Today we have the NEWEST engine we've ever had on the channel. This is the CWGD/EA839 3.0L Turbo from a 2022 Audi S5. This engine suffered a catastrophic overheat when a coolant hose ruptured. Apparently the cause of the hose rupturing was not related to a manufactures defect and the customer had to foot the bill out of pocket, over 30k to replace this engine on a new car!
Today we tear down this engine all the way to see just how bad it was. Could it have been fixed? Was an engine replacement necessary? This teardown easily answers those questions as well as showcases some pretty neat technology on this still current engine.
Why am I doing this? My name is Eric and I own and run a full service auto salvage business called Importapart. Part of our model includes dismantling and tearing down blown up, bad, and core engines to salvage the good usable components and recycling the rest. We do not rebuild engines, merely supply parts to those who do!
I really hope you enjoyed this teardown. As always I love all of the comments, feedback and even the criticism. Catch you on the next one!

"They don't want you to work on it"
You just explained the modern automotive industry.....
I can't wait until the cam in valve cover becomes widespread. Then no one will want to work on it.
so true. its buy a car drive it for 5 years then dispose and buy a new one.
Lucky those bolts aren't alluminium 😂
the modern "anything" industry.
this is true on motorcycles aswell. when my 2018 yamaha scooter needed a new top end it was nearly impossible to work on it and they had a spacial tool required for basically every bolt.

Proceeds to work perfectly.
Eric's a humble man 😂
@@samholdsworth420 - Yea.....i always set the bar low for myself. I would've said the same thing had it been me in that situation.
Eric pulls the “milkshake pump” gets pristine coolant.

Before giving one's best effort, it is helpful to set low expectations for the outcome of that effort, as they can be exceeded and it isn't a crippling disappointment if they aren't. This sums up my approach to life. Try hard, expect little and be grateful when things occasionally do go my way. Who knew Eric is such a philosophical life coach? 😄
Yes
Eric, I just saw a video on Rainman Ray's Repairs that discussed your collaboration with Ray in saving the van for the afflicted family. Hats off to you, brother! God bless you and Ray!! This is why I watch you guys. I am very proud of you both!

Just once I want to hear a Wilhelm scream when you throw a perfectly reusable chain guide.
Or the water pump & electronic thermostat 😆
I barely trust a *new* German chain guide, no way I’d reuse one.
And get him sued by Disney?
Should mount a bunch of those in an epoxy table
Those audi guides are so expensive, and chains, and many of them there is no aftermarket. Kind of makes buying any rear timing chain engine car, not a real prospect.
"Many feeler gauges of thickness". Yes Eric, Yes it is.
Americans will use any measuring system rather than the metric system ;)
I often think about the irony of this. The engineers spend years developing this exotic technology, the advertisers flaunt it, the dealers brag, and the owners are all proud to own such machinery. And then in a few years it goes to the scrap yard.
Tell my 2015 VW 1.8 turbo that. At 55k miles and it runs perfect.
They should save everyone the trouble and just ship them straight to the scrap yards! 😂
I say the same thing when I'm in the yard looking for parts. No matter what you drive, except exotics, that's where they all go. I still have a picture of a Rolls in the yard. it got picked clean in 3 days.
I don't think we'll ever see better built or longer lasting luxury cars than the Lexus LS400 and the Mercedes W124. The sort of customers that buy luxury cars nowadays do not care about longevity outside of the warranty period. They can afford to replace them every few years, and it's clear the design priorities have shifted to match customer preference.
Over a decade later and the 3.2 vr6 in my audi is still running and still wanted.
Saying they end up in a scrap yard is delusional
I've watched you for a long time and my wife will generally watch. I have to add a little more narrative for her to understand what you are doing. On occasion, I get exhausted watching you because I think, 'Thank the Lord, that is not me trying to work on one of my engines'...which I used to do...before I was 89 with two new knees. I pretend that my engine work went as smoothly as yours while knowing it never did. Right now, my 1996 Buick Roadmaster Estate Wagon (5.7 liter) needs a power steering hose. I have someone I will trust to do that. Thanks for the good cheer and hard work that I do not have to do.
My wifes 7 year old land rover hit a small rock and it caused a coolant leak. She figured she would keep on driving until I had a chance to look at it. People make bad choices. Expensive repair.
My wife will pull over and call me after a scary pot hole even when the car is obviously fine, so it can go both ways lol
Your bad choice was getting married? I hear ya
@yeahitskimmel sounds like my wife I have mud tires so they are ruff when it's cold out every winter she freaks out and calls me because it has a bad vibration lol
Dude you just reminded me to check my coolant thank you oml
@@RadDadisRadHe's M.G.T.O.W, Now 🌞🤠😮🤓
That 100% deserves a rebuild.
yup, deck the heads and block, crack test, if ok, new bearings, new rings, pistons looks reasonable, but likely replace as it clearly overheated, re-assemble and away you go...it looks like in reasonably good condition...
