Hello VCDS community,

first I have to thank Uwe for this great tool (VCDS), which gives me so many opportunities with the car.
I love it. Thank you very much for that. :thumbs:

A short introduction to my person. My name is Thorsten and I am an electronic engineer and computer guy from Germany.
Since English is not my native language, I ask to excuse the one or other spelling mistake.
Usually I know exactly what I am doing when I change something in the vehicle coding,
but now I have a serious problem with a coding in a control unit which cannot be undone.

I am addressing all VCDS professionals, hoping that someone might be able to help me with this problem.

Here's the problem:
Coding in byte 3 of the control unit speedometer (Switch panel insert J285) cannot be reversed.
Error 22: Value range or parameter invalid

It is a car that probably isn’t available in the US but the problem could be the same across all the VW vehicles.
It is a MAN TGE (UY-VN54), which is identical to the actual VW Crafter2 (SY) VAN.

In the control unit speedometer (J285), I have already been able to change the coding with a HEX-V2 without any problems. Because I am thinking about mounting bigger wheels and tires, I have tried to adapt the speedometer display to the larger rolling circumference. Therefore I have tried to change the wheel circumference in the control unit of the BYTE3 from the standard version 1 with the HEX-coding 88 to the version 8 with the HEX-coding 8F. So it was changed from the smallest to the largest variant. The control unit accepted this and in the following test drive I also found out that the speedo now goes ahead 16% instead of the original 4%. So at first it worked as I had expected it to. But now I wanted to undo the coding again and send the old coding to the ECU. But the ECU denied me the coding with an error 22: Value range or parameter invalid. Multiple attempts were unsuccessful. It is possible to do other codings at the control unit, only the wheel circumference can no more be coded smaller and the coding is refused.
The control unit therefore in principle still accepts another HEX code, only if a different code is entered in byte 3, then the acceptance is refused.

Actually coded:
07A4118FECAC0008008A6A0F5401000000000000
Should be the old code:
07A41188ECAC0008008A6A0F5401000000000000

A theory of mine would be that the control unit allows the change to a larger wheel circumference but not to a smaller circumference and once the largest circumference was programmed there is no turning back. Can this be? Possibly it is a bug in the control unit’s firmware or it is programmed on purpose by VW or whatever.
And if so, what possibilities do I have now?

Do we have a possibility to get the wheel circumference coded back to the original value?
Thank you very much for your feedback.

Best regards
Thorsten

I seem to recollect somewhere that changing the wheel variant was a one time deal - it was recommended to adjust the speedometer via the % correction factor. This from a discussion where people were fitting large wheels to Q7s and the like. However there are limits as to the % you can adjust by - but the theme was if at all possible leave it alone in wheel variant. I’ll try and find the forum and post (not here on RT) and update

As an extra thought, is there a wheel size also in the ABS module? I would expect they will need to match

Thanks a lot for your reply. Oh, dear. That's exactly what I thought, but didn't want it to be.
Would be great if you can find the discussion.

But I still hope that this can be fixed.
Otherwise it would be a complete new control unit which costs over 1000€$

I haven’t looked or done anything in the ABS Module. This was too hot for me to change anything in this controller.
But I can have a look, if I can find anything about the wheel size in there.

It's quite unusual for a coding change to be irreversible, but of course it's possible to implement such a "feature" in the control module's firmware. Historically, stuff like that has been limited to a few Adaptation channels, for example a speed-limiter channel.

Unfortunately, I do not have any further info regarding this instrument cluster.

Sorry I cannot find the posting I was referring to.
As an interim, can you use the % calibration feature to ‘undo’ the issue?

Too bad, I would have been very interested in that posting. But it's good to know that the problem didn't only occur to me.
I would have tried the % correction before, if it was available. But I could not find a setting for it anywhere.
I can only adjust the average consumption and range in % but I can't find anything for the speed display.
Where should I find this and what is it called exactly?

General question how to proceed now:
So if I can't solve the problem by myself, is there any chance that anyone can reset the controller to factory defaults?
(Except the firmware programmer from VW who will certainly not help me with this)
I mean, technically it should be possible to reset the controller to the factory settings.

Or is it unnecessary to search for it and I have to sadly replace the complete Combi-instrument (speedo display unit)?

I have experienced several circumference coding could be changed once and then not anymore.
Especially older cars, new instrument installed and after one coding, you better have made the circumference coding digit correct!

