Hi all I bought a 2015 RS3 in 2018 without being aware of the issue with the wavey brake discs (hindsight is great!). Since owning the car I have had two sets of front brake discs replaced by Audi, both started warping just after 3,000 miles. Luckily Audi has replaced both them both times as gestures of good will with the same disc versions (8V0.615.301.C). They are warped again (yes after 3,000 miles!) and this time it is not surprising that Audi are refusing to cover the costs. I am not an expert and any help would be greatly appreciated, would be great to know whether Audi have solved the problem with the latest discs which are now round and not waved (8V0.615.301.S). I am happy to work with Audi, but to deny that there is a problem with the original brake design is rather sad but not unexpected for such a big car manufacturer. From reading this very well covered topic the issue is to do with the vanes not being directional and that as the RS3 doesn’t have a true LSD so it uses the brakes to compensate, which causes one side’s disc to overheat, and with the standard OEM pads a lot of brake dust is generated which ends up deposited on the disc and warping. If I was track day driver or someone who drove spirited with daily driving I would expect this and would have purchased upgraded discs/pads. But I am not, am more of a mid life crisis man who just loves his cars and appreciates what the car is all about! Personally I love the RS3, it's an amazing car and brilliant build quality, it's the perfect everyday car. If the newest version fair no better, I am considering replacing the Audi discs with the set produced by Alcon/Revo (RA551B200600) hoping they have solved the directional blade cooling issue. They do look the part, just need to match with the correct pads, so any advice gratefully received! Thank you very much for reading and thank you.
