Hi

I did this several times(code entry)both on VCDS and on Obd11. Code in the 5f confirmation of installation change is 8B9A. Substitute code should be 4248 but on obd 11 it is buffering like for five minutes and nothing happens while in VCDS controller accepts it but the fault persists as well as the existing code.

The check sum error came after installing car play remotely via we connect store and updating software for mib 3.

The car is VW Touran 2,0 tdi DSG,EU market,MY2023

slijo : Hmm....... why do you believe that the problem with the 5F module on this car is a SVM issue?

Clearly the descriptor of the 5F error message says "Software incompatible" - which is a very different fault!

I assume that your words "the check sum error" relates to information from the  VCDS scan report for this same 5F module (I suggest that you enable Freeze-frame data on your OBD11 account so that your OBD11 scan also sees this additional diagnostic information).

So, the check sum function is a validation protocol for software. In the main, once software is correctly loaded into a module, the check-sum value doesn't change. The primary purpose of a check-sum is during the software down-load period - it ensures that the correct stream of ONES and ZEROS are received by the module when the remote facility is transmitting data.

If a check-sum error appears when software is downloaded - it means that the values of the information that was received by the module has been corrupted for some reason.

I'm not familiar with the process of "installing car play remotely via we connect store and updating software for mib 3" and this process may still require a SVM type solution. However, this process must be NON-OEM and it is likely prone to lot's of NON-OEM issues

 I suspect that if the SVM tweak needs to be applied to the download process - it first requires that the download software has NO "Software incompatible" error and NO "check sum" error!

Hello everyone, on my Audi q7 4m I have a problem with module 5F, code error B201A00 static, I looked on the forum and saw that the solution is to go to adaptations and look for confirmation of installation change and look for 4 numbers, I do that and I only have one number 0, if I try to enter a number out of 4, it says function isn't available, please help me, what should I do?

[dv52 (Australia)]

zenica: I have no experience with this model car - but an Audi Q7 4M is built on a MLB evo platform whereas the cars on this part of the forum have a MBQ platform. These are very different cars and it's not a surprise that the Golf mk7 solution doesn't work on a Q7.

Maybe post your problem on the Q7 part of the forum?

Do you know what my new code would be? Mine currently is “8327”

I suggest that you answer your own question by using the handy-dandy SVM tool created by Thirsty - HERE

Hi
The key I got is e3c7
For the fault code B201A00
Is there any way to clear it?
Thanks

nickalto : Hi.

Yes, there is a very easy "way to clear it" - see my response to k300roc (immediately before your post)

Looks like don is getting bored of answering the same question over and over when it’s written clearly how to do it yourself multiple times 😂🤣😂

[dv52 (Australia)]

vwjap : Hi.

The SVM question must be the most popular on this forum - I think!!.

But no, I never get bored by these (or any other) questions on this forum- they are ALL genuine inquiries that are real for the requestor! And, since the person authoring the request has made the effort to pen the words, the very least that I can do is treat it seriously!!

Actually, your comment has crystalized a concept that I have been intending to discuss for a while with the deities on the OBD11 mother-ship  - but I haven't managed to put my thoughts in writing yet (my real life has a much higher priority than my virtual identity as dv52 (Australia) !!). I'd welcome your comment on my idea - and the views of others reading this reply

As you will be aware, lots of "more informed" forum colleagues are wary of One Click Apps (OCAs) because they leave no records of changes made.  Clearly OCAs have a reasonable appeal with OBD11 users in general and I'm guessing that the facility must result in a commercial advantage for the shareholders. 

I don't use OCAs, but my uneducated observation is that they are focused exclusively on tweaks! Why not extend the scope of OCAs to include diagnostics?

I'm not sure how extensive this new class of OCA would be (probably not a big field)- but the SVM fix would appear to be a perfect example where the OCA could read adaptation channel setting, then calculate the XOR value and apply the answer (and clear the error-code if needed). 

Given that the ONE SVM procedure works for a number of different vehicles in the VAG stable, I suspect that it could be applied to many make/models.

What do you think?

Don

[whataboutthis]

Good idea but I did suggest a similar solution to battery coding (increase last digit by one) and they said NO.

But raise a one click app request and let's see what they say.

I would also suggest they raise a helpfile for this sort of stuff, personally don't like the blog system because it's not so easy to search on.

Answer from dev


Hello,

For this feature, we need additional functionality in our application and probably it will not be developed, because of we are focused to basic user which doesn't need features like this.

