Ivan should be able to afford a good vacation after fixing this Audi 😂
Deserves one to
more then 1
Gonna need one too.
YOU CAN START A WHOLE NEW CHANNEL WITH THIS ONE CAR
Customer's wife called - husband ran off to Bahamas with girlfriend.... Nevermind fixing the car....
It would be cheaper. Depending on the girl, probably more fun.
My aircraft mechanic was paying alimony, so he would give me a cash discount so he could hide money from his ex. I'm only a few years out of school at this point so still a little naive. One day as we're having a beer at the end of the week, he tells me, "If it flies, floats, or f***s, it's cheaper to rent than buy."
@@major__kongthat explains why my sheep rental business has taken off.
😂
PS, keep the car as payment.
Ivan, you've been killing it with this series. Really enjoying the content. Merry Christmas!
Merry Christmas! Enjoy the final few episodes :)
Ivan, you HAVE to tell us the final billed amount for this car! I think we are all curious!!
a shitload...
Or at least the total labor hours.
whatever the cost is the owner will have a working car that most couldn't repair successfully at any cost
This Audi is one strange bird. Nothing on that thing is “normal”. Kudos for you and your skills tackling this monster Ivan.
I couldn’t believe that new blower motor had a loose washer in it! So much for quality control.🤔
Final inspection is down to the customer these days 😂😂
That was uber shady😮
Zebrano is the name Audi used back then for the fancy wood :). In terms of the ECU, you should see some of the mods/chips people make for the older 10vt cars. Very interesting stuff! What you dont see is the moisture trap which should be just a bit before the hose meets the ECU. Anyone who is an enthusiast but has not worked on these because they are intimidated need to watch these videos. Amazing how simple some stuff is when you break it down. I've said it before, but these things are amazing highway/road trip cars. The only thing this one is "missing" would be the front sport seats. The comfort seats are ok but the sports are extra bolsterous and more comfy. Looks like Ivan has given the green light for more older Audi's to invade his shop! :D
Hey Ivan, love this series. Would you ever consider giving us a toolbox tour?
All 4 drawers of Harbor Freight tools? 😜
This Audi is a treasure trove of content. Great diags and repairs. Thanks Ivan. and Merry Christmas to you and your family.
Just wait another year or two when all the probe pierced wires start to cause problems. He should've used liquid el. tape. 😀
This guy is going to have way more in this car than he could ever get out of it. He's just going to have to drive his investment out of it! Thanks Ivan!
That's the plan... Drive it and enjoy it! 😎
Ivan: This is(different)". Saying it nicer.
Also Ivan: It all came apart and was actually fixed fairly easily in the long run.
Funny how that happens...
I've ridden and raced dirt bikes all my life. I've had pretty much every brand of Japanese bike and some Euro bikes. Yes, the Euro bikes are put together somewhat differently(but the converse can be said if you went the other direction). I currently run a Vintage National cross country series and have Husqvarna bikes. Funny thing is, parts are readily available for the Huskys and they're pretty easily fixed with general 'stuff'. I have much harder time getting parts for the Suzukis, that we're much more plentiful here in the States back in the day. Fixing them can be more of a problem today.
Also, those that own the Kawasaki KLR650 love to complain about KTMs having problems, yet they readily talk about their prowess in fixing age old problems the KLR continually had that were never addressed by Kawasaki. Seems kinda funny when you stop and think about it.
Then the rest of the Japanese crowd complains about the cost of KTMs, then you see them putting thousands of dollars into tuners and suspension work on their 'cheaper' bikes, then 6 months to a year later they're selling them because they can't make it into a KTM.
It all depends on your perspective when you look at things.
Ivan was able to fix up a 32 year old vehicle that sat for quite a while. Yes, it took time and some patience working on something he was unfamiliar with and that unfamiliarity caused some frustration, but it was fixed with general mechanical know how. I'm sure it cost the guy a good bit to have Ivan do all that, but considering what new vehicles cost, especially EVs, well... It was a drop in the bucket. Good luck replacing the batteries in an EV 32 years from now(and even presently when your Hyundai Ioniq hits a minor object in the roadway 😉).