Have you tested any of the Secure Access numbers (maybe use English VCDS) ?

I have doubt this can help, but just for testing, can you change [Adaptation-10], search: IDE00845
For example change Maximum wheel circumference to a bigger number.

I have just installed the newest english Version 20.4.11 of VCDS.
I have tried to test the Secure Access numbers but I don’t have the 5-digit code for it.
Then I tried the 7-digit PIN/SKC. I think this is probably the code that I got with my keys on a key-tag? (right or wrong?) But this code also didn’t work.

In the [Adaptation-10] there is no option to change the IDE00845
I can only display it via the Adv.Meas. Values:
IDE00845-MAS03213,Wheel circ.-Average wheel circumference for trip distance,2490, mm
IDE00845-MAS03214,Wheel circ.-Maximum wheel circumference for speed,2580, mm

No 7-digit is not used anymore.
Is there not an yellow Pop-up showed with 3 different Security Access showed, after a little while ?

I guess the Variant 8, changed it to 2490 / 2580 mm
All Crafter/MAN logs I have, show 2190 / 2278 mm

Have you tested to change to for example Variant 07 first ?

No in this controller unit, there shows up no Pop-Up with the Security Access code.

Yes I know the Variant 8 changed it to this huge circumference.

I had it changed only once from Variant 1 to Variant 8.
I just wanted to quickly test it and see the biggest difference.
If I would have changed it first to Variant 4 or 5 then it would be no deal,
because this would correspond to the tyres I would like to mount.
But the Variant 8 is much too huge for the vehicle.
And now I have had tested every possible combination, but nothing is accepted anymore.

Won’t be accepted:
07A41188ECAC0008008A6A0F5401000000000000 (Variant 1)
07A41189ECAC0008008A6A0F5401000000000000 (Variant 2)
07A4118AECAC0008008A6A0F5401000000000000 (Variant 3)
07A4118BECAC0008008A6A0F5401000000000000 (Variant 4)
07A4118CECAC0008008A6A0F5401000000000000 (Variant 5)
07A4118DECAC0008008A6A0F5401000000000000 (Variant 6)
07A4118EECAC0008008A6A0F5401000000000000 (Variant 7)

The Following are the Variants with manual shifter
They are also not accepted:
07A41180ECAC0008008A6A0F5401000000000000 (Variant 1)
07A41181ECAC0008008A6A0F5401000000000000 (Variant 2)
07A41182ECAC0008008A6A0F5401000000000000 (Variant 3)
07A41183ECAC0008008A6A0F5401000000000000 (Variant 4)
07A41184ECAC0008008A6A0F5401000000000000 (Variant 5)
07A41185ECAC0008008A6A0F5401000000000000 (Variant 6)
07A41186ECAC0008008A6A0F5401000000000000 (Variant 7)

But it accepts the
07A41187ECAC0008008A6A0F5401000000000000

This is the Variant 8 with manual transmission.
So in principle, the Byte can be changed, but it did no longer accept a code that changes the variant 8 to a smaller variant.

Would a factory/dealer software update/restore and reconfigure via VIN work I wonder? Cheaper than a new cluster

Thor-stern: Hi. I'm not sure how MQB -ish the MAN GTE is, but I'm emboldened by the "3Q0" response in your auto-scan to suggest the following:

Apropo of NEtech's suggestion regarding SA for the hex17 module - there are a bunch of these for MQB platform vehicles HERE. For post MY16 models, the generally accepted SA for J285 is 47115 - but if this doesn't work, try 25327 (I'm less sure about this SA).

Again, these are MQB platform SA s

This is also my question. Is this possible? This would be great.
Because I already talked to the MAN dealer.
But they seem to have no idea.

The technicians at my local dealer looked at me with huge eyes (like I'm from another planet and speaking martian) as I told them what my problem is.
They have no technical understanding when it goes deeper in electronic and coding.
One played for over 2 hours, with their own software, on the CAN-BUS. It seemed that he doesn’t know what he’s doing.
More than checking the fault codes is normally not their job. So the result was nothing.
Then they talked with the MAN support and tried something out. But again with no positive result.
So the MAN support was at his end and the MAN support approached the VW support.
Over one week later I got the short reply that such changes are not planned and are not carried out by VW.

