If Ivan hadn't had to spend 2 hours trying to figure out what the other "experts" had done before him he probably would have fixed this on the first try.

I was in the service business for 45 years. The hardest part was dealing with intermittent problems and the customer.

As Eric at Advance Auto Diagnostics would say "This car is like an onion, it has layers of problems." I would unload it like a hot potato.

The amp power wire in the door jam is horrid

The more stuff hanging from a rear view mirror I see , my hourly rate doubles .

I had a feeling this one would come back. I hate going behind people who tried to do their own fixing. To many hands in it.

Great diag (all 3). I personally suspected the Playboy logo was the cause..

This hose is important for the mechnical "Fuel regulator"(build in the pump) to work correctly. When pressure in the lines after the pump drops , the regulator "closes" and allows to build more pressure forward of the pump. When pressure builds again and stabilize(forward of the pump) , it bleeds the excess from this hose . PS : The most important thing on GDI engine is engine timing. The high pressure solenoid opening/closing must be done at very precise time when camshaft lobe that drives the High pressure pump starts touching the follower of the HP pump. This allows pressure to build in high pressure fuel rail, or to be bleeded back to the tank. When cam timing is off , the camshaft lobe pushing/releasing action on HP fuel pump follower won't be synchronized with the opening/closing action the High pressure solenoid. Pressure would be out of spec - either too low or in some cases - higher. That's why engine timing is critical for GDI engine to work good.

Excellent detective work! I'll bet that MANY would never have found the existing, but horrible fuel pressure problem.

Nice find Ivan! I hate when the problem goes away and right after we’re done it comes back and leaves us explaining to the customer why we couldn’t find it the first time. 🤦🏽‍♂️ Cool customer for the fact that he understood where you were coming from..

Volkswagen GDI has normally open solenoid on High press pump if you disconnect sol at High pressure pump it should run on low pressure idle only Phonomal video Thanks Ivan

Too fast, too furious!

Have to credit Ivan for his tenacity, I would have declined the job just by looking at the car ! Disclaimer: I am not a mechanic ,I just play one in my head 🤣

That blue wire through the door gasket (or how it is called) is priceless.

I owned a Volkswagen Jetta. The engine was anemic and noisy, but reliable. The rest of the automobile was junk. The electrical system was a constant problem. Every window regulator on the car had to be replaced. This included the passenger side rear window that was used probably five times. Window seals started leaking at about 40,000 miles. There were so many other problems, listing them would be a short story. The dealer was a nightmare to work with. Because of the daily aggravation of just owning the vehicle, you couldn't pay me enough money to put up with ANY product associated with VW.

Great work again, Ivan. 👍 Once again you uncovered a suspicious spot that indicates that someone was sabotaging the fuel pump. Possibly tried to remove it earlier and tore off the lower assembly. 🤔

The amplifier power cable at 1:30 made me cringe... That's a fire waiting to happen.

Wow man. Another tricky diagnosis and General Ivan didn’t even have to position the parts cannon to be fired. Impressive as always.

I love that after all the diagnostic equipment is used (which you are the master) the old fashion pressure and flow are the deciding reasons to intricately examine the pump. Not considering GDI 90 psi sounds high when I am used to 50 in my old 2002. I always come away with some learning by these videos. Thanks.

Great repair - no parts required. I thought the data pid for fuel pressure showed it to be ok, tho. Goes to show you that sometimes old school methods are required.

Awesome! I wonder if the pump had been like that the whole time and the car was just barely starting... Doesn't that fat tube go to the pressure regulator? (In the pump cage)... Common thing people mod... Perfect example of why i'll never pay any good money for a modded car, way too many hidden "rookie" issues.

my ex-landlord's stepson had a Volkswagon Jetta that kept dying. found out there was an accumulator and pump assembly that was broken and very expensive he went to the wrecking yard and bought a used one and had it installed the kid went out and hot-rodded it and blew up the engine by running it out of oil.

Thanks for sharing Ivan. Nice troubleshooting. Stay safe and well Artie 👍

When i get a car like that i charge for the initial diagnosis that was a self induced problem. I would also charge additional time for chasing an intermittent problem. Most customers don't understand why it cost more for intermittent problems. If i spend multiple hours trying duplicate problem i should be paid. I had a car dealer bring a vw van intermittent no start spent my hour on it no problem. Call to get more time and they want me to drive it on my personal time to lunch or whatever. They picked the van up and paid an hour.

