Hi,

Did you make any progress with this, I have just got an A8 with ACC/Lane Assist and as this is only a £150 extra from Audi it can't be difficult. I will also be fiddling.

Cheers

 

Hi,

I have been fiddling and researching this some more and found (on a German site) a mention of FTE.

- MMI 3G + Hidden Menu: car / cardevicelist, on FTE
- MMI 3G + Hidden Menu: car / carmenuoperation, FTE => 5
Does anyone know what FTE is or can shed any more light on enabling the speed limit display.

Cheers,

 

Hi all,

I have the same problem. I got an A7 and forgot to order the speed limit display with the ACC and lane aisst. I tried to get it done by coding through VCDS but I get the same errors as audiman9. So I am also looking for someone WITH the Speed Limit display installed who would let me have a look at the coding. See my post in the a German forum.
Here they also have profound know who but no one seems to have tackled the problem until now.

Anybody who can help with the coding or provide a dump of a working speed limit display ?

Cheers,

Oliver

 

Hi all,
Did you found something new regarding this? I just bought an A7 with adaptive cruise control and would like to enable speed limit display if possible.
Cheers,

I guess that, since no one came back here reporting any success, there are only two options:
- either they easily succeed and left anybody else guess how to do it themselves,
- or they finally came to conclusion that 150 Euro for such activation was much more less than the effort to do it themselves...

 

Well, I thought I could be "more lucky" than anybody else, but it only seems I can just take a ticket with a number and wait in line...



But I'll try to scan some car with such feature ASAP...

In the meanwhile, if someone knows the trick, well, please tell us !!!

 

It will be nice if someone accept to activate this option for 150 euros, but official Audi resellers refused (they said that this option cannot be activated aftermarket).
I made some search and it seems that this options is enabled or disabled on controllers which have a PIN code protected access.
Somebody can confirm this?

 

VCDS scanning of a car with such option active would help a lot, but till now I was not able to find anyone...
(and scan should be made with DEBUG level at 2, so to be able to track down much more useful information).
I'm quite sure the solution is right behind the corner... but I still have to find WHICH corner...

 

Don't you think that "pin code" protected controller(s) will be a problem?

 

Yes, it could be... but... why are those controller protected with a PIN ? To control the access from outside.
THIS MEANS THE ACCESS FROM OUTSIDE is possible. And is much better than nothing.
Then it means finding WHO may know the PIN code... and it will again give good hints...
Don't you think ?

 

I think the controller is PIN protected because if not it would be to easy to add options without buying them. In an other hand, it is not acceptable that AUDI refuses to sold those options aftermarket.
I looked at some cables which look to be able to crack PIN codes but they seem to be quite expensive : more than 1000 euros.
We maybe have to wait that somebody found the way (it happened with the viceo in motion PIN code generator).

 

I perfectly agree on the whole line... at the same time I'm going to investigate with all the sources I have (legal and reverse-engineering ones, obviously...).

 

Yes, it could be... but... why are those controller protected with a PIN ?

I think it's because of the success that owners and third parties have had with enabling/fitting options cheaper than Audi charge for fitting them at the factory.

Audi want that money themselves...

Another sign of the IMHO increasingly greedy attitude from Audi, which I don't like and is likely to make my present Audi my last Audi.

 

I can understand the feeling, but I also tried "outside" and came "desperately and quickly" back... Other "families" are even worse... trust me... Unfortunately actually there aren't any Open Source car manufacturer !!!

 

Do you already experiment systems for writing PIN protected controllers? I found some interesting item in "8E Image Processing" controller but cannot write them due to the protection.

 

@stephane: sorry for the question, but when you say "PIN PROTECTED", do you really mean the ECU reports a PIN missing, or is this due to the fact you are not able to write to it ? Do you maybe mean ACCESS CODE not ENTERED, or do you strictly mean PIN missing ???

Just to be sure we are speaking the same language and not to mis-cross information...
Thank you.

 

Yes, sorry, I'm not an expert and I certainly don't used the right words to describe all of this. I mean that VCDS asked for a code when I tried to write the adaptation channel of the 8E controller.

 

Sorry, did not want to stress any more knowledge than you, really sorry...
I just wanted to be sure I correctly understood and your actual confirmation makes me more confident a solution can be found.
If VCDS asked for a code to be able to enter adaptation codes, well, this is quite common and those codes are sometimes known from the technicians at dealers' as it may happen they have to enter some "manual" correction, so I'm confident this will be found sooner or later...
I'll investigate this myself with more "efficiency"...
Which kind of "discoveries" were you able to do ? Is this already public ?

 

In fact, when you open the adaptation channels of 8E controller with VCDS, you can see interesting options regarding image processing and speed limit recognition, so I think there is something to do in this place.

 

To all those asking, no, I never made any progress with this feature. (When I ordered, it was not available in my region for ordering, so it wasn't a questiong of money.)

Again, I think they key is - if this is possible at all - in getting codings and adaptations info from a car that came with this feature from the factory.

This is the reason I'm impatient to cathc the chance to scan a brand new vehicle at my dealer...

But I recently made a small discovery: look at my other post...

 

I have a new idea, if someone feels like looking into it.

Clearly the current coding fails because the system is waiting for - and not getting - some regional information. The recognition may work just fine for all we know, it is just waiting for confirmatory or identification/location data from the navigator?

What if the MMI is not sending it? Assume for a moment that everything else is coded bueno, but MMI module is lacking sone code or adaptation that prevents it from sending data that is needed for the speed limit recognition.

So, we may have been looking in the wrong place? Well, an idea anyway for some to explore. Use my coding and then at own risk try ticking up MMI codings and see what happens...

 

By the way, I recommend against blindly inserting MMI adaptations. Someone reportedly formatted their MMI that way...

Again, best if someone could get codings and adaptations from a car with this factory feature.

What do you exactly mean with "ticking up" ???

Well, similar problems for VW car (ie Touareg) were solved with firmware update on navi unit or instrument cluster (I do not remember correctly what I read on another forum, which I googled around...).

This scaries me...
