My neighbor has this car in this exact spec aside from the blue interior. It sounds incredible every time it passes my house.

Former Audi Tech here, the headers are factory, which is definitely cool. I personally think they probably played a little fast and loose with the emissions, as during my time as a tech I had to replace quite a few cats that failed before the 8 year 80k mile warranty period. They flowed really well though. Valve covers were also factory. The traction control light should also reset automatically after the traction control computer sees input from all the wheel sensors. You shouldn't have to crank the steering wheel, it just needs to learn wheel speeds after the dead battery replacement.

My Forman at audi had one of these. Same spec. 280k miles and the car was still immaculate! Sold it to a friend who continues to drive it. Gorgeous cars

As a Sprint Blue RS4 owner myself, I cannot be any more excited to watch you work on this!

USDM, EURO, JDM. This man can do it all! you're one of the few channels that never changed up on its viewers and I honestly never got bored of watching you.

I got to spend two days driving preproduction RS4 mules at The Spanish Grand Prix Circuit in 2006. The brake calipers had the Lamborghini logo on them as they were off the Gallardo. They wanted us to limit the revs to 8k even though 8.5k was no problem. These cars are an absolute blast on a race course. The sound of that 4.2 V8 on song coming down the front straight made the hair stand up on your arms. The RS4 is a very special machine.

I see alot of comments saying Alex bought it, he sold alot of cars, and now bought this RS4, and so on... People, pay atention to the video, he literally begins the video with the words "my FRIEND bought" He also hides the licence plate because it's not his. But anyway, even if it was his, so what? He earned all the cars he wants through hard work and being an awesome dad and husband. And this is quite a special car to pass by if it's a good deal.

43:40 Now I finally get the fogging oil for men reference from M539 Restorations 😂

I was expecting this to be a one hour talking video about restoring the car and then you making 18 part videos of you restoring it. But turned out to be one really good video where you restored it. Fantastic way to make a video. I appreciate this setup. Thank you!

My sister and brother in law have a 2008. With 30k miles. Swapped in the KW suspension. I’ve driven it a few times, and it’s a ripper. Great car.

Valve cleaning is like bong cleaning. Lol.

Best Audi ever made. And possibly one of the greatest sounding engines

That milltek exhaust is worth a lot of money for that engine and car !

The trick with VW/Audi electrical connectors is push the release tab at the back down, then push the connector IN then pull off. Don't use a pick or you can break the internal locking plastics

Current automotive college student here, got into it from your vids (and engineering not working out lol) and bought myself my first fun project car 03 Audi TT Quarttro. Love seeing some audi love on the channel. Much love from southern IN :)

I've been requesting an Audi on this channel for years 😂

This car is 100% going to be a future classic. They are just so beautiful and an amazing package for the time period. They handle extremely well, they feel pretty balanced and the powertrain is awesome. Cherry on top is they look fantastic. They are so wide and aggressive looking for the era

I learned how to drive on a 2007 Audi s4 and it’s such a great car to drive. The Audi rs4 is greatest super sedan, manual transmission v8 ever made

You will never financially recover from this. I love it. Can't wait to see the build.

Where my Audi people at? Whatcha got?

One of these used to roll past my work at the same time every day, I would go running to see it as soon as I heard the rolling thunder of the 4.2 echo off the buildings. Core memory

I love Audis, I cannot afford Audi maintenance, but man, the driving experience is unmatched. Your friend must be stoked

Thanks Alex for inspiring me to get back under the hood. My Dad was a mechanic, so I did most of my own repairs when I was young, but life got busy, and cars got complicated , so I hadn't turned my own wrench in years. I stumbled on your channel a few months ago and when my CEL came on recently, I decided to buy my own scanner. It said the code was my upstream O2 sensor so I got the part and got back under the hood. You're right, the click of my torque wrench is pretty satisfying. Got it done and my car is running perfectly again. Thanks for getting a wrench back in my hands

Whenever I watch these kind of videos, I just want to leave my office job, get some training in car mechanics and open my own shop. This is so satisfying to watch, especially because I am also a proud owner of this beast.

