Sounds like the brakes are not fully coming off the pads when going into reverse

Then lift off the brake but not all the way and allow the car to pull into wherever I am reversing. Modulating the brake as I go, and of course, getting the noise. So in no point during this process have I really left off the pedal.

Tonight, I did exactly the same but lifted off the brake completely, dabbed the accelerator (which was actually quite voracious for the fact I just touched it) then went back to just modulating the brake pedal. The noise stopped! I'm going to try it again tomorrow. Not wanting to get ahead of myself as it could have totally been a one off but... could touching the accelerator release the pads further from the disc and thus, eliminating the issue. :?:

Wondered if anyone else does what I does and perhaps could try and instead, come off the brake, tap the accelerator and then return to just using the brake for control.

Cheers.
Yes, I’ve tried that as well. When applying slight brake pressure the resonance is noticeably louder than when I take my foot off the brake and allow the car to reverse at idle speed. I only experience the noise first thing in the morning. Reversing later in the day makes no noise, even after car has been standing for some time and disks completely cold. I was going to remove one of the wheels and take a look myself at the pads and check for any extraneous play in the calliper. However, now VW appear to have a solution I’ll wait until the first service in about three months. Hopefully by then word may have filtered through to the dealerships.

Based on post by deanjesper, bottom of page 8, VW has put it down to a design issue with the pad.

I was in VW Monday and they said there is no new declared fix by VW factory.

I was told that there is a software update for the abs module but that was it, no mention of pads being the issue. I already have the latest update.

Nope because I still have the mooing noise even with the update.

Ok, just so you know I had my discs and pads replaced last year and the noise returned within a couple of weeks.

Hopefully you are luckier than I..
