Now that it is hot, I have noticed one thing in my D5 with the 4-zone A/C.

The driver and both rear seat passengers have the same temp of air blowing (cold). However, The front passenger side blows out noticeably hotter air. After some time, it seems to catch up with the other vents. All dials are set at the same temp and on auto.

Anyone experience that and know its cause?

You are not alone out there.

 

I have noticed that the AC was designed for cool and rainy England.
It is not very good.

 

Try running that a/c in Arizona when it hits 118, not to mention the fact that the poor third row passengers have no vents. I had to buy a $20 usb fan so that my child wouldn't pass out from heat stroke.

 

Dealer does not know how to fix...

They say I can bring it in but the best they could probably do is just diagnose it since there is not a fix for it yet.

 

Sounds like JLR may recommend a new remedy for A/C issues.

 

I was reading on another forum that it was the standard 3 zone climate control that was mucked. If you order the 4 zone it gets better. I'm not sure if that means the one in the 7 seat Lux Pack or just the 4 zone by itself? I have asked for clarification on my 2019 order before we proceed. The wife hauls her UMW ladies all over creation so I need to know they are going to be comfy . . . or else!

 

When I had it at the dealer the other day, they did check it out and found the system was undercharged from the factory (WTF??).

They charged it up and checked for leaks. It has been ice cold all around since.

 

We added the $300 4 zone air to our build. Since it is still upper 90s with high humidity here in Kansas, my salesman did a little research and noticed the Lux they had on the lot with the 4 zone package did work noticeably better than a HSE with the standard 3 zone.
