Traffic sign recognition - MIB3
This will work for Australian models.
Coding is by OBD11.
You will need to open the bonnet for this to apply.

To display the speed limit on the driver's display. This coding will use road sign detection mode not fusion mode. The front camera will only read speed limits not use any data with speed limits loaded within the maps.


A5-Driver Assistance
Click on Long coding
Press the button on the top right that shows a '0' and '1' to see it Bytes mode; Each Byte has 8 bits (from 0 to 7 included)
Press the right arrow down until you reach Byte 16
Inside Byte 16 activate bit 4 and do not modify the rest
Press the Validate button
Exit Module A5 and enter Module 5F
Click on Adaptation
Search for Vehicle Menu Operation
Enter menu_display_road_sign_identification and change to Active
Enter menu_display_road_sign_identification_over_thresho ld_high and change to Active
Press the Validate button
Go back to Adaptation and look for Vehicle Function List BAP
Enter traffic_sign_recognition_0x21 and change to Active
Enter traffic_sign_recognition_0x21_msg_bus and change to ' Data Bus Infotainment'
Exit Module 5F and enter Module 17
Click on Long Coding
Press the button on the top right that shows a '0' and '1' to see it Bytes mode; Each Byte has 8 bits (from 0 to 7 included)
Down, press the right arrow until you reach Byte 5
Inside Byte 5 activate bit 2 and do not modify the rest
Press the Validate button
A5-Driver Assistance
Click on Adaptation
Road sign detection fusion mode
Change to "Road sign detection" (Road sign fusion)
Security Key: 20103
Press the Validate button

Restart the Infotainment by pressing and holding the power button between 10s to 15s and release.
In the settings of the driving assistants, the option 'Dynamic Road Sign Display' should appear. Tick "Show in instrument cluster" and "Speed warning" to "Visual".
There is also an option to warn when exceeding the speed.

Note: You will now get a warning which indicates that signal recognition is limited. This warning will appear for a few seconds in the instrument cluster after you drive off. This message is only informative and does not produce any problem, error or failure. The recognition of signals will work normally but limited because it is not using the data from the maps.
School zones at 40km/h will be detected as 40km regardless of the main speed limit and will show as a speed warning when you pass them.

NOTE:
This coding was developed using the 3Q0 front camera (A5 driver assistance).
If you have a 2Q0 front camera the final drivers assistance part to change to "Road sign detection fusion mode" is not available.

Be interesting to see if this will work in our Kamiq when it arrives.

Is almost identical to what you do in a TIguan and Golf Mk7

I have found that it is best to put the security code in first before coding or it wont let you do it (sometimes)

Hey @flipper - just picked up our Tiguan R and followed the instructions for the MIB 3 unit. Everything's works until getting to road side fusion where it is saying function not available.

In OBDeleven also byte 5 has been renamed so no longer shows bits. However there was an option names Traffic sign recognition in the third row that I assumed to be the same as bit 2..

I'll keep investigating to see if there is a way to change the bit

Well all that is available for my Kamiq 21 but what I want to know does it work for a 2Q camera as a lot of stuff wont as most have a 3Q camera

Hi there Flipper Dog
I have a MY21 T Cross with a 2Q Valeo A5 ECU and am trying to activate Sign Assist without much luck to date. Coding in the 17 kombi and 5F MIB3 (without Nav) head unit appears to be the same at the T Roc Tiguan Golf etc. However in the A5 camera ECU instead of Byte 16 bit 4 it is a combination of codes in Byte 12 Bits 3 to 7. I have tried a number of combinations here and it still does not work.
I am also not sure if it is a bus setting in the 5F ECU as I have seen Extended, Infotainment and Comfort options all being used but this may because different head units may have been installed. At this stage I am leaning on the Infotainment option.

In VCDS I am able to see 3 "fusion" options in the Adaptations drop down menu which are currently set to activated, road sign detection and the numerical value of 0. Are you able to see this last setting in OBD Eleven and if so what is the value?
Thanks

Further to my previous posts my Kamiq has roadside sign recognition from factory but I cant get it to show in the Dash, even though that is ticked in the MMI You have to change fusion to plain recognition as fusion doesnt work in our maps

@Bambazonke
Is this what you are looking for in A5 Control unit Adaptation?

Are you replying to me or him. Ive got it sorted in both the Kamiq and the Tiguan. Difference is the Tig has a 3Q0 camera and the Kamiq has a 2Q0 which isnt able to be coded very easily, if at all it seems

[Bambazonke]

This is one of the 3 options in VCDS Adaptation list. The option with the 3 choices shown above is the one that most people will have change to get sign assist to work without onboard navigation
There are however 2 additional "fusion" options listed in VCDS one is called Road Sign fusion detection persistency that is either on or off and the third option has a similar label to the first one shown above BUT has a numerical values. Mine is currently set to 0 in my ECU. I am wondering if this needs to be changed on the 2Q version as I have seen the below additional instructions to code Sign Assist on a number of forums and this third option may have something to do with this.

Adaptation
Select : channel numbers indicate end of speed limit
Importance to actively invest Show Valid suffix
View Channel Valid suffix
Corresponding value adjust default: 00100111

I have no idea what this additional coding means perhaps you may know and enlighten me & others. Have either of you got VCDS or only OBD Eleven? Does the App allow you to search for "fusion" in the adaptations list for the ECU. It may have these 2 options listed elsewhere

@ Bambazonke
I have had a look in OBD11 in the A5 module for all the TSR information.
I can't find any reference to changing numeral values.
This is under Adaptions in addition to the previous post...



These ones are under long coding...



I do have VCDS but an older version that won't work on the T-Roc.

Thank you for the pics Unfortunately the 2Q0 A5 module is somewhat different. The coding to enable Sign assist (VZE data) is in byte 12 not Byte 16 bit 4 like the 3Q0 unit as fitted to the T Roc. VCDS long coding of the 2Q0 ECU is also now showing in Byte 12 this TSR can be linked to a profile setting like you have in Byte 13. Really need to see the coding of this Byte if one has navigation fitted.

While i have been trying to enable the feature, I first get an error in the MIB3 saying it does not like the BUS setting even after changing it from Extended, Comfort and Infotainment. The second error pops up when i enable Byte 5 Bit 2 in the kombi (17) ecu telling me it's unable to source the VZA data which i know i don't have and have even disabled in the MIB3 unit to be sure. Again this is all the more the reason i want to see the coding of Byte 12 in the 2Q0 A5 unit.

I will try and get some screen shots of what I am talking about the next time i have my PC connected to the car

Hi All, just picked up a Tiguan R yesterday and came up against the same problem as Grugly. Anyone had any luck getting this to work?

Going from a 2018 Tiguan R-Line to a 2023 Tiguan R has been awesome except for a couple of backward steps in functionality, ie TMC and Traffic sign recognition. Haven't noticed anything else missing yet in the coding.

Cheers,
Nayth

Hi I really want to turn this cancer off. Does the OBD11 tool need to remain plugged into the car to make this tweak work or can I steal a mates and use it then give it back?
