Aircon query

[PeteB]

Hi All


Just bought a discovery 4 3.0 tdv6 3.00 2011 model with 155k on the clock and noticed the aircon takes 3-4 minutes to start working and then is fine , can someone let me know if that is normal as I have asked the dealer to check as have 3 months warranty and wanted to make sure all ok . My mate has a 2015 model and recons that is normal ?

Nope. Not normal.


I had a MY10 and now own an MY13 .... aircon started within seconds of start-up in both cars.

Certainly not normal but mine has started doing the same thing since they did the inlet manifolds. Seems a common issue with L322's as well and I had the same thing on my VW Multivan at 100,000km. Once it goes it is fine but it is a bit hot while waiting for it to start. I will get mine fixed, probably a new compressor, since fixing the offending valve doesn't always last long without a new compressor from what I have read. It is related to the always on compressor type air con that these cars use.


Maybe Graeme can explain what is going on???

Do you mean for the cold air to come through or for the fan to fire up at all? Our 2010 RRS takes a minute or so for the cold air to come arrive

My MY06 is often that - up to 6 minutes for truly cold air to exit the vents...

Fan kicks in straight away but took 20 mins to get cold whilst car was stationary

I always thought my MY05 took a while to get cold. The added bonus of getting a new engine is that I get my AC re-gassed (I feel compelled to find a positive in anything to do with this engine replacement!!). It will be interesting to see if it performs any better.

I just got mine regassed and inspected to see why it was taking a long time to start. They said it was perfect and then when I picked it up while it was 42 degrees outside, the A/C wouldn't start cooling for over 5 minutes, just blew hot air flat out. It finally started and then worked fine.


Its been good for a week and then on the weekend wouldn't start cooling again for over 3 minutes. After that, fine again.

Yeah that ain't right!

Mine hasnt missed a beat,too new.Always cold straight away.
I have never turned the air off,even in winter,just pic a temp and fan speed.
I recall reading the aircon pump in these are constant flow so if its running may as well have it on.
I could be wrong,happy to be corrected.

Mine is on auto at all times so I don't even have to pick a fan speed or decide where the air goes.

Thanks for that guys. I was thinking about getting mine re-gassed but will hold off for a while now, particularly as the rear wheel bearings need attention immediately.

One thing I have not tried is what the front air con is like when I turn the rear air con off. Currently the rear is always on and set to auto. I have not monitored that but will do so soon to see if there is any change at the front with the rear off.

I leave mine with all the directions turned off,it seems to cycle between them,rarely put the fan speed up to the second choice or direct air to face.
The D2 aircon was very good,this is much better.

Hi Pete,
I only recently just got a D4 2010 TDV6 and the air cond in that was doing much the same, taking forever to cool down.
I got it checked the other day by my mate who is a qualified air con mechanic and he put some gauges on which measured the inlet and outlet gas pressures of the condenser and he suspects my system is over gassed.

but would need to take it to somewhere special to get some of the gas removed? (apparently it is illegal to vent the air con gas into the atmosphere?)
Maybe this is inherent to all D4s?

My good old MY03 D2 air con works awesome! go figure?
