Hi Guys,

Am retrofitting heated seats and have replaced the climate control with the correct one for my car. The donor car had rear climate control fitted.

My dealer has removed CP but doesn't know (or can't) do the correct coding.

Does anyone have their coding for Address 08 Auto HVAC (and mind sharing) for a UK 3.0tdi RHD with heated front seats and No rear climate control unit?

Thanks,

Dave:lol:

Coding air conditioner Climatronic control unit -J255



Table for overall coding

J The overall coding comprises the sum total of the individual codes (code number "1" code number "2" plus code number "3".

Code "1"

J Coding of number of engine cylinders, engine type and country variant (code "1" table)

J Example for a vehicle with 8-cyl. petrol engine for Rest of the World (e.g. Germany) "8"

Code "2"

J Coding for body variant (body shape, left/right-hand drive) and specific

optional extras (code "2" table)

J Example for an Audi Q7 (Saloon) with left-hand drive and optional

"auxiliary heater" "2048".

Code "3"

J Coding of method of fuel injection and optional extras currently not yet or

not all offered (introduction pending) (code "3" table)

J Example for a vehicle with FSI engine without other optional extras "1"

Example of overall code

J Overall coding for a Saloon with left-hand drive, a 8-cyl. FSI engine without other optional extras for Rest of the World (e.g. Germany).

J Overall coding "8" (sum of code "1" is "8" plus code "2" is "0" plus code

"3" is "0")



Code "1" of Climatronic control unit -J255

Coding of number of engine cylinders, engine type and country variant (code "1" table).

J Readout = " XXXXXXX0"

Example for a vehicle with 6-cyl. petrol engine for Rest of the World (e.g. Germany) "00000110"

Code "1" table (number of engine cylinders, engine type and country variant)

Readout = " XXXXXXX0"

Blank (no allocation, code number "0")

Readout = " XXXX0100"

4-cyl. engine (code "4")

Readout = " XXXX0110"

6-cyl. engine (code "6")

Readout = " XXXX1000"

8-cyl. engine (code "8")

Readout = " XXXX1010"

10-cyl. engine (code "10")

Readout = " XXXX1100"

12-cyl. engine (code "12")

Readout = " XXX0XXX0"

Petrol engine (code "0")

Readout = " XXX1XXX0"

Diesel engine (code "16")

Country version

Readout = " 000XXXX0"

Rest of the World (code "0")

J Coding for all countries in the world except USA, Japan and China

At present also vehicles for "hot climates" (allocation via production number) and China are coded as Rest of the World.

Readout = " 001XXXX0"

USA (code "32")

J Different to coding for Rest of the World.

The temperature readout in the "Comfort" version is in °F instead of in °C.

The air conditioner is regulated in Summer operation to a somewhat cooler characteristic.

Readout = " 010XXXX0"

Japan (code "64") and China

J Different to coding for Rest of the World

The temperature readout in the "Comfort" version is in °F instead of in °C.

The "recirculated air" function is stored when the ignition is switched off and reactivated when

the ignition is switched on, if it was active when switched off.

Readout = " 011XXXX0"

China (code "96")

J Currently not configured (introduction pending).

Vehicles for China are currently coded as for Japan.

Readout = " 100XXXX0"

Hot climate (code "128")

J Currently not configured (introduction pending).

At present vehicles for "hot climates" (allocation via production number) are coded as Rest of the World.

The following countries and regions will in future be additionally coded as "hot climate": Greece,

Italy, Portugal, Spain, all countries in Asia, America (except USA) and Africa.

With this coding the air conditioner regulation and the radiator fan activation

is controlled by a different characteristic (attuned to the higher ambient temperature).

Readout = " 101XXXX0"

Cold climate (code "160")

J Currently not configured (introduction pending).

At present vehicles for "cold climates" (allocation via production number) are coded as Rest of the World.



Code "2" of Climatronic control unit -J255

Coding of body variant and specific optional extras

J Readout = "XXXXXXXXX"

Example for a Saloon with left-hand drive and optional "auxiliary heater" "00000100".

Code table "2" (body variant and specific optional extras)

Body style

Readout = "XXXXXXX00"

Saloon (code "0")

The Audi Q7 is currently coded as a Saloon.

Readout = "XXXXXXX01"

Avant (code "256")

Left/right-hand drive

This coding is currently preset by the part number and cannot be/must not be changed (differing versions of the Climatronic control unit

for vehicles with left and right-hand drive).

Readout = "XXXXXX0XX"

Vehicle with left-hand drive (code "0").

Readout = "XXXXXX1XX"

Vehicle with right-hand drive (code "1024").

Optional extras

Readout = "XXXXX0XXX"

No auxiliary heater factory fitted (code "0").

Readout = "XXXX1XXX"

Auxiliary heater factory fitted (code "2048").