Can't rebuilt German engines. Every time I've seen someone try ,they never lasted. Plus they don't have any tolerance for machine work to be done on them
@@peterpeter5666 an almost new Audi engine, overheated on both cilinderbanks, plastic waterpumpimpeller. Variable camshaft timing, electronic thermosthat, built-in failure points in my opinion. No good sign of engineering and building quality here. Throw-away engines, that's what they are
As an Audi tech who has worked on these engines, there's pretty much a 0% chance of rebuilding these without the factory tools required to do so. I know there's guys out there that would say "yeah, you could just rig something up to make it work" but you really can't on this engine. The timing alone requires cam locks, crank lock and locking pins for the zero lash pulley that you see removed at 14:15.
@@jonmallard2176 MY EXPERIENCE WITH German cars as a tech for 40 years is , what ever you do to these engines, after they fail is a bandage and they will eventually fail again in a short time. Pretty sure as a tech at audi when every you had engine issues , 99% of the time it was a new engine in a crate.
Former Audi tech here... These are actually a whole lot easier to tear down than the older engines. The stand and adapters from Audi for the V6 was like 20k. The table the pull them out was another 10k.
Can you do full timing and major repairs with the engine still in the car?
very curious how the dual cam lobes are operated at the different rpm ranges.
@@jacobpickering8586 Same. I suspect the lobes move from left to right on the shaft. The solenoid engages ramps on the lobes so when they turn the "lobes" follow. You can just barely see some splines under the cam lobes when he does a close up on the shafts.
I'm not even a car guy and watched the whole video, and coming from someone who can just about tell the difference between a steering wheel and a back bumper, i don't know who you guys get your head around this stuff, gave me the shivers just watching! And 30k, for an engine. Incredible.
As a German, I don’t understand at all people buying VW/Audi stuff.
fun to lease, do not ltrust lol
The EA839 is a great engine. This engine likely blew up due to user error hence why the warranty was voided. Can’t fix stupid.
My GTI is a blast.
What brands do you like as a German?
Which is why at least in America they have struggled compared to nearly all other legacy automakers whether economy or luxury..
Personally wouldn't mind owning a manual R8 and VW XL1 but in general most of their products fail to interest me.
I actually got Audi commercial breaks in this video. 😂
Take that as a warning!
@@tomrogers9467 yeah.
LOL. No way!
Checked my book, I've done 6 of these engines which had multiple head gasket breaches as you found, every single one was warrantied as soon as we found the head gasket issue, meaning new replacements were fitted (£32K/job). Each removed one was a complete teardown, wash and rebuild with head and block skims AND new shells, timing gear all round. Total cost £4Kper engine, majority being labour.
Madness 🙄 a, they don't have the ability or b, the Labour costs per hour are Laughable, c, I would demand a new Car with the new Engine if it was just months old like his Engine looked !!!
Simple repair for a real Mechanic - By the way that residue coolant in the oil would mostly evaporate off with a 10 mile drive, So the Engine did not need a full strip down if the Block was Flat, Just a couple of oil changes.
“… with a dose of M.M.O. to help clean things out?”
@@dennisyoung4631 snake oil
Were those head gaskets faulty or did something else go wrong and the person kept driving anyhow - CAUSING the more serious engine damage? People are dumb and they'll take a chance rather than take a walk.
It had a water pipe burst loosing its coolant..causing head gasket failure
I rented this exact car a few weeks ago. I got my first speeding ticket in 25 years. Never driven a car that goes from 80 to a 110 like this one did. This engine has some serious power in that little car.
S5 is no joke.
After seeing this teardown. It makes me appreciate my honda K20 i adjusted the valves on today. 328,000 miles and it purrs. Had a leaky valve cover gasket so did some adjustments while i had it off
Same for my Camry 4cyl 5SFE, 355k miles and only time the engine was touched is a valve cover gasket
Honda K-series engines are amazing. I plan to get at least 300K on my K24.
my 2003 bonneville SSEi supercharged L67, 21 years old and just runs incredibly well. it only has 125K on it but still it runs like brand new. tons of torque (pulley swap), it's less then halfway through it's lifespan. 3800's, probably GM's best made V6..... ever.
SR20 life here, 280k still runs like a champ!
how much were the valves off of spec?
Omg! Yes!!!! I actually have this engine in my SQ5 and cannot wait to watch this video!
Well, 2 minutes in and no, no one has tuned them to 450/600 with just a simple flash tune…
Nope no one ever
Have a SQ5, should I be nervous now?
@@rleger123have you turned yours up?
