Hello everyone,

This is my first post on this forum, I hope you're all good!

I have just bought a 2005 B7 A4 Avant 2.0 TDI S Line and there are a couple of things I'll need to sort out on it.

One of those things is one of the buzzers/speakers for the rear parking sensor is on the way out and sounds horrible. I think there must be two buzzers/speakers in the system because the beep as you select reverse gear is fine, it's the beep that happens as you back up against an object that sounds nasty.

I've followed the sound to the panel on the side of the boot interior but haven't yet started taking up the trim to investigate further, because I thought it best to post on here first to see if anyone has replaced one of these before and has some do's and don'ts for me, and hopefully a part number!

Anyone here have experience of this please?

Cheers,

Jon