With code "1" (auxiliary heater fitted) an attempt is made on the convenience system data bus to

exchange information with the additional heater control unit -J364. If the additional heater control unit

-J364 does not respond, a fault is stored in the fault memory.

J At present only a factory fitted auxiliary heater can be coded.

J Retrofitted auxiliary heaters must not at present be connected to the data bus system

and so must not be coded.

Readout = "XXX0XXXX"

No sun roof with solar cells fitted (code "0")

Readout = "XXX1XXXX"

Sun roof with solar cells fitted (code "4096")

With code "1" (sun roof with solar cells fitted), when the ignition off various control motors are activated to set the flaps controlled by them

to the position predetermined for solar operation.

Readout = "XX0XXXXX"

No electric rear roller blind fitted (code "0")

Readout = "XX1XXXXX"

Electric rear roller blind fitted (code "8192")

An electric rear roller blind and thus a rear roller blind button -E385 is fitted.

Readout = "X0XXXXXX"

No air ionisation module -J707 fitted (code "0")

This coding is currently to be entered for all vehicles regardless of specification.

The code "1" is not permitted, introduction of the optional air ionisation module -J707

is pending.

Readout = "0XXXXXXX"

No heated windscreen fitted (code "0")

This coding is currently to be entered for all vehicles regardless of specification.

The code "1" is not permitted, introduction of the heated windscreen -Z2 is

pending.



Code "3" of Climatronic control unit -J255

Coding of method of fuel injection and specific optional extras.

J Readout = "XXXXXXXX".

Example for a vehicle with diesel engine without other optional extras "00000000".

Intended code "3" table (method of fuel injection and specific optional extras)

Optional extras (introduction pending)

Readout = "XXXXXXX0".

No fingerprint driver identification system fitted (fingerprint "one-touch-memory", code number "0")

This coding is currently to be entered for all vehicles regardless of specification.

The code "1" is not permitted. Introduction of the optional "one-touch memory" is pending.

Readout = "XXXXX00X".

No rear Climatronic control unit -E265 fitted (code "0").

Readout = "XXXXX01X".

Rear Climatronic control unit -E265 without activation of heated rear seats fitted (code "131072").

Readout = "XXXXX10X".

Rear Climatronic control unit -E265 with activation of heated rear seats fitted (code "262144").

Readout = "XXXXX10X".

Rear Climatronic control unit -E265 with activation of heated rear seats and seat ventilation fitted (code "393216"). The code "1" is not permitted. Introduction of the "seat ventilation" option is pending.



Type of engine (fuel type) and method of fuel injection

Readout = "XXXX0XXX".

J Diesel engine (TDI = Turbo Diesel Injection) fitted (code "0")

Readout = "XXXX1XXX".

J Petrol engine with petrol direct injection (FSI = Fuel Stratified Injection) fitted (code

"524288").

With code "1" when the engine is cold, for example, the mixture preparation is changed, causing

the radiator fluid to warm up more rapidly and so enhancing the heat output.

With code "1" for example a different transmission ratio (between engine and compressor)

is used to calculate the compressor torque.

Readout = "XXX0XXXX".

Vehicle without special seat type and design (code "0")

This coding is currently entered for all seats regardless of specification.

A code "1" is not permitted. The code will not be defined until introduction of the optional

extras (introduction pending)

Readout = "X00XXXXX".

Vehicle without special rear window type and design (vehicle glazing, code "0")

This coding is currently to be entered for all rear windows (vehicle glazing) regardless of

specification.

A code "XX" is not permitted. The code will not be defined until introduction of the optional

extras (introduction pending)

Readout = "0XXXXXXX".

At present only one code word protocol is configured, so here a "0" must always be entered.

(code "0").

First of all i've changed the rear climate (i haven't retrofit the cables, i'll do it in the short future), using a unit with reference HW: 4L0 919 158 D

When I pushed the heat button it appears an zero (0), but it didn't move when I turn the wheel control.

I've changed the coding of the 08 module from 131096 (131072+ 16 + 8) to 262168 (262144 + 16+ 8) and the rear climate works perfectly (when I turn the wheel control it changes the number of the heat power). Even I have to errors because the climate doesn't find the tempeture of the seat (which is perfectly right)

So i've changed the front climate per a used on with reference ... 4L0 820 043 F. Suddenly It appeared the mistake protection component active (what I expected). This front climate came with the coding 524358 (524288 + 64 + 4 + 2). I've tried to change the coding to 262168 but I coudn't (it let me to change the code to 524312).

I've tried to make a mix between the old front climate and the new one (using the front of the new (buttons and a part of electronics) and the rest os the old, but it doesn't work, when I push the button of the heat power it appears on the MMI the graphic, but the wheel control doesn't work (just like in the rear climate at the beginning) and the module has NO faults.

Any idea???
