Hello, You have set the rockarm to the lowest point on the injector that you’re adjusting, after that you screw the injector screw all the way till the injector spring is fully compressed, after that you unscrew the injector screw minus 180°. Do the same procedure on all 4 injectors.

You have to set the rockarm to the lowest point for the injector that you are adjusting, after that you screw the injector screw all the way till the injector spring is fully compressed, after that you unscrew the injector screw minus 180°. Do the same procedure on all 4 injectors.

Thank you, the injectors bolts are stretch bolts so it needs to be tightened in 2 steps, first tighten the bolts to 3nm and then further 270 degrees, in that way the bolts stretches properly. Small advice, each time you removing the injectors do not use the old bolts because they could snap, use always new bolts.

Depends of the engine code and type

Hahaha, thank you

This Piezo injectors don’t come with the washers.

@@audilover6591 where’d you get your seal kits from fella?

@@MMmmm-nq7cz I ordered them from my local car parts dealer, I ordered the complete kit with the stretch bolts from “elring”

Most likely are the seals

Hi Carlos, it can be few things: ~ one or more used injector can be faulty ~ faulty or damaged injector wiring loom What you can do is test witch injector or cylinder bank is faulty. You should disconnect the injector 1 wiring and try to start the car, if starts (engine will work roughly) that means that the faulty injector is the one you unplugged because the engine can start with 3 other cylinders. You have to do the test with all 4 injectors in the same way What you can do is

@@mihaimihai49 -180 degrees is the state from the VW workshop manual. I did more then 5 cars in the same way and no defects at all.

Po meni to su najbolji 2.0 tdi pd motori, to je ubiti stari 1.9 tdi koji je malo moderniziran i ubačene su pd sprice. Auto je u obitelji od prvog dana a sada ima 255k km i stvarno nije bilo problema osim nekih uobičajenih problemčića ali to prepisujem ugrađenim rezervnim djelovima. Jednom je propisala pumpa vode (Continental) nakon samo 50k km ali to je potrošna roba ali ajde. Inače ti PD motori ne voli gradsku vožnju jer vole počepiti usisnu granu i egr tako da moj je savjet to skinuti i ugasiti softverski jer inače će biti čišćenja kao i u mom slučaju. Sve u svemu toplo preporucam

I used a metal cable tie, before you pull them turn them around a little bit. When you pullin out wiggle a little bit.

Hi Robertas You have set the rockarm to the lowest point, after that you screw the injector screw all the way till the injector spring is fully compressed, after that you unscrew the injector screw minus 180°. Do the same procedure on all 4 cylinders

I didn’t need any additional tools

Perfect thanks

Hi Aliiswell It’s really hard to tell what could be without being there and test the car. My opinion is that could be some electronic issue like for example (map or maf sensor, injector harness or even the acceleration pedal). With the VCDS you can check all off them and see the readings. Try to remove the map sensor that is situated after the intercooler, sometimes it gets really dirty so doesn’t giving you a good reading

@@audilover6591 thanks for your help 👊🏽👊🏽

All the pistons are set in the same way. In the description of the video you can find the workshop manuals. You don’t need a locking tool

Yes, it’s all the same. I did one BKD engine couple of weeks ago.

No need to bother with compression. Just be sure tu but then back in place nicely, they need to do a small “klick” when they come in place.

Yes, that’s correct, the injection screws must be changed every time you remove them because that are stretch bolts so if you stress them they like to break

Hi Cristiano, Yes, that’s correct, they are “stretch” bolts so once installed it’s not recommended to use them again

@@audilover6591 Thanks for the quick response, they changed an injector for me and they didn't change the screws, will they break later, do you think?

Now they have put the same screws on me, can they break once installed? Or when they are removed can they break inside the engine?

@@cristianrullo it will not break, but it could when you will remove them.

