I had never heard of triple square until I was working on a VW and my torx bits didn't work. Why would they use such a bizarre bit when the rest of the world uses torx?
@@mariosaccoccio1688 lol. The same german engineering that makes changing the rear brakes and rotors on a GTI a 2 hours job instead of a 15 minute job like every other car.
On my 2005 Audi A6 3.2L I had a no start. I applied power directly to pump leads, and pump did not run. Replaced fuel pump and it ran fine for 3 weeks. Then no start again. I apply power direct to pump, and pump worked. Then began hunt for the fuel pump control module. Different manuals suggested different locations. Turns out it was located directly above fuel tank lock ring jammy, off to the side, under seat sheet metal. Manual suggested lifting car, unbolting exhaust, lowering tank... That aint happenin. I used a tire spoon and messaged sheet metal up, knock out plastic bracket, and swapped in a new-used module. I retained it with a bolt and nut. Massaged metal back into shape. Ran perfect for 2 more years (then timing chain issue). I love Audis but they are not friendly to work on. Not at all. But I love them. :/ I thought a failing pump may have weakened the module? My new pump was OEM Valeo.
The battery location is pretty bad. The first thing that I would change the first time the battery was replaced , would be those seat bolts with conventional hex heads.
@@briantii eh not a huge factor, but keeping it away from the engine heat does help. Key is that it is huge, so never gets too depleted by parasitic draws.
@@PineHollowAutoDiagnostics Heh true. I can say the golf cart battery in the back of my bmw is abt 7 years old and still going strong. The battery in my Lexus located right above the exhaust manifold was like clockwork when I was daily driving it… every 2.5 years and it was cooked. Keep up the awesome videos. Really enjoy them!
Battery under the seat is to help with ejection. In the event of a crash, the exploding battery launches driver out of harms way. German ejection seat.
My 2001 lesabre has the battery under the back seat, easy to access just pull the back seat up, all the electrodigicals are there also., the battery lasts forever also, mine is 6 years old and has no issues, in winter it starts right up, it does require a special battery though, it needs to be vented to the outside, there's a tube that goes out the bottom of the car and two connections on the battery itself.
Your analysis is spot on I've seen a bad fuel pump blowing 10 amp fuse every once in a while for no reason except for worn brush contacts. Arcing/amp spikes is the killer of the digital pump driver
I think you’re correct. In my comment, I was thinking maybe the module would have been ok with a new fuel pump. But I think your point is correct. The module was toast, from the reasons u stated. I bet that was about a billion for the module and fuel pump
I work on mostly euro cars and one thing I learned is the modules are failure prone and I routinely change the pump as well because it always seems to die soon after
Hey Ivan don't stress it too much I always recommend both parts . I got burned on that issue already. I either do both or let the customer take his chance .
I have done this repair and pump was sticking . I wish I had scoped the driver, the car did run on by-pass but would fault again after standing all night.😁 look forward to your vids top man.
I have two older vehicles that use those electric inside the fuel tank fuel pumps. One vehicle, a GMC, is on its 4th fuel pump. The other vehicle is on its second one. We used an airtex brand in one repair in 2009 and that part lasted the least. Replaced the airtex with a GM part, it lasted a few years then quit in 2012 as it was weak pressures. Replace that one with a Delphi 5 years ago and it still working. The other car, a 2001 Lincoln LS8 lost its OEM pump 4 years ago. Replaced it with a Delphi brand and its still working. In both cases, we replaced only the pump itself as they were available separately which saved us hundreds of dollars in not buying the entire fuel module assembly. All of my older vehicles from the 1960's and 1970's never had a fuel pump failure and they were all "mechanical" which have more moving parts than today's crap.
Modern vehicles. I am retired and enjoyed helping my grandson keep his first vehicle, a twenty year old truck, going, I bought a 28 year old truck to play with. After rebuilding the engine and doing a lot of minor repairs on the body, interior, doors etc., the thing has been running so dependably I find myself driving it everywhere. I agree with another commenter here that said he decided a vehicle was a device to get him from point A to B. Have we really improved vehicles in the last 30 years as far as bells and whistles go? Also Ivan, I watch for your new videos. A great channel.
