Is this something you could do for me, I amin essex as well (big place I know) but I don't mind travelling. Will the coding allow me to adjust vent positions as I can no longer adjust to feet etc.

I do not have a problem with the fan, I saw some members that they had a problem with the fan that they did it to the maximum, I did not have such a problem

everything worked okay

I have a problem when I return the keys to the minimum, it also blows hot air

This DIY is for pre-LCI cars, the LCI panel is wired slightly different.


Parts needed :-

AC control panel high (IHKA)
Socket housing black, 2 pol 61131378108 x1
Snap in receptacle 61131376204 x2
Universal socket housing uncoded, 26 pol 61136913626 x1
Covering cap blue 61136913644 x1
Solar sensor 64116944017 x1
Bushing contact 61130005199 x4
Universal socket housing, 4 pol 61138380696 x1

Before you start you need determine where the basic panel gets its power.
According to the WDS for cars upto sept/2005 the power is at fuse 26 front fuse box
For cars after sep/2005 the fuse is at fuse 57 rear fuse box, the basic has a 7.5 amp fuse and the high has a 15 amp fuse.
Disconnect the battery before starting.

Dismantle the dashboard :-
Remove the dashboard I-strip, undo the two screws securing the IHKA cover panel, use some slight force to pull panel out of its clips.
Disconnect the two black plugs from the AC panel and put panel to one side.

New pin assignments :-

The basic AC has two plugs :- X01130 12 pins and X18793 18 pins.
The High AC has three plugs :- X01130 12 pins, X13765 2 pins and X1527 26 pins
Carefully prise out the plug from the cover cap of X18793 (18 pins, right hand plug).
Follow this next list to assign the pins to the 26 pin socket contact :-
X18793 X1527
1-----------------1
2 not used
3 ----------------9
4 ----------------8
5 not used
6 ----------------6
7 ----------------7
8 ----------------21
9 not used
10 see explanation for X13765
11 --------------15
12 --------------16
13 --------------18
14 --------------19
15 --------------20
16 --------------14
17 not used
18 See explanation for X13765

For the solar sensor connect :-
Sensor X1527
1--------------- 10
3 ---------------11
4 ---------------12
2 ---------------13

After this is all done, you should have two pins left, these are power and ground (1 red, 1 brown).
Cut off the pins and add around 6 inch of red and brown cable to each, fit the snap in receptacles to the new cables and snap in the red to pin 1 of the 2 pin connector and the brown to pin 2.
Now for the fun part, connect the new connectors to the new high panel and put a 15 amp fuse in to replace the basic 7.5 amp fuse and re-connect the battery.
Switch the car on and the panel should light up, now the car will need coding for SA534 automatic air-conditioning.
