Disaster Engine! Audi 3.2L V6
HTML-код
- Опубликовано: 26 июл 2024
- Here's a look inside Audi's infamous 3.2L V6 and how it works!
The engine in the video is from a 2012 Audi Q5. This is a 90 degree V6 engine that features direct injection, which often causes issues with carbon buildup. However, this engine suffered major catastrophic damage to the connecting rod, engine block, upper oil pan and PCV system. This was likely due to oil starvation.
There are a few flaws with this engine design that make it far from robust. The oil system allows unfiltered oil to travel to the top of the engine block, through many oil galleries before reach the filter and then cooler. The direct injection system is known to cause extreme carbon buildup, often requiring an induction cleaning service dismantling the top of the engine. There is a driveshaft that powers the oil pump, and the timing components are on the back of the engine, requiring transmission removal to service. There is an abundant use of plastics across the engine, including numerous cooling components that can cause leaks.

Plastic cooling components.. too many chains all on the backside of the engine.. no port fuel injection to clean air inlets.. no dipstick (not that Audi owners care much about checking oil).. what could go wrong?
Plastic cooling components are a terrible idea given that they use nylon which is known to degrade with water, and with hot water the degradation is greatly accelerated. As someone who has an A4 with a previous generation 3.2 FSI (no variable valve lift system), I can confirm that the front coolant pipe is a terrible design and is a pain to replace. At least the chain system is known to be reliable and I haven't had any major engine issues even though I purchased the vehicle used with 150,000 miles. When I changed the valve cover gaskets, the valvetrain looked very clean, although this may be attributable to the fact that these earlier engines have dipsticks and that the previous owners had the car serviced on time.
Have you ever talked to one of the engineers?
@@michaelliles2157 engineers aren't making the ultimate decision. Any engineer understands that metal does a better job at themal cycling than any composite or plastic. I'm a mechanical engineer myself.
The requirements flown down from corporate that engineers have to abide by are driven by cost and not ultimate reliability. I'd be willing to bet most engineers at these companies are car people themselves and understand a lot of modern auto design is profit-driven.
No engineer purposely builds plastic cam chain guides out of reliability. There more to it than that.
Well said lol. That's why a lot usually goes wrong with these engines
Your typical VAG junk.
I used to work at a VW/Audi dealership. You are 100% correct that the engine is designed to come out often for warranty work. The direction is opposite though - they drop it out from the bottom with the transmission (often) still attached. A good tech can do it surprisingly quickly. As a consumer when you hear the engine has to come out the dollar signs start flashing from all that labour but it's nowhere near as bad as you'd expect. Not ideal, but you don't have to 2nd mortgage the house to have it done.
Rant - my beef with all these luxury German vehicles is their ridiculous oil drain intervals. It's one thing to designate 15,000 or 20,000km oil changes but no one checks their oil level regularly or at all. Next thing you know the oil gets burned off and the level drops and things start wearing fast and eventually it gets starved of oil. If these folks would just check their oil level and top off when necessary between oil changes most issues would be avoided. More ridiculous these days as on a lot of these vehicles it's just a menu item on your screen, you don't even need to pop the hood to check it. Rant over.
"it's not that hard"
Well if you compare it to it's Lexus / Genesis/ Infiniti rivals you shouldn't have to drop the engine down to do a timing job.
I agree on the OCI being way too long!without a dipstick you can't check the oil quality not just the level, or the presence of gasoline, metal or coolant in the oil as telltale signs something is failing.
@@speedkar99The New Toyotas and Lexus with the problematic 3.4 V6 are being serviced the same way. Drop the engine and transmission with the subframe or in the case of the Tundra, completely de-cab like a Land Rover.
IIRC, the extended oil change intervals exist because so many German cars are leased and/or oil changes are included for a few years on new vehicles. So the manufacturers decided to they could save money on these “free” services by extending the time between them. They don’t care about the long term effects, the car will be out of warranty by the time the engine fails.
The problem is that car manufacturers have different priorities than owners should. The manufacturer cares about getting through the warranty period. The owner should be interested in maximum life but alas unfortunately this is mostly not the case.
This is bullshit. Anytime an engine has to come out it's always bad for the consumer. The mechanic shops will open a regular person wide open in the rear😅 just bad designs. This is why I'll continue to drive gm v8 vehicles. I don't have to worry about major labor like that ever. I'll stay away from newer vehicles. They aren't practical for daily driving.
They'd make a plastic thermostat spring if they could
Don’t give them any ideas.
The next gen engine will have plastic pistons
If it's all plastic, they can delete oil.
vw r&d department are working super hard on making plastic pistons haha😂
If there's one thing I've learned from this channel, it's to never buy an Audi. Not that I could afford one anyway. Now every time I see one on the highway I think of your videos and wish that driver the best of luck.
Most people will lease it and throw it away after 4 years. It's the budget baller who buys it after that that has to foot the bill
You should do a collaboration with erik from I do cars. Between the two of you, I have learned more about engines than I ever did in school.