I just knew that the dirty, gunky fuel tank was going to be an issue right there at the strainer on the fuel pump. Just watch a few episodes of Vice Grip Garage to see how critical it is to have a clean fuel tank. 😅
Euros really aren’t my thing, but strangely the more of these I watch the more I find myself liking this car. It’s actually pretty cool and in great shape for its age.
Yeah it kind of grew on me as the project progressed... Got more fun on each test drive 😎
I was joking about this being a 12 part series for the 12 days of Christmas.. But it might actually happen. :)
This Audi is the gift that keeps on giving. The ECU uses MAP, which replaced AFM…most modern cars now use MAF.
aftermarket ecu like megasquirt, fueltech, and racetech use MAP. much better for turbo cars. think they copied from Audi
@@PatricioGarcia1973 yes; I have a Megasquirt ECU I built. MAF sensors are very dependent on the size and configuration of the intake; MAP does not care. So, for an aftermarket ECU, MAP makes much more sense.
While MAF was historically common on early fuel injection vehicles (Bosch etc) now it is mainly a US emissions thing. There are lots of vehicles worldwide from a multitude of manufacturers that use MAP instead. Some, for instance Mini (on the R56), use MAF for US emissions compliant vehicles and MAP everywhere else, both equipped with upstream and downstream O2 sensors (one being a wide band sensor) The end result in terms of measured tailpipe emissions is more or less the same.
My 2016 F150 with the normally aspirated 3.5 (not the Ecoboost, I think it's called Duratec) uses MAP. Not an automotive engineer rather aerospace, but MAP seems like a much less finicky way of doing it than MAF.
I remember some Chrysler products had a vac hose going to the computer, probably mid 1980's.
Ivan this is your classic never ending story.
Oh, Ivan... feeling your pain. Back in the 80's I had a 5 cyl diesel Audi 5000. Beautiful car, much like a Mercedes to drive and great interior. But not easy to work on. To replace the heater core required a similar operation. That blower box was glued in and so hard to reach in that space it took much sweat and hours to detach. The only good part of that job was when I went to the dealer to pick up the new core I special ordered the cashier wanted only $80 instead of the HUNDREDS they told me when I ordered it. Being honest I said, "are you sure?" She confirmed the price and I was out the door with a big smile on my face, very relieved as money was tight. You rock, man!
This Audi reminds me of the very old SNL skit "The Thing That Wouldn't Leave". Thanks Ivan
Just some trivia: The Chrysler products from the mid 1980s had the MAP sensor built into their logic modules, which resided in the same place as this Motronic unit. They ran a vacuum line to it.
Let your customer know that if he's going to replace the wheel bearing or struts at some-point he may want to convert those UFO brake rotors at that time from a different year Audi / VW to get away from these parts he will have a hard time finding. I believe, if memory serves me right there are other VW/Audi options that you can convert the struts / wheel bearing / Brake system from as easy as swapping it all over. I'm sure someone online has mentioned this. I remember my dad did it some time ago for a customer (neighbour) in the mid 1990's. But as my late father is no longer with us, I can't ask him.
I can't fathom how closely the ECU manufacturer must work with the vehicle manufacturers to get the computers right! I tried to help a friend with a '96 Dodge Dakota, and like the Audi, it didn't have an OBDII connector. It did have some diagnostics you could access by turning the key 3 times quickly.
almost ALL dodges have that feature,., my 89 dakota has it too.. even some of the newer dodges have it.. my 2006 chrysler 300c has it. I think it was a factory quick check more than for the customer..
All 1996 and newer Cars and Trucks powered by gasoline are required to have an OBD2 connector. All 1997 and newer diesels also have to have one.
The Audi does have a diagnostics connector. You just need the 2x2 adapter so you can connect it to VCDS
The washer works, the engine runs good, gauges need a little work, but it's starting to look better already. You can see the light at the end of the tunnel and it's not the train!
