This is my car featured in the video, yes it was an expensive repair bill. However Tom was amazing and the car is back to how it should be. I had to save it.

This is great public service broadcasting that should help reduce subscriber buyer remorse. You come across as an honest, trustworthy and knowledgeable vehicle repair business. That's a great credit to you all, especially is todays murky world of car repairers. Thank you.

Very cool video. I have a 2005.5 B7 S4 Avant manual (US spec) and I paid 5,000 USD for it with 190,000 miles on the clock. It was in INFINITELY better condition than this one. Makes me really glad I found it when I did and purchased it. I had no history on timing chains but I figured for the miles on it when I bought it, it nearly certainly had to have been done. It still only rattles for about 2-3 seconds on a cold start and then quiets right up. Currently sitting at 226,000 miles and going strong. It burns a lot of oil at this point, but I'm sure the valves seals and piston rings are tired. I did do all the thermostat and water pump housing and o-rings, valley pan gasket, oil filter housing o-rings and oil cooler o-rings a year ago. Overall it's been one of the most enjoyable cars I've ever driven. It's not fast but it sounds fantastic with catless downpipes and a full Magnaflow resonated RS4 exhaust. Glad to see you guys keeping these old beasts on the road. They are a treat to drive.

Self lubricating chassis is a feature of Audi's

Great video and thanks for sharing the costs, which should help people understand how much it actually can cost to fix these cars. Al;so, sharing the profit helps people understand, but you maybe could have shared how much time you devoted to this so that the ‘haters’ understand how much effort you put in! Keep up the great work,

Mate this video is worth 10 million pounds! Just absolutely and informative and well rounded video! Really well done job sir, congrats!!!

My son has a B5 S4. I totally concur on everything you just did. Nice work!!

This was SUCH a helpful video. Not only did you talk us through what to look for but also what to LISTEN and LOOK for with examples! A+++. Thank you. I loved my Audi but had to get rid of it when things started to go south. Sold it to my mechanic as he know he could fix it for less and make a good profit. Win win…But I have wanted to buy another because I loved it and it looked amazing. Thanks.

As someone looking into buying a used audi, this video was very insightful and helpful! Thank you very much!

The comparison of rattles is invaluable! Thanks!!!!!!

I bought an rs4 b7 2006 in 2013 absolutely great car and other than an auxiliary radiator was bad I didn’t have any problems phew they can’t all be bad but the more I look into Audis I realise that maintenance is so important and just can’t be left more importantly than on other manufacturers Always great videos Thanks guys

This guy definitely a Audi wizard, top man 🙌🏽

Great video - in my opinion, the price and your labor was a steal, well done. Love my B6 S4 Avant, nothing out there like it, love seeing people keeping them going.

I thought about buying one of these in the past… This guy is awesome… And if I were to consider in the future I’d certainly heed all of his recommendations. Too bad I can’t find a mechanic like this in Cincinnati Ohio

Very honest work and costing. Sounds a lot of money but for the amount of work and cost of parts that’s normal.

I must say excellent channel and information on what to look for, repairs are never cheap especially like your work is first class👌👌👌

I dont even own an audi, or planning to in the new future, but i appreciate the honesty and the transparency. As some people sad in the previous comments, these are rare attributes in todays world.

Example sounds are the best thank you

Great work! i agree with too much work on this car. For years, I have been buying CPO cars and let the dealer take the risk. Yes, I pay more but the Audi's I have bought like this, (4 of them) two had almost 300K on them and the other two over 130,000 miles and running great. My A6 with a 3.2 has 267,000 miles with original timing chain too.

Even though I drive a BMW 435d I absolutely love this channel ❤️ did own a 2009 a4 at one point and was a great car 👍

Really like these S4/S5 videos👍🏽👏🏽

Brilliant informative video as usual, my b6 S4 is dripping oil for fun at the moment, not got round to looking at it, but your tips certainly help, keep up the good work and I may be contacting you guys in the very near future 👍

Great work guys! Love the content and the car looks great 👍

Love your video, planning on buying a b6 s4, will definitely look out for these issues

My mate has just bought a black on black RS4 Avant. Bloody lovely. Changed his mind on an RS6 on my advice. Hope he made the right choice.

Brilliant video, Love your content, having owned a b6 s4 for 6 years they are very expensive, apart from timing chains, mine had steering rack issues, engine mounts which were torn in half, air con shaft snapped, gear for the air con in the engine splines were no more, power steering pump wine, gearbox linkage issues, good car but for me they are too old now

I’ve had several Audis over the years 4/5 and 6 cyl engines but what I see here really puts me off them.

Great video and great info on the S4 b6/7 cars, thing I notish the past 1,5 years i have one that all S4 have the same issues, so when its done its done and taken off the bill you always get when you own one. Like check valves, leaking oil filter housing seals, leaking power steering return hose, valve cover seals, intake manifold flapper noise, external radiators leakage, a/c unit bearing and so on and so on. It can be a pain in the ass sometimes but you forget it all if you are driving it with a big smile on your face, realy nice cars.