I think a flash tune might've been the reason for the warranty denial. Also the case of failure if it was a particularly aggressive tune, putting a ton more boost without the proper supporting mods (upgraded intercooler, radiator etc.) will mean a lot more heat, so heads start warping and more boost will 'help' compression go past the head gaskets.
@@raoulrr
Don't forget the "hot V"....all that heat going out into the V...
oh wait.....
that's the 'side" of the head/block that got really really hot
right where the unitary exhaust goes out to the turbo?
Do an oil change 😂😂
I worked on a vw 10+ years ago and told myself ill never buy anything vw again and dont regret it to this day
Great engineering is accomplishing complicated things done in simple ways. However, VW loves to do simple things in complicated ways. For absolutely no reason. They even do stupid things like make the flywheel bolt holes all the way through the crank shaft so if you don't make sure to seal the bolts completely all the way around with thread locker your actual crank shaft will leak oil and fling it all over your new clutch so that gets destroyed for no reason as well.
The right way, the wrong way, and the German way.
They're fine if you follow Elsawin, keep the oil changes. Pretty basic really. Worked on multiple engines over a period of 15 years. My wifes Octavia has 160K miles, still runs like new due to the fact that I have kept the maintenance up. Only thing replaced was battery and water pump.
My daily is a '68 beetle. Awesome car, super easy and cheap to work on. Pretty much have done everything which isn't saying much, there really isn't anything to do. Can say I can pull the engine and put it back in, in less time than it takes to change and bleed the brake master cylinder. Geez what a PITA. I know you weren't going all the way back to the date with your comment, but if you want a solid, easy car to maintain, those fit the bill.
@@user-rv5tw2nw7f old German tech is amazing its all the newer things that went down a steep hill. I recently had a 1992 mercedes 420 and it was a tank with 180k miles all original and running like new
It just kills me how people buy a brand new car, rag on it, tune it, and beat on it some more, (and its still in the break in period) and then imagine their surprise when it blows up.
My first brand new car: 2023 Ford F150 5.0, for the first 2,000 miles, I babied it. I'm at 9,000 miles, 1 oil change in, about to do a 2nd oil change, still haven't tuned it or done any engine mods... Why? Because I like my warranty.
car could have been stolen then thrashed? Car thieves tend not to care if a coolant hose blows..
@@wilson2455 The insurance company would have totaled it, paid out to the owner and the car would be in COPART lot..
Yep. I have a kia cerato GT. Lotta guys do a flash tune, turn up the boost etc. As soon as they get the car new. Like you i like my 7 year new car warranty..
All of my new Ford trucks I have babies until 30k then all the mods come out and no problems.
police report would have been generated
The machine work on that engine is state of the art. Just beautiful to look at. Thanks Eric.
And totally over engineered for what it is.
For what it is? I mean, it’s compact, and the casting is obviously designed to be very strong but as lightweight as possible. I was prepared for yet another truly over-engineered positively infuriating German engine, and I was pleasantly surprised to be wrong. In my opinion, this might be one of the least “over engineered” engines I’ve seen in the modern era. It’s refreshingly free of gratuitous parts, moving and otherwise, and it’s refreshingly free of plastic and other cut-cost parts. Everything you see makes sense, like it was done for good reason. There’s a lack of unnecessary timing chains, idlers, tensioners, or guides, and the water pump isn’t buried under there. The cam chains counterrotate using the geared balance shaft to drive them reducing chain length and weight. The hot Vee is all the better to feed the turbos. The timing chains being on the “wrong” end makes it more compact. The unique camshaft/valve cover assembly is also simple, compact, and leads to shorter engine height. In addition to timing phasers on the intake and exhaust sprockets, the assembly also incorporates a simple mechanism equivalent to Honda V-TEC (specifically, V-TEC’s selectable cam profiles) without stepping on Honda’s toes. It’s no Ford 300, but those days are over and they aren’t coming back. For its feature set, I’ll dare say it, this Audi is almost minimalist.
@@johnarnold893 _" totally over engineered for what it is."_
And how would you have achieved the same power, torque, weight and fuel economy/emissions with less engineering?
These things are over engineered hence why they can take so much horsepower with relatively little work.
@@ferrumignis With a V8 LS, pushrods and compactness at fraction of the cost - $10k. LS may be a little less fuel efficient, but the difference in cost makes up for that. Audi engines are ridiculous complex and so expensive at over $30k for a V6 and $40K for a V8. Further, LS engines do not require replacement of cheap valve guides at 60 to 80 k miles.
That S5 thermostat was worth about $550 & $480 to install. Should have kept it ! Lol
It's been bathed in super hot coolant or steam........
not reliable any more??
Eric won't even consider selling it.....
I saw something get thrown into the waste bin, but was it the thermostat from this engine.....
@@wino99999
Yes.
The chances of it being overheated were too great to allow Eric to ethically sell it...
and anyway he always throws thermostats away....