Hello Ivan, usually when I get a bad low fuel pressure module I change both module and pump on vw audi, saves later aggravation, but when it's the pump I do not change the module. great work
Fascinated by your road trips Ivan. Hope some day you get to wilkes barre and more specifically Forty Fort, by boyhood home. Oh yes, Audi cars all require mental health exams for buyers and fixers.
Superb roadside diagnosis. Those triple square heads are all over most Audi's, I had to buy a set for one little job and never used them since. I feel for the owner, that German tank will declare war on his bank account 😁
I would usually replace these as a pair. I tried this with the VW HID head lamps, just by replacing the lamps. Then the ballast would go bad, then the terminator plug went bad. Just replace the entire thing. Now I have over current issues with the factory wiring because they were designed to run 10,000 different lighting styles from one factory harness.
Your patience is just amazing Ivan👍..I totally enjoy watching your diagnostic approach to car fault analysis..I even bought a cheap scanner to investigate my early model Hyundai i30 diesel recent Check Engine light …DTC report, powers and grounds , visual inspection .cool as 👍😎
You are correct Ivan, as the pumps begin to fail there is always an erratic current draw with increasing amperage consumption. It usually starts small and over time ramps up to some insane levels. I've seen pumps taking as much as 20 amps before they finally expired, this condition obviously kills the control units circuitry. A timed run test on the pump to check its amperage consumption is a sure way to confirm the state of health of an older pump.
I've seen that happen with Ford trucks and vans. The fuel pump goes bad, other electrical parts of the pump's system start going bad......later on. Good fix Ivan!
Ivan, I have to give you credit for even looking at fixing these foreign cars, they are a nightmare getting at critical parts, like a battery. Great videos, thanks.
Wow, two parts failing same time? That is unheard-of!! Almost never! But wow, fuel pump overloaded the module and killed it. That's my bet. Great video of the diagnosis!
@@adotintheshark4848 modern cars have ran great for many decades with just a fuel pump and relay,., the module is just a problem waiting to happen with no real benefit for safety , reliability or economy.., its big tech taking over your transportation and trying to force u to a stealership..

The sole intent is to discourage the home mechanic. Look at the rear brake pads. U can’t do it at home without the special tool to wind back the electric emergency brake. U can’t take the battery out without that special socket. And don’t EVER just push back the caliper pistons on a Mercedes. It will put the ABS module in a funk that u have to get a dealer tech to fix. Workaround, visegrip the rubber brake hose, and open the bleeder.
I always open the bleeder nipple on a caliper when pushing the pistons in on a pad replacement. I've had some lovely experiences with caliper crud going back up into the ABS modulator unit that then caused it to bind up the brake system like you cant believe.
👍, Had something like that on Volvo, fullfielding the pump directly ans calling a fuel pump module. A customer ordered a module from e-bay "dorman" .After replasement of a module car still didnt start.We ordered used module and the car fired up and was running for good 10 minutes aftwr road test.When the custo.er came to pich up the car IT DIDNT START😡. When I redid the testing the pump was dead.Luckly the cuztomer understood the situation. Your diagnosticwas good as yusualy Ivan👍
With all of that computerization, all of the tests, all of the modules, the car still didn't know it had a pooched fuel module, and a fuel pump drawing too much current.
Sadly the control side of the pump fuel pump module does not know crap. It also keeps its condition and its close buddy the fuel pumps condition, in a secret relationship from the rest of the cars systems. I know,,,, you would think there should be some form of monitoring in relation to voltage and amperage. This just goes to show that all the equipment you really need for this module and pump test a multimeter and test light.
Also there was a recall on many VAG fuel pump modules of this era. Not sure if it extends to 09 though. They were randomly leaving people stranded. Would have been good to also check the recalls. Would have given good direction as well.
Why we referred to the emblem on the grille as "the four rings of financial ruin". I worked for a Porsche Audi dealer and Audi owners always leased their cars. After the lease was up they would lease another. Audi had a great deal. Parts and service were included in the lease. We rarely ever saw customer pay work. The people who came to the parts counter with older Audis were always complaining about the expense of the parts. We sold a lot of the mineral oil for the central hydraulic system (hydro assist and power steering) as they leaked like sieves.