I live in Australia and I am looking at buying a B7 S4 and if I go ahead I will fly to the seller and drive the S4 back home a 1600k trip. Glad I found this clip on YT now I know what to look for and have made a list to ask the seller. Even if I don’t buy I did hit Like 👍 and subscribed 😁

Great video, very informative, and nice work taking all that work on. Most shops here will decline doing 4.2 timing chains... Also love how most of the B6/7 dont have sunroofs!

great job with the s4! really enjoyed the video on saving the s4! I have an rs4 and spent 10k euro so it could drive it happily. If only Im in your area I would of brought it to you seeing you have a great knowledge and passion! New subscriber added!

fantastic insight! thanks for this one guys!

Very informative and true 👍🏻 good work

Still my dream car... very informative video

great video, especially part with engines sounds.

Good to know I dodged a bullet or two when I bought my b6 S4. I bought it from a dealer with warrantee but I still went over the car and no problems whatsoever. Only thing I don’t love is the slightly vague steering and clutch feel which can be fixed with aftermarket attention . . .

Currently going through my B6 S4, pretty much every issue I've found was brought up in this video. I've never seen oil leaks cause so much collateral damage, every rubber part under the valve covers was toast. Definitely didn't know what I was getting into when I bought it.

I have enjoyed a lot to see your amazing job, how you do a complicated job looking easy, thanks for share a lot of details to do during the jog, Adios from Spain

My S4 B7 does what that grey B7 S4 did on start up, I was really worried but now that you said that I’m kinda relieved.

Congrats, excellent video, regards from México.

Good advice. Will help to reduce the amount of people being burnt buying these ticking time bombs of an engine.

B7 RS4 is a beauty.

good final word

Such a fun car to drive! Drove a new 2006 s4- 4.2 V8. So great to drive BUT NOT engineered to last. Fun to drive new. Shit longevity

Fantastic work m8

Excelent! Congrats!

Sound advice very interesting video 👌👍

Looking for a RS4 B7 soon , brilliant channel ,👍

Great stuff!!! B8 rs5 and dsg gearbox issues next please 🙏

THESE GUYS ARE AMAZING THANK YOU SO MUCH FOR YOUR VIDEOS AWESOME 👌 👏 👍

top notch info from you

Excellent video 👍👍👍👍👍

Awesome video 👍👍👍👍

On mine with 108k miles, replacing the front cv shafts, the upper suspension links were extremely hard to get off because of age, wear and tear, etc. The a/c went out at around 100k miles, and to replace it you have to remove the entire front end and try for hours to break the shaft loose from the compressor without turning the shaft. Absolute dream to drive, requires a decent amount of maintenance even if you get lucky with timing chains. With that said fixing things is pretty straight forward and only takes about a day for the bigger projects like the a/c and valley pan oil gasket.

Great video thanks for sharing 👍

Miss my B7 S4 sometimes, but then I remember how bad it leaked steering fluid and oil and any time I took it to the shop it was >$1k for anything. And also getting 12 mpg in the city with gas prices where they are now was no fun. My experience with the B7 was like having a super hot but very toxic girlfriend. Sex is great, but all other times you hate her. They’re so much fun to drive and sound so good but it was a stressful experience turning the car on every day, who knows if it started making a new sound that would cost me a couple grand.

Great video 👍

Got my A8 D3 for 3,000. Flatbed straight to mechanic. 2,000 to get it running. Drive to next mechanic to fix rear brake caliper and intake manifold gaskets - 2,000. 7k in, has 185,000 miles. I love to drive it, just hope that it does not fail around the next turn.

Awesome video thank you!

So glad I sold mine

Daaammmnnnn!!!!Thanks to you I'll stick to the supercharged V-6s ;)

bro you re a legend for all of this. you and carwizard (that fat dude with glasses) you two and scotty kilmer are some of the most solid car dudes out here on youtube.

I come back to this video about once a month to check how my S4 B6 should sound like under the bonnet. Seems like its all fine today! Thanks for the comparison of the chain rattle!!

Just spent £1000 on front suspension parts on mine. Definitely not cheap cars to run! One other thing to look out for is the tailgate on the Avant. The struts can be pulled from the bodywork or be bending the bodywork before they fail. Your glovebox will be broken…or already broken and repaired. Love the V8 burble though, and a magnitude easier to buy and live with compared to an RS4 of the same vintage.

Excellent video, the dead spider joke cracked me up :'D many ppl don't realise that these cars might be cheap to buy but maintenance wise just as expensive as a new S4 and the added wear and tear makes it even more costly game let alone negligence by previous owners.

