Ivan will drive out very early in the cold morning over a mountain to diagnose someone's car. Gives a new meaning to mobile mechanic. I could imagine him being a doctor years ago.

One thing i like about ivan is that he try's his hardest for the customer a rare thing these days

This is called tandem pump in my region, as it assists fuel and vacuum for break booster and solenoids. These engines in my experience last very long time, have very low fuel consumption and have reasonable power for the engine size. But there are no engines without problems. Greetings from Estonia! Ivan, good video as usual!

There is only one right way to set the timing correct on a PD TDI and that is adjusting the “Torsion Value”. Using VCDS or another scanner go into “01 Engine” and choose “Group 004” and adjust the “Torsion Value” to +- 2.5 ˚ KW (KW stands for Kurbelwelle ie Crankshaft), when the engine is hot… And that’s it…😊😊😊

This is not so much for you Ivan as for those who watch/appreciate your content. I’ve been watching Ivan diagnose for quite a while now. It dawned on me recently that I watch several providers that are top notch and almost NEVER like (👍) a video. I’m gonna challenge myself first and maybe some of you to turn a new leaf. Ivan deserves our support! Let’s all agree to develop a new HABIT. Let’s LIKE (👍) every video of IVANs for the entire month of FEBRUARY to show our support and encourage him to keep the faith! THE ENTIRE MONTH OF FEBRUARY!!! Leave a short comment too! Thanks Ivan. 🤠🇺🇸 Let’s “Make our Community(s) Great Again!!!” God, Country, Family, Friends and self. The Code.

I love those dirt roads over the mountain and out of happy valley. Lots of fun and gorgeous views from the top... (4x4 required, of course). Been a while since I have gone that way.

I just sold my 2003 Jetta TDI and I have to say I was very happy to get 316,000 miles out of it. I purchased it new and did all of the maintenance myself. One of the best cars I have ever owned cost per mile.

Good vid Ivan, have you ever watched DiagnoseDan ? He is really good at finding the problems other garages can't... his CAN BUS knowledge is second-to-none, very logical in his diagnosis of vehicles... He also seems to be the same type of guy as yourself, dedicated to looking after your customer & doing the job right !! 😎👍☘️🍺

That is the tandem pump, not the high pressure pump as it just make a little pressure which is fed to the injectors which are independent pumps actuated by the separate cams on the camshaft. Each injectors produces around 2000 bar when hit by the cam, then it is electrically actuated to inject fuel in the cylinder. This PD was actually invented in the US I think and is one of the most reliable injection technology for diesel, but it has it limits related to emissions ...

Thanks for posting the scenic drive through the mountains.

Thanks Ivan another great video for us to watch (Sunday)

I just put my tv on your channel and let it play all day in the shop! Always something new and interesting to learn on PHAD! 😊

Nice drive out to the customer 👍🏼 You’ll be doing 4x4 off-road videos soon 😀

Hi Ivan, Good call regarding the pump. I had a problem with my pump here in the UK. To replace the pump was a silly amount of money so purchased a seal kit and springs from a fuel diesel supplier, just needed engine code/year to ensure the right kit. Once done, perfect and no more problems.

I can relate some days I get no sleep and go to work at 5 am to diag a car like this keep it up man give mobile mechanics a better name

In Volkswagen and Audi it’s common to lose the pressure of the fuel on the high pressure pump just because there’s a suck fuel injector or rings and most likely the high pressure pump is ok, seal properly the fuel injectors system and you get back the pressure of the high pressure fuel pump.

Once again logical thinking and following a plan wins. Great job my friend.

Whatever it take to get the job done!! No matter if you have to off road, seal a boat hike a mountain or....cool man keep it up

For someone not familiar with diesels, this was a mean call to make. She nearly started but the hi pressure pump had gone too far. Nice fix to get her back on the road and on to the next one.

Thank you for the trip across the mountain, very interesting!

That road is smoother than the Pennsylvania Turnpike

When I think about New York, New York City is the first image in my mind. But the country side of New York is unbelievably beautiful. You're lucky to live there, Ivan!!