Good one Ivan.
Ivan, if that cluster becomes too much of a headache tell your guy to go to someone like Clusters by Litke. He's in Warren OH and rebuilds the german clusters. It might be worth it to just convert the whole IP to new LED gauges. Great series!
On the mechanical odometers, you can usually disassemble it and move the wheels to the correct mileage. I was able to do that on a Mazda RX7 1980 speedometer with no trouble at all.
I was able to change the mechanical mileage on my 92 Cavalier when I installed an upgraded cluster that had a tach and some other gauges in it. I think I had to take apart the cluster to do it.
Germans don't make anything easy... Unit is assembled for life... Unless you want to saw through the case haha
One of my daughters had a Chevy Vega with rusty fuel tank, so I removed the tank drained out the gas flushed it out with water, put in a can of lye and filled it with water after a couple of hours I emptied it out and then washed it out and the tank was like new, no more fuel filter problems.
Seeing a lot of comments here that need rethinking. Ivan is showing this series, not only to teach (God forbid people learn something new), but also had the heart to take on this project for someone who wants to bring an older car back to life and not have a payment (while also learning what it took to repair). If you want to purchase a new vehicle every 3-5 years perhaps watch Scotty Kilmer. He has tons of “advice” for you.
Scotty Kilmer would have a heart attack if he found out how many expensive things had to be repaired to get this car back on the road 😂
The fact that ypu can laugh at a complete lack of quality control is impressive, Ivan. I would have lost it at that loose washer rattling around.
My last new car purchase, came down to Audi or Toyota. Went with the Toyota. Thx Ivan for confirming I made the right choice.
PS once i learned about the Audi "service configuration", which entails removing the front bumper, I was out. Might as well toss $2k out the window every time you drive by the dealer.
I have done heater cores on those, lot of fun! You Do Not have to remove dash. Great job as always my friend.
That’s not a repair, that’s a career ☺️🤓
If you can fix an old Audi, you can fix ANYTHING haha
@@PineHollowAutoDiagnosticseven an EV???
@@mikefoehr235 I’d say, Ivan could fix anything. Even an EV. Heck, they are all just electronics based and he’s a genius with that kind of stuff. Less grease and grime too 😉
@@mikefoehr235 I would argue that EVs and Hybrids are much less serviceable...either programming updates or very expensive component replacement. Boring and non-satisfying to own and repair haha
@@PineHollowAutoDiagnostics I wish you and Amanda a Merry Christmas 🤶 🎄
Real progress. Thanks Ivan!
There will be major progress in tomorrow's episode ;)
Nice catch! New parts that require intensive care get a bench stop. The owner must be second guessing this unit but no doubts it will be an exciting conclusion. Merry Christmas!
Awesome video series Ivan, thoroughly enjoying. Goes well with popcorn !
That hose at the ecm is a boost pressure sensor. If you open the ecm. You can swap the fuel and ignition chip along with the boost sensor with a soldering iron. We did that on my brother's old one. And swapped the turbo. Ended up just shy of 500 horse. That car would rip the tires loose at 4th gear when you hit the boost. It's a beast. I would love to find one to own today. I miss that car! Actually have some pictures if you want to see?
Man,you are a genius!!!. Thanks for all your helpful videos.
In 1986 my mom bought a 5000 S and paid $36,000! Sweet car but thankful that she bought a crazy extended warranty. Over $16,000 in repairs in four years! A deer did it in!
I worked in a dealership when those cars were introduced in1984. We were sitting around the lunch table and came up with a list of over 100 common failures on those cars. When they came in for warranty repairs the average repair was around $3,000.😮
@@needhelp2453 HOLY CRAP!!!
This project parallels my own experience on a 944 that sat for 8 years. Fun times.
Wow...awesome job...
WD40 is good stuff but you must have a different version than what we get in Australia. Our WD40 dries out over time so is no good for permanent lubrication.
Sounds the same as ours. Seems most people misunderstand this product, probably because it is cheap and ubiquitous at this point.
