VW Golf R OEM Versus Aftermarket Brakes - rotors and pads, braided lines

[Lucas_R]

So are you saying that in the ‘Service’ menu that there is no option to put the EPB into service mode?

Yep, 100%.

Also can’t even do the turn off Stop/Start via Carista either.

Wonder if it’s a Cupra thing ?

Any other option like unplug the caliper ?

[Lucas_R]

Must be another lock down ‘feature’ that VAG is putting on newer cars so owners can’t fiddle with anything. I have used Carista on VAG cars up to about 2019-2020 models but I don’t think ive ever used it on anything newer.

Im curious as to why you didn’t try Carista beforehand, even though you didn’t have the parts yet.

Did the conversion before I new about Carista.
Inexperience on new fangled cars (did brakes etc on my 21012 Insignia no issues)
Assumed that Carista does not differ from what I read online and saw on youtube.
Asked questions and got answers that made sense, but seems being latest model, things have changed.

Have sent Carista a Query, so see what they say.

Only alternative is to seemingly unplug the caliper (to stop it activating) and then do the necessary work. Then pending the outcome and majority of codes sorted, look at taking it to the dealer to reset EPB and then deal with any codes remaining.

That'll teach me to be impatient and expect cars to not have evolved that much in a few years !

Made today a downer

Maybe a different device such as OBDEleven or VAG-COM/VCDS may be better ?

Michael: Hello again - so the exercise with your brakes continues!!

I'm not familiar with Carista - but my strong hunch is that your MY24 vehicle almost certainly has the infamous "Schutz Fahrzeug Diagnose" (SFD). If you haven't heard the term - it's the latest form of protection protocol that VAG started to implement on their fleet of vehicles in 2020. In fact, SFD has now evolved into the next-generation version protection and its in most post-2023 built VAG vehicles - it's called SFD2.

I'm not sure which version protection your Cupra has, but it almost certainly has a form of SFD.

So, SFD was first implemented when VAG commenced "interconnecting" their cars with remote facilities - like remote software upgrades and remote purchasing of options that are installed via OTA (over-the-air) download-technology. SFD is meant to stop others hacking these newer vehicles - but it goes much further IMO! Users that want to unlock SFD modules for coding purposes on these vehicles must first obtain a special license from VAG called a "Token"- which a one-use-only/time-limited authority to access modules.

Release of these Tokens by VAG is tightly controlled and it's entirely dependent on satisfying VAG's stringent requirements! For example, for enthusiast-market users of third party diagnostic devices (like you and me) - SFD access means that the identity of users and details of the coding changes must be stored and made available to VAG if needed.

This requirement greatly changes the way that third-party diagnostic devices operate because the manufacturer must enter into a contractual arrangement with VAG directly and it must establish a database of user identity/history records that is acceptably to VAG.

As for the specific question in your quote above:

1. OBDeleven was the first non ODiS manufacturer to provide a fully integrated SFD solution
2. Despite promising an integrated SFD solution to enthusiast VCDS users for the past 5 years- Ross-Tech still does NOT support these cars for the enthusiast market. Professional VCDS users must have a separate GEKO account with VAG to generate the Token - then they can input the Token into VCDS, but this solution is not practical for the enthusiast market-sector
3. Again, I know nothing about Carista - but from my very quick read of their material, it seems that users must have a "premium account" (whatever this means??) which requires a subscription to unlock SFD and they need a different "EVO adapter". I suggest that you read THIS

AFAIK, no third-party manufacturer has been able to unlock SFD2 protocols and my understanding is that even the official VAG tool ODIS has problems successfully unlocking the very latest protection protocols!

PS: the term "EVO" in my Carista explanation (point 3.) above refers to VAG's "evo-chassis" - this is the platform on which cars with SFD are built.

Michael, you could do a lot worse than downloading the carscanner pro app onto your phone and seeing if it will work for you.

I use this for all of my coding and service requirements, and I noted that the most recent update had a new section titled 'sfd' which may or may not be helpful in your application.

[Michael_B]

Yes, the brake saga continues, but hopefully will be resolved soon .....

Cheers DV52, I found your posts on the OBDeleven forum (thought I recognised the user name from somewhere) and that enlightened me to the murky world of SFD/SFD2 ( Question on apps | OBDeleven ).

So, for me, the next step is to contact OBDEleven (Aus) and make sure that I can get to the EPB Service (and see what Carista's response is) and have a go at getting it sorted. I'll also read the link you posted.

@petemac110 - thanks, I'll look into that as well.

As much as I like tinkering, this has put me off it for the moment .....

Did the conversion before I new about Carista.

Sorry - what I meant (knowing you had already done the brake conversion a few months ago) was I am suprised that while you have been waiting for your new parts to arrive to arrive for the rear brakes, that you had not connected the Carista device to your car to make sure that it works etc and that it could communicate with your car.

So from what I understand, you have the Carista EVO adapter (its black, the older normal one is white) and you should have a Carista subscription because without the subscription you cant do anything. If you have both the Evo adapter and the subscription and still cannot connect to the car, then it must be because of how new the car is and the 'SFD' as mentioned above.

Reading this will hopefully help: Carista - what is SFD

[gerhard]

For a lot of motorised handbrake systems it's pretty easy to do the rear brakes without a scan tool. Check youtube, there are videos. Basically you take the motor off, apply 12v to the pins in the connector and the motor will wind back (thereare usually two wires, + on one side = apply brake, polarity reversed = let off brake.) Replace your brakes, refit the motor, apply the 12v to set the motor, plug the connector back in.

I don't know for sure if SFD/SFD2 would know this is the way you have done it, but it would be highly unlikely I think..
