the most important thing on the new climate control are the "separated" switches for seat heating. The air con doesn't come on every time you put your seat heating on..

 

I don't quite understand this comment, but I have a 2010 A5 with dual front and 3rd rear climate control, and my front control panel looks almost identical to that except screen is red, not black and white and possibly a botton to the right of the drivers nob.

so probably not useful in using this as a comparison to FL and Pre-FL.

 

I'm also looking to do this upgrade does any body know?

 

I believe it's plug and play but I think its component protected.

I'll have mine spare soon as I'm installing ventilated seats which require further buttons.

 

What does component protected mean ?

 

If my understanding of what you're talking about is correct, there's a geezer selling a climate control unit in the For Sale section.

 

IIRC new cars have three settings for heated seats, whereas older pre-facelift ones have six.

Are the outputs of the two units compatible with each other, or is there a risk that the new unit won't properly control an old heated seat?

 

I've fitted facelift seats into a pre-facelift car and the heated seats worked fine on all 6 settings.

 

Did you install the new facelift climate control ?

 

The climate control on preFL cars is a small strip unit, however on FL cars looking a the following link it looks a different fitment:-

GENUINE AUDI A4 A5 2012 2013 Heater Climate Control Unit Switch Facelift Heated | eBay

 

3G and 3G plus are interchangeable, as are the button panel on the centre console.

The dash is the same, how different can it be?

Not saying it is the same just not sure where it can differ.

 

ok reading the www, it appears to be component protected.

I have bought one to try it out as Im curious so will come back and let you know my findings when it arrives.:thumbsup:

 

ok received, can the knobs be swapped over does anyone know. I dont want to try and prize these off if they wont move.

JB:thumbsup:

 

Did the Facelift climate control work for you ?

 

Hi

The connectors are all the same, plugged it in and it all lit up ok but then went into component protection, the on/off button started flashing red. Put the old one back in, all ok.

Same size, same connectors, just needs component protection removing. I found a place in Manchester that can remove this so will try them, otherwise get Audi to do it at some point.

:thumbsup:

 

I'll be interested to hear how much functionality you get. At the time I did my audio upgrade Ben advised me against doing the CC as only get 3 heated seat settings, can't remember what else he said also. Looking forward to reading your testing :thumbsup:

 

I haven't got the heated seats so cant test this function but will let you know how I get on.

:thumbsup:

 

What is this component protection and what is its purpose?

 

Its to protect certain parts from are cars. So people can't just steal them and put them on other cars , From what I heard.

 

Thanks digzz, makes sense but also annoying for those genuinely wanting to change their units!

 

Yep...This is kinda new to me also ....as my Audi a3 8p never had any type of protection of the units like this.

Boydie Have you got your S5 as of yet ?

 

Old A3 like TT and R8 doesn't have integrated network of components, it's all RNSE head unit based, that's why it has no component protection, it's older tech.

The A5 electronics is much more advanced, but ut does make retrofitting more awkward,

 

@Boydie

I see in your description your car hovers on a regular basis?

How did you achieve this, I want it too!

I've just done a few test's with VCD with my old climate control unit and this new one.

As you can see it not only throws up the component protection which we know about but it throws up more errors to do with functionality of the unit.

This kinda feels like the Audi a3 8p Facelift Chrome Climate Control With the issue with air circulation flaps.

Plus the fact that the buttons are in different places.

I might do a DIY and see if I can change the chrome knobs and the Black LCD and swap the round with the old unit.

 

Did anybody have any joy with getting the facelift climate control unit to work on a prefacelift car?

 

from more research I've done, I'm pretty certain it's a non starter.

 

i've done this myself, had to get the protection component removed, it's powering up now and everything seem to show signs of functions but there's no response on the heater or ac. the guy that fitted it for me said the module will have to be changed and he's next available in about a week and a half so fingers crosses.
the only buttons that are working is the heated seats and the rear shield ice defroster

 

I'm in the same boat.

It appears to regulate/control the temperature, but is unable to control the fan speed.

Could be a coding or adaptation channel setting, but without any controller coding helper or channel mapping, and a longer coding value than the pre FL part I'm a little in the dark as to if/when I'll be able to get this working...

 

As Adamantium has said above I'm also pretty sure it's a non starter. From the research I've done in the past, it seems like a new central electrics module is needed which is not possible to fit on pre-facelift manual cars.

 

With all the trouble i hear in here,I think I can live with what it came in the first place...

 

I've come to the same conclusion also. I've even tried to replace the faceplate with big issues as the buttons are in different places back and front.

 

I got good news guys :2thumbsup:


I've managed to get the facelift climate control to work .


All that's needed is coding and protection component taken off.
