Hi everyone, Having a bit of a problem with convenience consumer display for heated seats on a 2014 Golf. After retrofitting a new bcm from Passat, 'Convenience consumers' display in car menu shows 'rear seat heating' when either driver or passenger seat heating is on. Seat heating works normally. I guess that I must've missed something in adaptations of bcm, but I had no luck finding it so far. So to be short, is there a way to disable rear seat heating on bcm? Any tips are welcome

^^^I'm just guessing - but what was the value of Byte 3 on the old BCM?

Where can i find it? The BCM setting Byte 3?

floppy:post-up a copy of the long code value from the old BCM - it will be on a scan report, or back-up file for the old BCM

I initially copied the long code from my original bcm and the coding was accepted. But it seems that long coding changed by itself and I'm seeing some differences on latest autoscan. I find that weird as everything related to bcm works normally in car, same as with original bcm. Anyway, my byte 03 on original bcm was '66' and on a new one it's '46'.

OK - don't quite understand what your saying- sorry. If your new BCM "does not support long coding" then you can't impose the original coding on the new BCM - because there are no long coding software switches. In these newer type BCMs, ALL the old long coding software switches are in adaptation channels
Bits 2-3 on Byte 3 determine the heated seat setting like this on VCDS: If Byte 3 on your old BCM was hex66, then the binary value was 0110 0110. For binary values, Bit 0 is the extreme right-side digit - so Bit 2-3 is the 3rd & 4th digit from the right side (see the blue digits). This means that in the language on my screenshot, Bit 2-3 had a value of 04 (i.e. really, hex04).
To confirm that the old (long code) BCM setting is replicated on your new BCM - go to adaptations - then search for the word Seat heater level and you should be taken to a bunch of adaptation channels with the "Parent" name Seat heater level current consumption allocation. Then select Sitzheitzung_CAN- is the setting for this channel on your new BCM Heizmatten am BCM ?

Sorry, my bad for putting it a bit confusing - although VCDS says coding the new BCM is not supported, I copied the original long coding from the original BCM and it was accepted. Not sure if it did anything though. I suppose then, as you said, altering adaptations later caused long coding to change from the one I copied originally.
'Sitzheizung_CAN' is indeed set to 'Heizmatten am BCM'

'Sitzheizung_CAN' is indeed set to 'Heizmatten am BCM' hmm........ yes, I suspect that the copied long code string wasn't actually accepted by the new BCM (again, because there ain't any long-code facility in the new BCM - and most importantly, because your new BCM has the 'Sitzheizung_CAN' adaptation channel.) As for solving your problem - it's getting more complex!!! Perhaps check the following channels in the Gateway module (hex19): Range gain Range gain rear seat heater Range gain rear seat heater (yes, there are 2 channels with the same name - left and right-side, I suspect) These channels should be set to not activated
Efficiency program display
Comfort use rear seat heater
On my module this channel is set as activated (even though I don't have heated rear seats), perhaps try not activated (guessing)

Thank you so much Don, setting these channels to 'not activated' fixed my problem! I would've never suspected that gateway adaptations were the cause of this - as I never even noticed it was displaying rear seat heating incorrectly until checking all functions once I replaced the bcm. I've been banging my head because of this for a month now... Thank you once again!

New Firmeware is on, but nothing changes, the Control unites are doing nothing, when I enter the Rage deactivate Rage for Seatheater nothing change.
Please see the Attachment, which is my Log i don´t know, why i don´t see the Display from the Seatheater and also why i have 4 Seatheaters but 2 Physical.

dv52 (Australia) I will have my Display from the Climatronic and also i will have in the Covenience Consumer Display 2 Seat Heater not 4. It doesn´t Show Seat Heater on Display when i activate them also the Current its 4 Seat Heater. But I only have 2 Physical in Front, not Rear in the Convenience Consumer Display. Also I missing by my MIB 2 Media Compoestion 2. Generation its from BJ 05 / 2015 my Car so i have the Media Compesition thinking MIB2. Before the Battery and the Loader unit was changed the Radio was able to Display my SeatHeater Control steps 1 2 3 and off Display also when I turn the Climatronic more Power and Less. So that Display is thince the Change still not to see. Please dv52 (Australia) check my log. history.txt (51.4 KB) dv52 (Australia) here ist my Log please check it, i have tryed it but think perhaps i have an Error or Misstake on the Control Unit, so please advise what i can try.

I dont know whats wrong i have no errors but under hex08 under Adaption is the clima Mode deactivated. I have See when i activate it nothing change also hex 19 range seat heater rear deactivated nothing change on the units. Now i have still parking the car before i get to work i have deactivated in hex08 under long coding clima Display and seat heat menu but nothing change but i let it Set in the hope when the unit after 30 Minute Power off they Release on NEXT Start the setting but i can Code what i want nothing change. dv52 (Australia) Do you know is it troubleshooting when i get to the dealer and let them check? I was by a dealer they told me my car is stolen because other id in the log the dealer Has coding 3 units New the boardnet unit 5f and climatronic but i cant change anything i cant See any change they have uses Odin and vcds. I have a advanced warranty by VW so i have let them change the battery after that i dont have an Display on Radio they dont Display my seat heater the Menu from the climatronic is there but when i activate the seat heater before the change the Radio Has Display me the changes 1 2 3 Was Display with a graphic and the climatronic Power up by turning up the climatronic was Displayed automatic Now i dont See the seat heater Display and the climatronic Display only when i press menu then i have nothing errors but i dont See the seat heater changes only the LEDs on the climatronic i See but nothing in the Radio so the Problem is i have one Front seat heating but Not rear under convenience consumer Display i See the Front and rear seat heater so i change the hex 19 range seat heater but nothing change. The dealer Has reset my unit and Coded like Odin it will.

@all or dv52 (Australia) i have under settings the Workshop number 12345 what is it?

Post by dv52 (Australia) on Feb 5, 2020 11:07:16 GMT
^^^ floppy: the "workshop number -' or more accurately the "WorkShop Code" (WSC) is a five digit number that historically identified the dealer. Every registered Audi/VW dealer still has their own individual WSC.
My understanding is that long ago (probably before dealers were connected though a common network), the WSC was used to identify which dealer worked on modules. So for example, if dealer A changed a module, the WCS was recorded on the module so that dealer B could identify who previously worked on the module.
I also understand that at some time in the very early days, the WSC was used for warranty auditing and/or crash investigations and it's possible that it still is used for this purpose today (I'm not sure)
AFAIK, and at least for OBD11 software, the control module doesn't much care what WSC is used: basically any 5 x digit number can be used as long as it's accepted. The WSC doesn't affect the way that the module is coded.
As to what WSC 12345 means - I suspect (I don't know for sure) that if OBD11 finds a previous WSC recorded in a particular module, then it will use that recorded WSC for the changes made by the user. However, if OBD11 finds a zero WSC (i.e. 00000), then it imposes 12345 as the WSC (OBD11 probably does the same when the software finds a zero Importer Number- but that's another story). This is an accepted protocol that is used by many non-ODIS diagnostic cables - VCDS does exactly the same

Okay it was just a question i dont know what i can Do because odb 11 Apps are working fine only the long coding and Adaption are without any solution. dv52 (Australia) can you Tell me the settings with vcds where can i find range and seat heater there? I have a friend and will ask him to that so which way is it in vcds?