As usual Ivan does only what’s necessary and gets to the end result while being considerate of the customers wallet. I’ve been like that through a 47 year self employed career in home improvements and lived a nice life and never had an unhappy customer. Ivan will only get busier as time rolls on. My grandparents came here from Russia in 1908 so I have that in common with Ivan.

You did that once on another tdi and you called the high pressure pump at the time nice call!! But shame that you didn't get it fixed while you were there. But happy ending! Vw are bad for o rings not being replaced! At least it runs great now after pump and o rings! Great video!

There's never a dull moment watching your videos..

Nice catch Ivan and yes diesel can be very picky so are injector seals I've had a few over the years it didn't quite workout the first time I had to pull them and reinstall new ones all over again I just wanna strangle myself sometimes no matter how hard I try I to do a perfect job it always some new part that didn't quite workout.

I love how this diag started. Didn’t just jump to timing, but since no codes after clearing Ivan started with basics. LP Fuel, check. Then spark, and timing compared against known good. Then down the diag rabbit hole we go….BUT WE KNOW WE CHOSE THE RIGHT RABBIT HOLE because of the methodical approach. Always enjoyable learning from you Ivan.

Ya bad "O" rings on a diesel equals lower compression and a misfire. On a gas engine, bad "O" rings can cause vacuum leaks. Good one Ivan! Good thing you had that waveform from the previous VW diesel for comparison.

Nice frosty ride, great vew

Way to go, u created farfenugen with ur great diag skills, thanks for bringing us over the moutain

Another brilliant diagnostic.

Super diag Ivan.... mechanical science is a blast !

For those not too familiar with Diesel engines a good check of the condition of an injector is to do a "leak off" check. This involves checking the amount of Diesel coming out of the return/spill lines when running/cranking. Ideally all injectors should return the same quantity. A defective injector can leak back a lot of fuel and prevent the high pressure from building up. Also combustion gasses can come back up the spill pipes and into the LP side at the filter looking like an air leak. Keep up the good videos and logical approach.

that air in the fuel system reminds me of my mates diesel tractor, the petcock before the fuel pump had a worn Oring and was letting air into the fuel

Those tandem fuel pumps are known to leak fuel into the head. Through the pump shaft seal. And the pumpedüze system is great as long the injectors are seated correctly :)

Those older bhw engines can be a pain to get the air out of the system. High pressure pump on these engines are also a vacuum pump and arent that high of a fuel pressure. The injectors are what create the high pressure. As to adjusting the cam timing after it starts there is a data pid called torsion value want it as close to 0 as possible.

Ah, yes the HPOP. I have 2 6.0 liter Powerstrokes and I know all about the HPOP. My truck was almost new. I was coming on the interstate and the HPOP failed as I was merging in front of a semi; I had to take the emergency lane. The other was the Excursion; it just stopped like someone turned off the key. The best one was when the STC fittings failed. There must be 540 lbs. of pressure to start the engine. If those fittings leak, you don't get that pressure. We stuck a rag saturated in Ether (yes the glow plugs survived) in the turbo and cranked the engine. It went faster and faster until we got the pressure with the leaking STC fittings and the engine started. I got the thing to a shop, PRONTO! Great video!

You sure are a very brilliant man. And you are a great teacher

It the tandem pump, it quite common in europe, because it has a double job vacum for the engine and pressure for the injectors and sometimes has a inside leak and othertimes outside.

Nice diag Ivan. I was under the impression that the HP fuel pumps could be damaged if not R&R'd correctly.

For those torn up Allen bolts.., RBRT bits are the Bees Knees! Bought a set few years ago. No regrets.

ah yes, our beloved PDTDI

I might add the 04 and 05 Passat tdi has only an 18 month sale period in the US and not available everywhere. Only available in the US with the Zf5hp19fl trans.

Awesome countryside there, a lot like here in the PNW.

You are a born teacher Ivan. Do you have one or more teachers who taught you when you started that you would like to thank? The teachers I will always remember are Mr. Lukin, Mr. Manfre, Mr. Zipco, Mr. Nichols, and last but not least, my grandfather. They were strict and may not be everyone's cup of tea, but they taught me skills I use almost daily.

