this instruction is incorrect for Sedan, in a Sedan, the buzzer is not on the left seat belt guide.(not on the right seat belt guide either). this is from first hand DIY experience.

Thanks from this side of the pond.
 

Cheers guys, picture really helpful too.

Thanks ... Andy

Audi A6 - Sedan (from 2004) rear parking sensors buzzer location
 

Dear Forumers!

I tied to find my buzzers location, because I had the same issue: not working.
I didn't find any answer, so I started to looking for it and finally I succeed! So that's why I try to help.

My car is an Audi A6 Sedan (first of the 2004 serie).

After 2 hours I found it: on the driving side, back seat, under the belt holder. The main problem was, that is not actually under, but on the side of it. So there is (behind the C-pillar ) the small window (little triangle). The buzzer is simlpy dropped there (between the cars metal wall, under the triangle glass), sticked to the outer side of the belt cover.

I deeply sorry, but I foget to make picture the exact location, but hope you understand that. I made 2 pictures (when you able to reach the buzzer, I simply pulled out it's place, so tried not to rid all of my cars parts). However you need to remove the fallows:

- cap holder
- the screw what holds the movable seatback (remove the side)
- C-pillar - has 2 screws, one under the seat side, one under the uper end of the pillar, able to open it with little force (its a patent fastener) (whit this, the belt cover starts to move)

I forced my hand under the C pillar and grabbed it.

Finally, sorry for my english, that is not so good, but hope I helped...

Step by step photos and location
 

I've just did the replacement. It was a long process looking for the horn. But I finally found it and here are the step by step photos. I think the horn is always located behind the left rear passenger seat belt winder, just inside the C pillar window. You also need Torx screwdriver no. 10.

1. Remove the rear central trim to access the screw to the C pillar's upper trim, by carefully pulling the clips. There are four of them.

2. Remove the C pillar's upper trim as shown below. There are one screw and two clips.

3. Remove the bolt for the left rear seat fold down latch, as shown below. This will allow you to move the cushion.

4. Loosen all the screws for the triangle shape trim for the C pillar. There are three screws in total. Two at the upper trim and one at the bottom, hidden behind the cushion (refer to no. 3 above). See the location of the hidden screw in the following photo.

5. Now you can remove the triangle shape trim, which also covers the seat belt winder.

6. Once seat belt cover is removed, you can access the horn as shown below.

7. Then it is just a matter to put everything back together. Remember to test it first before putting everything back together.

Good luck.

Thanks, excellent instructions.
 

:) Cheers, I've already done this job but a great step by step guide for the next person!