I had this same issue on a Ram truck. The tube ends weren't crimped enough to hold together. I reassembled it and better crimped the tubes and all was well.

Just like the other parts, the fuse, the pump power connector...someone messed with the fuel pump below deck. It's amazing how quick this could have gone had someone told you they were inside the tank, moved fuses and unplugged the fuel pump on your first visit. That transmission sounds like its been altered to shift like a tow haul mode !

The sign hanging on the rearview mirror says it all. Somone has been tampering the fuelpump. BS.mechanic . next will be the DSG gearbox.

Ivan, you are the man.

Nice work as always Ivan! Have a great day! (rumor has it that it ''Might" not rain today)

Great job 👍 Ivan !!! I just had the exact car in my shop for no ac.. compressor valve was not opening or getting 12volts . If I supply it with power it would work 💯% the cooling fans would come on Ice cold ac . I couldn't leave it like that lol 😆 I found a bad wire on the drivers side under the air box in the harness . . I hate those cars .

I love your turn of phrase . Brilliant

I love those quick DSG shifts!

Great diag, love the fix, NPN

You dedication to successful outcome is unbelievable. I have a mk5 5spd brm jetta with 395k original miles on it. I still have orginal muffler. Lol and get 46mpg in city. I love to see your various tests.

Love the shotty wiring in that car. Oh and that's really unfortunate your tool looses com on cranking.

Another "no parts required" fix. knarley toes at 17:33! Thanks for making eurotrash videos.

That was awesome. Thanks Ivan!

Hope you've charged every minute, that thing has been messed with , you didnt 3B it, eg you didn't buy, build or break it.

my 2012 had similar issue, but there was a recall, changed the HP pump and the rear seat fuel model to rev K. Hasn't done it since. Would randomly leave me stuck.

I new that there was Casper the friendly ghost 👻 on it, making you chassing him, no pump assembly disconnects that easily, it's been messed with from the beginning

Well played for the persistence great fix 👏👏👏🍺🍺🍺🍺

Ca-ching ring him up! he wants to mess with stuff he doesn't understand then he can pay for you to put it right, nice job

What about the missing 30A fuse from the last video. That car has DSG

Is the high pressure rail pressure sensor analog? If so perhaps you could scope it directly during crank to get around the data dropout :)

Nice diag had to sort through the built in problems, To help rule out a high pressure pump problem I believe all GDI engines can start and run (not well) on low side pressure

Someone doesn’t take the time to do that aftermarket wiring correctly. Looks pretty bad. I took pride in installing my amplifiers and various accessories back in the day.

If you select D immediately after start, the engine should try to restart if it shuts off unexpectedly. As long as you're in R or D/S it should keep the engine running or try cranking it - at least once.

Hi Ivan when you want to check any data pids from the diagnostic tool you can cycle the key on off but just before cranking the engine set up the diagnostic tool to what you want to see and then crank the engine the data Will show just don’t cycle the key it won’t work right and the solenoid on the high pressure fuel pump can be actuated with the scan tool. And maybe the reason the ecu didn’t show any low fuel pressure faults is probably that if this engine is tuned then the threshold might be higher than a stock tune . Good job considering the car was almost sabotage beforehand.

Who the heck molests a Passat like that?! That's a case study all right. Case study on poor taste.

Great vids Ivan Part 1 & 2. Volkswagons like Chryslers ;-) NPR again... You've been on a roll lately.

Looking forward to Part 3

I think most of us would of thrown a new pump at it. Great job putting it back together.

The crap hanging from the rear view mirror adds at least 100 hp.............LOL

almost same problem i had . suddenly did not want to start. after changing almost all parts in the fuel system they found a loose wirre in a fuse box so fuel pump dident get power

Hi mate, thanks for video.

Nice job as always

Part 2, Ivan is here...To pump you up!!!

Great video Ivan. I hope this doesn’t come across as rude but I’m just wondering if that pipe coming off the pump was the cause, how does it intermittently fail? Could it just be chance that the pump started to work again?

17:30 THAT TOE NAIL!!!!!!!!!!!!!!!!!!!!!

Good workSteve

Hi great video👍, I notice the warning lamp light was off after fixing the gas pump, did you replace a bad bulb light or it was the pump?.

Some vehicles we can look at it know we should just say, “uhhhh, no can’t fix this one, sorry.” But something stops good people from doing it, so we only wish we had instead.

great talisman dangling from rear-view--bouncing spider and antisocial sign. better than X-Band

Yeah,that's what u have to do with all of these direct injection cars,I check fuel pressure from both pumps,most of the time the high pressure pump leak fuel back into the oil and they diesel and have run on..