12:52-The dipstick is behind the steering wheel in front of the left front seat back. Or right front seat back on right hand drives.
Cant call out the audi engineers, they designed it all exactly how corporate wanted it; powerful, smooth, and just durable enough to live past the original owner (who traded in/sold towards a new audi), to encourage people to buy new cars. Well engineered doesnt mean well made, sometime in the 90's I feel like the germans became masters of planned obsolescence.
OH YES, the LEGENDARY german engineering! Beautiful...
Overengineering to make it impossible to repair
They just put it together using current three steps : 1 Does it work? Tick. 2 Will it last to the end of warranty? Tick. 3 Get it out of the door
@@rasklaat2 4. Convert metal engine components to plastic? Tick
Legendary trash
@@greathey1234 Overengineering is good design, this is not.
Really good one, enjoyed this. What a complex POS. Really had to go out of their way to design that kind of complexity. The oil filter run is comical, and WTF with those intermediate pulleys, makes the Porsche IMS look intelligent.
Glad you enjoyed. They sure did alot to this engine to make it different, in the name of efficiency and weight savings.
Great channel !!! In awe of your knowledge and ability to explain in detail the content of your videos. Thanks !!!
I'm glad you appreciate it. I've got lots more videos like this, check them out!
What a monster of an engine, ugh! Loved your wiring harness removal tool by the way.

