if yuo change cabin heater core yuo may also change ac core also

I grew up in Plymouth, graduated from Wayzata HS class of '09. Life long Audi enthusiast. I seem to remember an Emerald Green S6 saloon that was around Plymouth in the late 90's and early '00s. There were a few UR cars in the western suburbs growing up. Dad factory ordered his '14 S4 from Audi Minneapolis with a manual gearbox and nothing else. Ive got a '14 S7 with some OEM + improvements. Interested in finding a clean URS4/S6 saloon soon, preferably one that is built or at least full RS2 treatment. I now reside in South Alabama on the gulf coast.

Nice job. Also a reminder there is a coolant hose that runs under the intake manifold that can fail. Additionally you can read the codes by using a jumper, and counting the blinks on the dash. So you don't need to buy the software to get the codes if you have the check engine light on.

My heater core just broke on the inside and all the coolant was going to the air vents on the inside. This video helps me a lot. Thank you 👍🏻👍🏻

Great video! I just got my hands on a URS6 and I am very happy, have wanted one since high school. It does however weep power steering fluid out of the X plug on top of the power steering pump, do you by chance have the P/N for that seal in there? It is difficult to find as you said.

this sucks; I want to see coil packs replaced

Im 18 and I daily drive my c4 s4. Its a dream and I have someone in Sweden who can sell me all the parts I could want! So parts for me aren’t that much of a pain

I need to locate my amplifier to fix, would you know where this part is normally located inside the car? (my car is a 95 A6 avant). Thanks.

You remind me of my boss. This is an awesome find on youtube. We have a 95 s6 in right now thats got the gremlins. Might have to contact you if you know about them like the s4! I had never even seen one before, pretty neat car!!

Ah, a fellow man. I do have urS4 Avant too as daily. Cool car, with 600hp you wont be annoyance to others. Its sometimes nice but sometimes i dont have time but when i walk to my car after grocery store there is sometimes some dude waiting and want to talk about the car :D have gained few friends with that

Can pretty much guarantee these were damaged during a spark plug change. If it is the same as the 4.0TT in the C7 RS6 then these connectors control the solenoids for the cylinder on demand process. The PCV system may be having issues if it is going through oil, forcing too much blow by into the cylinder. Either that or sticking rings, although this is pretty rare as far as I know. Cylinder 5 issues also had a TSB issued via a software update to resolve the misfiring. I know this is now 7 months old and hopefully you'll have had it sorted by now!

Oh how I wish I lived in the US sometimes. Here in Norway a nice example of any S2/S4/S6 pre 2000's is going to be $15k or more :(

Almost a year ago I traded for a 1994 jade on tan C4 S4 with 179,800 miles. It has meticulous service records from 2001 to 2012 and then it sat until the previous owner to me got it running right before I got it. It's very stock and only has a few noticable aftermarket parts on it like the red hose your S4 has, a new o2 sensor, and a weird aftermarket wiring thing in the driver's footwell that as far as I know, isn't connected to anything anymore and hasn't been for a long time. While watching the video, it was kinda funny listening to you listing all the parts that are almost impossible to find now that are mostly present on my S4. Also Audi 100 exterior door panel trim is a perfect substitute for an S4's if you don't want to get aftermarket ones. Obviously since my S4 sat for over 10 years, it needs some love to be a reliable car again. For instance, none of the interior doorhandles work except the driver's door and one door doesn't open at all, it has a stumbling idle when cold, it needs an entire brake job and both rear calipers seem seized, it needs a thorough tune up of course, all fluids changed, and belts, pullies, and the water pump changed, and a paint job. However, it drives down the road (below 45 because of the brakes) so fantastic, other than the basically square ancient tires of course, that it shocks me it sat for 10+ years. I don't plan on perfectly restoring the car, even though it has great bones and very little rust (formerly a CA car), but I would like to get it to the point where I could daily it semi regularly. Thank you so much for making this video and other very informative videos, I know they will help me out very much on my S4! 😊

I just recently bought an Audi s4 c4, but it’s a pain to find body parts for this car. I’m 18 and I’m trying to restore this car it has some rust on the fenders and side skirts. Do you have any recommendations for parts?

When you usually do a timing belt and you replace the cam seal, do you do it after the new belt is on and in time or do you tackle it before fully digging in to the rest of the job. Just curious as I need to do my Timing belt and cam and crank seals

Hi from Estonia. U allso have diagnostic mode on AC panel. There is information abaut faults, tempretures, speeds and so on. It is werry interesting video. I wish the best ! Thanks

Hello from Russia. I own two years of Audi s4c4 92 years, mine auto on the automatic transmission and also stock)

I bought my emerald/ecru '93 in early 2003 and daily drove it for five years. It was only mildly tuned, but managed to make it work without inflicting undue stress and headaches along the way. My experience was that the car was exceptionally reliable, but my example was a two-owner, extremely well-cared for and pampered, and I admit that I paid quite a bit for it.. However, it was more than worth it, as I didn't have to deal with any major failures or exorbitant degrees of "sorting out" of issues along the way. I would totally buy another UrS, if they weren't as old as they are at this point... And I *only* say that because parts have only become harder to find, with many completely unavailable. And that'd be OK if I were going to make a garage queen out of the thing, but I want to drive it, and drive it regularly, and spiritedly, and that usually means replacing parts every so often... And I wouldn't want to find the car on jack stands for months on account of one or two virtually non-existent miscellaneous obscure little components. I can't tell you how tantalizing I find the idea of an AAN-swapped CQ or 4k or, hell, even a spicy modified V8q with a stick.. God, I never quite grew out of my "Audi phase," even now over 25 years since first catching the bug. But at this point, the scarcity of parts is *the* single, major precluding factor, effectively preventing me from making the jump back into the community. I will forever be able and more than willing to wax nostalgic about 80's/90's Audis (and VWs, for that matter), and will forever defend those 4-ringed models when debating the merits and virtues of enthusiast vehicles from that era... But, barring some remote and almost unimaginable circumstances, it's unlikely I'll be buying any of them again any time in the foreseeable future. (Unless, of course, something really special pops up, then forget everything i just said 😂)

