Audi A6 C5 '98 Remote Reprogramming: Troubleshooting Nonfunctional Key Fobs & Launch 431 Error

Hello, I have a problem with programming the remote control for the audi a6 c5 98r. I have 2 "pocket knife" keys. KEY No. 1 unfortunately was flooded. After draining and replacing the battery, neither 1 key nor No. 2 work. When trying to adapt LAUNCH 431 after entering 35 (central locking), 10 (Adapt) ERROR pops up on each channel. And when trying to connect to 46 (comfort module), no communication URGENTLY PLEASE HELP !!!!!!!!!!!

Did you wash it in isopropanol?

You do not have a comfort module.
Try to synchronize manually by following this procedure:

you put the key in the lock
you press the closing button on the remote control (holding it) turn it to the right (i.e. you close)
or vice versa
repeat if I don't get it the first time

unfortunately manual programming doesn't bring you any.

???????????????????????

How many coded pilots do you have? See group 007 in measuring blocks, max is 3 and you will not code any more.
If there is so much, you need to reset the controller and remove the old remotes

in the group 007 in the 3rd field I have a value of 1100, i.e. if I understand correctly, I have 2 keys

I admit that I do not understand 1100
Which adaptation group do you have an error on?
You have the match at 021, do you have an error there too? And it should also show in the adaptation how many coded pilots are there.

at 21 I also have an error

It's either you fejsik does not work properly with this car or something with the central module.
and in the adaptation group 00?

as for face, I checked with vag and launch and it's the same

If you can, do a module reset in adaptation group 00,
If there is also an error, then probably something with the module, since vcds and launch are the same.

I can't only read any adaptation either. I read somewhere on the forum that I have to provide a pin from immo but I don't know exactly what and how to do it

If you know your immo pin, you can try to enter the 35-center. locks, then, 11-login
and then enter your pin preceded by a zero, and now enter the adaptation.
But I don't think that would do anything. In the pilot coding procedures, there is not a word about logging in before adaptation, but I read something else.

"If Adaptation Channel 21 is not available the control module does NOT support matching remotes with VCDS (or any scan tool). In those cases the remote matching procedure as per the Repair Manual and / or vehicle Owner's Manual will need to be completed"

so I don't know what to do anymore. I've already tried on 3 different Facebook pages
and for the 2nd launch and always to no avail. and when I want to reset adp, the equipment hangs and there is a problem with communication

Buddy witekd1, please, did you manage to deal with the problem?
At the moment I have an analogous problem: block 35, adaptations channel 10 and error 21 (unavailable). I can only reset the module by typing two zeros then read and save, this is the first option possible after entering block 35 adaptation. Of course I tried to do this reset but channel 10 and 21 error anyway.

Moreover, there is a risk that the previous owner of the car changed the "comfort module" and did not code it like the old one (the five-digit code). It is also not sure if he put the same number (and the same letter at the end) in the module, hence my questions:
1. How to check what number (and with what letter at the end) should the module for my specific car have the one installed for the first time? (does it only know aso?)
2. Is there any possibility to find out what code (the five-digit code) my "comfort module" should have (in the sense of the original one originally installed in the car).

My point is that assuming that the previous owner did not code after replacing the comfort module to be compatible with the old one - this may cause an error problem on channels 10 and 21? Should the remotes be coded despite not coding the module?

I will check the operation of the microswitch in the driver's lock because maybe one is damaged (or has cold February) and VAG does not see the closed and held insert in the case of manual coding with a combination of keys?

I suspect that this may be a solution to the problem and maybe your witekd1.

I will add that so far I have checked all available descriptions of the remote control coding with a combination of keys and none of them worked.

Please respond to my observations and questions - thank you.

PS. Buddy dob12 what does it actually mean:

"If Adaptation Channel 21 is not available the control module does NOT support matching remotes with VCDS (or any scan tool). In those cases the remote matching procedure as per the Repair Manual and / or vehicle Owner's Manual will need to be completed"

Is there a chance that in the original manual for the car there would be a solution to match the key if channels 10 and 21 do not work?

Address 35 every central locking, comfort module is at address 46, so for the sake of clarity.
The comfort module (46) codes depending on the number of electric windows controls, and the options of the central locking are set in adaptations.

The central locking (35) is coded appropriately for its function (e.g. selective locking, automatic locking at a speed above 5 km, factory alarm, etc.)
If the vehicle has an available address 35 (Central locking), then it does not have address 46 (comfort module) and vice versa, because the functions are assigned to the given module.

