Traffic sign recognition nearly coded

**sbaffi** · 12-06-2014,12:20 AM

Hi guys,

Sorry to restart such an old thread but I coded the VZE on my new A6 4G following your indications: the first time all the necessary bits were there and coded. Of course I was getting all the same speed messages as you.

Then the DIS start screen changed into the RS6 one and even with the appropriate coding I could not revert to standard (00 for standard A6). Went back into my VCDS logs and copied the original cluster long coding. Obviously I have the VZE still active in 5F, 85 and 8E but cannot find anymore where to activate it in the cluster 17 Byte 05 bit 2 - cannot see beyond bit 1 as Ndiye in post #7 - it's like I have a different cluster now and I am not sure how to activate the additional bits because with 01110011 as in your example I just get a spoiler error.

Any idea?

Fixed it...

Fixed your fault or didi you get the traffic recognition to work?

I changed Byte 5 directly in the Long Coding from 41 to 15 and the VZE is now back in both cluster and MMI. I have "Assist" as well in the DIS now, not sure how to get a rid of it.

As for the VZE to work, not there yet.

Just wondering, the security code for the 8E module does not seem to work...Maybe it needs three pins one after the other as my old 4F 55 Headlight Control module?

BTW, anyone knows what the other bits in Byte 5 activate?

I was browsing Kufatec today and remembered this thread. They sell a few versions of the "kit" that has what they think is needed...

yeah I've seen those too, however after sending my VIN, they quoted nearly £500 to fit the bits I need!

What bits do they say you need? I thought the only pre-reqs were the image processing unit (which comes with ACC/Active Lane Assist) and MMI Plus?

If you look at Audi's self study booklet for speed limit display http://admin.audionlinetraining.com/...0indicator.pdf), it mentions the errors that can appear when traffic sign recognition isn't working. Looks like something else needs coding in the MMI to send live route data to the image processing unit in order for the traffic sign recognition to work.

Page 32 of that document shows which modules are involved in traffic sign recognition. They include the electrical system control unit, which the sends windscreen wiper status to the image processing module. Wonder if anything needs coding in this to make it work?

The link doesn't work for me I'm afraid mate. I thought I had all the hardware too as I have ACC and lane assist. I've emailed Audi and asked them as I forgot to spec it, can they add it for me and I will pay. If they do then I will know exactly how it's done!

There is a tread in the A6 forum that suggests changing the image processing module from GB to RoW makes it work. Haven't had chance to have a play yet though.

Strange - works ok here. Google "Audi Ssp 482" and you should find it. :-)

Got it! Thanks.

It says if it says outside of operational area then it's not coded for the correct country. I will have a look tomorrow to see if I can find how to change the country as that is the fault I was getting after trying to code it.