At first, I thought I had started a video of off - road recovery! I had an older VW diesel and sent the head to an expert head rebuilder in St Louis. After repair, the engine could not maintain oil pressure. Turned out the head had been line-bored for oversize bearing journals but had a cam with std bearing journals. Pulled the head and sent it back. The next time it came back, the valves were not recessed enough, and even with the proper thickness head gasket, the valves contacted the pistons. The third time the head came back, the engine ran ok, but a dope-smoker in Kia pulled out in front of me and I hit him at 45-50 MPH. End of VW diesel.

The PowerStroke system you referred to is called a HEUI it’s electronic based on extremely high oil pressures. As fir cam actuated injection systems that’s going back a ways in technology….. thank Detroit 2 cycle design from the 50s. I’m sure there are also more modern designs of that sort. Good work as always Ivan. And I’m personally choosing to have my wife to cut my hair. That’s one area I’m cheaper than you lol. I love reading the comments!

Good work man your really good at figuring out things like that b m w what a money pit

spaciba, hat's off Ivan 👍

Top man ....well done 💥💥💥

Those TDI engines ❤❤❤ 🥹🥹🥹🥹🥹 All they need a good maintenance and nice driving skills

That is the tandem pump, it makes low pressure for the diesel and vacuum for the brakes and other systems, there is a seal kit that can be replaced on these vacuum pumps ...

Their driveway will smell just lovely for the next year or so with that eau de diesel fragrance :)

Ivan thanks for sharing thank you

It leads one to ponder whether the air you found in the high pressure fuel system was effectively a failed "bubble test" that you would do on a 6.0 Powerstroke.

Great diag Ivan! I'm confused how the cam signal inverts on a crank no start, that makes no sense!

know exactly where that road is. Its a rough one, but a nice drive.

Basically this engine don’t have high pressure pump but they do have injector pump so best solution is take a rocker cover up take injector out and check 3 rubber o ring. To install injector you need adjustment. When camshaft pushed injector rocker maximum in you have to louse nuts and 6mm Alan key screws in maximum and return 180 degrees. After all jobs check injector connector they always to slope

Had fun with a Volvo V70 it was o one off in the garage and we were yoused to a type that had the crank pulley on with 4multi spline bolts,this one had one main crank bolt and a key way under it now the key way floated hard a tooth mmmm , so set timing locked of cam pump and kind off crank and put on new water pump and fitting timing kit gates

thumbs up, Doctor

Great video very informative

Hey Ivan I love the videos. Had a quick question, live data shows a fuel pump error as pressure drops and everything is brand new. Think it's a wiring issue or the ecu?? I know it's tough to say over the internet.

hi ivan when i go to diesel no start if it cranks the first thing i do is give it a wiff of brake clean if it fires its fuel then go live data to see pressures but i did have a jeep grand cherokee did few jobs on and owner replaced fuel filter became hard to start looked simmilar to one in the video it had a pin hole and was sucking air that was a pain to find did not leak fuel

Hi Ivan on the skoda fabia which is simlar, that pump is a tandem pump, as you say vacuum for brake servo and fuel pump, that pump only suppies a certain amount of pressure, the injectors them selves have a built in fuel pump that runs off rocker from the cam shaft, if its like a fabia...might be worth a look, might want injectors?...Fred in Uk

How was the oil level? The HP fuel pump failure was most likely ALSO allowing diesel to leak internally and mix with the engine oil. The level should be overfilled. However the leaking injector would have contributed to the oil level as well... Strange how the Cam signal randomly inverts. I would imagine a lot of techs getting stuck on that odd behavior and potentially misdiagnosing a no start condition. Great job, Ivan 👍

Would be nice of you Ivan, if you wouldn't do the purging of fuel line the russian way - directly on to the ground. I'm sure you can have it neatly done with some catching bottle or smthng. Liked the diagnostics still. Thank you

I appreciate the video . Interesting.. thanks

Had diesel same problem air in fuel high pressure pump seal failure exactly same simtoms

Ivan I hope you charge for wear and tear that road looked a mess nice video

My first thought was injector orings. If they're bad enough it will look as if the high pressure pump is bad. My practice is to replace any oring or seal that has been disturbed. I also use only oem orings since I've been burnt by after market. Especially on International engines. Never messed with vws but I'm sure same principles apply.

