try this please 21DD2885412900C9841A1471825600527705

If I replace it with a Bosch 9.0, will I be able to activate it?

i think the only possibilty (but not certainty) is an EBC460 6R0 from russian polo

Hi again

The latest code was also invalid.

So I used an hour or two and tried every combination from 00-99 in the third and forth last numbers in the code, as I could see, that was the ones that differs in your coding suggestions. Example with just two ##: 21DD2885412900C9841A147182560052##05


Most of the numbers got the same fault 31 and wasn´t valid. The following numbers did allow me to change the code but without putting the ESP out:

00, 01, 04, 05, 08, 10, 11, 14, 15, 18, 24, 25, 28, 41, 44, 45, 48, 49, 50, 51, 54, 55, 58, 59,60, 80, 81, 84, 85, 88, 89, 90, 91, 94, 95, 98 and 99.

And now it gets more exciting, because the following numbers did indeed put the ESP off with a bip sound when holding the button for around 3 seconds, but the tyre pressure monitor came on and wouldn´t be put out:

19, 20, 21, 25, 28, 29, 40, 61, 64, 65, 68 and 69.

Any ideas which number I should use and how to get the TPMS to work correctly?

Thank you for all your help so far!

Best regards Peter

I'm expecting the TPMS light to come on after the coding was changed. The 05 at the end does TPMS and XDS on your controller.
Does the light go away after cycling ignition and pressing TPMS button?

PS what's interesting is that you found some values that were unknown to me (last column)
I only knew 00, 08, 0C, 10, 14, 74

Do all these disable ASR/TCS with short press and ESP with long press? do you know?

Hi Peter, laborious and commendable task , but you must keep in mind the following example:

Hi again

Every time I got a valid code, I tried to start the engine and press the TMPS button, but I couldn´t be turned off. So do know how I can do that? And which code I should stick with?

About the new values, yes apparently they do all switch off ASR with one short press and also ESP with the long press. I tried driving in the snow and pull the handbrake and with only ASR off, I could hear the ABS module trying to intervene. It didn´t do anything when I had the long press and bip sound.


Ciclo I can hear there might be some combinations left that I haven´t tried!! Sounds like many hours of coding and testing it out afterwards…

Best regards Peter

yep you probably only tried valid decimal values, you can expand to HEX

hex goes 0, 1... 9, A, B, C, D, E, F
10...19, 1A, 1B...
20...29, 2A...
..
90...99, 9A, 9B...9F
A0, A1...A9, AA, AB...AF

but you only need to try bits 2 to 6, since 0, 1 and 7 are known.

so you can go from xx00000x to xx11111x, which is only 32 possibilities, if you want to experiment (and only if you want to) you could try:

01
05
09 -> OEM
0D
11
15
19
1D
21 -> tried 20
25 -> tried
29
2D
31
35
39
3D
41 -> tried 40
45
49
4D
51
55
59
5D
61 -> tried
65 -> tried
69 -> tried 68 and 69
6D
71
75
79
7D

(i enabled bit 0 since that is also enabled in your original coding)

But I don't think this has anything to do with your TPMS

Ok, I can try that.

Most of the 32 comibations you mention, I have allready done, because I tried from 00 and 01 and so on all the way up til 99. But with no letters.

So if I take them away from your list then it will look like this:

0D
1D
2D
3D
4D
5D
6D
7D

Am I missing some combinations?

As I wrote before, do you know which one is responsible for the TMPS lamp going on all the time? I don´t understand all you said about in your last post - sorry, i´m not so good with computers…

Best regards Peter

TPMS is set by the last byte in your coding (05) and not the first-to-last one that organises ESP button behaviour.
You could try to set the last byte to 04 and then to 05, see what happens.

hmm... sometimes/in some control units, functions can be modified/adapted in so-called adaptation channels.
I think it would be advisable for you to take a look at 'Adaptation' of your ABS unit (03 Address) in case you find something there. Also do a complete read/log of all channels. https://www.ross-tech.com/vcds/tour/con ... ls-map.php
Example for 09 Address (BCM): https://drive.google.com/drive/folders/ ... sp=sharing

Some channels may require a 'security access' to view/access them. There are many well-known 'SA' ...

Hi again

Now it works:-)

I started from the end with the codes I found out yesterday was valid.

The codes were 19, 20, 21, 25, 28, 29, 40, 61, 64, 65, 68, 69 and 4D.

So I tried with 19 and it did indeed put the ESP and the ASR off when I pushed the button, but just with one short push. Long push doesn´t change anything and there is also no bip sound.

The TPMS lught came on and I tried putting it off with the 04 in the end of the code, and the the light was totally gone - not even visible with ignition on.

The I gave it the code 05 again and now the TMPS works like normal.

So iichel and ciclo, thank you very much for your help - I couldn´t have done it without you:-)

Good weekend and best regards Peter

So did you find a coding you're happy with? And could you please list the codes that have two functions, so I can update my sheet for ABS codings?