OK thank you

Hi Dany Yes I used an ultrasonic cleaner with a heated solution. I order my one on Amazon. www.amazon.com/VEVOR-Commercial-Ultrasonic-Capacity-Solution/dp/B01HGNM5WE/ref=mp_s_a_1_3?crid=N5J0ETE1TRH4&keywords=ultrasonic+cleaner&qid=1647159921&sprefix=ultrasonic%2Caps%2C293&sr=8-3

Yes, that are “stretch” bolts so they need to be replaced each time you remove them. If you reuse them they have tendency to snap.

Jesam, Rijeka

I had the same issues like you described, long crank and white smoke at the start. My car had also a bad injector so sometimes my car was shaking at idle

​@@audilover6591 Thanks for your reply. I have two more questions.\ Which torsion value is best for these types of engines - 125KW pd siemens, 2007. year? Someone says 0.0 and someone tells me -2.5. Who should I trust? :) And when I set the intake camshaft to the desired torsion value, is it necessary to synchronize the exhaust camshaft with the intake? Or do I adjust the exhaust independently?

@@radulepg I didn’t adjust the chamshaft, I just adjusted the injector after I reinstalled them. All the information you need you can find in this workshop manual on the page (36,37,38). drive.google.com/file/d/1hrboC0VOFb2LMrjOJI3znleTybrVgiKZ/view

​@@radulepg Every engine will have its best efficiency at different torsions. Mine was set at +1.84 and after setting it to +1.09 it has best mpg's (I have done different adjustmets and about 7 good runs)

No, I changed only new injector bolts (03G103385A), they must be changed each time because they tend to snap if you reuse them.

@@audilover6591 Yep, I know that. I've been curious about head bolts. Both of these items should be replaced according to Elsa/ErWin workshop specification. Cheers from Poland :)

You can also add in your description manuals for other. i.imgur.com/bmfmPSw.jpg i.imgur.com/Tl4q1kR.jpg i.imgur.com/SWdeyds.jpg

@@sebastiandamian4936 yes, you’re right about that. I will add the manuals in description, thank you

It would be good after you run on Diesel Purge to run it on plain diesel. The reason is injector seals, diesel purge can destroy the seals if you leave it for a long time.

Use torque wrench

NM is newtonmeters. You might pe used with poundfeet. It;s the measure unit for Torque. If you follow closely what happens in this video, sometimes he decides that the tightening required after the torque wrench is maybe too much, and he does a little less, maybe for fear of damaging the bolts...

Could be. Does the car suffer hard start after 1-2days of non starting it?

@@audilover6591 yes

@@Max-io3he then the cause is probably seals

Hi, I bought it on Amazon

@@audilover6591 is the liquid mixed with water or is it 100% liquid?

@@dainisfjodorovs20 I mixed the liquid with demineralized water

What kind of issues you have?

@@audilover6591 when I drive around 60mph plus in 5th gear on the motorway my cars power cuts low and the coil light comes on. When starting it has slight cold start and exhaust smokes, excessive fuel smell and misfires.

@@DONN-24 sound like an injector failure, the only advice I can give you it’s to take the injectors out and find somebody that can test them and refurbish them, or try to find used ones. The problem with piezo injectors is that they are a bit harder to refurbish so some companies don’t want to deal with them.

@@audilover6591 thank you very much for the advice, really appreciate it. Do you have a garage or know of anyone reliable?

@@DONN-24 I’m not refurbishing injectors, for sure you have a company in your country that are doing that. Where are you located

Hi, thank you. - I was turning the engine on the crankshaft pulley, (need to remove right tyre and remove the plastic around the wheel. - I use the pliers to connect the glow plugs harness. - I think you need a new harness for the injectors because I don’t know if there’s the same connector because the BMN injectors are using piezo coils, I didn’t do that so I don’t know the answer on your question. - You can buy seals and bolts trough the Audi dealer. I bought mine from Autodoc, elring is the manufacturer.

thanks for the reply -sounds easy enough -iknow i need the bkd plugs but not 100% sure if the harness will fit, -is that a good brand for long use or just a cheaper option? What was the process after tightening the injectors and plugging in the plugs, did you have to turn the crank to a certain point or anything? Was was it turn crank to allow fuel or something then put gasket and rocker on and start it?