The product was originally developed to "displace water"...they nailed it on the fortieth formulation attempt...hence "WD-40".
It works as a penetrant but it is in no way a lubricant except in the very short term. Use sewing machine oil instead.
Ivan. This real car repair using basic skills to diagnose and repair often win no parts required. You are redefining the 12 days of Christmas. Have a Merry Christmas!
You have great access to the fuel tank from the top. Didn’t understand why it wasn’t cleaned out in the first video.
Because I wanted to make sure that the car could at least drive before spending hours on the nasty tank lol
@@PineHollowAutoDiagnosticsIf it has crap compression or a thrown rod at least the tank is clean, smh.
AUDI. Always Under Diagnostic Investigation... Lol. Ivan, so amazing your professional skill, diagnosis, and patience on this car! Great series!! Merry Christmas to you and yours!
That craftsman ratchet on the bench by the clusters is a match for you as you are a true craftsman~keep up the great work Ivan👍
I got to watch on my first day of Christmas vacation.
Great channel! My -94 VW T4 also have a vacuum line attached to the ECU.
Again great Audi Video Ivan .. for the fuel tank look into a fuel bladder insert that might be cheaper option and the only option if the fuel tank has that much rust and crap inside the tank its only a matter of time before the fuel tank will start with a bunch of pin holes all over the place and start leaking gas then you will have no choice but to replace the fuel tank
Or a plastic/ composite tank
Possibly a holley hydra mat. Tons of surface area
Nice work
Ivan, this is beautiful work as always. That said, you are starting to succumb to the profane talk that so many mechanics use in the shop. I'm going to take exception to that. I tend to recommend really excellent, informative channels to homeschool groups for their kids to watch. I can't do that with folks who have to mix sexual innuendo into their teaching.
Welcome to the real world haha!
Merry Christmas to you and your family, sir. Best wishes for a healthy and prosperous 2024. Thank you for the entertaining education.
I'm absolutely loving this restoration project. Thank you so much for sharing the experience with us. Now, about draining the tank. If you have a fluid exchange pump, those work wonders. If not, they are fairly inexpensive. There is no easy way to salvage a rusty tank. But you could help it along until a replacement if found. Once it's drained out, you could use some blue shop towels to wipe it down and use compressed air to completely dry it out. Use a stiff plastic or brass brush to loosen up the rusty bits and vacuum the rust out.
Worked for a major auto company for 30 years. 6 of which was in the engine control group. Never could have imagined a vacuum line anywhere near the engine controller. Crazy stuff..
Ivan your videos are great and hope you and your family a very Merry Christmas and a great New Year
Merry Christmas!
I'm looking for something special on this one because it's the _Eight Maids A-Milking_ episode.
Keep om trucking! , several aftermarket EFI systems have map sensor built into their control.
The owner of this Audi is a legend‼️💯
Adding some Gumout with Regane (PEA) will help clean a fuel system. Chevron Techron probably will do the same. I mix some Gumout with the gas in all of my lawn tools and they start much better after sitting a while. It cleared up a miss in my outboard FI 2 stroke. It helps keep the carbs clean on my antique carbed motorcycles.
I had a 1984 Volvo 245 wagon. It had a vacuum line going into the ECU which operated a diaphram
I had a similar issue with the mileage. When i swap the mileage i had to manually crank over the numbers to match original mileage
Ivan, to say you were only 5 years old when this Audi model came out how on earth did you find the knowledge to fix all this problems. You are definitely a (Guru Person) like your friend Keith. Beyond belief that you are fixing the car for this customer. Dave in Guernsey, Channel Islands.
Couldn't have done it without the wiring diagrams and OEM Service info provided by AllData! 😊
Also old fuel injected classic beetles we had here in Mexico have the map sensor integrated into the ecu! Very long hose from the engine to the ecu!