That was interesting, Thank you. But then again they all are.

Did you leave the timing different to the known good? After it was running was the torsion value set with VCDS on the scope or similar?

Master class!

It's a Volkswagen..... so, yeah. BTW -- Great job as always Ivan !

Hi Ivan, There is a pid in live data for that adjustable cam pulley. IIRC it's something like torque or cam torque. It's a number value IE 1,2, 3 etc. after a belt change you set the pulley to give the correct value in live data. Sorry I can't remember what it should be! I do know that it's a VERY FINE adjustment and a killer to get right. Most mechanics over here don't bother as long as it runs right lol I believe it does affect the MPG

next episode will see ivan work on a space ship, in the sky!

I thought Ivan would have checked high pressure pump/pressure/scan data I know he could not get it started. There's usually a minimum pressure that the engine demands to start. All good he knows his shit.

Great diagnostic Ivan! Great scenery intro too :-) Seems the other shop mishandled the repair (twice), masking the high pressure pump problem. Why don't customers call you first?

A little sniff of "Cosby Juice" tells a lot.

Beautiful countryside. What's the Bigfoot situation like up there?

It is a tandem pump (fuel-vacuum) Cranking dry kill them quick.

I don't think it needed the tandem pump as it was trying to start, probably the injector o rings and seats would've had it up and running. You can check the timing on VCDS under torsion value which should be + or - 3° to be in spec.

Saw on another show that the cam wave form was inverted because the cam was magnetized

As of yesterday I now have 5 TDI's. I bought a TDI Jetta for my daughter from a guy who had 7 TDI's and now has 6. With proper care these will last a long time. So far 3 are at 300K, 1 at 200K, and the newest 2015 Passat TDI at 80K. Here in Ohio the rust will take them off the road before anything else.

Always first and easiest step diagosing those pd engines is to check oil level.

Impressive work my friend

Hi, Love the show. Where did you learn your electrical skills? You are really good at it.

After about half the video I am thinking the high pressure pump is out of time. They are picky about that. Also could be improperly set tensioner.

I had one of these. Died when the balance shaft module ate itself and took the oil pump with it. My kids really miss the "Blue bouncy bouncy car" as they called it.

Hi Ivan, yes sure it had 2 problems, but they were actually 3, what about the camshaft adjustment back that you did as well. Thanks.

Any answers to your question about the camshaft position sensor signal: "why does it invert?" Maybe there is a sensor input that flips polarity to indicate a mode change for each cylinder, sort of a telltale for the technician....? (How many wires go to the sensor?)

I had a hard time with a sprinter van that had a similar filler it was cutting out every time it was going up hill with less than 1/4 of a tank so the first thing we did was check the pickup in the tank and it fell apart as expected fitted a new one and a filter and then it was even worse did a leak off test on injectors 2 weren't good switched them it was a bit better spent a long time checking things noticed air bubbles in the fuel line it turned out to be the new o ring for the one way valve that came with the new fuel filter was too small and didn't seal 😲

WOW- that was a lot of monkeying around with all that timing and pulses etc. A shot of start fluid in the air cleaner would have started the motor and told you you had a fuel problem.

1 bar coming out of a 3bar intank fuel pump ! Anything below 2 bar ya got no chance, and you can’t really get a reading on the vacuum pump besides the vacuum side as it’s a different chamber directly into the head. New tank pump ya in business

I guess after Diesel Gate VW Diesel cars disappeared in the US. I’m still wondering where they took them too. They had hundreds off them at a storage lot here in Washington State.

Gonna need a video soon I'm jonesing

Those diesel passats are very very popular over here in Europe

Hey Ivan where did you get your pico scope?

replace both washers on banjo bolt?

If fuel is not primed it can damage fuel pump because it’s not being lubricated. These diesel pumps are very sensitive and will fail if you run them dry
