This is a teardown for the books! Some of you have seen this engine floating around in the background of previous teardown videos. I've been avoiding this one for a month or two, and have burned through all of my "easy" engines. Decided to rip the scab off, and get to this 5.2L BXA Audi V10 core that came in. I knew nothing about it. It was cheap, not a high risk engine. This was filmed over 3 different occasions, and required a lot of on the fly research to get it apart remotely correctly. I'm hardly an Audi or VW guy, and this is the first engine of this type I've ever torn down.
The 5.2L BXA came in the Audi C6 S6 starting in 2007. They are rated 435hp and 398lbft of torque. Personally, they seem incredibly complex for the power they make however they do sound pretty amazing. This particular engine was pretty pooched. Whoever was behind the wheel when this happen tried to power through whatever the situation was, and it wasn't the right call and it likely cost them their car as it was junked after this.
I really hope you enjoyed this teardown, it was a lot of fun to learn how it came apart both the right way and the wrong way.
As always, I appreciate all of the comments, feedback and even the criticism. Catch you all on the next one!

This is comedically accurate if you’ve ever worked on any of their 2000’s V8, V10 engines. Nothing disassembled easily and is even harder to re-assemble because you’ve forgotten where and how components go back together after it took you a week to disassemble it, a month for parts to arrive, and then a week in meditation to motivate yourself to work on it again.

I sold VW/Audi's when these came out. First, what an amazing engine when you give it some right pedal! Second, what a maintenance and service nightmare. You most definitely do not want to service this thing out of warranty. What I always was amazed at is when it came to relatively expensive vehicles like this, how hard it was to get people to service/maintain them. Even with free maintenance we had to call and hound owners to bring their vehicles in. Audi had (I can't remember exactly now since it's been many years) either 15,000km or 20,000km oil change intervals, in North America where people do not check their oil ever. On a high output performance engine. Ummm, yeah. You are correct, almost everything WAS engine out. The service department had motor trays/jigs for lack of a better term - tech would put the car up on the lift, raise engine tray/jig to engine and/or transmission and disconnect everything and just lower it down. They could do it pretty quick on all models since engine out was the norm for most things. Was common to go into the Audi shop of 6 bays and see 4 vehicles engine out. Crazy. And that uber complicated timing system with the A/C running off of it. Just imagine the shock to the system every time that cycled on. The noise this thing must have made as it blew up surely echo'd off buildings for blocks. So, what did I learn after working for Audi/VW for years? Never ever own one of these things out of warranty.

[@robertmason8341]

You got that right, about outta warranty ownership. It’d cost a small fortune to go thru the timing system and replace everything. Typically why people off them right before or soon after off warranty. Let someone else deal with the inevitable. Now on the flip side, to someone like me who has the facilities and capabilities to work on them, they have their place and can often be picked up cheap enough in very nice condition with the presumption of going thru and fixing/replacing alot of high dollar stuff right of the bat as preventative maintenance. That is when the price is sooo right you just basically budget that into what your not spending on buying the car itself.

Once there, you have to remove the driver's side engine mount and then you can work the shaft driven compressor out.

Overhead cam engines are always so complex with lots of potential breaking points.

[@ejkk9513]

It's honestly not that complex. I'm very familiar with them. The actual internals of most Audi engines are very strong. The components around the engine... not so much. The 4.2 v8 engine in the RS4, for example, has a closed-deck block with a ton of reinforcements, forged pistons, forged connecting rods, and a forged crankshaft. It can handle an incredible amount of abuse. This V10 is also very tough. I'm not sure how this one met its end, but most likely, it wasn't maintained properly. My Audi engine has over 120k miles on it, and the internals look brand new. There's not a single stain or varnish on anything. I've had a ton of issues with everything surrounding it, but not the engine itself.

[@ftffighter]

@@ejkk9513 I used to own a 2005.5 Audi S4 with the 6-Speed Auto and loved that 4.2L V8. First thing I did after buying it, was swap out those junk plastic timing chain guides for the metal RS4 guides/tensioners. I ran it from 98k miles to 127k miles with zero issues, until one day it was 15 degrees below zero and the coolant reservoir broke in two spots pretty much draining the engine of coolant... had to get her towed somewhere and she got stolen :/ Yea, it sucks. Smoothest engine I have ever felt, the V10 is probably even better!

