OK, my pet subject as most of you regulars will know already.
Had my second Audi RS3 with 'official' AUDI brake-squeal-modifications over my pit today (don't ask) and the changes to this second RS3 are different to the first! I've said before that us owners are being used for development so stay with me here…
Car #1: This RS3 has:
1) New brake calipers and brake caliper mountings. The brake calipers are complete with 2-noise-damping bobbins per caliper.
IMPORTANT: these noise-damping bobbins are not intended to address the cause of the brake squeal, only the reaction i.e., the bl**dy noise you hear that is pi**ing OFF those who have it!
2) New brake pads.
3) New brake discs? No!
Note: this first car was NOT modified here in the UK but elsewhere; and I am not a liberty to provide the location other than it was in a financially viable part of the EU (so that rules out: France, Italy, Greece, Spain, etc.) However, this car retained its original brake discs (part number #8P0.615.301).
RESULTS: the owner reports that even with new brake calipers, etc., he still experiences brake squeal when braking typically at local supermarket speeds (5 to 0mph).
No authoritative advice from Audi but it may as well be: practice on-line shopping.
Car #2: This RS3 has:
1) New brake calipers (and brake caliper mountings) complete with 2-antivibration (noise-damping bobbins per caliper (actual photo).
2) New brake pads
3) New brake discs part number #8P0.615.301.B. Note the 'B' suffix, this is the later brake disc!
Note: this second car WAS recently modified here in the UK. I believe this car to be one of the first in the May 2013 Audi UK modification program. But it is NOT a RE-CALL as it is not a safety critical issue but will be applied as and when during the Audi Service system.
RESULTS: to early to say, but zero brake squeal at this time.
It frightens me that owners are being asked/told and/or made party to an agreement with Audi dealers (maybe Audi UK) to ensure they will NOT post/advertise details/results of this ongoing saga. BUT we're talking about AUDI here, not some Mickey Mouse company, but Audi.
My brakes do not squeal, as my own 'fix' remains effective!
Most owners/customers have spent (one way or another) between 35 and 50K on an Audi RS3 and these guys (Audi UK) are currently using a 'scattergun' resolution i.e., we'll look at your care if you promise (sign here) not to tell anyone else and if we do apply a 'fix' then (sign here) so that we know you’re a happy customer!
At NO time (even as I write) has Audi UK supplied a definitive action plan to resolve this issue.
A seriously GREAT car, but my marker is down that Audi/Brembo are now using owners to resolve/develop a resolution to Audi/Brembo brake squeal issues!