Great video. I have a k04 B5 S4 and a noggy B6 S4. It's a great car. I've only had to swap a sensor or 2 over 130k miles. I've got to pull the motor still and do the cam chain job. Not looking forward to that job

Great advice

you guys do a great job! one-day i am sure to bring a project to you :-)

Cracking video

Great cars 👍

had all of those fixed on my S4 and sold it immediately, Thats the biggest maintenance bill I ever had for a vehicle, i really miss that B7,

About to buy a s4 hopefully alls mostly good with it

This is certainly a film which proves the point 'buy on condition'.

That moment the VAG group implemented those foamy supports inside the front fender/wing wells, they made a huge mistake. Collects all the moisture and dirt and thats why they all rust on the top part of the fenders.

One little thing to add to the b6 buyers guide. The headlight back caps are incredibly fragile and can crack apart just from sitting. This lets water into the headlight causing electrical faults. New ones for the passenger are nla as far as I can find. Luckily some genius has designed a 3D printable version. Once I get my printer set up mine will be getting a set

Very knowledgeable

Great video, but take a look at the wheel arches of a 20 year old Mondeo or Vectra and these B6/B7 models have taken the road salt quite well.

As the old saying goes.. "It's not the buying a car like this that's the issue, it's the running and maintaining of them that's the problem".. My B7 RS4 is on 136000 miles now, got it 9 years ago with 89000 on it, in my ownership i've changed the oil and filter approx every 3000 miles... as far as i know still on original clutch and timing chains.. no noise or issues with either.. so far. Apart from wear and tear items the most expensive part to replace was the oil cooler and lines. Brakes, suspension, suspension arms have all been done by myself, but i wouldn't even have a go at the timing chains on one of these... I take my hat off to you sir.

Jesus.... poor car. Really thankfull for all the info you guys are sharing, the 2.4 v6 engines can have these problems as well? I'm referring mostly to the timing and engine issues, leaks and suspension parts are to be expected on aging cars

Awesome 👌

I picked up a B6 A4 v6 convertible for 450 bucks and am in the process of doing the work on her .. engine and suspension are done, exhaust and transmission range sensor and fuel filters are next up. Get them cheap and do your own work.

Nice video. I have a B5 and am in the market to add a B7

I have a b6 and both sides of my valve covers went dumping oil fast and everywhere. It happens a lot so get those valve covers changed religiously!

Looks great (I’ve sub’d too). B7 RS4 Imola yellow owner.

Enjoy your videos, thanks for great talks as well. I have a rs4 b8, 114,000 km. Everything looks fine, car drives great. See lots of the dsg gearboxes has got trouble in the VW and Porsche applications, and Audi ? When do I need to think about timings chain replacement etc? I stay in South Africa

Rule of thumb, never buy a car with a dead spider in the engine bay, it means it's never been looked after. (Not the spider, the car hasn't been looked after).

I will never own an Audi because I’m poor but this is fascinating information. Audi’s really do seem like over-complicated junk.

The 4.2 is a good motor, but the cooling parts and small mechanics go wrong and break often, very expensive upkeep. Owned one and spent thousands

Could you do one on a q7 3.0tdi out of all the videos I’ve seen you really know your stuff and can be trusted so who better to do one

Great video thank you. I want to ask about suspension kit, is Lemforder the best? There are other brands available for half the price is it worth it? Or what would you recommend?

Very accurate

Kralju!! Dali imaš preporuku gde mogu naći service book za 2003 allroad 2.7t? Ovde u USA nigde ne mogu naci. Keep up the good work, love the chanel!

Just like any other car you have to Maintenance it on a regular stay on top of it Audi has a site with the what you need check on your s4 every certain amount of Miles

Almost everything he said about the engine gasket and arms happened to my old s4 B7. Except for rattle.

here in the states a good condition 4.2 s4 than NEEDS the timing chains go for around 4,5,6k+. The ones that are in good condition and have the chains done are around 9,10,11,12+. I'd like to get one eventually before they are all rotted.

Make a video about the Audi Rs6 C6 with V10 TT!

Thank you for the EXCELLENT VIDEO! Having had THREE B6 S4s (still have one), this video pretty much sums up my experience in a nutshell. The money I spent on these out-of-warranty cars was horrendou$$$$$: one engine swap, too many suspension parts to count, oil leaks, steering pumps, etc etc. (The first two had some chain noise but I didn't even get to that.) And to fix the last B6 S4 I still have--an '05 Avant from the northern US--will require an engine pull to replace the cracked performance headers. Why are they cracked? Because the car was too low. But why bother doing any of that when the car has visible rust. I'm sad because I can't drive it and it's a mechanic's special now :(

Million pounds later :D Oh my god i can just imagine the repari bill for that black avant S4. Nice video again btw!

on my car it can diagnose by it self condition of chain, i could replace it but mechanic told it is ok, as new, because i replace oil more often, every 5-7000km

At what year did they upgrade the timing guides to metal brackets? I have a 2012 Audi A8 with the 4.2 and worry about having timing chain issues?