[@ejkk9513]

@ftffighter The coolant reservoir in all Audi and Volkswagen cars are designed to fail. I have replaced them on every single car that is over 10 years old. Like I said, internals are strong. Everything surrounding it is crap. Purposely so. I've driven a Lamborghini Gallardo with the 5.2L V10, and it sounds lovely. It's actually not that smooth because it's a V10. This design is inherently prone to vibration. It has problems with primary balance, and it has an uneven firing order. A V10 has to have a V angle of 72 degrees to have an even firing order, and this V10 has a 90-degree angle without a split crank journal. Audi uses a balance shaft to counter the balance issues though. The Lexus LFA is the best balanced V10 ever made. The 72-degree angle used is perfect. I love the sound of most V10 engines, but on an engineering level, they have some serious challenges.

[@ftffighter]

@@ejkk9513 Yea, I definitely figured that out the hard way. Breaking at both ends of the reservoir at once was pretty bizarre. The cooling systems rely on plastic couplings, not metal, in order to "Expand" properly under heavy loads. The worst part is, if you do end up using metal on one piece, it'll just add more pressure to the other plastic places. Which means you ideally have to replace all the joints with metal or you're stuck with using plastic still. Not to mention, aftermarket isn't the greatest so if you used metal you'd have to manufacture the parts yourself. Not sure if that would cause anymore failure points do to improper expansion of the system too. So, you're kind of stuck with plastic. The plastic does seem to work well as long as it's maintained properly and the pieces are all checked ahead of time for cracks and failure points due to long-term wear and tear however, so it's not like it wasn't engineered well. The design is fairly solid and kind of cool when you dig into it, but you are right though... the plastic is designed to fail long term. Don't get me wrong, you CAN bulletproof these engines/cars in the end. It just depends on how much you umm... "Love your car" per say XD.

Highly entertaining teardown, thanks. I've seen far worse "shrapnel" and Involuntary Self-Disassembly Products in my days working for a race engine company. Including an F1 piston that let go at 18000rpm, after which no piece of it was larger than a pea. Usually I was in the design office, but visited the engine build / rebuild workshops regularly. On one memorable occasion, an 800hp 3.8litre V12 had broken a rod at 12,000rpm, destroying the cylinder bore and breaking the block. It was bleeding fluids on a build stand, awaiting teardown. As I took a closer look, some education expert was giving her opinion on the radio: "The word "failure" must be banned!" she adamantly insisted. "There is no failure, there is only 'delayed success'." Ignoring what she was trying to say (about avoiding being negative regarding any child's future development, and encouraging them to keep trying instead, except she had not clarified that context), I looked at the guys at their workbenches and said, "In that case, I look forward to this engine's delayed success..." Seeing the (relatively minor!) devastation of this engine reminded me of that moment when an engine failure became an engine's delayed success.

[@Lammergeier350]

Wow! I'm not much for the German varietals, but this is a rare treat indeed! Decently reliable for what it is, and I am a huge fan of the concept of stratified fuel injection. The only issue, of course, is dealing with the carbon buildup that is a problem on all direct injected engines (a problem with a solution that I love: simply add another set of injectors in the ports). From the moment I saw the mechanical re-gapping and the amount of buildup in the ports and on the plugs, I suspected a typical third-owner 'run it until it breaks' mindset. Green coolant, worm gear hose clamps, and varnish buildup tell me that it wasn't professionally maintained, which means that there is a decent reason that the S6 loses 75% of its value after just ten years. German complexity and a lack of reliable aftermarket, coupled with not a lot of shared parts with their 'lower' offerings means that these engines are destined either for destruction or overly-expensive maintenance. The number of times I've heard something along the lines of "just because I drive an Audi doesn't mean I have Audi money" on a five-year plus old model is both heartbreaking and infuriating.

The timing chains on the back (and a lot of the rest of the design) make a lot more sense if you consider this engine in the R8. In a mid engine car, the front will be against the firewall and the back will be more open, usually they have a small access panel in the car's interior to have access to service belts. Audi taking this and slapping it in a sedan equals service nightmares/engine-out for everything, I'm sure the fancier and more expensive sports car is actually a lot easier to work on, ironically.