I'm not sure how these are designed, but an overheat could easily have subtly ruined the thermostat. Traditional 'wax pellet' thermostats use a wax that only significantly expands when it reaches a critical temperature. The wax continues to expand if it gets hotter. The operating spring compensates for some expansion, but when it bottoms out some wax will escape. The missing wax results in a thermostat that still starts opening at the target temperature, but doesn't fully open until a much higher temperature.
This effect is amplified in an ECU controlled thermostat. Those use a heating element in the wax to allow the ECU adjust the operating temperature while remaining fail-safe as a traditional thermostat if something goes wrong. During an overheat ECU will operate the embedded heater at full force in an attempt to cool the engine, possibly ruining the thermostat in an attempt to save the engine.
Older ECUs didn't log this as a failure event. Perhaps this Audi does, and also logged how many times it warned the driver that something was wrong.
I will not modify a new 3000$ engine. Why young people will eagerly modify 30,000$ engine speaks to apathy and stupidity.
Eric this is the first time I've watched your video. I watch Ray,s Repairs and I saw how fantastic it is that you and Ray are helping out the family with the Chrysler van blown engine. It's really nice of you both to lend a helping hand to a family that is going through such a hard time. Thank you for being so kind with your time and donating a engine to the cause. Bless you and Ray
Makes me wonder if the dealer didn't pull the computer's logs and see a flash tune. Instant warranty denial.
Easy and likely. Better to under run an engine than blow it. They ain't cheap!
Only at first - the burden is still on Audi at that point to prove that the tune caused the damage or failure. A smart customer that now has breakdown evidence could go back and fight this one. This is a clear fault failure there was no damage or evidence to show that any modifications could have caused this damage.
@@dontimlin4506 I wish thats how it was but its not unfortunately. Most euro brands void the warranty the moment you scan a car that has a tune. As a former BMW tech at a dealer, the moment I hooked a car up with a tune, that was it, the files are remotely uploaded to BMWs server and a record is kept. Once you tune a BMW its recorded forever in the ECMs programming data
That's what happened!
Standard protocol is to scan vehicle to check for aftermarket tune. If the car isn't scanned warranty claim is automatically denied and dealership has to foot the bill.
I work with these just about every day. Oil filter housings, PCV's, water pumps and thermostats, that valve that brings vacuum to the water pump, oil strainers, turbos, timing covers... I uhhh... Yeet. But thanks for the teardown as always! To anybody that has this engine, the code is CWGD, 8.0 qts. of 0W-20 (T40718 dipstick tool 76 0 14 or 16), 12-point spark plugs that are a 14mm, and these engines are in way too many of our cars. Water pumps are a pain because #serviceposition.

Perfect time to watch a new Taredown 😎.
Perfrct time, perfect engine
In the event you don't know the correct spelling is "teardown" I just wanted to leave this comment
I recently tore down a 430 MEL (mercury Edsel Lincoln) 430 engine out of my 1961 Lincoln. I bought it out of upstate NY and it had not run since 1977. Additionally, the vapor screen for the PCV valve was totally blocked, likely never cleaned in its 56000 miles. It was disgustingly filthy inside. Also, the evolution of the auto engine from 1961 (designed in mid 1950s) to this Audi engine is absolutely unbelievable. Thanks for posting.
Had a 70's Datsun 2 ltr 4 cyl truck. Blew a heater hose on the way to work and continued my trip (3 miles). I watch heat gauge and it stayed in the safe zone. Problem is gauge sender is in the block and the head didn't have coolant. Relatively easy to pull head, get it planed and re-installed but a lesson that cost. Thanks for sharing video.
Worth mentioning Eric that the balance shaft is spun by that idler gear above the back of the crankshaft, which clearly has a built in counter weight, to oppose the counter weight at the front of the engine.
43:40 I freaking SNORTED. Loudly. Then rewound, to hear it again. Love your channel bro.
I expect boring jokes from the machinists, not the mechanics
Funny Eric that you chose this engine this weekend as it seems it was nearly defective out of the box, just like the new GM fuel pump my coworker bought for his 07 Sierra 1500, which I spent my Saturday helping him install. His old fuel pump still worked but there was this strange wetness and fuel smell from the top of the old pump😉. After we dealt with all rusty straps, removed the fuel line from the old pump and got it all back in the truck we found that when you cycle the key the new pump would only pump for about two seconds and no fuel was getting to the engine.