The 2007 is definitely the last of the really good RS4's, I've driven one many times my brother owned one with a super charger and 800 bhp, The only real problem is the clutch if you boost it. They're fantastic it's like riding an angry bear.

I owned a B7 S4 for a couple years and I miss it more than ever! Nothing better sounding than that 4.2 V8. Thanks for showing us Audi boys some love!

I just finished my 2nd Audi B5 build. My first one is a single turbo converted, built engine, link ecu, 700hp on e85 2001 s4. My new one is a 1998 a4 with 2007 rs4 engine and 6 speed swap. With the original mechanical quattro from '98....dude....Its nowhere near as fast as my '01. Not even in the same ballpark. But i love it sooooooooo much more. The car weighs 2840 lbs with me in it. The weight reduction is pretty aggressive but it does have carpet, a/c, and a good stereo. I did a link stand alone ecu again because they're amazing, built some really badass stainless 2 inch primary long tube headers, stainless x pipe, out of a Lamborghini murcialago muffler i mounted behind the rear bumper and exits in the middle. It made my little black Audi sound like something from the depths of hell. Everyone asks me what the hell i have under the hood. I show them a bone stock b6 rs4 engine and they freak out. Seriously, if you want your car to sound ridiculous, buy a used Lambo murcialago muffler. I dont know what it is about that car in particular but, the mufflers are very very special. They completely change how any engine sounds. Im confident a vq35 would sound awesome with one thats how much it changed the sound of my car. It sounds identical to an LS with an 8:1, insanely counterproductive and power robbing, elh setup. If you've ever heard the Passat Tanner Foust used to drift, thats EXACTLY what my car sounds like. Wasn't on purpose. I had my fingers and toes crossed the first time i started the car. The second i whacked the throttle, even my wife looked at me like "damn...someone's getting lucky tonight." Shes a rich girl from a small town. The smell of race gas and tire smoke give her goosebumps. I shit you not. She thinks the fact im an automotive fabricator is SEXY...the fuck is wrong with her?

My buddy in high school had an ‘08 a4 s-line 2.0t 6spd manual and that car was a blast. I cannot imagine what this RS4 variant is like. What a great car…. Now to finish the video! 😂

Miltek stuff is extremely high quality. Audi UK will offer this as dealer fit equipment I believe. My best friend owns an Audi specialist and fits Miltek systems frequently! Nice to see them stateside. These respond well to supercharging.

I've noticed thru the years, that higher end vehicles tend to have a "2 stage flasher" using your term and for lack of better. This only happens when battery voltage is extremely low. My 2011 infiniti m56 does this, and will actually turn the hazards on automatically if voltage is too low. Happened to me last week. Drove for work, got home, locked car, went to bed, in morning hazards were on and i could not turn them off until vehicle started. Great show. Dispise german stuff, but love what you do. Showing the backyard mech, even high end vehicles can be fixed with minimal tools. Good show sir!!!

The more I watch your videos... the more I realise how good a mechanic you are. Your attention to detail is just top notch... excellent.

Alex: Park it over here so it looks like its been abandoned for years. Lot guy: But I just washed it... Alex: It's fine, no one will notice.

Those were not cats, they’re the front resonators. Same setup on the Audi RS5 B8 and 8.5. The RS5 was the last of the naturally aspirated Audi V8s, and the engine is quite an upgrade from the RS4. I still love the RS4. It’s a cool looking sedan and great to see this example rescued.

Part of your problem with the CRC direct injector cleaner is it needs the airflow and heat of the engine. Just spraying it on the valves does a lot less. As I always recommend read and follow the instructions. I actually recommend using the CRC from the get go with DI cars and have it as part of the maintenance program on every 3rd oil change. For my customers I run it through do all of the driving and heat soaking then do the oil change. I had a customer who moved away the shop in his new town told him he needed a walnut blast he had 5hem show him proof. They pulled the intake and the valves were spotless. He called me to get the schedule for the CRC. They refused to do that service for him. Now he drives 5 hours for me to service his car again.