A couple of months ago, I pulled up behind a Q5 at a stoplight that appeared clean and newish. It did a slight buck and died. The owner managed to get it started after some strange noises and a puff of black smoke and then accelerated quickly away. Daily life in precision German engineering.
This video is a masterpiece. Everything was touched on and explained clearly.
I'm glad you enjoyed it!!
well there's plastic and then there's plastic.. but of course they always choose the cheap plastic, thanks for the video!
Agreed...it will eventually leak, if it doesn't blow up like this one!
Great video!
I own a Q5 with the 3.2 2010 model with about 112k miles. Have owned it since new. It’s an Interesting car for sure!! Definitely have money ready for maintenance if you buy one but they can be Very Very good cars if you get on that was maintained properly and not abused. They handle Incredibly well with the Quattro AWD. The Audi 3.2 TFSI engine is one of the Only engines they ever made other than the 5.2 v10 that has variable valve timing on both intake and exhaust side and variable valve lift on the intake side. It is a higher maintenance engine, mine uses about a quart every couple thousand miles the oil light comes on. Most don’t add oil and go way over 10,000 miles on oil changes so no wonder these engines fail early. Plus it’s a high compression engine that requires 91+ octane and most use 87 or 89, it pulls timing on that which isn’t the best for the engine it seems to like 93 octane the best. I average 28 miles per gallon with mine. I replaced the headlights which were almost $1000 a piece, all 6 injectors 3 at a time I believe that was over $1000 and then replaced one of the coolant lines the plastic piece where they like to break. Other than that the car will absolutely drive in 5ft of snow in a snow ban and make it through especially with the Quattro AWD and snow tires it’s a Beast in the snow it has about 11”-12” of ground clearance underneath. It sits higher than the newer ones which I like
i have nightmares from this chain setup, thank you for the video
My 2009 A5 had this engine. One of the first things I did when I bought it was to buy a real dip stick.
You can buy a real dipstick but you can't buy a real reliable vehicle lamao
@@mann_idonotreadreplies I think Audi are pretty reliable. I have owned 3 and never have any surprises
A little JB-Weld and the engine is like new! 😅 Very interesting video. Thank you!
It makes for a good coffee table or conversation piece.
The knock sensor must have been working overtime at the end of the life of this engine 🙂
Very nice carnage!
The only Audi motor that was really built for longevity, durability and reliability was the 2.5l five cylinder motor. Which you can only find in the new Audi rs3. Vw used a non turbo version in their jettas for awhile and what not but they no longer do. However the Arabs actually petitioned vw to keep making the Passat in their region with this motor due to it being such a good motor and being able to service it and work on it so easily so vw still makes the passat with the 2.5l five cylinder motor in it to this very day but only in Saudi Arabia and the middle eastern region. So you can still get a passat with the 2.5l five cylinder motor in it if you import a middle eastern passat.
I still will never buy a VW product ever
its interesting the gulf states get the special bits. Either that particular five cylinder motor in the later models, or the "dubai lamps"
I remember in grade 9 auto shop, taking apart an in line 6 Chevy and putting it back together...very simple motor...glad I became an electrician lol
I genuinely want someone to tell me the last engine they saw that had fully metal timing chain tensioners. Everyone complains about them, but I've literally never seen one that isn't plastic on the guide surface itself. Even the 250cc SOHC engine on my ATV that dates back to the mid 80s uses plastic on the guide.
Great
Driving on the highway at "80" mph...
Con rod: I'm free!
In the directors cut of blade runner it is revealed that those replicants only live for a couple of years because of the plastic parts.
Yeah, sad.
Lots of retired old school mechanics says” i never use any fancy tools to figure out problem in a car back in 70s”
We i guess they never seen sh*t like this back in 70s
Yep. This is mostly in the name of emissions

You should teardown a VAG VR6 Engine, the 3.2 or 3.6
I'd love to get a VR6!
Really interesting video, what do you think could have been done to prevent this happening?
Buy a Corolla
Frequent monitoring of oil capacity and condition, and add some if the level is getting close to minimum. Changing the oil and filter after every 5600 miles or 9000 km and pick something which is recommended for the actual brand's engines. You can usually see the one or more brands on the bottle, also if it is recommended for petrol or diesel engines. By the way this is the highest mileage you can do after an oil change, 5000 miles or 8000 km is better, and even if you don't reach such mileage because we are speaking about a weekend car, you need to change the oil after every single year since the last change!

The inspection hole was better XD
I thought I misheard that at first
Haha came to the comments for that too
I have one and it hasn’t given me many problems at all. All I got to do is the timing and it will run forever.
I don't understand why Audi is still a popular brand in Europe... very costly to keep running..
It's popular because it's the iPhone effect. They think it's premium but it's not. It's absolute overpriced German trash