The Audi, Hidden Compartments Maze Game.... I think the fuel pump was on the way out and took out the module. The second replacement module brought the car back to life, but the weakening fuel pump started acting up again. Being as the diagnosis was already previously targeted, the culprit fuel pump was replaced. I can imagine that whole fix was not cheap...
Great diag and repair Ivan 👍 makes me panic a bit knowing I have an Audi here 😁😁 had it 3 yrs no problems yet touch wood !!!! Hope if I have any problems I can find an Ivan or Eric equivalent here in Scotland 😀😀👍
In my 35 years of working on car’s I would charge twice the labor rate for working on all Euro Car’s or SUV’s because they are always extremely difficult and Taxing on My Brain.

IVAN, ANOTHER PERFECT STUDY CASE ALL THE WAY VERY ATMOST PROFESSIONALIZM AND VERY HELPFUL TO ALL OF US IN THE AUTOMOTIVE FIELD. THANK FOR YOUR DEVOTION TO ALL OF US FOR A GREAT HELPFUL SUBJECT MANNER. YOU ARE AMAZING.
I have 2014 Hyundai Sonata I’m have a problem with hard shift from 3rd to 4th gear. It Daley shifting to fourth gear. The rpm go up to 4 car makes noise then kicks and car jump. The funny thing there is no code at all. I used autel maxsis pro and thinktool the one you have.
Buick puts some of them under the back seat. Silly, but a lot easier to access than this case. Makes me wonder how long before someone thinks that hiding them between the firewall and the dashboard would be a great idea.
I'm so glad I found your channel. Maybe sometime give suggestions on what diag tools that can be effective for someone not earning a living doing this. I fear all are too expensive. And, I fear finding someone near me with your skills and knowledge.
I'm a DYI mechanic. Over the years I've invested in code readers. Finally spent 800.00 on a scanner. I can see and do lots of things. Learning from Ivan and others. My next purchase would be the Pico scope but that is out of reach now. Busy with other items. I'm not a serious mechanic but I love being a mechanic and do enjoy working on vehicles.
I directly thought this would have to do with the fuel pump relay module on top of the pump/sender unit if it a gas car. Those cause a plethora of problems when they go bad.
I had a simular problem on a golf and I got the module at the scrapper $10. That one was stuck close so the fuel pump never shut off unless you pulled the fuse. The new module fixed all the codes (every can bus module) except the classic abs pump code (pressure transducer open o short to ground) also that car had an intermittent nox sensor code that I suspect was due to a stretched timing chain.
only 8minutes in. I have to comment before seeing what's happening. what you are seeing with the battery isn't showing the battery is bad. this is an AUDI. I've gone through this same annoyance. the voltage regulator module is causing this. the ONLY way to diagnose a battery in a Q7 is to lift the seat and bypass the voltage regulator module. you must also go in and clear the module telling it its a new battery after all this or the module will go ballistic causing random other modules to fault. its a real nightmare when you dont know this. a shop tried to replace my battery telling me they couldnt charge it exactly like you are seeing. only prob was I knew for a fact my battery was brand new and took the car back to resolve it myself. it really sucks the battery is under the front seat making the default to assume using the terminals under the hood are actually useful LOL..
I had a friend who liked to buy used Audis. They looked nice but he Always had problems with them running reliably. My advice is to avoid these like the plague.
Sadly, that's just the part of a long list of trouble this car will be giving it's owner. I owned a series of Mercedes' in the 80s and early 90s and they were lovely cars that had some quirks, but never failed to run and were mechanically amazing. The Germans lost the plot in the late 90s when they decided they would take on Lexus by adding gadgets and gizmos and complexity became the objective. That said, without the Germans and Hyundai we'd have far fewer interesting videos from Ivan! So, yay to dubious engineering? (as long as it's not your own car...!)
It is a shame how far gone the Germans are with cars. They can sure can design them to look amazing but I can’t put myself forward to own another one ever again knowing how unreliable they are typically becoming.
