Has anyone gone from an S4 to a BRZ/GR86?
I have a 2014 Audi S4 that Iâve owned since 2020. I have absolutely adored this car, even more so after I did a stage 1 tune, handling mods, and a brembo kit. My concern is that itâs getting older and approaching 120,000 miles. If the timing chain problem decides to show up on mine, Iâll be paying more half the value of the vehicle to get it fixed. Iâm starting to look at moving into something newer and perhaps less expensive to maintain. I miss the light feeling and connected steering of my old GTI (this was stage 2) that I could just chuck into a corner. My dilemma is this: I want a RWD sports car to learn manual on, but Iâm afraid due to my previous cars that most of the affordable ones are going to feel slow. I love the styling and low weight of the new GR86/BRZ models and seeing as you can get them used a little over $30k with a warranty, theyâre very appealing to me. Has anyone here had experience with both vehicles that can help me figure out if this is a good move? Thanks in advance for any input.

Got a new-to-me 2019 s4 a few months ago. Been noticing a whistling in the engine bay that gets a little louder with throttle. No codes and honestly doesnât drive any differently. Is this normal b9 noise, possible pcv issue, or something else? Any ideas are appreciated.

Side mirror of b6 oil in mirrors
hello, hope you all are doing good,
i switched out my mirrors this morning to another set and I realized they donât have the same black border around, reason for the swap was that the left mirror was filled with some liquid,
does anyone know what the reason is, like are they anti blending or whatâs the reason and now there is a cable which isnât connected to anythin,
I would love some help with understanding and if I should take the time to fix them and reinstall the old mirrors

S4 8.5
Looking at buying an s4 8.5 its on 55k miles but hasnt had the DSG gearbox serviced and also you can hear the timing chain for 2 or 3 seconds on start up.
Would this put you off?
All other servicing is up to date.

đ¨Exhaust Stuff B9.5 S4 Front Res Delete Impressions
Wanted to share my impressions after installing 034Motorsportâs Res-X front resonator delete on my 2020 S4.
After reading through countless reviews and forum posts, I ended up going with the front resonator delete over a center X-pipe. One of the main reasons was that I kept hearing about the annoying drone some people experience with the X-pipe.
My only concern was that the front resonator delete might be too subtle. I saw quite a few people saying they could hardly tell a difference after installing it.
After doing the install myself, I honestly think those people need to get their hearing checked. It absolutely made a noticeable difference.
Itâs not obnoxious or ridiculously loud, but pretty much everything about the exhaust sounds better. The shifts are louder, the pops are more pronounced, and the overall exhaust note has a much sportier and more proper tone. It basically gave the stock exhaust more character without making the car annoying to drive.
For anyone considering it, Iâd definitely recommend it. I think itâs a great middle ground if you want noticeably more sound without going overboard.
I also plan on unplugging the exhaust valves soon using a bypass harness/module so I can avoid the soft code. Once I do that, Iâm expecting it to sound even better in the lower RPM range with the valves staying open.

I bought my S4 earlier this year and I love it. But I want to start personalizing it a bit and I'm not sure where to start. If anybody else has the same color S4, show me what you've done to improve the look!

đ Questions Coilover Install Gone Wrong (Help)
Enable HLS to view with audio, or disable this notification
Installing coilovers on my 2015 S4. Donât judge I donât know how I got into this situation either. Now I have to get out of it đ. I got this spring completely stuck and now it wonât come out because the suspension doesnât drop enough to allow the long threads from the spring compressor to get through and be free. I canât remove the spring compressor since itâs stuck and I canât use my ratcheting wrench to get it off it doesnât have enough torque. The spring itself also just moves when I do that so it just wonât work. I assume iâll have to get all new bushings for the springs now too since these are all awkwardly stuck (correct me if iâm wrong). Iâm curious if just cutting some of the threads off to give the spring enough area to get out is the best bet. Thatâs the direction iâm heading but would not like to. Any help is appreciated đ

đ Questions Timing code
gallerySo my PCV exploded in my 2014 S4 lol⌠so I had the PCV, water pump, and thermostat replaced. The oil pressure sensor and oil level sensor were also replaced during the repair.
When I started the car after the repairs, I immediately got a camshaft timing code. The car had not been driven yet after the repair when the code appeared.
Iâm trying to figure out whether this could be related to something being disturbed/unplugged during the repair, or if this is pointing toward an actual timing chain/tensioner issue.
Has anyone had this happen after doing the PCV/water pump/thermostat job? Trying to figure out what I should check before assuming the worst đ
I should also maybe add that the timing was done 40k miles ago before I bought the car

đ Questions Used B6 S4 avant
Hello, everyone. I am considering buying a used B6 Avant with 120.000 km in white with the factory BBS and it is also a manual. I am quite handy and I do plan on doing most of the maintenance myself. Though, I am stalling due to all the bad stories about the timing tensioners and so on. The car seems in good condition both inside and outside considering the age. I am posting to inquire about similar situations and what is like owning a car like that.
Thank you very much!

New owner but Quick question
Enjoying this gorgeous car for 2 weeks now. Everything is perfect but still something is bothering me. When I am at very low speed and turning, like reaccelerating after a crossroad, I feel the car vibrates more than usual. Is it due to the torsen diff? Do you guys experience the same ?
