U12EB00 error in STG 4B in Superb 3V5

Featured Replies

I have a Superb L&K from 2023 - MIB3. Not sure if that matters.

 

I have a coding error in Stg 4B . Multifunction Module - which existed since I bought the car. I have not really taken too much notice of it, but tried to rectify it. I have a VCP lead and thought that I might find the solution.

The problem is that in my Stg 4B I should have 2 slave controllers , some others even have 4. They should be D6 and D7 and in some scans I have seen 29 and 39 too.

D6 and D7 are the main light controllers, light controller 2 left and 2 right.

Mine has a 29 for left and D7 for right. 29 cannot be addressed in the autoscan. I can add manually a D6, but that does not appear in the gateway automatically as it is not coded / registered and I do not have an option of adding a D6 into the Gateway or removing 29 from it.

 

In addition I seem to have added an error myself as when I was going through the coding text section I ticked "Highway_light" which caused some error messages in the dash. I have removed the coding of the Highway_light again and done basic settings for the LEDs.

 

One error however will not go away -

000025 (U12EB00) Data bus front light Additional installations detected (CAN_AFS_multiple_plug_LED_Leimo_identified).

Also Stg D7 appears as not coded in Stg 19 - Gateway.

 

I have seen some threads in various forums mention that in OBD11 you can change the "gateway list" for Stg 4B. In one thread on Briskoda #langers2k explained it for a Octavia.

I have 2x Stg 4B listed and VCP does not seem to have that option to change either even though 4B is also called "Gateway" in VCP.

 

Has anyone come across this or does anyone know any workaround for this?

My lights seem to function though funny enough.

STG 4B and 29 error.txt

Edited by 26DIPP

Dont add D6/7/29/39 in gateway, there are added from 4B. 

 

Open 4B, go to adaptations, go to installation list and there add the modules Light Control (put it on Yes).

In my VCP I do not have an option - I think - to add a controller in Stg 4B. I have attached screenshots of the gateway with ALL controllers and also screenshots of the adaptation channels I can see in VCP, in total 31.

In my gateway, Stg 19, I cannot set ticks to the controllers listed under Stg 4B.

 

Does anyone with a 2023 Superb with access to ... OBD11 have the gateway listed and an option to select the 4 light controllers?

Use Odis engineering.

I do not have access to ODIS-e. That would take some organizing.

What happens if you doubleclick on the block with the green plus, just next to the Not Coded. 

Can you get the adaption channels from 4B and post them here?

 

edit:

I was hoping to find:

IDE01996-SFT00041-Installation list: specified installations-Left light control,No ,1
IDE01996-SFT00057-Installation list: specified installations-Right light control,No ,1
IDE01996-SFT00075-Installation list: specified installations-Multi-function module,Yes ,1
IDE01996-SFT00214-Installation list: specified installations-Light Control Left 2,Yes ,1
IDE01996-SFT00215-Installation list: specified installations-Light Control Right 2,Yes ,1

 

But looking at the 4B adpmap on Ross-tech from a similar controller, they are now missing:

https://forums.ross-tech.com/index.php?threads/27115/

 

Might be worth asking VCP for support or finding a local user with VCDS to see if they can recode the gateway installation list?

Thanks for the replies.

 

I am sure I have tried clicking and hovering over anything on the gateway screen with no success. I will try again tomorrow.

 

I have done an Admap on VCP using the multiscan. It is stored in an old file format - adp - that I cannot open. Apparently that file format was dropped by MS in 2010.

I will ad it as attachment. All the channels I can see on VCP are pretty much like the ones on the RT link.

 

Does ODIS still have these gateway channels?

4b.adp

Edited by 26DIPP

It's just a text file :)

 

Although the channels I mentioned are no longer present so I think the 28/29/D6/D7 stuff is now controlled elsewhere.

no the 29/39/D6 and D7 are subsystems of the 4B, so you need to add them in there. 

 

With Odis Engineering you can code the subsystems of the 4B easily.

Hi,

 

I had a look at the gateway Stg 19 last night and the green plus sign definitely has no additional function.

 

I had another thought.

I looked at https://www.glaskugelservice.de/codierung/steuergeraete-abbild#N123715 where the author published a complete controller map of all the cars controllers. My 4B is SW: 3Q0907338G  HW: 3Q0907338K. In VCP I have a ZDC file named superb_fcm_3q0907338c.zdc which is the version in the linked website - HW and SW versions are "3q0907338C".

The "C" version seems to have a gateway option.

 

My question now is, would reverting back to C from G brick the controller or would it just not accept the file if it was incompatible?

 

Re. ODIS, where is a good site to load ODIS-E from and what interfaces do you use? VAS6154 or a pass through device?

superb_fcm_3q0907338c.zdc

Dont downgrade! 

 

Buy a VNCI6154a. I can help you with the installation of Odis-E.

I just want to reactivate this thread.

 

I did buy a VNCI and eventually managed to install ODIS e 17, which seemed a right pain, but it is running now.

In ODIS you have the option to install the missing controllers. I activated these and almost immediately had some errors.Screenshot2024-10-06153731.thumb.png.0884a4a924b1fcaf3451e3e432a0d847.png

 

These DTCs are mainly in STG 4B, but also in STG 13 and STG A5.

Screenshot2024-10-06185137.thumb.png.9106de6cf67375b5ab7d28786921fe41.png

 

The error is STG 13 is:

000323 (U112300) Databus error value received (FAULT_BV1_FEHLER)

 

I did not take a screenshot of STG 13, but I will attach a VCP autoscan

 

I could get rid of 2 errors in STG 4B by running the basic adaptation and acknowledge, but the other errors remained.Screenshot2024-10-06190352.thumb.png.ee15aa5e5619e7788e389fede6e2247d.png

 

Googling for the errors does not reveal much. There is one thread with similar errors on a german motor talk site, but no solution as to how to fix them. The guy installed a new STG 4B I think.

 

Any ideas or thoughts??

Thank you for the link.

It worked. ODIS E is a great little program. I had looked at the matrix light calibration but thought that it might require some form of calibration screen.

All DTCs went or were erasable now.

Also STG D6 and STG D7 are now coded into the Gateway.

Do you have any errors when reading the whole car?

None back so far in the dashboard. I can check again tonight with VCP. Before the dashboard was like a Christmas tree.

Hi,

I do not have any experience with OBDeleven, but if it is a matter of basic settings it should be able to do this.

In my car the D6 controller was missing in 4B. VCP could not code 4B. I needed ODIS for this.

Do the basic coding. VCP can do it.

What dongle are you using?