I still daily drive an 84 and 91 Mercedes and a 2000 Camry . All reliable and waaaay simple compared to the new stuff. I have worked on cars since the 70's.
Another Uber Disaster Incredible. These cars are throwaways. There are lots full of them where I live. Ivan you did a great job. Whoever put these bolts on and the battery under the seat does not want anyone fixing their cars but them. I say they can keep them. If you gave me one free, I would drive it to the first dealer and use it as collateral to buy a Toyota, Honda or such.
If you can’t afford a luxury car when it was new don’t buy it when it is used. You have to keep up on your maintenance. I hear people say Audis are problem cars, but I have a 2017 s3 and all I change is the oil, and it has been my daily ever since.
on the audi Q7 the alternator has a connector in the back of it which is loose, would that cause any issue with current going or getting to where it should be to start ? If not then i believe i may have a bad fuel pump and/or module as you diagnosed here .
It's seems any audi/vw with a 4.2l attached to it has fuel pump issues. Can't say I've seen a bad fuel pump module on them. Maybe the pump was too weak an couldnt flow enough fuel at a commanded 10%-20% duty cycle, to keep engine running.?
Ohhh this brings back memories. I'll be praying for this man as this is just the beginning. These damn money pits need triple square. I had the exact issue with my Q5 but mine was worse. ECU and wiring got corroded cause the designers put the thing right bellow the windshield. Brilliant vehicles to own and work on (sarcasm)
I need those wiring diagrams badly! LOL... my Q7 has water damage from the pathetic drains clogging and I need to track down where the faults R lol. so annoying. if I disconnect the battery it clears the fault and radio works until next key on. which I would be cool with... except battery is under the driver seat lol! so anyway this being a 2009 that owner better fix the rear right roof drain ASAP as that is 2 years past 100% going to leak onto the bose amp and all the other modules below the drain...
@@markstevens1729 Hmmm, that's surprising. I once owned one of the 2014 Passat TDIs and it was a very good car for me. The buyback was too generous for me to pass up and I knew that VWs are expensive to maintain. Nevertheless, I thought it was well made and performed beautifully in the years I had it.
All those fancy electronics in that car and the fuel module can't tell that it's being overloaded.. smh. A simple breaker built into the module or even a fuse built into the line between the module and the pump would have saved two dying modules. At the very least, it should have tripped a code for high current draw. SOMETHING> lol... So that module is not very smart-- it's just a fancy relay really; that turns on and off at the duty cycle that the computer tells it to. So it should be fairly cheap to make-- but something tells me that it wasn't cheap to buy.
Audi is a company. The only job of a company is to make a profit. If they can sell a car and sell fuel pumps and modules for that car, that’s a double profit for the company.
@@peto22 I get that--- we just have to learn their philosophy on how they build things, and vote with our wallets accordingly. Audi is known for being focused on horsepower, but they're quality and repairability is horrible. Meanwhile, Toyota is usually tame with HP, but they are super focused on quality and easily to replace and repair parts. We just gotta pay attention to these details.
I bet Audi parts are pricey. Probably the pump being crap took out the module. It seems bizarre though that the fuse protecting the circuits didn't fail. Must have been on the verge of doing so.
@@PineHollowAutoDiagnostics Perhaps, but I've usually seen that kind of rust when people have leak issues in the cabin. My first thought when I saw those bolts is "....flood car...", but obviously not.
So he replaced the module, and then the pump. Did the new module cook the pump? What parts did he use? OE or aftermarket? I have a feel there might something else. Anyways, good diag on your part.

Advice; if you ever come out to work on Audi/VW/Porsche, you should being a set of triple square sockets. Used all over the car.
Triple square.. This is the first I've seen that term. lol.. cool
That is just the shape of the socket - three squares on top of each other.

Another great diagnosis, Ivan. However, what a fantastic design when one has to remove the front seat to change/check the battery.
On the other hand, I liked the accessibility of the fuel pump. I had a Ford Transit with the battery under the front seat, it was a pain to change.