Every german car mechanic passed these 3 years car mechanic school 2 days a week and 3 day at the car garage) . BUT a car mechanic for these AUDI is adittional trained some days/week at a special AUDI school to service + repair these performance car. Third = I think the Audi (and no name garage) know that is is normal to build the engine out of the ... Even if he spend one day for these work plus one day to fit it under the engine compartment. For difficult work it is easy and he can do a better work. Remember the owner is person with higher incoming and is able (and will) pay a lot of money. The owner know these. These is a performance engine in an performance car for sales man. He will use the abillity to drive unimited speed level at these parts at the german Autobahn with no speed limit. And the owner is able to pay the premium 98 ROZ (normal he drive to shell with 100 ROZ or ARAL petrol station with 102 ROZ). The highest prize petrol is good enough for him. I think in US you can not get these quality petrol. In germany you can get these at ervery petrol stations and at Shell or ARAL petrol station these top level petrol. By the way thise is not a special raceing petrol. The owner is able to drive with these car 200 mph at german Autobahn. A lot of owner say = well 155 mph is enough for me. An Audi R8 V10 is a sport car. These engine you find in a bigger size Audi RS6. You drive with you wife and family shopping. Enough space for the shopping and the children. And use these car for your daily long distance was to your customer as a premium sales man for big companys. Service nightmare for the car mechanic = yes The owner know the amount of money and can afford it. The Audi garage know these and say ok we will sell these service nightmare. We have a skilled trained car mechanic with addition AUDI school training. If you are not a trained AUDI mechanic leave your fingers away. If you are not a Space ship mechanic you leave normally you fingers out of an space ship aswell. If you are only able to service a american V8 well and ok. No problem for me. By the way I never ever but my fingers in these Audi V10 or Mercedes perfomance engines (or BMW performance) because I dont like these engines. But if my boss send me to these special traing schools for these performance cars ... Well then I really like to work with these engines. My boss will buy all the nice tools for that car. Enough working place and enough time to work. And a computer with direct access to the car manufacturer plus telephone hotline to constuction engineers. Only fighter jets and Space crafts mechanics are better .... These car mechanic are toplevel trained ... If a low budget garage or an unskilled garage owner is the boss of the car mechanic ... well When I am a owner of a Audi V10 engine and I go to a Yugo garage ... 🙃

In 2003 Audi came out with the B6 S4 4.2l and I believe that engine was the first to have the timing chains in the back. I read that they did this because of packaging issues. This looks to be about the same setup. It's unfortunate they had to go this route because the 4.2l timing belt motor I read is supposedly a boom proof motor. I bought a S4 with a 4.2l in it. It had a new engine form Audi installed. The bill was over 30k for that new engine and install.

I don't believe that is correct. IIRC the Lambo and the R8 have the engine flipped backwards in the car so that the transmission sits in between the seats. This means that in the car, the timing chains are still up against the firewall.

They made it thin to reduce the moment of inertia. That's a posh term for the spinny equivalent of mass. It gets weird when you spin things, two parts with the same mass can easily have different moments of inertia, depending on how that mass is distributed. The one with the higher moment of inertia will require more torque to spin up and slow down. So it's good to keep that value down in order to sap less power from the engine under acceleration, especially in the lower gears. It's also a directional thing. The axis of rotation is the basis for calculating the moment of inertia. The same body can have two different moments of inertia if it is spun around two different axes. In order to get a complete picture for an arbitrary body, we pick a point on it (usually the centre of mass), apply a coordinate system (aligned with axes of symmetry, if there are any) and calculate 9 numbers. Those go into what we call the inertial tensor. "Tensor" is just a posh word for a sudoku square where the 9 positions mean something to mathemagicians. Three of the numbers that go in the tensor are called the _principal_ moments of inertia, those are about the X, Y and Z axes of the coordinate system we invented earlier. They go on the diagonal of the square - X is top left, Y is middle and Z is bottom right. If the body is symmetrical about all three axes, then the other components become 0, but that's rarely the case unless by design. The other components represent what happens if we were to draw a diagonal axis, such as one between X and Y. Let's call it XY. The number from that one goes in the top middle box. But because XY = YX, it also goes in the middle left box. In that way, the two triangles formed either side of the diagonal tend to mirror each other. Anyway, having the whole tensor lets us do cool stuff, like moving/entirely changing the coordinate system without having to recalculate them from scratch. Instead we can push them through any of a number of transforms (depending on the change) that will give us the correct values for the new coordinate system. Modern engineering would be absolutely impossible without the gigachad mathemagicians who came up with all of these general solutions long before any of us (physicists, inginerds, etc.) knew what to do with them 😁
