No fault code found.

 

Would you mind pm'ing me your SKC, I just want to be sure that you received a four digit pin, and not the generic "18995" false pin number, as if you received a 4 digit pin and added the zero, nothing should stop you from accessing with said pin, unless it is incorrect, another route to take would be to get a key reader, and read all the keys, then input said key information into the blank boxes/fields on carprog and write those key codes to the 93C86 chip, yes you would need to un-solder again as that is the safest way.

But I will wait for your pin code.

pin code ia 3145 my friend
The process with a key reader and input in Carprog I dont know how to do it
The goal will just be to replace the key info FFFFFFFF by the key ID right?

Hello @kilog ,
I just got off a 16 minute phone call with Ross-Tech technical support, using my support time ⏲️.

The Technician and myself came to the conclusion that either you read the pincode incorrectly as far as writing it down, or the carprog read the pincode improperly, or the information contained on the 93C86 chip is corrupted, or the KESSY module is toast...

Did you read the 93C86 chip more than once with carprog to confirm that it gave the same information, so as to verify the information ?

Johnny

 

Hello Johnny,
I do read 93C86 several times for the same result.
And apart from the keys ID who were all FFFFFFFF the remaining data seems to be ok like VIN, part number etc... May be I should send you the dump in l’éther for the Ross-Tech technician to confirm is yes or no the file is corrupted?
in the meantime I will read the dump again and input the key ID in the dump and see how it goes.
Best regards

 

I also am leaning towards the thought that if all the other information such as VIN being shown is correct, along with the proper VAG KESSY module part number as shown, and the Config PSW and Crypto numbers, then how can the information be corrupted, the RT guy said it still could be, sorry, but I don't see it that way, usually you get all, or nothing when good or corrupted, UNLESS someone has been in the bin file or changed hex coding prior.

So the pin number you got and received as the same by reading a few times to verify should be correct.

BUT,
I have to ask, being that I re-read this from the beginning again, you have never given us any history as to what occurred if anything leading up to this fault, is this your personal vehicle, or are you a shop working on someone else's vehicle, you do have a laundry list of scanning reading and writing tools..

And according to your other thread, you have fault code 01176 ""Permanent Error" on the Key, or keys, yet you show us a ROSS-TECH VCDS scan here with different information, it's best to keep this all to one thread 😉.

Hello Johnny
I am the one who was wrong.
The mistake comes from reading the eeprom thus the pin code generated.
I went on the bench again and read the eeprom 20 more times, far many more than the first time:
- all the 20 files are the same and they generated pincode 1089 (while the first one was 3145).
- from Carprog point of view all the fields are the same except the pincode.
- file compare between the first dump and any off the 20 new dumps give the same bunch of differences.
Now I tried to input the key ID inside the Key Info fiels in the Carprog, but that is impossible
Carptog support confirmed that "this software only supports immo data reading".
As I am taking a break for the week-end I asked one of my collegue who have equipment to generate transponder to start the car.
So far he read the eeprom again and had the same 1089 pin code
To answer to your question It is not my car.
When I will be back I will evaluate the situation and the mood of the client and try or not to program the keys from VCDS as advised.
By the way as Carprog is not appropriate, what is the best tool to program VW keys on the bench.

I am really grateful for your support
Regards

Hello @kilog ,
Ok, now that you have what we hope to be the true pin/skc code, I would not attempt to use anything but the Ross-Tech VCDS now to rematch the keys to the vehicle.

Just so we are all clear, I noticed that you called them "genuine keys" in your other thread, I want to be sure that these are the 3 original factory keys that came with the vehicle when new, or possibly added by a Bentley dealership at some later time, and NOT 3 second hand keys that the owner has picked up used.

As far as carprog working for both reading and writing of data, it does, I have done it myself, but you better know how to use it, and most importantly, use a good A6 clip, not the cheap clip that most likely came with the carprog kit you purchased 😀

I use a 150m sop8 socket eeprom holder with carprog that I solder the 8 wires to, or I use the serial Ponyprog eeprom adapter with the same 150m sop8 eeprom socket plugged into the Ponyprog serial adapter as pictured below, as I just did rewriting my 2011 ecu's.

BUT, for your use you are just reading the pin with carprog, then using Ross-Tech VCDS to pair the original keys back to the vehicle.

As far as programming keys on the bench, I do not do that, I get the pin with Carprog, and program the keys in the vehicle with Ross-Tech as per instructions, BE sure to have all three keys with you in the vehicle, but not together, placing them on the passenger front seat is fine, then do 1 key at a time in the ignition as instructed, I believe with the whole process not lasting more then 1.5 minutes or so.

Have a great weekend, clear your mind, and come back fresh to try the 01089 SKC to get the keys done !

Best of luck to you !

Hi folks, ansd Johnny particulary...

My collegue from the bench programmed 01 key that did not work.

Finally I was able use VCDS and the good pin code to open the security folder and program the keys.
The steering wheel is unlocked with all the 3 keys and the ignition is on as well.
But when I remove the last key and wait a while and try the keys none of them operates and the steering wheel is locked again.
When I enter again in Adaptation menu I discover that the number of keys are still 1 (the one programmed by my friend that is not working)

So can you please tell me how tosave my adaptation after the last key is intoduced in ignition within the given 60sec

Regards

For your information here attached are the files of the scan before erasing faults and after erasing the faults
the sanning sessions was done before remowing the last key while the steering and the ignition were opened.

 

Hello @kilog ,
I am on my phone right now typing this, so I do not have Ross-Tech in front of me, nor can I open the 2 files you attached.

So, let me ask you this, did you input the number of keys as "3" in the Ross-Tech program ?

Johnny

 

Like this,

..

 

It is what I did.

But to be precise I have 2 questions
1- At the begining after pressing brake pedal for 20sec to wakeup diagnostic databus do I release it or do i maintain it pressed
2- is the key introduced at the beginning the 01 key or the 00 key (meaning that I should remove it at the begining of adaptation and reinsert it again).

 

I held the brake pedal for whole time, don't press the pedal to hard, just enough to turn on the brake lights, do not pump as some have shown in videos, just hold.

The key number should be 01 , 02 ,03 as far as I recall.

Please see my prior as to the numbers of keys to be programmed, did you open "05-start/Auth", then select "10-adaption " then enter "21" into channel and read, then enter 03, then click "TEST" and then click "SAVE"?

Please post a screenshot of the information shown in adaption channel 21.

Johnny

 

Am I reading correctly, did you program all three keys, and had success, but before you turned off the third key and closed the Ross-Tech VCDS, you ran a full scan instead... ?

Johnny

 

Yes

Here is the Adaptation screens
Please tell me can I count as 1st key the one that release the steering after turning the key for ignition?