From about 1976 on certain engines until 1989 Chrysler had what was called "Spark Control Computer" and later "Lean Burn" computers attached to the air cleaner on their V-8 engines. (On the Police cars the computer was inside the car.) There was a vacuum line that attached to the computer. So, this Audi is the quirkiest car you have ever seen? This coming from someone who has worked in a 966? Yes, a Zaporozhets (ZAZ) 966. I get the impression you might be getting tired of messing with this thing. GREAT VIDEO!
The owner of this Audi has found himself a sucker to work on it.
I know I mentioned it already. But you couldn't pay me enough to deal with this craziness.
It would great to know how many hours this project took and appoximate value of parts. Your patience is amazing. Following you from Jakarta.
Hi Ivan great videos I have been learning so much about diagnostics on autos from your videos. I have question and if you do not mind me asking, could you please tell all of us how many shop hours you have in on that Audi. Happy Holidays to you and your family.
Ooohhh, the sound of those 5 cylinders 😍
Just wait until I add some proper boost to it 😎
A gift that keeps on giving... BTW Ivan, area 51 is looking for a few good men. You would be a perfect fit. Maybe reverse engineer some alien technology.
When I started out as an engineer, my mentor insisted that I should include repair/reassembly tools in my assembly designs. Sometimes people design for repair sometimes not.
Merry Christmas Ivan, Looks like you had a busy summer with the Audi.
It seemed like it would never leave the shop! Was definitely a challenge to find time to chip away at it while busy with other "regular" cars :)
Thinking about it for a bit now I believe the only way to insure there will no longer be problems with the fuel tank would be to replace it. Probably unobtainium. God luck sir. Looking forward to see what you come up with.
Thanks
Blower wheels rotate so the vanes “cut” the air like a salad shredder blade. Even though it looks like the air would be deflected inward toward the center of the wheel, instead it’s flung “forward” and follows the curved blower housing around and out the discharge. It will work a little if you reverse the wheel so the vanes don’t cut the air as it rotates, but output is about 1/3 to 1/2 of normal.
A washer in the new fan motor, how unlucky is that, but you fished it out :-D
I expected the wash/wiper motor to be stone dead.
Hopefully the mileometer and fuel gauge will behave. Perhaps the road vibration will keep them moving.
Amazing car! Weird car! Not sure what to say. My brother had about a 1982 Audi 5000 here in Canada. At the time, an inline 5 cyl was not common. The average garage would open the hood, look at that 5 cyl, and close it up and say go somewhere else.
After you get this to 100% it will still be a car I would never want to own or drive. I wonder how much a foreign car shop or dealer would charge for all these repairs. Several thousand for sure.
The epic saga continues.....
Best part of the audi job is your growing familiarity with the vehicle. He won't be able to go to anyone else!
Last time I saw a MAP sensor in the engine computer was the mid-70s Cadillac analog multi-port fuel injection. Used through 1979 in the Seville.
He's got to be approaching 5 grand on diag not to mention the parts. He's definitely spent more than car worth he must love this thing!
The Audi is a large part of my morning routine now. What will I do when its over? Ho HO HO. Merry Christmas Ivan
2023 isn't over yet... New Year's Special to come soon after the Audi :)
Ivan, you should know by now, nothing spins freely on this car, it spins expensively! ;)
I'm sure if you weren't getting RUclips clicks you'd have pushed this car off a cliff... Alternately, this car will likely qualify as a future donor car.
You have incredible persistence and patience
Beware of those rear calipers..When they start to fail/seize they can drag on the disc/overheat and boil the fluid. Ask me how I know. Great work.
Why would anyone want to go through this trouble to fix this junk car? Why would you want to go through all the hassle to do it? There is no way that you can charge the customer for your time. For RUclips videos? You have more patience than anyone I have ever seen. You must enjoy the challenge of problem solving. I own two wonderful Toyota hybrid vehicles that are 6 and 11 years old. They look and run like new but if I have undiagnosed problems, I am coming to your shop! I greatly admire your persistence and patience!