We tried plugging in the old pump (which the truck drove in with, and was now oddly missing its fuel outlet fitting) to see if it powered up any differently, it didn’t. We looked for bent pins on connectors, plugged evap lines, etc, before finally dropping the tank again and comparing the pumps, we couldn’t spot any differences between them. It wasn’t until we tried powering up both pumps, while only partially submerged in gas, that we found the problem. The old pump would push fuel out of the broken(and slightly brown) outlet, the new pump was just splashing fuel around inside the lower housing that surrounds the actual pump. This pointed us towards the actual problem with the new GM pump. The actual fuel pump had a broken outlet where it connected to the rest of the plastic pump housing, and was just pumping fuel back into the tank. After a few deals were made over the phone between my coworker and the GM dealer we installed the old pump in the new housing and the truck ran fine.
Fascinating tear down, more than impressed with your knowledge and ability to pull these mills apart.
Great respect and so damned sad for the owner of the car and the expense they must have had. Well done and keep up the amazing work!
I really thought you were gonna leave those guides alone lol
Love to see, machine shop diagnosis of warpage, on heads, block, valve covers and cylinder bore.

@@I_Do_Cars big ends. proly need a diff spreader, ish..
MSRP was $56,395 to $64,495 for the coupe and $64,495 to $72,595 for the convertible. A bill for half the price of the car seems like a replace-the-car scenario to me.
That works if you don't have a note on it.
Close call. Buy a new one or lightly used one and part out the old one. Hopefully a specialist salvage yard would pay decent money for it.
“the car still had temp tags on it”
I'm laughing because all the EV haters keep going on about the price of a replacement high voltage battery writing off the car.
ICE engines are just as bad.
I would never understand why anyone would do that. At that point I'd just go ls1 swap for a small fraction of the cost
I had an 01 2.8ltr wagon that had 295K miles. I took it in for all oil changes and maintenance to the dealer I bought it from. They had these weird locking coolant hoses and at the last visit they didn't make sure to push the lower hose all the way on the radiator. After it stalled just a couple of blocks away, I had it towed back to the dealer. They refunded 200 of my 2500 dollar bill and told me I would have to sue to get the rest back because the car had so many miles that it wouldn't have run much longer anyway. The scrapper gave me another 250 for the car and Audi has lost a customer for life. These engines do not survive an overheat.
You SHOULD have sued them. Always call their bluff with three estimates higher than theirs plus legal expenses. They would have lost and you would have gotten paid.
Sounds like you blamed the manufacturer for the dealers mistake....
I would have sued. Why else would someone sink $2500 but to enjoy it another 50K miles.
Rainman Ray sent me here. Subscribed. Good thing to day is a Rainy Day, 'cause I'll be binge watching.

The more I watch modern engines being torn down, the more I love my Buick 3800.
ok external pil pump boy
And then we drive a modern day car and hate the Buick 😂😂😂
I got the Oldsmobile 3.5, most powerful engine used in a W chassis. Very good engine.
man, I had the 3800 in my first car, a 06 regal. the fucking car fell apart around me, but I was able to drive it to the junkyard under its own power and even the day she went had just as powerful of a motor as ever. I had just hydroplaned into the wall on the highway and fucked the front end, so it was toast even though I still drive it with no front bumper and a bent bumper bar and missing a headlight for 4 or 5 months after that. lol. good times being 16 years old. but that 3800 will always hold a special place in my heart
Very very beautifully built engine. I enjoyed every second!
The castings on that engine are beautiful. Nice quality aluminum.
How about a collaboration with @VAG Technic? Just box up the parts and send it to them for a rebuild. It seems they are always tearing-down engines, and this one would a good replacement for anyone that has blown up a 2017+ 3.0 TFSI.
the days of telling your 16 year old son go fix his car is over
My 16 year old son's first car would never have been an Audi. It would have been with money he earned.
Only if you buy modern. My friend Sam and I can swap out an LS motor from a silverado in 2 hours flat if we wanted. Weve done an LS swap with 4 guys in about 40 minutes. Modern engines are overly complex with BS valve timing. Its all a gimmick.
You don't have to buy your 16 year old son a brand new Audi S5 you know.
If you look at the used car market, prices or skyrocketing. I know this has a lot of factors including the economy. Yet, you're going to start seeing more more people keeping older vehicles going. I have a 2005 Yukon that I just put a 60,000 mi 5'3 in. I'm slowly repairing everything on it because they just don't make them like that anymore. I'm sure every generation says this though so I guess we'll see.

"Lemon Jam" is my phrase of the week. Thanks Eric!
Eric, you and Ray are both class acts.
I suspect the main bearing caps were installed cryogenically. Freeze the caps to a shrinking point, install. At room temperature, they'll fit snuggly.
Called an 'interference fit.' At room temperature the bearing caps are actually larger than the block. Also used to install bearings on shafts so they stay tight.
