VCDS codes list
Posting this here as I believe it contains codes previously undocumented on the forum. It comes from the the OBDeleven forum, with extra functions added to the list by the poster Oberon. I'm posting as is and take no responsibility for the accuracy of the data. Central electrics control unit...
Folding Mirrors On Comfort Close (again)
I don’t think there is any issue with the BCM’s I think it down to the door modules. All 7E0 937 090 * BCM’s can operate comfort folding mirrors. Not sure on the older 7H0 BCM’s tho.
I can’t find that message, could you reply to it plsI have PMed you with my BCM coding over 2 years ago(11 Feb 2018), so you have it already
Let me know if you need anything else.
As far as I remember I am missing this label file as well, but it should be possible to read the coding manually.
This is my factory BCM and almost virgin coding.
7E0937090 - BMC PQ25 Max4 H80 0736

Very close to completing this now, i have all wiring in and connected, side door locks all swapped over etc, just need to cut the hole to locate the motor, to say i am nervous is an understatement !!
Everything is live and the dash button are triggering the door/motor etc but its obviously not driving the door yet until i get that hole cut and the motor and rail mounted

Just go for it. I hope you have a welder to patch it over if it goes wrong.
Its all hidden by the side panel so no big dramas but that plastic piece has several lugs on the back that locate around the edge of the cut hole to keep it tight (and waterproof) so it needs to be quite precise and its a very random shaped hole, why cant they just make things round ?!
There is no coding for sliding doors, only few adaptation channels.

Great work. Does this mean there will be a how to coming soon?
Yes ‘how to’ will be along at some point
Job is complete and the door is fully working, I don’t have another keyfob yet so at the moment it works off the handle or from the dash buttons and everything is as expected but I do currently have an issue ....
Since changing the central locking in the sliding door (which is necessary for this retrofit) every time I turn the ignition on the central locking does an unlock cycle (even though it’s already unlocked)
Now doing this retrofit means we take the signals from the slide door central locking unit and instead of sending them directly to the BCM we send them instead to the new slide door control unit in the rear and doing a scan gives a fault in the BCM relating to the rear left sliding door signal
Looking at the coding here VCDS codes list
We can see byte 1 bit 1 = Confirmation lock for right sliding door via CAN data bus
But byte 1 bit 2 is undocumented so I guessed that this = Confirmation lock for left sliding door via CAN data bus
But alas this does not fix it as it’s already activated and unticking makes no difference
The van/dash display responds to the door being open and shut and displays accordingly but I still have this weird quirk at the moment
I think one of these undocumented bytes/bits will prob be the reason but I’m going to need to spend an hour or two with the laptop and try and figure it out which prob won’t happen for a few days so job done but not complete
more to come .......