Why do they put the timing components on the back of the engine?!??
Variable valve lift on the exhaust side only.
It’s a delight watching your videos ❤
Long story short. Buy simple Japanese
Not all Japanese motors are good.
Honda used to make good engines until they went turbo
@@speedkar99 I dislike turbo’s in every day use road cars and ya, Honda coming out with those turbo’s were a big No No for me. They themselves learned their mistake and understood why it could be detrimental to their legacy of producing cars that practically run forever with the adequate maintenance, they’re now slowly reverting to NA engines as much as possible. I know 1st hand because I own a Jazz as well as an Octavia. Getting rid off the Octavia soon. It’s warranty is about to expire. And the Jazz, 12 years, over hundred thousand kilometres and no troubles so far.. And the space inside the Jazz simply put D segment sedans to shame. Keeping it forever..
Disposable cars..... you wouldn't want one that's out of warranty..... pro tip: download some fairground music so when you're sitting on the shoulder waiting on a tow truck you can squint and the blaze of warning lights will remind you of a country fair and bettter times....
My little brother bought an 8 year old Audi....after telling him not to many times.
Personal crank shaft valve 😂
Judging by the varnish...owner had champagne 🍾 taste but only beer 🍺 money 💰 🤑
Owner was too successful to bother with oil changes
someone actually said hey this is a great idea for an engine lets build it with these chains in the back of the engine /what a mess and a great reason to never buy an audi without a full warranty/now i know why i see so many q5 audis for sale with under 100'000 miles
Yes, German engineering at its finest
Haha
Vorsprung durch techniq hahahahaha
ANY valid idea as to why oil dip sticks are being deleted? It's 7c worth of steel. 🤔
No one checks them. The electric sensor is more likely to alert someone it’s low. I have a few cars with them. For all the hate they actually work fine.
Those engines seem to have been expressly designed for the purpose of being as unnecessarily complex as possible. This engine must have made some interesting sounds when it blew up. 😅
The EA837 Series. (3.2 V6, FSI) They are reliable, if only they are constantly been monitored; frequent oil change, monitor timing chain guide, monitor air intake carbon build-up. You will be good to go.
don't forget all the plastics...
@@joskd8491 yes you are correct, i wish i could find aluminum die cast of it.😂😂😂👍👍👍
Constant monitoring ≠ reliability

@@masontee8335yes bro
Why chain's are not plastic?
daaaaaaamn i feel bad for the folks who bought these cars used ouch
Do you think Audi engines are the most needlessly complicated? Seems that way to me. If there's a motor/brand that one-ups them in that, what would it be?
They’re all complicated at this point. I’d say Volvo with their turbo AND supercharger is probably more complicated. Really despite all the hate most of the German engines do OK. Leaks and plastic BS you bet can be a pain, but I’ll take that over the Ford issues with the EVERYTHING EcoBoost (especially the 2 liter with the defective block design) and heck GM and Chrysler can’t even build reliable V8s anymore. Hyundai can’t build any engine to be reliable either, especially the Theta 2. Really unless you’re buying a Corolla you’re gonna deal with some BS… might as well be something you don’t hate to drive.
German engeering always disappoints.
They always impress me that they actually implemented this in production
Sure would of like to of heard that baby go south. Pretty sure the driver needed a change of shorts. Holy complexity Batman. Wonder just how many kW's of electricity it takes to manufacture just one car?
That must have been quite the fourth of July 💥💥
That part of the lobe for driving around city is probably never used by anyone that has Audi 3.2l engine. It is to much to expect from someone that barely reads to obey speed and noise limit.
Pretty reliable for a VW/Audi.. well that says enough. Don't put the bar too high eh?