It was a wonderful learning opportunity with a very satisfying product in the end! Customer happily paid for every hour of labor. I certainly would never put this much time or effort into restoring a boring hybrid though 😜
@@PineHollowAutoDiagnostics I’m a retired teacher so I completely understand the value of the learning opportunity. I have owned many vehicles in my life but the three Toyota hybrids have been the most reliable and satisfying vehicles to maintain and drive. And of course, they get wonderful mileage. The multiple engines complement each other to reduce maintenance. I have never done anything but routine maintenance. I have never had to replace the brakes or the hybrid battery. I am very happy with the reliability, economy and performance. There must be a lot of people like me because it’s very difficult to purchase them, new or used. My dealer begs to buy the 2018 RAV4 hybrid limited at least once a week. Not happening!
@@rogerrocco5211 hard to beat a Toyota in the maintenance and reliability department for sure! However they are on the opposite side of the "fun to drive scale"... as most "appliance" cars are nowadays haha
You will enjoy the New Years Special after we get done with the German Spaceship 😉
@@PineHollowAutoDiagnostics It’s a joy to drive! Unless you own one, it’s impossible to know the potential for power. When I merge onto an expressway, all the motors engage and it takes off like rocket. But most hybrid owners drive conservatively to get better mileage. And there’s another element of pleasure. Non hybrid drivers hate to be around us and pass at every opportunity. We love pissing them off! Actually, I drive with the flow of traffic but it’s enough for them to see Prius to be annoyed. Love it!
@@rogerrocco5211 haha I've driven a Tesla...it was like a rollercoaster: fun for 5 minutes and then kind of whatever. There is much more that driving enthusiasts appreciate...the "feel and engagement" vs just acceleration and speed :)
Some old school standalone ecu's have vacuum lines plumbed directly into it for boost reference.
I admit many features from that car are just insane. For example those ufo brake disks! Never seen or heard about that but I've seen vacuum line in the PCM. I have it on FSO Polonez with 1.4L english engine supplied by Rover company. So I belive that all Rovers from 90s had that feature😊 It just had MAP sensor bulit in it.
SEEMS THIS IS A CHRISTMAS 2027 MARATHON
VW TDI's (1998 AHU) had a boost pressure line going into ECU.
Fuel tank clean proposition. Drain, remove pump for access. partially fill with soapy water and then try to brush inside somehow. Shop vac to remove soapy water, then rinse just water, shop vac. Clean rag then compressed air to dry. Just a suggestion. Obviously a new tank new tank would be best. Thanks for the videos!
You probably already finished the tank... I work on some old atvs and snow machines that always seem to have water condensed in the tanks. I clean them with a cheap electric fuel pump and a WIF filter - pull off the bottom and dump the output right in the tank.
Hi Ivan, i had a friend with the same tank problem because of the rust and he bought tank kit based on fibre glass, it coating inside and glueing all the rust.
I wonder how high the customer's tab is now running... And you still have problems to solve. Expensive Christmas special, Ivan :-)
Wait a minute, I'm just starting to watch this series for the first time now in Part 8....should I just take this as a public service announcement as to why you shouldn't buy an Audi and just skip the first 7 videos? Lol, just kidding....love your channel Ivan!
I love the sound of the Audi 5cyl. engines. I was wondering how you were going to tackle that blower motor. Replacing blower motors and heater cores gave me calluses on my knees pulling those blower boxes. Not fun! I was glad you could cheat it out.
That is the boost pressure sensor pipe going into the computer. I made a potential divider on the output of said sensor to increase the boost pressure on my 200T, it went like you know what !!!!
The chap who assembled the new blower motor was POSITIVE he'd put that thrust washer on before he went for lunch. Back from lunch and he can't find it anywhere.
A lot of early VW TDi BOSCH ECUs up to ~'98 (MSA ECU, eg: 1Z engine code) had built in MAP sensors.
I have seen the vacuum line on a 1996 Peugeot 405 Mi16.
Good morning Ivan from Nebraska
Very first Audi I ever worked on was a 4000s VERY similar. (My buddy was/is an Audi junkie, but he moved to Hawaii)
