3) Answered myself. There is no position to the rear left speaker for the buzzer.

Another question is if I could use the same buzzer for both rear and front sensors splicing the required wires.

1) Yes the provided tape is strong, just make sure to clean the area well first. I scored mine with sandpaper and it's been fine since

2) You can either go down the centre console, or down the rear side panel and sill trim, just preference really

3) I think the main reason you'd want the sensor in front of you is so it sounds like the beeping is coming from in front of you. Having all the beeping coming from behind might feel odd

4) I wired mine as in the first post and according to Elsawin, but it does seem to work without the extra power wire as IPG proved. Elsawin is often wrong, unfortunately...

Regarding:
Pin 1 > Fuse 7 in dash fuse box (5A) (positive, ignition live)

Do you remember if you used 0,35mm thin wall wire?
In wiring diagrams is 0.5mm for ignition live. I think that does not matter but just asking.

Sorry but I can't remember. I use the thickness from Elsawin so if it says 0.5mm I would use that

That looks like a pain to get to! It access easier via removing the instrument cluster?
 
It is not reachable through instrument cluster.

A friend proposed a trick to splice into can high and low (he found this trick from his trailer), which was really useful.

You use an extra 2 or 3 pin connector like the one in the picture below
98A4F929-A746-4623-BD47-89E8A8520E93.jpeg


You unpin for example Can+ and you pin it to the connector. From the other side of the connector you pin a double wire into a single pin. One wire goes to the gateway (where we unpinned Can+) and the other one goes to the accessory we are adding.

In that way, it is reversible.

Regarding the retrofit, I am almost done.
I am waiting for 2 straight sensors to drill and put them in the front bumper and I hope will work.

Sounds like a good way to do it
 
Completed this mod today.
Most difficult part was to drill and cut for the outer two sensors of the front bumper.

If I was doing it again, I would bought the drill tool proposed in the first post.

Some points:

1) Rear bumper was very easy to fit the sensors and wiring. Plug and play.

2) No need to use positive from the rear fuse panel.

3) I removed the headlights to remove the front bumper. You can easily access the two required hexagonal nuts.

4) For the front sensors I bought a loom from A4.
AUDI A4 8K B8 1.8 TFSI 2008 RHD Front Parking Sensor Wiring 8K0971095A 12511081
It fitted perfectly.

5) Can gateway was located under the steering wheel. See the picture in a previous above.

6) I couldn’t code using obdeleven. I used VCDS from a friend. Obdeleven doesn’t have “installation list” feature or I don’t know where to find it.

Next are rear and front camera along with a 9”inch monitor.

Good job 👍 yes I'd definitely recommend the punch tool as it gives a nice OEM finish to the holes too

Interesting that the gateway was under your steering wheel, so basically it's always on the left regardless of the steering wheel

It was superseded by H which does support OPS but that doesn't necessarily mean D does

FYI H, N, Q support OPS definitely

So, I've done this as a retro it and its amazing, took ALOT of wiring, in conjunction with fitting the rear boot handle and the reversing camera. One thing I noticed was that I was getting a 'Disruption to communication' error on VCDS within the Navigation and Radio modules and I couldn't get the OPS working on screen!!

Turns out it was the CAN gateway!!!! I had a 'K' version on my 56, V6-3.2......so after looking at the image of @MT-V6 Can Gateway, I bought an 'L'
version as attached and TADA!!!! all codes went and the OPS image appeared on the screen, now everything works perfectly!!

Thought this might be helpful for anyone trying this Mod and finding the same faults that I did, which took ages to figure out!!
 
Some more info.
Total Cost of the parts was 300€.
Here is a drawing I made to help me.
As I have a buzzer sitting around from when I thought my existing one was at fault (wasn't I simply forgotten to plug it back in) I have started shopping for the rest. The A4 front harness is en route as we speak. The wiring diagram will be a great help and thank you.