So I have a 2018 S5 coupe using this same engine; the only major difference is the smaller needle bearings on the roller rockers pre-2020 which have caused some failures. From what I can tell, it's not as widespread as the forums would have you believe and even those engines are pretty solid. The Audi Valvelift System is really cool and allows the engine in low demand situations to run as a Miller cycle engine, resulting in shockingly good fuel economy, and it does so in a way that's quite a lot simpler than VANOS. Seeing this video really made me appreciate just how elegant the system is. Assuming I can keep my right foot light, which is a big ask on open stretches of lonely highway, I can get upwards of 33MPG highway with this thing. My record is 34MPG but that was in a construction zone heavy area so I basically had to hyper mile it anyway.
I have 86K miles on mine so far; let's discuss the failures. One slightly noisy strut, one oil cooler with a slow leak and some speaker grill rattles were fixed under the CPO warranty. An engine mount, driver's window regulator, one wheel bearing and some misc suspension bushings were replaced under the extended service contract at 84K. It's no 1999 Camry, but for a fun car, it hasn't been too hard to keep. (The 1999 Camry is indeed what I drive when this thing is in the shop. It's as reliable as a Panasonic AM radio but about as entertaining.)
These engines call for a specific oil spec, VW 508 00. Use ONLY oils meeting this spec or you'll be very, very sad when the bill comes. More on that here: ato24.de/en/blog/comparison-0w-20-engine-oils/
The coating on the bearings is likely to prevent excessive wear with the start-stop system. I use it only in moderate city traffic and turn it off in stop and go jams. It dramatically improves city economy when used in moderate city traffic where stops are due to lights (about 4MPG!) but it's annoying and will probably cause excessive wear in traffic jam situations where you only stay stationary for a few seconds at a time. The fuel savings in frequent low speed stop and go scenarios appear to be extremely small; I usually see about a 1mpg improvement in my morning North Dallas Tollway commute unless there's a big wreck, and I'm stopped longer. (of course, at that point, you can probably just put it in park!)
As for the coolant loss, Audis will make a hell of a ruckus and practically take over the instrument panel with warnings should a critical failure occur that requires the driver to stop. Even when a relatively minor thing happens such as a TPMS warning, it can be a bit of a diva with a warning that briefly consumes 1/3 of the virtual cockpit display and a loud tone. You'd have to be deaf and blind not to get the warning.
The comment about overtaking the gauge cluster for a simple warning is how all German companies do it. I work for a VW dealer in StL now and was working for a BMW dealer in the area for the last 3 years. I currently have a 2018 S4 running 034 stage 2 E85 tune. If something is not right, the Germans certainly tell you about it.
I’ve been having the VW 508.00 debate for a while about my 2018 S4. I’ve decided to try 504/507 0w-30 this summer for better protection in the heat. I’m doing 5k mileage intervals.
I bought the oil change kit for the RS equivalent, with the branded oil.
I always turn off my start stop. I'm retired so I don't care about gas mileage. I heard the main reason for that system is for emissions not so much fuel savings. No mater what I'm told, stopping and starting an engine multiple time per trip compared to once can't be good for the vehicle.
Eric, that was therapeutic. Thanks!
Love the stress test😂
Eric... Eric... how many times have you drained an engine because you didn't want to turn it upside down with all that in it and make a mess. And here you are proving yourself 100% correct. 😂😂
Thanks for the video, this was a fascinating look into modern engine design. Even the Main caps were lightened. A lot of people will probably have bad things to say about modern VWAG cars and engines but the quality of the parts in that engine were really apparent. Unfortunately, you probably can't see any of it when it's in the car as it's buried under 8 miles of hoses and wiring.
If I had to guess, they probably modded the engine in some way. VAG are very much sticklers about modding and warranties. You mod it, you void it. Could also be what caused the gasket failure.
Any dealer would deny if a tune shows up.
@@Confirm_selection I work for a Kia dealer. After the bad publicity from recent engine problems, Kia replaced an engine that was tuned, simply to avoid the arguments. We felt it was just encouraging bad behavior, but it wasn't our decision. We got the warranty income, of course.
Lmao. Kia is a far cry from Audi my friend. @@greeneyesms
@@greeneyesms The 2.4L n/a engines are the crappy ones. No chance someone tried tuning one of those--
A lot of professional engine stands use engine mount location to attach the engine to the stand. So the engine sits at 90 degrees to the regular mounting location at the back.
THANKS FOR THE CONTENT> GOOD JOB
The non-magnetic bolts are made from Audiminium
Aka rebranded Chinesium
At $43 a bolt!
Wow, that's a very impressive engine! I've heard they are reliable, but seeing the design, I can understand a bit better why they are good.
Obviously the owner bought a bad tune. And of course the tuner will take no responsibility for blowing the engine.
Thanks for the break down. I learned a few things .
I bought the Audi A5 40 tdi quattro in 2021. My first and only brand new car. I intend to keep it for a long time. Just over 18.5k miles so far. No issues. Hope it stays that way.