This is the content I am here for, Alex. Finding cool cars that need that require your expertise to make run/nice.

There is nothing in this world that could make me trade in a manual V8 RS4 for a Tesla. N-E-V-E-R. This is my partner's dream car. Hope your friend loves it!

Audi/VW and Benz have a special place in my heart. I love BMWs but it's a love hate because I've had to work on a n54😂

I can’t get over how much remind me of the automotive version of Mark Rober! I just started watching a couple days ago and I am hooked. Don’t ever change!

I had a silver one for two days because I borrowed it off my stepdad and I absolutely loved it. What an absolute monster of the car. The only car I’ve ever driven like it which I’ve owned for many years is a golf VR6 they are so good I wish I could afford one again

That valve cleaning is so satisfying to watch

That's been badly abused. Such a great car too! That raw naturally aspirated V8 is the last of a dying breed! SAVE THAT CAR AT ALL COSTS!!!!!

6:12 "These old German cars can go NUTS if you have under voltage issues and THAT battery was BAD!!". Oh man can they ever. My buddy had a car that had so many engine lights that were on on his BMW and he was so panicked that the car was a goner!! He was seriously freaking out!! He called me and said "My car is wrecked! It's done! I can't fix all of these problems!!". LOL. I told him to just "Hold on I'm comin". (Just like the song LOL). I have an app on my phone called "Protool" which is German car specific. So I knew it had to be the battery. So I took my battery out of my car and out it in his then erased the codes and wouldn't you know it all he had was a couple of air bag and seat belt I think codes. It was crazy how nuts he got! But he had never seen anything like it so I couldn't blame him. The first time I saw it I was freaked out too! and I ran it through and erased the codes and all that was left was the low voltage and some other

That engine made me so much money over the years. I can't count the amount of timing chains I've replaced. Good times

Damn best mechanic ever, rescued and fixed the car with fuel cleaner and laptop lol (feels staged) it’s to clean and perfect for something sitting for years

Wow. Best car you've ever had on the channel. I can't wait for this build.

nice to see the 4.2 V8 + 6speed manual 🔥

Awesome! Good job saving it, you never see these on the road anywhere anymore.

I know sometimes it doesn't translate very well on film but that car looks too clean for it to have set for 3 years in the same spot

B7 RS4, one of the Audi´s GOAT... Sweet thing this, loved the video!!

Here's the link to the Performance Improver. You can use this to clean valves or just pour in your tank! www.amsoil.com/p/amsoil-p-i-p...​ This is the cleaning kit with the brushes. amzn.to/3LBLwn2​ This is the blue air blower I used. www.carsupplieswarehouse.com/...​

I'm freaking out about that S-10 Blazer. I'm in Canada and all the ones here are 4x4 and rusted to heck.

I remember the video where you first introduced us to your new shop here, you were so excited! That was what, 2 to 3 years ago? You've come a long way! Good job! ♥️👍

awesome video. long time S4 and S6 owner here. Impressive skills and knowledge. Just take shit apart, fix/clean, then put back together, no matter the brand or model. props.

What a car ! Please more Audi's ❤ I remember trying it in 2006, was very impressed.

Give her the old Italian Tune Up, Alex!

Your English is spot on, the right direction to grow your channel but with a build this exciting that will take care of itself, that space frame is a work of art 👌🏻

Here's the next RS4 video! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ImlkhwR8jIs.html

Used to have a -05 A4 with the 3.2 V6, Avant and a 6-speed manual with quattro. Absolutely love Audis. Especially in this color!

Pretty clean for being in a field for 3 years

So cool! And finally, manual transmission

My favorite color and model rs4 ever!

Hey Alex buy one of the refillable self pressurized tanks and buy a gallon of brake clean for 20 bucks and you'll save a ton over time! I hope we see more of that Gwagon that was in the background in that car lot.

Its funny to watch the likes go up in real time on a Saturday morning. It's like Saturday morning cartoons, but for adults.

Been sitting for years 😂 looks like jus came from the car wash 😂 engine bay super clean anything for clouds 🚙

Glad you brought up the walnut blaster for cleaning the valves, my buddy uses one and they come out crystal clean!!

