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!

[@jensole2617]

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…😊😊😊

Hi Ivan, I enjoy watching your videos. I’m not sure if you will read my comment but watching your video I think that the tandem pump was probably OK what I think the real problem is or was is that the injector has copper washers that seal it to the piston to the Head to the cylinder and you must tap the injector down when you anchor it and bolted in place, and if those copper washers, those crushed washers are not sealing to the cylinder, then compression will push up into the fuel and the car either won’t start or if it starts it’ll eventually die because of all the compression getting into the Fuel And that’s why you were getting air in the fuel because compression was pushing up past that copper washer at the bottom of the injector. If you would take off the return line to the fuel filter from the fuel pump tandem pump and put it into a jar take the glow plugs out and crank the engine until fuel flows into the jar, free of air and you will see fuel spray out the Glow plug holes, then put the glow plugs back in and the car will start, but if compression is leaking past the injector into the fuel cavity, then the car will eventually not run properly

[@markt5426]

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.

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!

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 ...

[@bobytrap.j9793]

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.

[@fieldsofomagh]

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.

[@pichacker]

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.

[@marion1600]

This works for a common rail diesel not a pump injectors

[@lucianlucian9911]

That is true, for PD systems there is no return line to check for leak back. Also the PD units are quite inaccessible, as they are buried beneath the camshaft.

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.

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.

That is a PD engine, so the injection pressure is produced by the cam lobes for the injectors. The pump on the end of the cam is only intended to maintan flow through the gallery in the head at low pressure, so not a high pressure pump.

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 👍

[@55peterf]

The German PD engine is unlike most diesel engine tough long living and a very reliable uncomplicated design. Would need to know more on how and what was swapped out on the head from the old one. Important as the injector o rings are they should always be renewed when injectors are disturbed. If leaking the engine oil will dilute. Mechanical operation to pressurise injectors via cam lobe and triggered electronically. The rocker to injector clearance must be set correctly - wind off adjusters, set cam lobe clearance at max lift on each injector in turn, and wind in adjuster until bottoms out and you feel resistance. Back off adjuster off half a turn. This is the basic method to ensure the cam lobe doesn't hammer out the bottom of the injector. Also recommended all cam cap stretch bolts are renewed on assembly. Have seen these come loose Also check in tank pump and that the tandem pump is being pressurised these can commonly fail and while the tandem pump can sometimes lift the fuel from the tank once the system has been broken into it sometimes fails with starting issues resulting. Wiring looms to injectors under the cam cover can also cause issues as loom and contacts become hard and brittle working in hot engine oil they break down usually starts with a misfire. The tandem pump, fuel and vacuum, can be tested for pressure there is a port on the side to connect a gauge. Not as high a pressure as you might imagine. should read 3.5 bar at idle and 7.5 bar at 4000rpm. Additionally at idle, the pump should return back to the filter head 1.2 Lpm at idle. These don't commonly fail in my experience and I would be asking why would it suddenly fail just because the head has been changed.

[@rkan2]

The PD is in no way as reliable as the regular TDIs with a distribution pump. The camshaft and lifters are much more vulnerable. They are still reliable usually, as long as you make the right choice with oils. With the predecessors you can use many oils ans they still run great.

A couple of things about these cars is no one here wants to work on these. I have a 2000 golf tdi and only one shop that specializes in TDI's will work on it for a premium that's almost 200 miles away. Another thing is when I changed my fuel filter, I even filled the new one up with diesel and it ran for a second and then took 2 full charge ups on the battery, then the battery and a new starter later to get the car to start again. It was a complete nightmare. If I want to change the filter again, I need to get technical with all kinds of vacuum tools and such to get all the air bubbles out because once they enter the injection system, it plays with the sensors. That's why you never want to run these out of fuel

Just crack that high pressure port on the back of the HP pump to bleed the air out :)

I do all my own work on my 2000 Beetle tdi and not just to save money but to make sure it is repaired with care in a timely manner. The tdi specialist in my area is booked for weeks in advance and has made mistakes in the past. I replaced the fuel filter in mine in 2020 when I purchased it. It had a 2009 date of manufacture (about when the VW service contract ran out) so they can go a long time without changing. Mine started without problems (I filled the filter with Seafoam).

Fortunately on the newer engines (2004+ in the US market), the system is self-priming (except when the tandem pump has an internal leak like this car!). Takes about 30 sec of cranking after a filter change, but with the right scan tool you can activate the lift pump. I did that last time I changed the filter and it started right up and never died.

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 😲

Is that a BEW engine? ALH is a bit more fun with the injection system, the pumps start sucking air. Can be fixed w/o pulling the pump(bad idea) by changing most of the orings insitu so watch for that.

BHW with a time bomb balance shaft that messes up the oil pump drive shaft and jumping chain drives. Also engine has less oil capacity due to the space the shaft module takes up in the oil pan.

[@theweekthatis]

Those tandem pumps are always like that. Take ages to purge. Bet that's all that was wrong the begin with.

[@johnfairchild3421]

Got to have good pressure and no air in diesel system at all
