VCDS/ODIS issue on MY24's

[scottyuk]

I've coded a few things but couldn't code Module 46 for beep on unlock. This was due to the module being secured by SFD. I obtained a token, applied it and the module said unlocked but when savong the code change, it still wouldn't and passed back the same security error.

Apparently MY24 cars now come with SFD2. The provider of my token said even their official ODIS tool can't do this at the moment.

No beep for me for the time being 😢

Interesting... I wonder if this is a precipice of VAG coming out with subscriptions for everything. Lock it all down so only they can sell it...

By chance did you have hood shut at the time you tried to code this change?

Yes I did. You think worth another attempt with it open? I know some stuff in vcds mentions this but would that throw a security error?

I’d give it another try for sh!ts and giggles. Open the hood before unlocked SFD and code away.

SFD no doubt started as a lock down of configuration modification as VAG, and other manufacturers, were eyeing microtransactions for vehicle functions. In the past, the vehicle was built with X, and after that, if you wanted Y, you just had to retrofit it. Now, oh you want superfluous show off feature Z for that VIN, that'll be some cost for the unlock privilege. That model doesn't work if people can just mod the vehicle config themselves. We see exactly this basis with the B9 Q5 hitch kit, where the SVM doesn't do you much good if you don't have the activation PIN that comes with the purchase. This is all about securing the new nickle and dime revenue stream.

VAG definitely working the money grab benefit of all this for themselves.

For OBDeleven, it's not much of a change, mandating the PRO annual subscription, since you needed that anyway to access any modification functions. But for VCDS ecosystem, it's pure scam. Per incident payment just to replace your battery, or reset the inspection reminder? Remains to see what Ross-Tech works out, but it's clear AoA is not attempting to be helpful to US VAG owners whatsoever here. https://forums.ross-tech.com/index.php?threads/22068/

As for is MY24 implementing "VAG SFD phase 2", or "VAG SFD2", or just "VAG SFD running change", who knows. It would seem odd for OBDeleven to have an inked contract over SFD with VAG and then that stops working for MY24. It was interesting that in the parts catalog, for the latest rev of the Q5 hitch accessory, there was a comment "but we can't do any activations until after mid August". So just more "a car company trying to masquerade as an IT company", what could go wrong.

Looks like the UN R155 "cybersecurity" regulation is the official driver for all of this. But you can be sure VAG has business types all over how they can work this for their pocketbooks.

I enquired and was told no point trying again.