What is your current central locking coding (35)?.
Because you don't really have comfort (46)

Central encoding does not affect the adaptation channel (21), because you only encode the available module options there.

In the label after the vin number, you can check the numbers of the module for a given car.

Thank you for your response.

That's right and I understand the difference between 35 and 46 therefore I put the term comfort module in quotation marks.

I also agree that I do not have comfort at address 46, only the central locking controller at address 35. I am aware of the functionality of the central locking controller as my colleague said (selective locking, alarm, etc.) but I also do not know the system well enough to be able to 100% exclude the central locking controller in case of my problem, and I have already tried many methods of matching the key, hence the suspicion for the central controller.

The current data of the CZ controller are:
Controller: 4B0 962 258 B
Component: Zentralverrieg., TWO D28
Coding: 04750

Unfortunately, my label cannot check the components after VIN or I don't know about it if a colleague has the opportunity to check, I will send the VIN.

Returning to the problem, I am still inclined that the problem may be in the driver's lock and cold solders on the switches, but I will be able to check it only on Monday. Hence a non-working combination with matching the key by combinations with the second key.

Thanks to dob12 I am good at coding and functions.

In that case, on Monday I will check the lock, if it turns out that everything is fine, I will get the second central locking controller (comfort ) I will replace it and see how it behaves. I will inform ...

Dude Megamax, I don't really understand your transcript. I understand that A021 is channel 21 in the adaptations block, but these more decimal numbers? I did not manage to enter channel 21, but if I manage to enter, I should understand that these are further check boxes and their numbers?
If you could brighten it up a little, I would be grateful

welcome back. the problem is still not solved central does not work from the remote control I can not get a pin to log you in from what I found on the net, it is just removing the meter and reading from the driver but I do not know how to go about it.

I have not yet met with the need to enter a PIN to add remotes.
I met a few A6 where channel 21 or 1 was not available in adaptations and here only the "mechanical" key learning remains, but the central locking must be 100% functional.

Gentlemen, some epidemic on the remotes in A6.
I am 98. the same comfort module 4B0 962 258 B and the same problem, a few hours of fighting and nothing. Gra1 right, the remotes need to be programmed manually from the driver's door lock and the problem lies in the damaged lock cassette. In my case, he did not close the driver's lock (he only opened it) after replacing the microswitch in the cassette, it's OK. Unfortunately, it does not continue programming the remote control. Occasionally error 01559 DRIVER'S DOOR -No secure!

As for my case, it turned out that after checking the driver's lock there are no cold solders and all microswitches are working properly.
Unfortunately, despite the working lock, the key still does not want to be programmed.
Therefore, it seems to me that despite the fact that I cannot attach to the functional work of the "comfort module" at least the visible one, it causes that the keys do not want to code. In my case, I have not changed the module yet, but this is how it will have to end.

Hello again, somebody can read the pin from the ecu reading or only from the photos from the eeprom count

no one will help

Gentlemen, the problem is solved 2 pieces remotes programmed !!
The lock cassette was damaged, I didn't even repair it. I replaced the damaged circuit that was responsible for "securing" with a microswitch which I pressed or released during programming. To sum up witekd1 come on with this pin, while Pioro33 Check the measuring blocks group 01 items 3 and 4 again or verify your programming method. Good luck.

Thanks mery5 for the answer.
Can you somehow describe the circuit you replaced with the microswitch? I do not understand what you wrote ... apart from the microswitches in the castle, did you add an additional one?

And to be sure of the programming methods I used, you can include a description of yours.

Thank you

And so :
to assess the efficiency of the lock cassette, as I mentioned, make a preview of group 001, position 3 and 4. In position 3 we have "Feedback Driver Door" after opening with the key, it should be "unlocked" when closed, "blocked", while in position 4 (here I had a fault) we have The "SAFE-Feedback Driver Door" should be "unsecured" when opened with the key. When closed, it should be "secured". The SAFE function is checked by the F243 contact (microswitch) and the corresponding yellow-blue wire in the lock. Pioro33 for me, there was always a mass on this cable both when opening and closing. In order not to disassemble the cassette, I cut the yellow-blue wire and put a monostable switch in the place of the cut. During programming, i.e. after closing the car, I opened the SAFE circuit while opening it, thus simulating the correct operation of the F243 contact.
Attention : microswitches and the associated solder in the cassette may be operational, damaged (broken) or not "driven", while levers or arms cooperating with them may be functional !!
Below is an appendix with a proper, I believe, programming procedure from the lock.

central works. cartridge replacement helped, mechanical coding. thanks to everything, especially the mery5