Just bought an allroad with a 2.7 Just change the oil and it's filled with glitter Needs a rebuild now

When I was a kid back in 2005-06 my dad had a yellow C4 S6 which I just loved. And before that my uncle had a Audi RS2. So to keep the tradition going I am obviously looking for an S4 or S6 my self. But as you say, these are challenging to find, especially in stock and nice form. And to make it even harder for my self, I live in Norway. And there were few cars that were originally sold here due to the high import tax. But your video has definitely helped me on my search to find one that is perfect for me, thank you!

That was a lovely example. What's the deal with those amazing number plates over in the states? Wish we could have those over here in the UK. Private plates here are hard to find and expensive. And we have stupid rules meaning plates are age related and can't be retro fitted. For example, you can't have S2 on an S2 because S was 1998 year and S2 production ended about 96.

Pretty clean. I own a 95.5 S6 Avant, saved it... it was a non-runner. Exterior is really rough, mostly just the clear coat failing. But no rust. I swapped the ecru interior for a black interior from an A6 Avant. The old ecru interior was tired, worn and falling apart.

Nice find. Looking forward to seeing more on this.

Great find! I love the way the 04 S line looks. Perfect daily/winter car for your son! I think the C5s are some of the most comfortable and solid cars on the road.

It’s your piston rings. They’re stuck and allowing oil into the cylinder which is causing the misfire. You’re welcome.

I recently bought an S6 AAN swapped audi 100 avant . Thank you very very very much for the information :)

NEVER heard another word from LaMettry's to see if they could make this right. No response to Google review as well. Avoid them like the plague.

Not a big fan of these coils, especially on such a factory clean car like you have. There is no performance gain under 400hp. That and the old school chips were used to the factory coils for dwell. On top of that the dwell issues causes starting issues when cold, at least with 1.8T / 2.0T coils.

Replaced mine a while ago, super easy peace of mind!

nice

Great PSA. Why daily that cream puff white car in the winter? Isn’t that a job for the Europa A6?!?

Excellent thank you for this! OEM Intercooler, turbo, and wastegate, overview would be interesting as well as your EFI LS2 coil conversion step by step.

Thank you! Going to do this on the S6 at the same time I do the check valve/connections, pcv, elbow, etc.

Good PSA. I've always replaced them immediately when I pick up a new UrS4/S6 car. In fact, my S6 had a small leak from that sensor when I picked it up, nothing drastic.

Another excellent video thank you! Just wondering is there a specific product you like to preserve the axle and steering rack boots? Also an episode on sensors would be much appreciated!

Well done sir. Your cars are beautiful.

I had one of these new ones fail in about a year (or two)... right out of the side. It started a pee stream on the side, all over my engine. I've since pulled a few of the older reservoirs from junked A6s, and threw them in my shed.

Dang, just started shopping for one. That wagon looked amazing. Know of any urs4/s6 for sale around mn? Heck even Midwest?

Good commentary! I've had... geez... 4 UrS6s, 2 sedans and 2 avants. I just bought my first avant back and am going to restore it. Gotta sell my S2 Avant now.

I have one door unable to open from the inside, one from inside and out and one that got stuck so it wouldn’t close once during a frigid winter day. Needless to say audis and vws for some reason have fragile door handles

Hahaha the thumbnail is mad! ❤️🇩🇪

Great tutorial. This walked me all the way through the process on my 96 S6. The valve broke apart just like you said it would, so I just have it bypassed with a 4 inch fix pipe from the FLAPS in the meantime. I had no problem accessing the red/blue plugs through the radio opening. Didn't even have to unplug and re-enter the theft code. Great job - and thank you!

does anyone who owns a c4/b5 still have good running cruise control lol?

I just paid $250 for a genuine Porsche coolant tank for my 944. The only other cheaper choice was a Uro for $150. I forgot to look to see where the Porsche part was made, but I bought it hoping to would last for another 20-30 years. I recently replaced the radiator in my B5 A4 😊 with a Mahle-Behr radiator. Again, I didn’t see where it was made. It’s discouraging that Mahle is getting stuff from China. I bought my stuff from FCP Euro for the lifetime guarantee.

Thanks man! Your content is 10 stars. Incredible value and you made me confident to go, look, check, test and buy my first S4. Don’t know how to thank you.

Hi, thank you for your video. I think your thoughts on the lacking support from the factory are true. It is getting a little bit better because of Audi Tradition here in Germany, but overall not near Mercedes and BMW. That is a shame, and a reason to keep the values of these cars down…

My first car was a 95 a6, pearl white with all black interior. Besides how slow it was and how badly it eventually started to burn oil i absolutely loved that car.

Is it mandatory to remove the whole box just to replace the blower motor?

“Ermf 💪🏽 from the dealer” 😂

Weren't the wood Vavona red burl instead of walnut? That's what i though i had in my S4 and i made a gauge pod using vavona veneer on a maple block and it was exactly the same as my trims.