Battery under the seat is to help with ejection. In the event of a crash, the exploding battery launches driver out of harms way. German ejection seat.
Some GM's had the batteries under the window washer fluid tank, that was fun!
They want to bring the battery towards the rear to help weight distribution

It’s actually a pretty good place to put them. Inside the car batteries tend to last a really long time.
That's nothing new for German cars. My 66 Bug had a 6 volt battery under the rear passenger side seat.
Under the hood, atmospheric dirt builds up on the battery, then wet weather gets into dirt, and you have a constant drain on the battery.

You cannot let the battery die in these cars. It stresses modules and set all kind of battery protection codes. Change the battery then troubleshoot.
For as hard as they made it to get the battery out it doesn't look to bad to do a fuel pump.
The Audi, Hidden Compartments Maze Game....
I think the fuel pump was on the way out and took out the module. The second replacement module brought the car back to life, but the weakening fuel pump started acting up again. Being as the diagnosis was already previously targeted, the culprit fuel pump was replaced.
I can imagine that whole fix was not cheap...
Great diag and repair Ivan 👍 makes me panic a bit knowing I have an Audi here 😁😁 had it 3 yrs no problems yet touch wood !!!! Hope if I have any problems I can find an Ivan or Eric equivalent here in Scotland 😀😀👍
In my 35 years of working on car’s I would charge twice the labor rate for working on all Euro Car’s or SUV’s because they are always extremely difficult and Taxing on My Brain. I like to call it you had to have this brand rate. And I know all too well how different these Vech’s can be born and raised in Ohio and come from a Ford Family and I own a 2000 Clk 430 and 2011 Land Rover…and you won’t find Triple Square sockets at local auto parts store…..Maybe Napa might have them but they can order them but you might as well get them off Amazon. 🤟🏻🇺🇸 Good Luck Ivan 🤟🏻🇺🇸
Oh wow they had them I will take that Bad on saying they won’t.
IVAN, AWESOME diagnoses and approach really appreciate the time and effort you put in ur videos million thanks brother. cheeeeeers
IVAN, ANOTHER PERFECT STUDY CASE ALL THE WAY VERY ATMOST PROFESSIONALIZM AND VERY HELPFUL TO ALL OF US IN THE AUTOMOTIVE FIELD. THANK FOR YOUR DEVOTION
TO ALL OF US FOR A GREAT HELPFUL SUBJECT MANNER. YOU ARE AMAZING.
Thank you for the kind words Sam 🙂
Ivan, you're the best! Nice work!
I have 2014 Hyundai Sonata I’m have a problem with hard shift from 3rd to 4th gear. It Daley shifting to fourth gear. The rpm go up to 4 car makes noise then kicks and car jump. The funny thing there is no code at all. I used autel maxsis pro and thinktool the one you have.
I thought Chrysler's idea of putting battery in the front fender well was stupid, but this Audi idea is moronic. SMH. Great video !
Buick puts some of them under the back seat. Silly, but a lot easier to access than this case. Makes me wonder how long before someone thinks that hiding them between the firewall and the dashboard would be a great idea.
Could the module be protecting itself from high amp draw of pump?
Your videos never disappoint Ivan, excellent as always!
Patience of a saint too.
I'm so glad I found your channel. Maybe sometime give suggestions on what diag tools that can be effective for someone not earning a living doing this. I fear all are too expensive. And, I fear finding someone near me with your skills and knowledge.
I'm a DYI mechanic. Over the years I've invested in code readers. Finally spent 800.00 on a scanner. I can see and do lots of things. Learning from Ivan and others. My next purchase would be the Pico scope but that is out of reach now. Busy with other items. I'm not a serious mechanic but I love being a mechanic and do enjoy working on vehicles.
@@2nickles647 Thanks for the input. This has been my fear. Expensive to get the minimum of "very useful" tools.
And yeah. Euro's are a pain. I work on them all the time. But they pay better. And once you've worked on enough of them they get easier.
I directly thought this would have to do with the fuel pump relay module on top of the pump/sender unit if it a gas car. Those cause a plethora of problems when they go bad.
