Still not fixed, so I have some more questions for others with the climate control fitted. I seem to have lost my original post.
The story so far:
- The cabin slowly cools during a long journey. It takes me about an hour to get to work, I start at about 22deg, and I'm generally at 26-27 maintaining the same temperature when I arrive.
- TSB LA412-003 (foam 'sock') fitted. Seemed to slow down the rate of cooling, but didn't fix the problem
- TSB LA412-001 (reload climate software). No change
The reason for my extra post is that I've started noticing some strange stuff. An example - when I'm belting round a right hand corner, or a roundabout, the cabin immediately gets hotter, like there's a loose paddle in the system that suddenly switches to the hot side. Left hand bends don't seem to affect the temperature.
Also, I've noticed that nothing ever comes out of the vents on the back of the centre console. Are these meant to do something, or are they for decoration only? FYI, I don't have the rear aircon option.
Climate control seems to be more consistent with other people in the car. Anyone else noticed anything like this?
It's going back to Guy Salmon in Stockport the week after next for the park brake, I'd love to be able to give John some pointers what to look at or some proper symptoms.
Help!

The rears should put out air. Check they are open first, if they are and no air comming out there is a problem somewhere.“There are only three sports: bullfighting, motor racing, and mountaineering; all the rest are merely gamesâ€

first thing to do is to check that the system operates as expected manually, not only air distribution but temperature and fan speed, secondly - assuming all is OK, run a self-test on the ATCM
"The motor and flap operation can be checked using the on-board distribution motor self-test function.
The self-test can be initiated by pressing and holding the ECON and RECIRC buttons while turning the ignition switch to the ON position.
The control module will then compare the current motor position with the values stored in the module and will indicate an error by flashing the ECON LED (light emitting diode).
If there are no errors, the LED will go out and the system will function normally.
To confirm that there are no errors, turn the ignition switch to the OFF position, then back to the ON position.
Observe the operation of the programmed defrost LED.
If there are errors present, the programmed defrost LED will flash and the system will attempt to calibrate itself."
note that this will only test the motors, and won't confirm they are actually connecte to the flaps.... if the fault is reproduceable, get the service manager to drive the vehicle with you in it to confirm the problem - although the issue of cooling below threshold sounds like a disconnected pipe, seperate to the distribution flap problem
I take it this information comes from having a proper subscription to GTR? I think I might have to look into doing that myself.

I've noticed this 'hotter when taking bends' effect in many big cars. I think its all the cold air in the bottom half of the car (heavier than warm) sloshing to the side of the car which is on the outside of the bend, just as if were water. This displaces the warm air sending it over to the driver's side.
In my RR I used to get the opposite. Felt a cold draught across my face when going round roundabouts!
BTW Might get to my 400 tonight!Back in the game!

I've just tried the Econ and Recirc button press whilst turning the ignition on and the Econ button flashes, so what does this mean ?
I am interested to know as I have always suspected the air distribution to be a bit suspect as on auto it only really blows air to my feet and nowhere else. It does work fine in manual though i.e if I direct the heat using the 3 buttons.
Yes, me too. The econ light flashes. Nothing from the Prog light after restarting, so presumably the self-checks come out alright.

Funny you should mention the issue, I have noticed that I have to increase the temp setting to keep the heat at a comfortable temp. I thought it was something to do with the mild temperatures causing the auto-climate to try and cool the car..!
It's hard to track down exactly whats happening, but over the few weeks I've had the car I often have to increase the temp setting from 20 to 24 to keep it comfortable.
That will please the traditionalists!Back in the game!

I find that in auto it only uses the feet vents to start with then it does open the others after a while (not timed how long)
It must have been set like that as hot rises and so its warming cool air rather than warming warm air.
It was the same in my last one and it does warm up very quick even without the fuel heater helping it.Focus ST500

Mine seems reluctant to send air to the windscreen when in auto, and can be inclined to start fogging up on some days. If I press the button to send air to the windscreen it sends air to it fine - is this normal behavior in full Auto mode, or do I have a problem - have latest software, and had the foam pad put in with the sensor 2 months ago.IE - 05 D3 TDV6 HSE - Zambezi Silver

Mine is the same. Its enhanced, and foamed too. I have been running with the econ button pressed for a while now, and find the temp control seems to better.
Mine is left on 22 degrees all the time. If I have a few bodies on board, or its damp air, then I turn off the econ mode and the temp will need nudging up a bit for comfort.
