It won't. If no power is delivered to the injector solenoid the bypass valve is left open and all the fuel goes back to the return line. The only way it could hydrolock is if the needle is catastrophically damaged or the internal needle spring is broken
@@Theorangeman. Those are different indeed, in the Bosch PD units they have a spring pushing against that bypass valve, if no signal is received, they default to open, flow towards the return line, and blocked flow towards the cylinder Edit: there's an official VW 1h course on how PD injectors work around RUclips somewhere.
The opposite. If you remove connector from good injector, engine stall or turn off. With bad ones keeps running but a bit rough. In this case 3 injectors seems to be bad.
The PD injectors are some of the most reliable injectors as there's not really anything to go wrong in them, excluding wear and tear over a looong period of exploitation, and even worn out they work RELATIVELY fine. With modern cars I agree though, they made them too complicated
It's only running on the 3rd injector because it kept running one each pull but the 3rd. He restarts the car then pulls the 4th meaning as its still running the first 2 and the 4th are shot. Replace them all basically. Be back doing the 3rd pretty soon. They come out in two's too. 🤷🏼
Surprised he's still got fingers 😂😅
A piece of cardboard in front of the manifold helps direct the oil back into the engine and not onto the driveway!
If you unplug one of them injectors in the open position its gonna fuel hydrolock itself

@@gtaseedis it not like the bosch ones where depending in what position they are opened in they can stay open. I know the piezo do this

It could possibly have been the injectors harness at fault?
That one works 😮😂
Damn they put the injectors in the actual valve train? Volkswagen!? Well duhh😂
Injecteur number 2 is the pilot injecteur
I will rather remove all 4 and repare them,than doing this madness
I lost a lot of oil and my Passat has become oiled while I was fixing the solenoid valve but I did it finally
I don't get this so if you remove the connector from 1 that's not working the engine will stall ???
looks like yes

@neceonanidje894 genius. I will try this now on my dying caddy. I'll use grips though. Not fingers.
So replace them all but basically it's running on 1 injector.
😂
Estan fallando 3 solo 1 esta bueno?
nice mess :-)
I hate VW and their engineering
Miért?

This... is not right....
Why?
So what? No explanation!

@@mikearthur2586 I believe you count reversal! Number 2 is OK , 4,3 and 1 are faulty. Do not know what you mean "shot" !
@@grosseader "shot" is just an English way of saying broken.