I had a simular problem on a golf and I got the module at the scrapper $10. That one was stuck close so the fuel pump never shut off unless you pulled the fuse. The new module fixed all the codes (every can bus module) except the classic abs pump code (pressure transducer open o short to ground) also that car had an intermittent nox sensor code that I suspect was due to a stretched timing chain.
What an odd problem! Fun and educational to watch, with all the German quirks getting in between. Your videos never disappoint :-)
Outstanding video again Ivan! I love your work and I feel like i learn something new with every video you put out.
What audi really needed was a module that would protect their module.
a module modulator?
only 8minutes in. I have to comment before seeing what's happening. what you are seeing with the battery isn't showing the battery is bad. this is an AUDI. I've gone through this same annoyance. the voltage regulator module is causing this. the ONLY way to diagnose a battery in a Q7 is to lift the seat and bypass the voltage regulator module. you must also go in and clear the module telling it its a new battery after all this or the module will go ballistic causing random other modules to fault. its a real nightmare when you dont know this. a shop tried to replace my battery telling me they couldnt charge it exactly like you are seeing. only prob was I knew for a fact my battery was brand new and took the car back to resolve it myself. it really sucks the battery is under the front seat making the default to assume using the terminals under the hood are actually useful LOL..
That neighborhood looks like one of the residential areas in the UK.
Those Are triple square fasteners I believe. Lol I'm telling you like your gonna see it before you go to the store haha
these vag pump control modules usually go bad because of the pump itself, honestly haven't seen one where it had died on it's own
I had a friend who liked to buy used Audis. They looked nice but he Always had problems with them running reliably. My advice is to avoid these like the plague.
you work in Street to hard .you do great job . thank you..
Nice diag Ivan!
I bet the leather smelled really good when it was new.
12:11 first time i've heard him sigh in frustration
That special bolt is most likely a triple square design.
They are called "triple square"✌️
some brands one should just stay away from buying (or fixing)
Sadly, that's just the part of a long list of trouble this car will be giving it's owner. I owned a series of Mercedes' in the 80s and early 90s and they were lovely cars that had some quirks, but never failed to run and were mechanically amazing. The Germans lost the plot in the late 90s when they decided they would take on Lexus by adding gadgets and gizmos and complexity became the objective. That said, without the Germans and Hyundai we'd have far fewer interesting videos from Ivan! So, yay to dubious engineering? (as long as it's not your own car...!)
Let's not forget about the degrading wiring harness. Those are really fun.
Nicest car had was a 1989 Mercedes 300TE estate, nothing fancy, cloth seats even!. What a car-I still miss it.
Much of the same thing can be said for owning Cadillacs - something I also learned the hard way.
It is a shame how far gone the Germans are with cars. They can sure can design them to look amazing but I can’t put myself forward to own another one ever again knowing how unreliable they are typically becoming.
I still daily drive an 84 and 91 Mercedes and a 2000 Camry . All reliable and waaaay simple compared to the new stuff. I have worked on cars since the 70's.
Another Uber Disaster Incredible. These cars are throwaways. There are lots full of them where I live. Ivan you did a great job. Whoever put these bolts on and the battery under the seat does not want anyone fixing their cars but them. I say they can keep them. If you gave me one free, I would drive it to the first dealer and use it as collateral to buy a Toyota, Honda or such.
If you can’t afford a luxury car when it was new don’t buy it when it is used. You have to keep up on your maintenance. I hear people say Audis are problem cars, but I have a 2017 s3 and all I change is the oil, and it has been my daily ever since.
Good job! 👍
Those seat bolts are triple square bits.
on the audi Q7 the alternator has a connector in the back of it which is loose, would that cause any issue with current going or getting to where it should be to start ? If not then i believe i may have a bad fuel pump and/or module as you diagnosed here .
Great work
not sure why it crossed out the info i posted upon the kick down switch and the adaptation but thats what both said on my icarsoft tool
Great Channel! Ivan is the man!
It's seems any audi/vw with a 4.2l attached to it has fuel pump issues. Can't say I've seen a bad fuel pump module on them. Maybe the pump was too weak an couldnt flow enough fuel at a commanded 10%-20% duty cycle, to keep engine running.?
