Here we go again...another dead Euro on the road.
This 2009 Audi Q7 V8 has been acting up...losing power and stalling out. Finally it quit completely and the owner had it towed to his house.
A few other shops took a "stab" at it...literally.
When I get there the battery is at 3.8V...completely spanked. This one is going to be fun!

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.

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.

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.

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.

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 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...!)

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.

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...

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.

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..

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.?

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...

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.

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.
