climate control

[cookie9561]

i notice when i have climate control on automatic and i change the temp settings the blower fan does not increase or decrease fan speed,i have to do it manually,shouldnt this be automatic,be grateful for any thoughts on it

It will only do it if the temperature difference request is significant enough to require the assistance of the fan. This would normally happen when cooling in summer.

As above, but you could try "Auto" on the other fan mode to see if that makes any difference.
If you push "Auto" once the LED on the left hand corner of the switch lights up and a small fan symbol appears on the display next to the word "Auto"
If you push "Auto" again the LED on the right hand corner of the switch lights up and a larger fan symbol appears on the display next to the word "Auto"

i can adjust temp from 16 degrees to 29 and fan speed does not increase from 2 lights,dont have any fan symbols that i can see,fan speed stays same until i move it to low or hi then fan comes on full blast as it should

The fan symbol I an talking about appears on the RCD/RNS display when you push the "Auto" button. It appears right next to the word "Auto" on the display and it has 2 distinct sizes depending on how many times the "Auto" button is pressed.

cant see any fan sign rcd display,just has my media radio etc,i have got fan speed adjusting now tho,it goes to to 4 bars on speed when i adjust enough,only goes on full when i set it low

When I change any of my climate settings my RCD510 display changes over for a short time and displays all the climate control information

my one doesnt do that,dont know if i have a different version,anyway many thanks to you and mark v for your help

[Cuprabob]

No problem mate, possibly you have the version with the digital temp display above each temp control knob, which I believe doesn't display info on RCD display

One thing to remember with the Climatronic system is that if the car is cold and you call for heat it will not ramp up the fan until there is heat available - you can reduce the time it takes for this to happen on the TDI models by pressing the a/c button (I know it sounds back to front) - in cooler external temperatures it switches on an auxiliary electric heating circuit which gets warmth in to the cabin in a minute or two even on very cold mornings.... this is the argument for always aswitching on a/c at the start of every journey no matter if its winter or summer. The only time is not going to make much difference is the few times when the requested cabin temperature, the actual cabin temperature and the external temperature are are very close to one another.

Good advice - I always tend to just leave the A/C on in my car and it made literally no difference on MPG (in a Megane III). Can imagine the Rocco will be similar when it finally arrives.
