Touch Kimabedienteil

[pimpl1]

Hallo Leute.

Kennt Ihr, oder hat hir eigentlich schon jemand das Touch Klimabedienteil verbaut?
Mich würde Interresieren ob damit alles funktioniert und ob es Plug&Play ist.
Soll angeblich in den neun Asiatischen Modellen verbaut sein.

Ich finde es würde extrem gut zum Radio passen.

Meine letze fehler

Und wo das word hinten steht im loncoding.

Aber immer noch keine hinten display aktiv

[jimmyvw]

Kann jemand mir sagen ob die pin (Belegung) beim neu anders ist ?

@jimmyvw

Warum hast du bei Byte 7 hex 2 und nicht wie normal Hex 01 oder 0000001

[jimmyvw]

Habe es Geändert aber immer noch Fehler Display hinten

[monstermolt]

Hast du hinten den als sub stg drin?

[jimmyvw]

Habe diese hinten

[monstermolt]

Das ist klar, aber kannst du es als Sub Steuergerät erreichen im klimabedienteil.

monstermolt would like to know if your rear climatic control is listed as a sub system* in the main (Stg 08) climatic control unit. If it is NOT listed, then there is an electrical and NOT a coding problem. A false coding would not prevent both sytems from talking to another.

* subsystem means you call on Stg 08 and have a look at the middle part of the VCDS (e.g.) screen. You should be able to chose the subsystem (= rear climate control) via dropdown menu.

Have you tried replacing the front touch climate control with your original knobbed one? If not, please do so, just to test if the rear panel then works once again. That way we can rule out a cabling or defective rear climate control unit.

Okay, I had a look at the new scan that you sent me.

So your rear climatic control is not showing up as a sub-system
of the control unit 08. It has to show up just like your A/C
compressor sub.

Additionally to the test request from yesterday, please also check the fuse SC-7 and measure pin 2 of the 6 pole plug that goes into the rear climatic control, to see if you have 12V there. I don't think the fuse is blown, since there are more parts of the car that receive power from that fuse, but maybe there is an open connection to the rear unit. Power here is "Klemme 30", so 12V are always there. There is no need to switch on the ignition to measure it.

If you have heated rear seats (I don't think so) also check fuse SC51.

Edit2: You can also check if the LIN Bus system has continuity. To do this pull the 20 pol plug from the front climate control unit, find pin #16 (it has a violett/ blue (NOT blue/violett!) wire connected). Take off the 6 pole plug from the rear climate control and find pin 1 (also a vi/bl wire). You should measure close to zero ohms. Finally measure from pin 3 to chassis (like to the door latch e.g.). Here, too almost zero ohms is good.

If all values are good, we can rule out an electrical problem on the cable loom.

Weiß einer warum die Forumsoftware meint extra (von mir) eingesetzte Leerzeilen löschen zu müssen? Das ist ja total nervig....

I will try it this weekend and make some pictures

[jimmyvw]

I really need help with this

[jimmyvw]

As you can see. If I put old one back the rear works. If I put new one the rear is off. Coding is same.

And even with old one I do not see a sub menu

[jimmyvw]

Also as you can see at the rear it has 3 pins filled.

I measure pin 2 and I see it has 12v. The other pins like 1 and 2 are 0v

By the way the colour at the back at pin 2 is orange red

[Ciclismo]

I‘m going to go out on a limb and blame the control panel.

Yeah, that is kind of strange.

Well actually it is red/yellow 😁 Red is the main color and yellow is the coding color.

The other two pins are gnd (which is why you are seeing 0V with a DMM) and the purple/blue is the LIN bus. You can't measure that with a DMM. You would need an o-scope or signal analyser to see something there. That is why I said do a continuity test, just to see if the wire doesn't have a break in it somewhere in the loom. However, your swap test did basically the same. This means your cable loom is okay.

So, now you have to check the 20 pole plug (black with red security release) if there is a pin in position #16 coming OUT of the touch climate control panel. If you look at the panel, there are two larger flat pins. These are pins 19 & 20. They should be on the left side (looking from the rear of the panel). Next to them in the direction "right" you have two rows of smaller pins. The upper row is pin 18 to pin 10. (from left to right), so the pin #16 which you are looking for is the third (small) one from the left in the upper row.

leftmost = 20 bigger flat pin / 19 bigger flat pin / upper row 18/17/16<=third one on the top row

The rear control panel is also connected to 12V continious power and needs a "message" on the LIN Bus to get powered up. If the front panel doesn't "see" the rear panel via LIN it stores the error message you are seeing right now.
