kamold: forgive my interference and I most certainly don't profess to be an expert on the Passat, but I note that Wynnston's details indicates that his Passat is a 2017 build.

On the other MQB platform vehicle with which I am more familiar (Golf mk7), the boffins @ VW made substantial changes to the database architecture of the BCM on MY17 cars. Importantly for Wynnston's observations, the latest MY17 BCMs on the Golf do not report any code-string values. What has happened in the latest generation BCMs, is that the software switches that were in Byte/Bits are now in the device's adaptation channels.

Is this a possible explanation for this problem? Has anyone made an admap of these newer BCM on the Passat and checked if the old code string switches appear in the adaptation channel descriptors (likely in German)?

Thanks Don,
That would explain it.
Not owning an mqb platform car I don't get a chance to see them often.
My Passat doesn't even have a BCM, it still has a CECM. I'm Rockin it old school

^^^Wow - and I assume that your car doesn't have a CAN bus either? hmm............ might be time to throw some money @ your local dealer (perhaps)?

Got CAN modules up the wazoo- CECM is just an earlier version of the BCM.
Would happily accept all contributions towards an mqb car of my very own

Odd. I have no Long Coding available on my Central Electrics Module, I mean I click on it but I can't do much (nothing is labelled). It's a 206. Did it work for you, or have you just copied and pasted that from somewhere?

Yes it worked for us. Main menu is in German the sub menu drop down boxes under byte 2 are easier to read as above. It just stopped and does not go down further than Bi-xenon as options which is why we guessed and just made up a number where LEDs would be in the sequence and it worked.
My car is older than yours though as I am in NZ. Mine was new in March 2016 so is running Golf 7 which differs from the latest Tiguen 162TSI as we have one of those too.

Yep, I can confirm that there are no Coding options for my BCM, it's all done through adaptations.

I've gotten High Beam Assist to work now. I just did everything minus the CECM/BCM coding part and it works. Well... the icon comes up and it doesn't fault. I just need to find a road that I can do > 70km/h on that's dark. I live in the middle of the city so it might be a while until I do that

Good stuff. Its quite handy on certain roads. If the high beam actually still comes on when you pull the stalk back i.e flashes, it should work if the icon is coming up. Mine it looked like it was working with the icon and blue high beam light but the high beam shutters were actually disabled until we selected LEDs vs the Zenons. We did it during the day so didn't notice the lights weren't actually changing

Wynnston: Ok, then the Passat is exactly the same as the newest mk7 (not surprising-perhaps?). Have you made a adaptation channel map of the BCM on your car yet? If so, any chance that I can get a copy -please?

Hi, I have a White MY17 2016 Passat R-line with sunroof, I love it but I hate not having Traffic Information and hate stop start.
What equipment/cable/software do you have to make the changes. I want to get one so I can change my Passat.
Any help would be great.
Thanks - Mike
