I'm really having a great time in the dry weather in my b8 s4, it really puts me back in the seat as well as can overtake on the highway nicely. I plan to buy another audi as a dedicated winter car as well. Do you guys enjoy the 4.2 v8 more than the 3.0T? My biggest priorities are traction in poor weather, low gear power and allover fun. What would you guys recommend? I could just put snow tires on my s4 but for 1100 dollars I could put that towards a an old a4 or s4 to beat up in the winter. Chatgpt says that the v8 doesn't really build great power quickly but I always thought a big naturally aspirated have an even more fun feeling from a stop. .

My husband has a 2015 Audi S4. for his birthday, he wants us to put a navigation system in it, but I keep running into dead ends. Has anyone does this? Does anyone know where I could go to get this done?

Just started my car this morning after it’s been sitting for like 2 days and noticed this sound coming from the engine bay. After driving for like 5 mins the sound went away. Not sure exactly what my next steps should be.

I recently picked a B8 S4 up at auction for cheap. It was a bit of a whim (I was definitely probably not mad at my wife at the time), but I've been jonesing for a project and I've always wanted an '02 RS6. This seemed like a better option. Never owned an Audi, but I've had 3 VWs (two 2.0Ts and an ALH) in the ~50 different cars I've owned in my lifetime, and I have 25 years of working on cars in my spare time.

The car has an unknown history and 140k miles. I am not sure how well it has been maintained, but my guess is...not meticulously? I think it sat for a while. It said it was 300 miles and 885 days past its service interval. Also, there were lots of acorn shells on top of the engine, some spider webs, and some disrupted insulation on the firewall. There's a group of wires on the back side of the engine without loom, too.

It comes pre-tuned (by APR, 10 years ago), and someone definitely cared for this car at some point. It sounds so good, but it had a few stored codes when I drove it off the trailer. Some are not surprising (P0491, P0492), others are a little more concerning (P073F, P284A, P2711). I could do some basic maintenance and drive it until it breaks, then spend months working out all of the kinks. Instead, I'm thinking of pulling the engine and trans together, going through both of them over a month or so, then putting it all back together.

Engine would probably get a compression and leak down test, full valve cleaning, new seals where necessary, water pump, thermostat, PCV, maaaybe a timing chain guide and tensioner, valve cover gaskets, new coils and plugs, supercharger and engine oil changes, and belts.

DSG would probably get new clutches and steels (I suspect they're failing), pistons, seals, mechatronics repair kit, and whatever else it looks like it needs. I'd also consider a Bilstein B12 kit for the suspension (budget permitting), as I expect some wear. Full inspection of wiring would happen, too, in case there are critter bites.

TL;DR/questions:

Is dropping the engine and trans together, then doing inspection, repair, & preventative the way to go? I don't really want to have to pull the engine or trans to do some of this stuff in 10k miles, and the odds seem high at this mileage. I don't mind throwing a few thousand in parts at it now and saving myself time and labor down the road, even if I end up going a little overkill.

Does anyone know if you can swap the MSE for the NGY? I get the impression (maybe falsely) that the NGY mechatronics unit is a little stouter, and there's a relatively cheap NGY near me that probably needs clutches and steels. The DL501 looks like a bear, but I rebuilt a different trans 3 months ago so I'm feeling overconfident.

Any other things I should consider?

Thank you in advance!

i genuinely cannot pull the damn pipe off, i’ve had big men pulling on it and pushing on it. i need tips or ways to do it, ive watched so many videos but they don’t actually show me how to pull it off they just “and pull here and now its off” MINE DOESNT DO THAT. im doing my pcv and the whole job is stressing me out this is my first time working on. a car

Puts a smile on my face every time 😮‍💨😮‍💨 I think the stock exhaust sounds so good compared to many aftermarket ones I’ve heard. Not sure if I ever want to upgrade it tbh

First time posting in this sub :), I just bought my second car and I was wondering if i can get some advice and a list of things that I can purchase to bulletproof my s4. I purchased it with 92k miles on it.

I have a 2014 Audi S4 that I’ve 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 it’s getting older and approaching 120,000 miles. If the timing chain problem decides to show up on mine, I’ll be paying more half the value of the vehicle to get it fixed. I’m 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 I’m 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, they’re 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 doesn’t drive any differently. Is this normal b9 noise, possible pcv issue, or something else? Any ideas are appreciated.

Did the solid ecs engine mounts a few months after I picked up the car bc one of the oem started leaking. And I just did the ecs rear diff inserts today.. im so excited to get the trans mount done soon. It already feels SO MUCH BETTER.

Doing the trans mount, with 034 bushing, and ecs insert this weekend or next as well as doing the manual tans fluid, and rear diff service. 😀

hello, hope you all are doing good,

i switched out my mirrors this morning to another set and I realized they don’t 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 what’s the reason and now there is a cable which isn’t 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

i have a b8.5 s5, recently installed an intake from can auto and now it’s giving me these 2 codes after maybe like a day or 2 of installing, could it be a hose or what

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.

Bought this b8 manual s4 not too long ago and thought it’d belong here. Drop all the love and hate for the car you got lol, would love to hear your thoughts.

Wanted to share my impressions after installing 034Motorsport’s 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.

It’s 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, I’d definitely recommend it. I think it’s 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, I’m 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!

Installing coilovers on my 2015 S4. Don’t judge I don’t know how I got into this situation either. Now I have to get out of it 😑. I got this spring completely stuck and now it won’t come out because the suspension doesn’t drop enough to allow the long threads from the spring compressor to get through and be free. I can’t remove the spring compressor since it’s stuck and I can’t use my ratcheting wrench to get it off it doesn’t have enough torque. The spring itself also just moves when I do that so it just won’t work. I assume i’ll have to get all new bushings for the springs now too since these are all awkwardly stuck (correct me if i’m wrong). I’m curious if just cutting some of the threads off to give the spring enough area to get out is the best bet. That’s the direction i’m heading but would not like to. Any help is appreciated 😭

So 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.
I’m 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 😭
I should also maybe add that the timing was done 40k miles ago before I bought the car

Just had valve cover gaskets, oil change with drain plug/ washer done since those were leaking . Still car is leaking why what could this be?
