r/AudiRS3

Has anyone done this coding recently to 2026 model? I’m in U.S but I see there’s a drastic price difference between ACM Technik and Europrice. Euro is showing over $2000 vs ACM $600. I know there is a complexity with SFD2, cable alone is $300 from Europrice I wanted to know why the other is way cheaper and obviously I’d rather spend $600 than $2100.

Live in the Dallas area, we rarely see snow, but during the winter, we do have brief periods where the temps drop below freezing for extended periods which could cause summer tires to crack.

With my Golf R, it was easy to purchase a second set of wheel/tires with a square setup with all-seasons to use for 3-5 months out of the year.

.

Not a fan of having the tire shop removing/installing tires on the stock wheels twice a year, so what are you guys doing for wheels and tires?

I noticed the Audi winter wheels are 19x8's, but different offsets front and rear, why? Does a square setup not work on the RS3 like an S3 or Golf R?

So I got a 2019 stage 1+ rs3 on bilstein b16. I will tell you what to not upgrade to is the g80 m3. Thing was not as fast as I thought it would be and felt extremely bloated and is definitely not worth the nearly 50k price difference. Any tips that aren’t Porsche? I’m down to spend up to 100k but for me to spend that it’s gotta blow my rs3 out of the water by every metric

NEEDS AWD

Where can I find the highest quality paddle extentions for my 2017 RSQ3?

Like the title says is it worth it? I think the filter runs for about 50 dollars and if it makes the turbo a bit louder I think at least to me that it’s worth it. If you the have filter let me know what you think. Thx in advance

Hey guys, 2018 8V owner here. Noticed that while my car feels good, and acceleration is smooth, boost gauge moves all around during a pull and doesn’t ever hold max when foot to the floor. But it doesn’t feel like it’s breaking up.

Other than that it runs well, no codes, good mpg. Completely stock with a stage 1 ape tune (that i thought would sort this out). Other info I’m in the Deep South so it’s 100 out with 75% humidity.

Could be heat soak maybe?

I’m doing the bare minimum and swapping the wastegate line and getting it tested for leaks. Any chance it could be timing chain/timing related?

Any suggestions appreciated.

Just got 26 RS3 with dynamic package that has the HP summer only tires. Living in the North East it means that I am going to need another set of tires before Christmas. We don't get enough snow where I would bother with dedicated set of Winters and really don't feel like having to do seasonal wheel swaps.

I am coming from at mk8 GTI autobahn that came with 19in summers and I put on a set of Conti DSW06+ which I really liked and were super popular on the GTI platform.

Wondering what are the popular choices for the RS3

Looking for advice for winter wheels/Tires for my 2026 rs3. Looking at oem package or buying some apex vs-5rs. Would likely do the 18×9.5 front and 18x9 rear. Would like to run hakkapeliitta r5s but only come in 245/40/18s. So Would have to run square tires or get another tire - michelin maybe? Oem package has pirelli winters - any experience? Anyone have suggestions? Thanks

Any recommendations to have midpipes installed on a 2023 RS3 in Chicagoland? Audi Hoffman Estates seems to be an authorized APR dealer. Maybe they would do it. And might give me an excuse to get it tuned and have them fix any warranty issues before my warranty expires.

Thoughts on the value of the rs3 once it discontinues next year? Also the 2027 refresh interior looks horrid so is the 26 the last best rs3?

My 2019 just had a Cooling System Malfunction pop up about 2 min after start up. Coolant reservoir was fine and I have not added any coolant. Drove the car and it did not overheat or misbehave. No coolant smell in the engine bay either. Sound familiar to anyone?

I have a new RS3 with around 2,000 miles wondering if an intake would cause me warranty issues if something ever happened. Just wondering
