WHEEL CRACKING

[danilobandeira]

Hi
I have a problem last year with my car.

I was on a track day and after a turn, my car lost control and went outside the track.

And my wheel broke some "sticks".

I fired audi in justice and paid for an expert to analize my wheel.

Because for me, i dont loose control (human problem). I absoluty think that the wheel crack/broke and i lost control.

Mt lawyer is arguing that the wheel didnt support the pressure.

Why that? Because if you look the wheel, you cant see any "stroke/hit" at the wheel.

And today i saw some pictures that valentino rossi suffered an accident with his rs6 and the wheel broke as mine.

MY CAR:




Valentino is those ones:

Nasty another nail in the coffin for the 21" wheels
i hope you were unharmed

On the upside, you can tell everyone in the pub that you push your car as hard as Valentino Rossi does. Cool.

[RS6chris!]

Oh dear


What other damage to car?

Looking at the color of your calipers, you have been pushing the car a lot at the track, the goldish discoloring is a give a way and means this wasn't a one time only. Not blaming you and the way they should be driven....but sadely i'm affraid this heavy car isn't a track car and looks the wheels 'finally' cracked under the heavy load (metal fatique). If i read how many have bend wheels, looks the wheels are of poor quality for this heavy car.
Wondering if the spoke design dual 5 spokes are to blame over the PE wheels for exampe that have more spokes and more evenly sprayed across the wheelcircle :s.
Hope you get it sorted, but i'm affraid only lab tests will be evidence enough to make a claim .

Another possibility is sudden tyre pressure loss, meaning the car is effectively running on the wheel rim, which then caused the wheel failure?

As above, hope the rest of the car is okay, the plastic side sill looks to have take a beating, did the disc + caliper survive? Hope the recovery truck didn't do any more damage dragging you out

[danilobandeira]

Everything is ok.
Only wheel, front pumper and two coolers/filters close to the right wheel (under)

Ian_C, i thought in this possibility. Tire pressure, But, how the whell cracked? Because i didnt hit anything with the wheel.

Dasquade, they test every car in the tracks, especially nurburgring...
A car with 560hp, the brake rotors with almost 19" and ceramic brakes. Sorry, it MUST resist.

I know they do some intense circuit tests, but was wondering how many km's yours had been at the track? Don't get me wrong, just trying to help find reason why it broken. Imho it is a design of the wheel and metal fatique caused it to snap.
It does look the wheel got a big side impact (dirt marks)...

Wow, i don't think i've ever seen a wheel on a modern car do that.

I'd be surprised if purely pushing hard could cause that unless the wheel was flawed in the first place. That said if you use it extensively on track & you like to push on, i'd imagine a few curb clippings could weaken a wheel enough to cause that kind of damage.

I agree.

This is an RS6. It is pretty much the top of the Audi tree of RS models which are marketed on the mantle of being FAST.
It weighs 2 tons and has 600bhp to put through 4 contact patches.
It has a 3 year warranty with a fair expectation that the parts enabling this performance can take some punishment.

Audi is a premium brand not a budget mark and so also comes with an implicit promise of quality.

Whilst I realise that tyres and brake pads are consumables I do not count a wheel in this category.

I am not commenting on individual circumstances but I know mine had 3 eccentric wheels and had never seen a track. This happened around 8000 miles and 9 months. I have a reasonable expectation of the 3 year period passing. Will they buckle again within that period.

10, maybe 5 years ago, but they aren't premium anymore. Not that is an excuse, clearly there is an issue, potentially a dangerous one. VAG is clearly in a mess, dieselgate is going to rumble on. They are not going to want to cough up for anything unless they really have to. I'd imagine warranty claims are being highly scrutinised.

I'd imagine warranty claims are being highly scrutinised.

Especially ones that could progress to class-style recovery or recalls. It's easy to forget that this very webshite was created from nothing out of Audi's previous wheel defect masterpiece, the B5 RS.

You need to get out and drive some real world, everyday cars. They're still premium, just come with more niggles nowadays.

Abso - bloody - lutely. To say the C7 RS6 is not premium compared to previous iterations is utter rubbish. It's much better in every department (except perhaps number of cylinders). Remember the wheels on the B5? I won't forget them

I do think there is an issue with the 21s though. But everyone makes engineering mistakes.

You are confusing brand and product. The product may have a whiff of premium, but the brand definitely doesn't. A truly premium brand would have dealt with this wheel fiasco.