I have had multiple similar issues with those CHEAP-ass plastic aftermarket fuel pump "assemblies". The OEM ones are better, but still VERY cheap design obviously.

You’re killing the parts industry!

Ivan, What a head scratch-er.. that was.. was a hose clamp missing from that disconnected hose??

Lowered cars have a lowered life expectancy. I have 270K on a 2.5 Jetta with a 09g auto. 2006 Only new car I ever bought. all stock still. Great video. Scott

The car losing com every time you start it is frustratingly stupid. It's also a bad design with the Thinktool, that you have to completely reset-up your data PIDs every time communication is lost. Surely it would be more sensible to have a "retry" button where it just goes back to the data streams before com was lost

Good job 👍

Do you think someone has had the tank sender out and not fitted it correctly ?. Maybe drawing air at the feed hose. Nice video.

Good job

Hey Ivan. In my experience, most of the DI cars that I have had to troubleshoot will start and idle on the low pressure pump. They will not have enough power to drive around though.

I came across something like this on a 90's Jeep Grand Cherokee that had been in a fairly significant collision and subsequently, fixed. Not too long after the bodywork was done, the owner noticed issues with power in the mountains, and random loss of power/stalling when the tank got low. The only thing I could figure was the impact was hard enough to break the fuel pump assembly. In my case, the pump assembly couldn't be assembled - I had to replace the entire unit. Problem solved! It worked long enough for the owner to sell the Jeep and buy a brand new replacement. He didn't think it would ever be the same post-collision...and I would have to agree.

If Ivan has diagnosed and repaired it, I would keep it! Because the next one he buys (assuming second hand) Ivan will not have looked at it!

Kudo's Ivan. Young man I need my standard 5 speed Trans rebuilt. When you coming down to Old Hickory, TN? I sure could use your help. Good video.

Nice to see that you obey stop signs.

@Pine Hollow Auto Diagnostics, I was thinking of buying one of these CC's. What do you think about them?

Watching you doing the troubleshooting was fun but at soon you took the pump out I got suspicious uhmmm... someone was there before. It was sabotage who ever look it didn't know how to put it back together correctly customers are dishonest that's not cool. Great video thanks

Another great video.

You couldn't drive that car 10 miles where I live without getting ticketed for drivers view obstructed.

Nothing like a few curve balls thrown at ya. Good fix

Dang, Ivan, you Are good.

Why did that hose come loose? That was the problem? Was it some how locked or tightened in position? What about a TSB regarding that hose? Or upgrade?

Why did that hose slip out? I think a clip or something is missing from that black tube.

have to wonder if someone messed with that also

Nice!

I’ve had a few Audi’s (VW) always had electrical problems, never again..

Can you rig a setup at the DLC so when you crank the engine you don't lose power to the scan tool IF that is what is happening? I may have monitored the fuel pump from the beginning as access was there luckily, with either a voltage drop test or an amp clamp on the scope to see what the pump RPMs were (both of these tests) running and priming and not starting, the problem should show up with this information.

So the pump draws more current when there is more head pressure?

For any chance of selling it I'd remove all those body stickers. A simple problem made into a difficult one from someone else messing with it. I'm sure you told the owner if the pump faults again , change it .that why they don't call you out again for the same problem

i knew the car would come back because the duty cycle for the Vw should never be over 55% at idle. in the last video I saw way over that

how the hell did that long black pipe come out all that way i seen them brake off but never all the way out like that think some one was messing with it before and not put back the right way?

Dude, what ever happened to the high mileage prism/Corolla that you did the pistons rings on?

I've never owned a pair of sandals. Can't imagine working in sandals or shorts.

Mmmmm makes you wonder why that pump was disconnected, maybe swapped with the other vw? Check filter too

I wonder how that hose got loose in the first place?

Too many car ornaments is the issue...right, back to the video ;)

I assume the guy who unplugged it took the pump out and had no more clue on reassembling the pump than I would have. The pump looks, cheap, complex, with planned obsolescence plumbing, what's wrong with a plastic box that pumps fuel.

I had the same frustrating issue with a petrol Citroen years ago. That was less than a year old. Dealer gave up after putting the parts cannon into overdrive. The low pressure fuel pump just died when it got warm, usually after around 30 mins. European strikes again 😁 Nice work on persisting with this, was that a Rav 4 you turned up in 👍🏻