Those solenoids are for shiftable cams to use the different profiles. GM has been doing the same on their 2.0L "LSY" and the 2.7L "Turbomax" engines from 2019+ on both cams. There's a high lift, low lift, and no lift (AFM) profiles.
I wonder if in time and high miles those sliding splines will start wearing out and cam lobes start binding when trying to shift. I guess time will tell.
Also yes those 'cam carrier' gaskets do leak, the 2.0L engine specifically are notorious for it and require retiming the engine but the chain and cams are locked during the repair.
Audi's used this system (they call it AVS) on a few engines now, going back over a decade, and I haven't heard of it going bad. On my VW GTI's gen 3 EA888 specifically, the main issue is the VVT solenoids (not the lift ones) going bad from being run low on oil consistently
Should have a fail-safe, likely low lift, but today who knows, probably fails into afm!
I knew I was outgunned when the service writer at the Porsche/Audi dealership made me feel inadequate for not paying $1,100 for an oil change! Thank you for listening. I feel better now. R
Learn how to do a service yourself. A complete service with oil + oil filter, air filter, fuel filter and cabin filter will cost about 450 to 500 on materials. Or find a good mechanic that will do it for a reasonable price. Even the reset after the service can be done without diagnostic tools moost time. These German cars (BMW, Audi, Porsche, Marceders) are critical for service because they have extreme tight tolerances and high power output to displacement. where you can be lazy with air, fuel and cabin filters your oil service should not be neglected, better to soon than to late. Also the engine must be used calmly until it is at temperature (90deg celsius) before you squeeze out all the power. If you do that your engine will not end up on this channel.
If you signed the estimate with "R" I'd overcharge you as well 😆
jeez what vehicle?
@@azi6477$500 worth of filters? Holy cow!
Just had a oil changed on my VW at Vavoline. Psst. the 1.8 TSI engine is the same engine as in an Audi TT. Cost $125 which I thought was high. Only thing I get VW to service is Trans fluid changes. Last one I had done cost about $240. Valvoline don't drop the drain plug to drain the oil, , they suck the oil out of the dip stick tube. At least they don't forget to tighten the drain plug that way. Cheers.
I simply can not live without a video of yours in the weekend. I truly love your videos and have learned absolutely so much when it comes to engines. However, can you do more diesels? More Duramaxes, Cummins or Powerstrokes, and you're also for getting the old 6.2Land 6.5L Detroit Diesels.
First one but not the last. Unfortunately an expensive mistake. A bonanza in parts sales for u. I am happy for u. I have to admire your work ethic. Keep uploading thanks.
German cars and preventative maintenance go in hand.
another good vid pal
As someone who drives a '96 Tacoma 2.4L 2wd I'm always looking for parts due to extreme rust. Though I love the fact that my grandpa, who had the truck before me, installed a supercharger kit on it. It is so much fun as I'm still continuing to add different things to it. I would love to see either of the two four cylinder (2.4 2rz-fe or 2.7 3rz-fe) 1st gen Tacoma engines torn down.
They're all still running
I just watched RRR video, You are a good man Eric.
I have a loaded 2024 S5 Sportback, except the track steering option, and the car is pretty fun to drive. You can tell the engine has more potential and I know from the Audi forums that people like to mod them, mine is stock. My guess, the owner modified the engine, possibly chipped it or mucked with the ECU/ECM and drove the crap out of it. Very interesting to see the variable cam design, it helps me understand how there are drastic performance changes, depending on what performance mode you select.
Honestly the cams/valve cover being an assembly is pretty neat.
Agreed.
And then they put the timing system in the rear of the engine…
Germans.
Especially no bearings - just using the cap and valve cover housings as the bearing material.
@@salninethousand2496 Bare aluminum used as cam bearings has been common for decades. It is reliable and long lasting as long as there is at least some oil flow and the oil is well filtered. Anything the oil will chew up the aluminum casting on the way through.
The difference here is that the larger casting is used to resist the primary forces rather than cam caps. That might result in less flex, which could improve longevity, or a lighter assembly.
There isn't any argument about wear on the more expensive larger casting vs cam caps. Cam carriers are line bored. Wearing out the bearing surface on either side means that the whole assembly is trash.
@@1djbeckerBut then you can replace just the carrier instead of the whole head.
@@802Garage There are plenty of engines where the cam carrier is not part of the head casting. The primary reason is usually machining geometry, but it allows using an alloy with improved wear resistance.
Eric: "You guys thought I was gonna throw that?"
Me: "Yes, 100%, no questions asked, definitely, absolutely."
Eric.. love the teardown videos. Wondered what you use to clean the oil and other goop from your floor after the camera work is done?
Just bought a souvenir from this one! Something to remind me to take care of my 2024 EA839
I saw a comment here that "when water turns to steam, it is only 212 deg."