They only told me to buy a complete new combi-instrument for round about 1000€$
First class customer support ;-)

So I am sure that it is technically possible, but such changes are simply not desired by VW.
But I don’t know who is capable of doing a factory reset to this controller.


@Don: Thank you very much for the list with security codes. :thumbs: The 47115 was correct and accepted.
They are surely quiet useful for the future.
But sadly, even with the SA, the change of the wheel circumference variant coding is still denied. :cry:

Thor-sten: Changing Byte3, Bit 0-2 on the hex17 module to "adjust" speedometer is a mature tweak on MQB platform cars - so lots of folks have used it multiple times to experiment with the various options. But then I've not known of its application to an MY20 MAN GTE.

1000€$ to buy a new module seems a bit steep - even by VW's exorbitant standards. If the Crafter is like other MQB platform vehicles, retrofitting a new J285 will trigger Component Protection DTCs which will necessitate another visit to your friendly dealer (and it will mean a further drain on your funds)! Of course, you could always find someone to hack the CP errors, but this can be problematic depending on how it's done.

As a very long-shot based on nothing more than a hunch, I wonder if pulling the battery lead for a brief period of time is worth trying? @jyoung8607 has suggested this in the past (see here) as a possible fix for strange VCDS problems on MQB vehicles and it has worked.


It's an easy try, so give it a shot - and it costs nothing (the DTCs generated after the battery lead is replaced should clear after a brief drive)

You can test label file, copy this file to c:\Ross-Tech\VCDS\Labels\User

I would like to thank again everyone who’s trying to help me with this problem.
I realy realy appreciate your help.

I have disconnected the battery for an hour
Reconnected it and tried the coding again.
But as always I get the Error22: Conditions not correct or request sequence error.

I also have tested the label file. But I’ve seen no difference. What should it change?

Hallo Thorsten, ich bin auf deinen Beitrag gestoßen, da ich aktuell vor dem selben Problem stehe, konntest du es mittlerweile lösen?

Hello Xaver.

Sorry, I have tried so many things, but I could not solve the problem so far.
I guess that this is so wanted on the side of VW, that this setting can only be made once and then is permanently locked.
I'm still driving around with a very early speedometer and have resigned myself to it in the meantime.
If you find a solution, please give me feedback.
Seriously, please remember and give me a feedback if you find a way.

Many greetings
Thorsten


Hallo Xaver,

sorry ich habe so vieles ausprobiert, aber ich konnte das Problem bislang noch nicht lösen. Ich vermute, dass dies seitens VW so gewünscht ist, dass diese Einstellung nur einmalig vorgenommen werden kann und dann dauerhaft gesperrt wird.
Ich fahre halt immer noch mit einem stark voreilenden Tacho durch die Gegend und habe mich mittlerweile irgendwie damit abgefunden.
Falls du eine Lösung finden solltest, gib mir bitte eine Rückmeldung.
Ernsthaft, bitte denk dran und gib mir eine Rückinfo falls du eine Möglichkeit finden solltest.

Viele Grüße
Thorsten

I am unable to see my abs coding BUT I have seen the circumferance referance somewhere where I thought was a strange place to have it. I think it was possibly in the Steer assist.

Hallo Thorsten,

Ich hatte bei meinem die Nachtankmenge, Gurtwarner und Warnung bei Zündung und offener Türe codiert. Die Rkz von hab ich zwei mal verändert, konnte sie aber nicht mehr auf den original Wert einstellen.
Meiner war die Tage bei VW und die haben versucht die Werkscodierung auf das Kombi Instrument aufzuspielen, dabei wurde aber lediglich der Gurtwarner rückgängig gemacht. Weißt nicht ob die nur den Gurtwarner codiert haben oder alles.

Mein Händler fragt jetzt bei VW an, da muss es ja eine Lösung geben, kann ich irgendwie nicht akzeptieren, dass man etwas ändert und niemand kann das rückgängig machen.

Bin auch bereit hier ein neues Kombi zu kaufen, denn durch die Änderung habe ich Probleme mit meinem ACC bzw. Notbremsfunktion. Hast du Infos ob es durch den Austausch vom KI behoben werden kann?

Gibt bis dato nur wenige Fälle, aber soweit ich das mitbekommen habe sind wir nicht die einzigen, nur eine Lösung hat noch keiner.

Ich halte dich auf dem laufenden!

Gruß
