2015 Audi Q7 Backup Camera retrofit Installation/Coding/Calibration
As I am sure many of you know, there are lots of posts out that the talk about retrofitting a backup camera to an Audi Q7 (4L). What I found, however, was that you had to piece together all sorts of different information and posts to get a complete picture, and even then you had to guess on a few things. I thought I would post what I did from top to bottom, hopefully helping others that want to do this in the future.
For starters, I bought the system new from Kufatec US, as I wanted all new OEM equipment and avoid compatibility issues. You can find parts on eBay, etc. and buy the harness from Kufatec, however you don't save too much and I found the Kufatec directions very helpful to have.

You can also find the cheaper China made versions for $300-$500, but I really didn't want to do that in my new Q7. I wanted Audi OEM and the ability to fully integrate it into the vehicle properly.
You will also need tools to remove trim panels and the MMI head unit, I got mine here:

Unfortunately when I installed mine it was 20 degree Fahrenheit outside and I did most of it in my driveway (to have more room) so I didn't take any pictures of the installation. I had all the service manual procedures to remove all the trim, etc., that was very helpful. If you want PDF's of that just reach out to me and I will send it to you. The physical installation was the easy part, the Kufatec harness integrated perfectly into the cars existing electrical connections, even using the factory fuse location. Took about a total of 3-4 hours to pull everything apart and get it back together. Audi does a really nice job on their interior panels, lots of bolts, high quality snaps, nothing broken at all taking it all apart and putting it together. In addition to what Kufatec sends you, you will need a 5 amp fuse and the two metric nuts to mount the controller in the factory location. A quick trip to Home Depot solved both.
I did make one grand mistake, and costed me 2 additional hours of my life that I wasn't counting on. I took apart the CAN BUS breaking plug just fine, and inserted the CAN BUS H/L pins from the Kufatec harness. What I forgot to do, was to put the CAN BUS connector back together before I turned the key on and tested the system. Talk about lighting up DTC's like a Christmas tree, don't make the same mistake I did, it took about 30 minutes to go into all the modules and clear all the codes plus the travel time to use the scan tool. Very dumb.
Now that everything is back together and the codes are all cleared, time to do the coding and turn it all on!
If you buy the system from Kufatec, they offer a Coding Module that claims to automatically code the backup camera to your vehicle. I made the mistake of buying that, only to find out it only does partial coding and is not appropriate for my vehicle. Suffice it to say since you have to do more coding anyway, I wouldn't bother with this and just go find someone with a VCDS to help you get it coded.
The steps I used to code the backup camera properly are as follows:
(1) CAN Gateway, Address 19 - (this connects the RVC controller to the CAN BUS) enable 6c for the Rear View Camera
(2) MMI Head Unit, Address 5f - (this is how the RVC shows up on the MMI screen) - In VCDS, go into Coding, Long Coding Helper, select "Byte 7" and turn "Bit 1" on. Now the camera will show up on your screen. The final code for my vehicle was: 010000060004E1EF010023056F6300030200
(3) Advanced Parking System, Address 10 - (this connects the parking sensors to the RVC) - In the Kufatec instructions, it states to set "Byte 00" to "Bit 5". This did not work for me. When I went into the Long Coding Helper in VCDS, I had three settings I needed to adjust as follows:
First, I have the factory tow package and that needed to be enabled.
Second, the VCDS showed the "Optical Parking System" as inactive, with four different options. Those were BAP 3.3 Inactive/Active, or BAP 4.0 Inactive/Active. I chose BAP 3.3 Active, and now the visual of the car with my live parking sensors shows up on the screen. I like having the Optical Parking System on the MMI screen, however I do not have the front parking sensors installed, so those show as red and inactive. The rear ones work fine on the screen in addition to the audible beep. Since my car was built without the front APS sensors and the RVC, I am told this is a software issue and no way around it. I did try using the BAP 4.0 Active setting, however that coding was rejected and would not work, so back to BAP 3.3 Active.
Last, there is an option to tell the APS that a RVC is present. Turn that on.
Once that was done, the final coding was: 25011E (Security Access Code 71679 was required)
(4) The Kufatec instructions talk about Address 17, however I did nothing with that. Not sure what that is or if I even have it in my base Q7 Premium. If it ain't broke don't fix it!
Now, to the final step! Coding 6c the Rear View Camera and Calibrating!
(5) Rear View Camera, Address 6c - To do this you will need download the calibration PDF (go to FedEx and print the calibration board ($12 for me). A great post here to do this: http://www.audizine.com/forum/showth...ra-Calibration. It is necessary to do the calibration so that the steering lines work correctly and so that your view behind you is not distorted.
I got the coding and calibration instructions here: http://wiki.ross-tech.com/wiki/index...Back-Up_Camera. One issue, however, is that this omits the critical information about the "Camera Height". You must input the correct camera height for the system to calibrate properly, otherwise you will get a "Not Calibrated - Out of Range" error message. My camera measured out at 1000MM/39.4" high (ground to camera center), so I coded per the following:
Coding 6c control unit
The code is composed as follows:
1 X X X X X X : Always (Audi)
* 0 X X X X X : Always
*** 0 X X X X : Without trailer hitch, without optical parking system
*** 1 X X X X : With trailer hitch, without optical parking system
*** 2 X X X X : Without trailer hitch, with optical parking system
*** 3 X X X X : With trailer hitch, with optical parking system
**** 0 X X X : Always
****** 0 X X : Camera height 1 (970mm) 38.19”
****** 1 X X : Camera height 2 (985mm) 38.78”
****** 2 X X : Camera height 3 (1,000mm) 39.37”
****** 3 X X : Camera height 4 (1,015mm) 39.96”
****** 4 X X : Camera height 5 (1,030mm) 40.55”
****** 5 X X : Camera height 6 (1,045mm) 41.14”
****** 6 X X : Camera height 7 (1,060mm) 41.73”
****** 7 X X : Camera height 8 (1,075mm) 42.32”
******* 0 X : Always
********* 1 : Q7
With this, my final coding was 1030201 (Audi, OPS+Tow, Camera Height 2, Q7). I have the rear acoustic parking sensors, and enabled the Optical Parking System on the MMI screen, so that is why I used 1030201. If you don't have the tow package or enable the OPS screen on MMI, then code appropriately.
Then, on to calibration. Using the Ross-Tech Wiki instructions, I used the following values:
Security Access - 22351
Channel 005 - 500 (calibration board laying flat on the ground)
Channel 004 - 15474 **(20000-3002 (Q7 Wheel Base)-1524 (Calibration board 1524mm/60" behind center of rear wheels) = 15474)**
Channel 001 - Set to new value of 1 and the calibration procedure is performed
Then per the instructions, go into Measured Value Block 130 and check calibration status. You should see 1.0 and 0x0000 (Calibration Successful). If it doesn't work, you entered a value wrong or aligned the board incorrectly behind your vehicle. Just check everything, correct any issues and re-run the calibration.
I hope this is helpful, it sure made things easier for me once I understood all of this together!
