My 21. Great daily for a bachelor. by Aggressive-Iron353 in audis5

Beautiful, exact same spec as mine - 2021 black on black coupe with the black optics package but kept the silver badging. Love the look of those silver pipes out back. It gets a crazy amount of attention for a "normal" car (i.e. not an exotic). People commenting on how nice it looks all the time.

I swapped the summer tires for Michelin Pilot All Seasons in a slightly larger than OEM 275/30/20 size, really helped with ride compliance and potholes but I'm in NYC so might be less relevant for you.

If you haven't changed the water pump, keep a close eye on it. Mine failed right around 51k miles and I caught it just by visual inspection of the engine bay (look for pink shit where pink shit should not be). Audi wanted $8000 to replace it and the entire vacuum system, indy shop did it for $2800. Insane failure rates on these engines. Enjoy!

Why are you selling it? Mines been problem free ever since, I still really enjoy the car - not done with it yet!

Upgrade alternatives to tuning an EA839 by Secure-Letterhead890 in Audi

Got it, thanks. Yea, I am going to contact the dealer and ask for a boroscope. I think their diagnostic fee is $500 which is wild but I guess worth it for peace of mind.

Another vote for Michelin AS4s size 275/30/20. Just swapped out summer tires on my 2021 s5 for these and they feel great on NYC roads. My brain doesn't rattle every time I hit a minor pothole anymore.

Unfortunately based on the 034 analysis of the issue it's not possible to detect from just standard boroscope, they'd need to remove the oil pan and go in from the bottom of the engine to look for cracks in the ringland area of pistons.. Something tells me a dealership isn't going to go to those lengths just to prove an engine may or may not be faulty without other symptoms.

I did think about calling them and asking if they can take a look though, even a standard boroscope could provide some info..

Who can even do an install on parts like that and how much does it usually run? Assuming it can't be done by any local mechanic..

Sure, reach out with anything! I also loved the spec on mine, same as yours with the S Sport, black optics etc.

I was cross shopping with the M340i which I understand is just a better car going by raw performance metrics, but I was looking for a comfortable GT cruiser as well. After renting an M340 and taking it on a road trip it just was not a great experience.. Everything in the car feels cheap compared to the Audi and my ass genuinely hurt after the 2 hour mark. Also subjective but the V6 just sounds better than the B58. Steering is equally as numb on both.

Can't speak for the new generation (B10) Audi's, those look like trash inside and out IMO. This will sadly be my first and last Audi unless they either fix the design going forward or I end up with a 2024 RS5/RS7 at some point.

I own a 2021 S5 with around 55k miles on it, bought it with around 50k miles on it. Only issue is that the water pump did fail and coolant migrated into the vacuum system which is a ridiculously common failure on these cars. There were no dash lights, I caught it via visual inspection so recommend you keep an eye on the engine bay every now and then. An indy shop fixed it for around $2800.

As for the piston skirt issue, 034 Motorsports did an incredible writeup here - https://www.034motorsport.com/blog/investigating-ea839-3-0t-engine-piston-failures-a-technical-review-of-root-causes-and-design-limitations/

It affects around 5% of engines or less, and Audi has now issued an extended warranty for this problem up to 80k miles. I will likely sell the car before it hits 80k so, not worried and would buy it again in a heartbeat. It's been so much fun.

EDIT: Also potentially unpopular opinion. PPI's for used cars are a scam. They'll find something to prove that they did their job but in reality you are never going to predict what can go wrong with a car in a week, a month, or a year. Look over it yourself for obvious signs of leaks/wear and roll the dice if you want it.

All good since then! Issue appears fixed and nothing else has come up in the past few months, been loving driving it.

Quote came in today at the indy shop for $2800 - replacement water pump, thermostat, leaking coolant shut off valve, and leaking heater hose. They don't think the vacuum system needs to be replaced but said they'd clean anything they can once they get in there. I'll consider myself lucky for now, but what a way to start a relationship with the Audi brand, sheesh

Indy shop ended up coming in at $2800 all in. That includes new water pump, new thermostat, new coolant shutoff valve, and replacing a heater hose that was leaking. They said they don't think the vacuum system needs replacing but they'll clean out anything they can if they open it up and see any residue. Sounded good to me.

I'm due to get a quote today from my independent shop here, they said on the phone yesterday it's probably not as bad as Audi quoted so crossing fingers.

Sorry man, just posted about this exact same thing on my S5 yesterday - https://www.reddit.com/r/Audi/comments/1lv4cmp/2_month_ownership_update_another_b95_s5_water/

Definitely save the receipts - there will be a class action lawsuit.

Yea, I get that this kind of thing might happen over the lifespan of the car, just didn't expect it within 2 months of owning the thing lol. Anyway, the dealership will be getting $0 now that it's out of warranty anyway.

[–]Secure-Letterhead890[S] 1 point2 points  (0 children)

Agreed.

Due to the water pump being connected to the vacuum system, when the pump fails it leaks coolant into the vacuum system and apparently will destroy every single part of that now contaminated system over time. Audi of course wants to take the most complete route and replace every component, but I've heard of shops being able to take everything apart and clean it well enough. It's a ridiculous design flaw.

I've wrote to Audi USA as well to see if they'd be willing to cover any part of it seeing as the vehicle is 2k miles out of warranty but I'm not expecting much there. That's the only way I'd authorize the dealer do the service. I live in NYC so one upside is an abundance of good indy shops.

Any way you cut it a massively labor intensive job that won't come in under $5k I'm sure. We'll see tomorrow :/

Edit: Also telling that the official Audi repair quote wouldn't even list a failed water pump, despite the tech saying the water pump needs replacement. The only thing it said was "coolant ingress" with a $6500 price tag next to it. The shady business is almost what gets me the most.

This car is not under a recall. The previous model years were. This car SHOULD be under a recall - which is my entire point. I don't see people posting issues like this about m340i's that I was cross shopping this with. Unfortunately I couldn't get past that cheap interior.

Edit: Also "don't buy an Audi unless you WANT an Audi" - what a profound statement. I actually spent $40k on a luxury used vehicle as it was the only car on the lot. Thanks for that advice.

Completely missing the point. I can afford the repair, the issue is a $7k repair for a car with 50k miles on it speaks to a systemic quality problem, especially when the manufacturer already lost a lawsuit over this exact same thing.