Next time pour dry Ice (CO2 cold)to harden the carbon then pour hydrogen peroxide then pour vinegar and wipe it’ll melt off the carbon incase u wanted the liquid that cleans it

THESE are the videos we know and love!!!!

I had one of these. The variable flap system often fails due to the cheap plastic on the arms breaking due to age/weakness. I had my system removed which is actually a good top end power increase modificatio when the ECU is tuned to suit 👍

Thank you for the RS4 content. Not enough!

I can't believe you didn't clean up the "rodent mess" before you started working on the engine! It would have driven me nuts to still have it there!!!!

That first start after the valve cleaning was satisfying.

Rescue that GMC jimmy beside the Audi. Sweet 90s suv.

Long time subscriber, long time audi fan. I daily a highly modified 3.0t supercharged S5, this is peak content for me. Thanks for rescuing this sweet car.

Former 07 gray owner, it’s good to see this. Can’t wait to see DRC/other suspension and other restoration.

My favorite thing about Saturdays.. love the videos Alex

I've learned more from this channel in 1 year, than 3 years as a full-time professional technician at Ford & Chevy.

Had a Milltek on my 2004 S4 sedan. Drank / burned oil like crazy (quart added every 800 miles basically). Predecessor of this car, so fun, and sounded awesome.

Alex is the type of guy to ride around listening to Rick Astley's never going to give you up unironically... 😂😂😂

🇺🇲 Hey, from Vermont. Yup.Born 04/05/1969. Love your content brother. Thank you, Travis

When I did my RS6 valves, I just used raw petrol and it worked great. I then finished it up with the walnut blaster after getting the majority off manually.

Alex: "I have to sell cars for a new shop....but look at this car!!!!! Ohhhhh maaannnnn......!!!!!!! Ahhhhhhhhhhhhhhh"

14:51 dont the intake look cracked? nice to see a audi on the channel cool car alex! :D

I had one of these in Maguello Blue, loved the way it revved, perfectly spaced gearing, that gave you a little neck snap with every shift. Had to get rid of it when the economy tanked. I miss that car so much!

Alex: " I'm selling off all my cars so that I can move into a bigger shop." Alex 2 weeks later :" I just bought an Audi at the auction!" LOL! 😂

That car was “sitting” for three years and you just drove to the shop??? 🤔

It’s possible they have been cleaned before being parked up, by the looks of the mods on the car it looks like it was loved at one point so I’m guessing it cleaned.

Let us know if your wife likes the new cologne.

Boy, you have patients, i work on my vehicles myself. I get sick when i just do little things like changing oil. I have 5 to maintain.

0:07 Sitting for 3 years 😂😂😂.............................NOPE! 🤡of the 🌎

One of my dream cars. These cars are awesome. I'm glad that you're bringing her back to life. Sometimes our cars just need and deserve a little love. From that to a Tesla... Ugh

One thing I’ve regularly appreciated is that (on Audi/VW) it seems like once you break the initial torque of bolts, they come out pretty easily after that. Might be a convoluted mess of tubes, pipes and brackets, but they’re workable.

Thanks for your videos. I've started working on my car. Recently cleaned the throttle body. Granted it's no Audio, BMW or Porche, but was great to do by myself!

Can't wait to see more episodes of this car, stoll watching it over n over again 😅😅😅😅

I am super jealous!! Blue is my favourite colour and I really like that generation RS4 (although I like the avant/wagon version better). Getting something like this is my dream one day maybe...

I'm literally a April 5th baby and have 3 mercedes, the type of mercedes a 20 year old could buy 😅, love the videos man, keep it up!!!

Had my C6 RS6 V10 for just over a year now, a wagon with a 5.0 twin turbo V10 in it, love it so much!

I'm not a German car fan, but that thing is sweet, doesn't look as complicated as I remember, when I used to work for an independent shop..

These cars are incredible. I love everything about them aside from their fuel mileage

As an Audi owner, I am so glad you finally did a video on it! I’ll be on the lookout when you put this one up at auction!