And this is just one more episode that reinforces my opinion that you could not GIVE me a car built by the Grrmans. Those guys are nuts.
Techs should always have an Audi or two to work on to toughen you up. They will push you to the limit of your patience and skills
triple squares is what those bolts are
After half hour cranking...you have new tour to change spendet crank motor.
What do you think about a 2002 Mercedes.clk 430 convertible
Ohhh this brings back memories. I'll be praying for this man as this is just the beginning. These damn money pits need triple square. I had the exact issue with my Q5 but mine was worse. ECU and wiring got corroded cause the designers put the thing right bellow the windshield. Brilliant vehicles to own and work on (sarcasm)
U live in a leafy area and bulk head got flooded due to blocked drain holes typical vag issue
AUDI :
A-nother
U-seless
D-device
I-nstalled 😂 , Great job 👌
I need those wiring diagrams badly! LOL... my Q7 has water damage from the pathetic drains clogging and I need to track down where the faults R lol. so annoying. if I disconnect the battery it clears the fault and radio works until next key on. which I would be cool with... except battery is under the driver seat lol! so anyway this being a 2009 that owner better fix the rear right roof drain ASAP as that is 2 years past 100% going to leak onto the bose amp and all the other modules below the drain...
Audi = nightmare. How do I know ? I owned one. Never again !
Great job Ivan. Just wondering if you think this car might have been flooded in the past. The rusty bolts under the carpet got me thinking 🤔
Nah, German cars all have an unfindable leak in the cabin that allows water to flow down to wet the mats and ultimately rust out the floor.
If they are like me they left the roof or windows open during a rain storm. Vent visors are a life saver in the midwest. Never again.
@@markstevens1729 Hmmm, that's surprising. I once owned one of the 2014 Passat TDIs and it was a very good car for me. The buyback was too generous for me to pass up and I knew that VWs are expensive to maintain. Nevertheless, I thought it was well made and performed beautifully in the years I had it.
The rusty bolt is quite typical. You carry loads of moisture and salt into the footwell with your shoes during winter time.
@@kain0m Maxspider 3D floormats fixed that problem as well.
All those fancy electronics in that car and the fuel module can't tell that it's being overloaded.. smh. A simple breaker built into the module or even a fuse built into the line between the module and the pump would have saved two dying modules. At the very least, it should have tripped a code for high current draw. SOMETHING> lol... So that module is not very smart-- it's just a fancy relay really; that turns on and off at the duty cycle that the computer tells it to. So it should be fairly cheap to make-- but something tells me that it wasn't cheap to buy.
Audi is a company. The only job of a company is to make a profit. If they can sell a car and sell fuel pumps and modules for that car, that’s a double profit for the company.
@@peto22 I get that--- we just have to learn their philosophy on how they build things, and vote with our wallets accordingly. Audi is known for being focused on horsepower, but they're quality and repairability is horrible. Meanwhile, Toyota is usually tame with HP, but they are super focused on quality and easily to replace and repair parts. We just gotta pay attention to these details.
I bet Audi parts are pricey. Probably the pump being crap took out the module. It seems bizarre though that the fuse protecting the circuits didn't fail. Must have been on the verge of doing so.
Yeah I should have thrown an amp clamp on the pump wires!
Oh, an Audi! Ivan's favorite!! :D
It's odd the floor bolts are rusted; was this car flooded in the past?
Probably salt on the carpet...
@@PineHollowAutoDiagnostics Perhaps, but I've usually seen that kind of rust when people have leak issues in the cabin.
My first thought when I saw those bolts is "....flood car...", but obviously not.
Those things will climb an Olympic ski jump as long as it starts haha!
Dantes circle of hell has nothing on Audis four circles of despair
So he replaced the module, and then the pump. Did the new module cook the pump? What parts did he use? OE or aftermarket? I have a feel there might something else. Anyways, good diag on your part.
Yo tengo una audi no prende será q m puede ayudar si activa las bombas pero no da encendido el arranque si se siente flojo necesto diagrama d coneccion d mangueras del tanque d combustible le agrafesco
