D4 aircon slow to cool

[Discojoe]

Helle fellow LR enthusiasts.

I've searched around and can't find an answer. My 2010 D4 aircon is very slow to get cold, it's usually when I accelerate to over 60 that it kicks in. I live in the tropics so the outside temp is mostly over 30 and I have the settings on either 16 or Lo. At start and for a few minutes after the air just feels like ambient air temp. Any suggestions as to why it may be doing this?

Thats odd mine is an MY13 and i just leave it on 23 usually with the auto setting on and it cools the whole car very quickly on a hot day and keeps it there all day, maybe need a regass not sure.

Not being a Disco owner, I can offer no helpful advice other than you might need this aircon upgrade:

Check the cabin filter, it may be clogged with dust etc.
