Wrapped them gyuh

Mine keeps falling off … I don’t wanna do it TOO tight ?

Hi everyone, I’m rebuilding a 2014 Audi S4 B8.5 after an accident. The radiator fans run at full speed as soon as I turn the ignition on, even without starting the engine. I’ve already started and driven the car, and it doesn’t overheat at all. The car isn’t fully reassembled yet, and the A/C system is still empty (not recharged). Could the empty A/C system cause this, or is it more likely a bad coolant temp sensor, A/C pressure sensor, fan control module, or damaged wiring from the crash? Has anyone had this happen before?

Looking for some advice on a vibration issue.
Car is a 2018 Audi S4 (B9) on OEM Toyota Supra A90 wheels (255/35R19). The car is perfectly smooth with no spacers.
I installed 5mm rear spacers and now have a vibration around 70 mph. The spacers sit flush against the hub, but they have a slight amount of play on the hub before the wheel is installed. Once the wheel is mounted and torqued, everything is tight.
Could that slight play between the spacer and the hub cause the vibration, or is it more likely due to the limited hub engagement with a 5mm spacer? Has anyone else run into this with B9 Audis

Just pick up a 2014 S4. One owner with only 27k miles. This is my second B8.5 S4 and I can’t wait to start modding

Share this to people who want a good s4🙏🏽

Waiting on the weekend to put it back in. Gonna do Longtube,iabed adapter plate reroute prestone. Jxb driveshaft carrier. That will be already done when it party time.

Guys, I have a b8.5 s4. Have had it for about a year now.

Whenever I turn the wheel all the way and accelerate, I get a vibration. It almost reminds me of a truck in 4 wheel drive trying to turn.

Anyways, I haven’t been concerned as I took it to an Audi and they diagnosed it as “Quattro shudder” and said it was within the limits.

Now my question is, does anybody else have this issue? Or did the dealership lie to me? I am starting to think it could be motor mounts or something else. Please let me know if anybody has some insight on this!

Browsing Facebook Marketplace I found a 2014 S4 for sale 2 states away for $2000. I planned on a project car that would take years to complete, instead in 3 months I've turned it around to a full daily driver.

Since buying it I replaced the DSG ( used 2015 S5), the steering rack (2014 s5) all control arm bushings, tie rod ends, PCV, coolant crossover pipe in the valley under the supercharger, oil filter housing, valve cover gaskets, Catalytic converters are now CAP test pipes, secondary air pump. I did all the labor myself, the hardest part was getting the DSG coded to the car after it went into safe mode. Audi dealerships near me have a policy now of not touching cars over 10 years old. I found a dealership 3 hours from me that said they will support my car as long as parts are made with no up-charge for age.

I am now $10,000 in including the price of the car and my next steps are going to be CAP high flow cat downpipes, brakes, and suspension.

If anyone wants to see the entire process from the day I brought the car home having 0 clue what I was going to do, to finishing up enough to be my daily, I have a series of short vids on instagram: https://www.instagram.com/cajunb8.5s4/ I threw up for a few friends of mine.

No codes, no leaks, all checks out on computer, replaced ac pressure switch, expansion valve, compressor, disconnected the Lin connection, blower motor is working, hot air works. Any insight

I recently picked up a 6 speed B8.5 S4 and I'm absolutely in love with it but it has a terrible clunk coming from one of the front radius arms. I'm thinking of just doing all new front control arms while I'm in there, but I'm torn on what brand to go with.

What are some good options and some to avoid? I work at a shop so I can get wholesale pricing on Meyle, Delphi, Lemforder and TRW and I've always had good experiences with them on customer cars but I know 034 also makes some so I wanted to see what the consensus was with other S4 owners.

Picture for attention

Hi Everyone, I just bought a dual pulley setup off of Facebook marketplace. Not the smartest decision I know, but I’ve verified the crank pulleys size but I can’t seem to verify the supercharger pulley. I can’t tell if it’s aftermarket or OEM, and it’s not branded. It also had a part number but when I search it up it gives me mixed results.

The part number is 338534M. Someone please help.

Just picked up a b7 s4 avant 6spd, and i am so excited. it drives smoothly and handles on rails. However upon getting a muffler delete to hear the v8 rumble, my friend responded to my video saying it sounded odd or like a misfire. No CEL, and it drives well in my opinion. Revved to around 3-4k rpm and my garage was closed.

Does it sound right, or sound like it has a misfire?

Which oil do i put in my stage 2 Audi s4 2020

Mechanics say 0w 20 since it's recommended by Audi itself and he says that the pistons and everything is designed for 0w 20

Currently on 5w 40 and wanna continue with that

Living in Canada rn so it's around like 26 to 34c outside

Hi guys,
Right now, I'm running 255/35 R19 8J and I like how the wheel arch is filled out, but I'd like to switch to R18s 245/40 8.5J ET30 and I'm worried it won't look as good—specifically, that the arch won't look as full. I'd appreciate it if you could share photos with those specs.
Thanks

Hello guys,
I’d like to upgrade from my Rotor wheels to the ones in the picture—specs: 19-inch, 8.5J, ET30. Does anyone have this model installed? Do you think they’ll look good?

anyone have any idea what size the crash bar bolts are on a b8 s4. number 23 in the diagram

I have a B8.5 S4 and looking to get it tuned. Who are the go to tuning companies for these cars in the UK?

Cheers.

I found a shop here in Texas. That’s willing to work on the car but they wanna do an engine swap or replacement. I am 99% sure that that is not necessary. This car only has 105,000 miles. Car starts and sounds amazing. Just purchased so I haven’t tried to drive it yet out of caution. I am aware of repair cost and difficulty, and just replacing the timing chain. But that is what I want. I can give further details if needed. I’m located in DFW area, looking for somewhere or someone who is willing to do the work.
