Who has had problems with warped discs on their RS6 C7?
I bought my 1st used Audi RS6 C7 March this year with 12,000 miles registered. After 3,000 miles I suffered severe brake judder as experienced by car magazine in their Feb 2015 addition as below:

Month 3 running an Audi RS6: the brakes grumble
At around 2000 miles, the RS6’s brakes – standard discs, not optional ceramics – started juddering. This wasn’t a wobble, it was a brake-disc earthquake. I hadn’t been on track, nor driven particularly hard. Odd.
The great thing about having a new car is that problems are taken care of, but it’s the hassle, the calls, the disappointment that your car has broken. I called Peterborough Audi. ‘Don’t drive it,’ they said. ‘Call Audi Recovery, get it recovered to us. We can give you a web-link to watch our technicians check it over.’
Audi RS6 engine: providing the fireworks
I just knew that the technicians would love me remotely watching them, so I said ‘great.’ It would have been greater if they could’ve just dispatched Audi Recovery, but still… they answered promptly, offered me a hire car and took the RS6 away within hours. I never did get that web-link, but the verdict was quickly in: ‘new discs and pads’. The RS6 was soon returned, fully valeted.
‘We haven’t heard of this issue,’ said the Audi manager who delivered my car. ‘But Audi will want the old brakes back for inspection, and if there are a few cases, you can bet there’ll be a recall.’
I asked for a full report but, two weeks on, I’m still waiting. Any RS6 owners with wobbly brakes? Get in touch.

At that time my local dealer replaced the discs & pads under warranty.
Great I thought, until 3,000 miles later & the same problem returns! This time my local Audi dealer refuse to replace under warranty!

Sent an email to Audi UK customer services, who after a week also refuse to replace under warranty!

Any one else had similar problems? If so please get in touch.

Thanks for looking,
Dave.