[vwjap]

Don, dv52 (Australia)
I’m not sure exactly how OCA work, they may not read the SVM as a actual number that you can do math with, but I know it can be done, as More Incredible Bash does it, but that uses GEM to access the adaptions, but SVM isn’t a problem, it’s just a way to let the techs know something has been changed in the 5F module, and I presume that is for diagnostic or something, but instead techs will just put it back to factory spec than actually look into it, as it’s quicker and easier and cheaper
And as for there not being a history for OCA I’m guessing that’s a monetary thing, as if you used a OCA and it left the signatures in history then you wouldn’t need to use that OCA again (and I’m sure they have a couple of OCA’s that arnt in the general knowledge yet)
Pretty sure in earlier versions it did store them in history tho,
I did look into making your own OCA via the ult package, but read a few complaints about it not being able to do much apart from basic stuff (sorry can’t remember what they were trying to do) as I wasn’t prepared to spend money on getting ult to actually play

Also another thing to consider is that if everything was OCA like SVM or battery then maybe less people would subscribe to pro or ultimate, just a thought


Maybe I’m just getting old and grumpy, especially with people who don’t do their homework before asking questions 😂 plus I think I’ve had the SVM error for about 3 years, since Vw did the security update on the 5f 😂🤣😂

[dv52 (Australia)]

vwjap : "Maybe I'm just getting old"? Ain't nothing wrong with "getting old" - its much better than the alternative!! And as for becoming grumpy - that's your prerogative as a right of getting old!!

Thanks for the reply - I know absolutely nothing about how to program OCAs, but it can't be rocket science!!

Anyway the entire matter is academic - I've had a reply from the deities on the OBD11 mother-ship and you are correct- apparently the OCA language can't easily accommodate the required smarts for the SVM fix and this ain't viewed as a priority matter!

For what its worth I think the issue is that the OCA Tool (as seen in the ultimate package) is built to allow you to make a change from a drop down list as you would see on the screen when you are using the app and I dont think it can be used to allow users to enter manual values (but happy to be wrong)

check out support.obdeleven.com/en/articles/5627138-what-is-one-click-apps-oca-builder-and-how-to-use-it this will give you an idea how it works.

I would try to build one for this issue but due to a bug with the current obd11 i am unable to check out adaptations offline I am afraid so cant get the codes to prove this.

With regards to the OCA if you want to understand the changes its done just do a backup before and after and do compare thats what I have done in the past.

And finally yes back in the days when we were all young the OCA showed it had been used and any long coding was also shown, this caused so much confusion according to support that they removed it.

Thanks for the heads-up! Because of my low opinion of OCAs, I've never taken an interest in the OCA tool - but I now understand the limitation of the software and why it can't be used to implement the SVM fix

Yes indeed - you are perfectly correct!! BUT................ because of Adam & Eve (and that damn snake), we live in a world of sin!!!   So, there is a wide difference between the ideal and what happens in practice.

I wonder how many OCA users (particularly new-bees) start their OBD11 experience by reading through the support material? Since OCA users are interested in quick, easy ways of modifying module coding - I suspect that very few actually have the discipline, or the inclination to understand the dangers of OCAs before making code changes!

Yes, it's easy to blame OBD11 users. themselves for not creating Backup files - but I empathize with their plight. It's a time consuming task to create the Backup material and even if this is done, because of the increasing size of the coding database in modern modules - it's not easy to compare before/after records when the moist stools in the brown stuff collide with the proverbial fan blades! And, the comparison exercise is NOT helped by the insane format that OBD11 uses in the Backup file!!

Arrhh.............. "the days when we were all young" - I can't remember those days because they were too long ago!!  And, with my apology for the gratuitous philosophy - the reality is that now is the days when we were all young (think about it)!!

[whataboutthis]

Yep users shoot first and then cry after, With regards to the dangers of OCA All I can say is the web is full of tales of problems so you should have been warned before starting if you had done much research.

On one of my car forums a retrofit outfit did say they have much more problems with caristaapp than OBD11 with regards to these sorts of quick changes.

I agree the format of the file is horrible but when I have asked OBD11 Dev in the past to do stuff to it they respond there is not enough demand for it (which i get) but even with fairly basic understanding of Excel its easy to build a tool to do the comparison and there are many apps on the web that will do it. If you recal many many years ago I did a post on how to build a comparison excel tool and we always have Thirsty's tools to help.
