torx screw (T-20 from memory) holding the plug in unscrew this first then the drain plug just twists & pulls out.
Id recommend leaving the adblue filler cap on when your remove the plug as once you take the filler cap off it starts to drain out fast
