Trying to do retrofit on this particular car. Codings/ADP done so far:
Car in question:

Engine 01:
Byte5 Bit 4 - Trailer Installed

ACC 13:
Control_module_for_towing_sensor --> Installed

BCM 09:
ENG122979-ENG141968-Networking-Anhaengeranschlussgeraet,adapted from,not installed ,to,installed

Trailer 69:
0200000202001200 to 0100000202001200 Byte 0 From NAR(02) to EU(01)

This got all the fault messages gone, but for now swiveling still doesn't work.
I'm guessing this module also needs parameters?

What type towbar is it?
Where is it sourced from (i guess no activation card)?

[01], you probably mean Byte 5 Bit 4
[10] Byte 3 Bit 0
[13] Byte 1 Bit 7
[19] Byte 15 Bit 6, Byte 19 Bit 4
[6C] Byte 2 Bit 0
[6D] Byte 1 Bit 7

Yes think so too, what does [1A] show?

It is original Skoda Towbar with swiveling(Not fully electric) I guess but without act card.
Dealer itself made the offer, but in ETKA VIN filter doesn't rule it out, but has a warning not for "iV RS".
It Does have SVM code TOWAB next to it, but it isn't valid in ODIS.

I can check and record 1A, but I didn't see anything that refers to dataset.

It needs to be unlocked using ODIS online and running SVM procedure. You can't just upload dataset to 5H2 module, it wont work.

Yeah but not possible with Odis, because it being iV RS so officially not supported.

Which kind of unlocking are we talking about here also? SFD?

You can try make SWK from other Octavia VIN.
It will parameterize and unlock the button for swivel.

Trailer now functioning.

I had to do different coding on 10 and 19 though. It is swiveling, not fixed/mechanically removable.
Also needed dataset. As this is being "gen2" dataset seems like it doesn't show up on 1A.

I've uploaded fresh ascan+adp to scan folder:

Good to know it worked.
What did you recode in 19? And what is 1A that you are talking about?

Under "exp coding" there is option to select swiveling not fixed. Byte is same as NeTech suggested.

1A - Advanced ID

So you did not upload dataset to 69?

Only coding and the swivel now works
