Got my original camera install finished this weekend.
Sharing my experience for those who might like to repeat. I have zero experience with cars so if I can do it, you can do it too.
Part numbers needed:
- 7E0980121 - Camera, got mine for 34 quid used
- 7E0980561A - camera housing, £9 new
Also, There is also a version of the camera housing that has a tailgate unlock/lift button as well as water spray for the camera integrated. I did not find the part number for this one so had to go with the standard.
- 7E0807151 - end cap to hold camera inside housing, £17 (ouch!!! vag charge rudiculous price for such a tiny part)
- wiring loom, got mine from carsystems.eu for 40 EUR, Kufatec also sell similar wiring loom
Carsystems don't supply install manuals with their wiring looms so I had to figure out the detail from various sources.
It's a bit cold over here now so had to also find a warm (and free) shopping centre car park.
The panel on the tailgate unclips more or less easy. A bit of insulation fell out when I opened it.
Applied some masking tape and cut a hole using dremel.
It is easier to cut the back line from inside. This can help you avoid scratching the tailgate from outside.
A bit of filing and filling the bare metail with automotive touch up paint of similar colour (the inside of tailgate is painted with a different colour
After a bit of drying, I put the camera parts together. Note the foam piece I had to cut out - even though I got all original parts, the camera was still loose after inserting the end cap. Maybe my second-hand camera had something missing?
Next got my new cable pull through out
and started pulling the wiring loom from the tailgate towards the front. For RHD it will be from the rubber grommet still on the left side of the roof.
I had pulled mine to the roof and left the rest to be done by soundproofers when they took the interior apart. Later took over the cable from the A-bar and used same pullthrough to get the wire to the stereo which I already took out.
I posted previously the pic where the signal pins go in the quadlock at the back of the stereo. Kufatec also recommend to connect the Positive and Negative at the back of the stereo as well as reverse signal under the drivers dash (carsystems wiring loom assumes you connect these at the back of the rear light) so I extended these wires to go to the front as well. The connection is done to Pins 17 and 8 for +/- as shown:
I noted this one as a good source of stable Positive to be used for other things later.
The last wire goes to the signal for reverse - it is in the white connector under the steering wheel, green/black wire, pin 12.
Carsystems assume you will connect directly to the reverse light at the back but I feared the PWM might cause troubles so I did the German way as stated by Kufatec so there it went to the front. Ironically, it might be the same wire that comes out from the back anyway, I haven't seen the wiring diagram so I don't know.
Coding the camera in two places using VCDS was simple for the first-time user.
Here's the final result:
Hopefully this will make it easier for others to follow. Good luck!