So, so wrong. Look up "steam pressure vs temperature" chart.
Steam can be 1000 deg, F Or C, or more...any temp, until it becomes plasma.
I heard that in old power plants, a rag on a stick was sometimes used to find very small leaks, and that a burning rag could result. I don't know if that is true, but the temperatures were certainly high enough, and the escaping steam would only condense to visible vapor some distance from a small leak.
You cannot see steam, only the tiny drops of condensate that form after cooling.
The audi probably has 1 atm. or more of cooling system pressure, raising the boiling temp considerably, which is the whole reason for going through the trouble of having a pressurized cooling system.
The higher temp allows for more heat rejection from a given size radiator, airspeed, & air temp.
The Navy would use a broom to find steam leaks.
They run high temps mainly for emission purposes while kipping coolant from boiling via pressurized system ,coolant antifreeze boils above 225 at sea level giving out steam as temps goes above that .Vaporized liquid steals heat from its source caring it away to a new destination .
I’m a tech at Audi and we recently had an S5 in the shop (maybe like three months ago) anyways it had 1800 miles on it and had a bad knock. Low compression in like 4 and 5 or something. Metal in the oil filter. Anyways it was tuned so warranty was denied. I’m kind of wondering if this is the engine. Came from Raleigh, NC.
That's got to be one of the most beautiful timing systems I've ever seen.
Amazing tear down. Would love to know all the circumstances behind this engines life.
You mentioned the sealants. I think most engines with no age or run time would seem to have amazing sealants. Very little age, heat stress and time to harden and deteriorate.
Death by caramel milk shake!! Thanks for your time, love the tear downs.
Moral of the story. Dont mess with the tune, or boost if you cant afford to replace a 30k dollar engine.
Did he say the failure was a result of modification?
@@guthrie_1 as a euro tech, warranty kicked it for one of two reasons, one, the car overheated and the customer (ignoring warning lights) drove until the car shut off. or option two, it had an aftermarket tune on the car, either situation would have resulted in audi denying the warranty. saw it happen at bmw with a m340i with a stage one flash tune, car lost compression and bmw kicked the claim, customer paid out of pocket for repairs.
@@guthrie_1 in deed tuned turbo-pressure and messing with the ecu also was the first possible reason, which came to my mind seeing the damage and getting the fact, that warranty was denied.
@@guthrie_1 He said a coolant line burst that was unrelated to a manufacturing defect, so I'm going to go with "yes" unless a squirrel ate through it or something
@@paulbruneau7379 yeah I’m not aware of any bolt on modification that causes coolant lines to burst.
speaking on mounting the engine to a stand, all cwgd engines taken out are normally held on with chains on an engine hoist. That is the purpose of the black hook receivers on the heads, and is what is used at my dealership. Thank you for the great content and tearing down of this audi engine, I normally see these having sparkles in the oil as little as 5k miles so sooner or later I hoped to see you tear one down.
You don't really want to be half pulling apart an engine on a hoist, though. That's asking for trouble.
Terribly sorry to hear you have to fix things like that.
That is such a cool design where it has siliniods that slide a cam profile into place. Changing the performance
Love this video. I been planning to get SQ5 for few years already will probably get it later when I get more money. I think people are right this car was tuned and abused and it caused warranty claim denial. I think best idea for those who want the car faster and under warranty is to get lightweight wheels that are much lighter than the OEM ones, they have 18x9 Enkei available for Sq5 for example that weigh only 19 lbs or 18 lbs per wheel instead of like 28 lbs for OEM wheel and the car will be about .4 seconds faster from 0-60 without voiding your powertrain warranty....
Impressive rocker roller bearings. Looks like they'd survive a long time, but the best is still a bushing. Tell GM and Ram to up their game.
As a GM engineer, this reminds me of the era when head gaskets were common failure points. GM spent millions trying to fix this with O-rings, glue, compressed metal, exotic materials, and other whatnots. When aluminum heads were mated to iron blocks, the problems got worse. I had a 240Z/280Z car with iron heads, iron block, where I got 230,000 miles out of a head gasket, before repair was needed. Eventually scrapped the car with about 666,000 miles on the block. Purchase cost of the car was 2400$usd. Saved me millions of dollars as compared to any Euro brand. Only GMC engines are as good.
240Z/280Z did NOT have an iron head! Typical GM engineer?????
I have a 2021 Porsche Macan GTS with a some kind of Audi turbo V6. A couple of months ago I picked a rock that smacked the radiator and broke a coolant line. As soon as I noticed warnings and fume coming out from the hood I stopped and had the car towed in. Lucky nothing bad happened, the radiator was replaced and all is good. And it wasn't covered under warranty just like this guy but my comprehensive part less deductible covered the repair. In these modern high performance cars you have to take fluid leaks seriously.