This proves engineering schools are not teaching engineering students to actually engineer.
I bet this failure happened at idle in the drive thru on the way to church. How os your neighbors house coming along?
They're still building it! The outside sheathing is done and it finally has windows. It seems like they ran out of money part way on it as it slowed down quite alot.
Nothing says German sustainability like me chucking out a barrel full of used up oily plastic garbage engine parts going straight into the landfill everyday at work… yep. That’s where all the gaskets covers o rings one time use cheap metal parts yep all into the trash. Every day. Nonstop.
Agreed....they want to be environmental responsible yet these plastic engines cause more landfill waste
AUDI - Amazing Unreliable Driving Innovations
I am sure this thing blew up at idle 😄
It sure did. Idling at 5000RPM. 🙂
Hate the no dipstick crap, I have the same on my A4, relying on the computer to tell you about your oil is not reliable.
Agreed! And you can't tell if the oil has mixed with coolant or is worn down because you can't see or smell the oil either.
@@speedkar99"trust us" 🤡
@@speedkar99Yeah, but consider that almost no one checks the oil. With the sensor it’s monitored 100% of the time and you can alert the driver if it gets even remotely low. Ideally you’d have both, but I have a couple cars with electric only and it’s really no big deal and it’s handy to check the oil level when you remember it while driving.
Yes Yes Yes a catastrophic failure. I mean the design. Maybe the same folks designed our financial system too.
😅😅
It seems to me this was operating as designed by Audi
I will never buy another German car in my life ever
Good engine but trash placement of the timing chain the v8 is also is the same sadly so the lesson of the day is make sure you service your car

Very advanced. Too advanced!
This is 2.8 FSI not 3.2
It came from a Q5 which only has the 3.2
@@speedkar99 I apologise, you are correct 👍 very similar to 2.8
This is why you never buy a gdi motor. Direct injection causes more problems than it solves and ask for just a like more horse power.smh. It’s stupid. If you want a vehicle that’s gonna last a good long time don’t get a direct injection motor or a cvt transmission unless that cvt transmission is connected to a motor with only 3 or less cylinders. Just cuz it’s new tech doesn’t make it better tech.
CR turbo diesels suffer the same. TDI, TDCI, etc. I just recently cleaned the intake on my 1.6 TDI and it was absolutely gross.
I blame emission laws
@@greathey1234 emission laws are the major contributor to these design changes unfortunately.
@@tedsteiner you would think people would wake up to the fact that much of these energy saving ideas applied to cars and refrigerators end up shortening the life of the car or appliance, which then has to be replaced prematurely causing the use of more resources to make a new one than any piddling savings you reap.

most. modern engines are full of plastic why? if its so obvious that its a bad idea??
Cheaper production, which also generates more money with frequent replacements, not to mention the ridiculous price. The finest part of capitalism, simple as that...
@@staLkerhu Ah yes typical side effects of capitalism !!!!! We must maximize profit no matter what
@@gorgonismztruth1551 It's the lack of capitalism. Remember, these engines are required to meet emissions and other standards set out by governments. Capitalists aren't telling them what to build, the government is. If you disagree, just take a look at any EV.
They chose plastic also because it's lighter than metals and that weight savings translates to something. I don't want plastic either, but when inflation is rampant and the government is dictating their build criteria, they're not designing for you and me.
Weight. As simple as that.
@@thesis4349 weight huh? I'm afraid you have no clue. So, they wanted to save weight, that's why they designed the block with a 90° bank angle instead of 60 or 65. Yeah, sounds about right.
They did both 90° angle and plastic parts to save money... 😑

unnecessarily complicated design
For a reason, so you will spend thousands fixing it usually at the stealer or just give up and buy another
It's a different culture in Germany. Consumers brag "My car stayed in the shop over a month last year and it took a team of technicians to repair it because it is a complicated smartly engineered machine."
Reality is they aren't too complicated to figure out but the level of quality hit rock bottom and stayed around the late 90's when Toyota and Honda killed their profits. European manufactures couldn't make a piece of plastic/rubber or electronic module worth a flip to save their lives. Resale is low for a reason.
ALL ENGINES ARE BAD LOL
So much for great German engineering, people have been getting conned for a long time, it's seems if you want a good engine go Japanese
I’ve had a bunch of Japanese cars. The German stuff drives better to me and some of it actually is pretty great. The BMW N52 and B58 are both pretty rock solid overall. Having owned both for more than 10 years (n/a) I’d put an N52 on the same level as a 2jz, but with WAY better fuel economy. Also have an Audi… it’s NOT on the same level as the BMW but that’s mostly due to BS non-critical electronic gremlins.
