rust advice

[FLYNSHU]

Hey, any experience with rust and how to fix this? I'm concerned that it will come back after I fix it. And anyone get this covered under warranty? Isnt there better technology to prevent this on luxury cars these days?

What year & model. The A7, S7, and Rs7 have aluminum on all to the body panels except roof and rear quarters. I'm guessing this is the rear quarter. You must inspect your sub frames front and rear for heavy rust. My body panels were fine but the rear sub frame was very terrible and I seemed to have the only 2012 A7 with this rust condition. I spent weekend applying special black rust reformer that uses a tube to spray inside and outside the subframe.

Since 1990 Audis pretty much don’t rust. The odd car seems to have it or any that have been in an accident and the damaged panel wasn’t fixed properly.

I had rust on my 2006 A6 because the 18 inch wheels were so close to the body, it sand blasted the paint off the leading edge of the rocker panels, plus here in Canada they were putting down salt on the roads.

I had the same car fixed and they said they had to zinc coat the panel before they painted.

The galvanizing is pretty good. I bought a 3 year old 1998 A4 with a stone chip and a small bit of orange rust in it.

In 11 years of ownership, the rust in the chip barely grew in size.

My friends 2006 A4 is doing what yours is, but he never fixes anything. He drives until the tick become a click, the click becomes a clunk, the clunk becomes a thud, the thud becomes a bang, the bang becomes a boom and when the car doesn’t move, then he calls…

Its a 2012 A6. And yes, rear quarter. Sorry for my ignorance, but what does my subframe condition have to do with my body condition? I dont think my subframe is rusty but I cant say for certain. Did you have rear quarter panel rust like mine?

Ya thats partly why I'm frustrated and confused with this rust. This car is in showroom condition, and I bought it as the 2nd owner from the dealer straight from the manager that I knew personally. He assured me of the whole history of the car. I've now had it almost 6 years and never any accidents.

I know we use salt here in Edmonton as well, but I rinse it off multiple times a week in the winter and park in a heated garage.

What did it cost to get yours fixed? I'm trying to decide if I want to keep this car for another few years or get rid of it now before this problem gets bigger.

If you have damage on the side panels seems likely you might have rust elsewhere such as the steel subframe. I have zero rust on any body panel and the under body, but the rear bolt on subframe was completely orange rusted on mine inside and out. My A7 car spent 9 yrs of it's life in Manhattan NY.

Since the rust was on the lower rocker panels that have bumpy duragard on them, the job was not critical to be flawless.

I did bring it to a top notch paint shop that does better work than even the Audi dealerships contractors. They charged me $280 for both rockers and gave lifetime warranty.

For your car, most likely they are going to remove the rear bumper cover and then paint a much larger portion of the car to blend it in.

Bonus is it it white, which is easier to blend. Not bonus is if you are OCD, you just don’t want a repainted car, period.

Thanks. I'll have to start looking into whether Audi will warranty this but I doubt it based on what I've seen in posts thus far. It seems to need to be "all the way through, from the inside", which I dont know how close mine is to that definition, but it might be close since it's bubbling. And yes, my OCD will kick into high gear when it comes to paint given I'll expect to have the whole side be painted to blend flawlessly. I had a car door blended many years ago and it looked terrible and it was all I could see on the car after that lol. I appreciate your input.

That's what Audi told me, must be rusted all the way through for it to be covered. Metal needs to look like swiss cheese basically. Based on where my rust was on mine, it was too dangerous for me to wait for rust holes.

Good luck, won't hurt to ask them for warranty coverage.

Yeah Audi is rather notorious at not honoring their rust warranty.

I believe it's 12 years warranty too, so it's unlikely you'll have through and through rust within that time period. You also can't have any paint work done it that's not by Audi or it won't be covered either, they will blame the paint job. So you have to leave it until it gets really bad...
