VCDS Tweaks

[Wynnston]

We used Ross tech on Laptop to do ours and its pretty easy. See my post above for the high beam assist. You just have to change the numbers outside what is there as drop down options as it didn't have the LED option showing on ours. worse case it doesn't work and you change it back. Only relevant if you have a 206 TSI though and are trying to do high beam assist as the Xenon shutter option def doesn't work, you just lose high beam.

Is the throttle pedal sensitivity mod the one where you tell it you have an "Audi" engine? I've heard mixed reports about it causing issues with ABS units...

Yes, and no issues to report...Just a more sensitive pedal!

Odd. Mine is just on already. I don't recall having to use VCDS. It sits in the menu below Lane Keep Assist and I either tick it or not. Basically makes the car fairly autonomous on the open highway, it just gets ****ty if your hands aren't anywhere near the wheel for 10 seconds or so.

Sorry Wynnston, I should clarify.
The standard lane assist kind of pinballs the car in between the lines. Apparently there is an option on the Tiguan's to enable Adaptive Lane Assist which keeps the car more centrally to the lines.

[Wynnston]

Yes. It's called Adaptive Lane Guidance and it's just a menu option on mine. I'll try and remember to take a photo for you

Thanks Don. Will keep looking.
Interesting as I my brother in law and me had a tinker last night, He has the new 162TSI Tiguen so has been playing with that too and the two cars are a bit different. While mine has the 51 code for an Australian model my MIB unit is quite a bit different in spec overall as we were wondering why on the the radio settings mine doesn't show advanced settings as an options but everything else looks the same etc.
Driving over there last night I did however get one traffic message so it is in fact working so no TP reference as an option to disable anywhere but it did have the message and associated map. This morning showing nothing so I guess nothing loaded on SUNA this morning and I do wonder about the availability and useage in NZ too.

Another hint specifically for the 206 Passat only with LEDs currently and I would say 7.5 version Golf R and GTI is that when enabling light assist (which is pretty good I might add!) for cars with LED headlamps required a guess on the long coding that we couldn't see on our VDCS.
We had to change the longcoding in byte 2, last lines below, that was set at 1B to 1D. 1C which we could see referred xenons and light assist as below and looked like it was working until I tried it in the dark and I lost high beam.
So we tried 1D which wasn't an option we could see to select and it is working no problems.

To Activate High Beam Assist (Light Assist)
Open controller 09 - Central Electronics
Security Access 16 – enter 31347 and press Do It
Adaptation 10 – use channel drop down box, go to:
IDE08786-ENG116637-Assistance light functions-Menuesteuerung Fernlichtassistent
Change Stored value from Not Present to present. Press Do It.

Open Controller A5 – Frnt Assist / Driver Assist
Security Access, use code suggested by VCDS
Go to Coding
Open Long Coding Helper
Go to Byte 2
Use drop down box to change to Light Assist. Default is Inactive. Exit. Do It

Go back to the Central Electronics module, enter the security code
Go to Coding, Long Coding Helper
Go to Byte 2
Change from Bi-Xenon w/o Light Assist to Bi-Xenon with Light Assist, Exit, Do It

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?

That means vcds doesn't have a descriptor file for that BCM part number. Have you updated to the latest beta 17.6?

Ah, yep. That will be it. Didn't realise you guys were using the BETA. I am just using the standard release version.

Looks like I lucked out, I just tried the BETA, still no options.

If it's too new you should email rosstech with the info so that they can start compiling the data required to build a label file.

It's really odd, I have the first delivered 206 in Western Australia, if it works for another 206 I would have thought it would for mine. This is the actual error I get.

[kamold]

Haven't seen that.

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)?

[kamold]

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)?

Don

[kamold]

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