@@itzjordxnhd9850 Elring is really good brand for seals. After I adjusted the injectors to the spec, I turned the crankshaft for 2 full circles to be sure that everything is ok, the I changed the valve cover gasket and tighten the cover. Before the start of the engine I turn the key for few times so the fuel pump can deliver fuel, then I start the engine. The engine will straggle to star because lack of fuel, you can expect a bit of white smoke after first start.

@@audilover6591 what brand bolts did you buy? Did you do anything about ‘injector lash’ or is that when you’re tightening the bolts?

60°C for 15min

@@audilover6591 Awesome, thanks 👍

@@audilover6591 Great Video, but Elsawin states the following: The actual cleaning process commences when the temperature reaches at least 70 °C and must last for at least 90 minutes. After 90 minutes, switch off cleaning process by pressing ► button -D-. Remove unit injectors from mounting plate. Allow unit injectors to dry in ambient air for max. 1 hour. (Never immerse the complete unit injector in the cleaning solution.)

@ good point. Thank you for the advice. I never submerged the whole injector, but thank you that you point this out.

Thanks for info What product do you use to clean it ?

Sorry but I don’t understand your question? Can you write in English.

It can be few things, injectors seals and also the tandem pump. If you have faulty tandem pump sometime the tandem pump seal start to leak and mix the fuel with the engine oil. You can check this with the deep-stick. Also can be dirty injectors. You have the video on my channel how to flush the fuel system with liqui molly

@@audilover6591 Probably is not the tandem pump, because the oil level is still the same (if yhe pump mix it, the oil level will goes up?). Yes, I saw the video, and this week I'll do that. Just need to get the fuel filters and other stuff to do. But I think is the seals(can be wrong regulation) or worse, some of the injectors... Thanks

@@petarsoftuni6874 true but my tandem pump failed without mixing fuel and oil. Hopefully you will sort it out.

Hello. Could be air in the fuel system. Also my car had a hard start for the first time after I cleaned injectors. What I did is that I put the ignition ON for 10 times (wait for 5sec between the cycles) without starting the car, I did that just so the fuel pump in the tank can pump the fuel up to the tandem pump to prime it.

@@audilover6591 thank you for responding that quick. I’ll give it another try tomorrow 😊

Here I am again. Started fuel pump activation via VCDS several times. Engine is Running!!! Only problem is, that it’s smoking heavy and runs restless now. Any Ideas?

@@Skjaxon did you adjust the injectors like on the video? Do you have Piezo-VDO Injectors

@@audilover6591 It’s a Golf 5 (2008), BMN 170hp engine. I adjusted them even with a dial gauge and turned the screw back to 180°.I Followed the VW instructions including all the new screws with the right torques. After it ran for 15-20 minutes in idle, I turned off the ignition. From now on it didn’t even ran in idle anymore. When I made it running, it only ran with a little throttle. As soon as I took my feet of the Pedal it ran out. No failures in engine memory are saved.

I’ll do this procedure tomorrow. I’ll use regular gasoline as cleaning fluid put in a glass jar. The jar is then submerged in the water bath (tap water). Use no heat. Faster than anything. There are a couple of videos here on CZcams comparing gasoline with a couple of other cleaning solutions. Gasoline clear winner.

Do you have any other problem then just burned oil? Did you do the compression test?

@@audilover6591 no compression test Just burning oil. When I done an oil change it, the old oil was VERY thin and stank of diesel.

@@toddy9141 also can be that the upper seals are not good and you have a leak of diesel in the cylinder head, this can be the case. Try to open the cylinder head cover and investigate.

@@audilover6591 thanks mate 😃👍🏻

@@toddy9141 no worries. Good luck
