View Full Version : [Cross post] Rear camera retrofit?

16-02-2017, 12:12 AM
Does anyone have a handy retrofit guide for any of the kufatec retrofits or similar? Putting this into a 2012 a7. I bought a controller unit off ebay germany used and new camera and loom from vag navi-systems. Looking at the wiring loom now there is a couple of extra pins etc i need to figure out where to connect them too etc., I should be able to do all work except maybe the calibration myself. Any help would be appreciated for fitment advice. A few pics of what i have to put together

Has anyone done a retrofit on a pre-facelift with front and rear parking sensors and Park assist(side sensors) I cant get mine working proplerly and trying to figure out if its coding issue or hardware issue

Just had a thought - have you done a scan to see if there are any errors? Might just highlight whats up with it

Its error free apart from the camera not calibrated fault which is expected and should not affect the function of the unit. I'll re-crimp one on the can pins which was a bit loose and also try different pins on the same bus to see if it gets it working. So close... yet so far away!

Fitted one to the wife's 12 plate A5. It too says not calibrated. It all works fine. There was some coding for it. Can dig it out if needed?

This is what I did.... (12 plate A5)

With VCDS go to Controller 09 Central Electrics, then Long Coding, Long Coding Helper, Select Byte 35 and tick bit 4. This will change the HEX value to 34.

Once Coded you need to go into the Parking Sensor Menu on the MMi, then disable Display and then re-enable the display.

The Reverse Camera will now be default when reverse is selected and the OPC display will show on the right side.

- Make sure 6C is ticked in CAN gateway Installation list.
- Make sure 5F is coded for byte 7 bit 1. - Reboot MMI.
- Make sure 6C is coded correctly. (should not have changed with SVM).
Usually 1021008.

When i was in the car today it magically was back working again.

I dont see any coding options on Controller 09 Central Electrics it only goes up to about Byte 20.

I did all the other options. Im thinking maybe there is an additional step to get it right on the a7. It should have the OPC graphic display on it are at least the option somewhere to pick if you want it displayed along side the reverse camera view.
