Well done mate, good fix 💪 I know you were disappointed with the 1st video but I would have just kept it up and pinned a comment to explain a bit. I have left out or mis spoken on videos about certain things and it's always a frustration, but at the end of it you are giving out useful info to people 👏 we are in a busy work environment trying to diagnose and fix whilst also explaining in detail, not easy and very easy to leave out things. Keep grinding and ignore the negatives, it's all part of it mate 👌👍
Thank you for the very uplifting comment Gerard and you are completely right! Thanks for supporting me! P.S I just subbed to your channel. Man you have a lot of vids!! Looks like I'll be busy this weekend :)
@@romanosautomotive All good mate, I got nothing but love for the community and industry, I love seeing new content creators on YT that are diagnosing problems (highlights the good work techs do) it is my lunchtime vids everyday 😁 (I may have a problem 😂😂) PS your diagnostic trolley is literally the one I tried to source for over a month and it's discontinued, you are a lucky man, that kincrome one looks 😍 😥😢 Very sad they can't get them back in
Me too! Always keeps me entertained watching all the cool guys on YT. Now you're on my list! Haha, it's a great diag cart but you know, there's never enough room!
@@romanosautomotive Cheers for that, sounds like a good list 😁 we will never have enough room but as far as tool carts go that one looks mint. Anyways I best get back to editing, loads of footage and not enough time 😂 Keep up the good work.
hello, I have, not all the time, and often when I drive error p0201 injector circuit open cylinder 1. the preheating warning light flashes, and the engine vibrates. I changed the 3 injectors, and I measured 2.56v on the connector plug without starting the car. I am lost and I do not understand anything.
What voltage are you getting at the injector plug, I'm getting 4-7volts depending on the rpm on injector 3 can't check the others as it won't start on 2cyls
Very good job, can you explain why is on power ond ground side of injector same voltage pattern. Doesn't make sense to me how can be current flow if ground and power are the same.
It is not exactly the same, it's power and ground one way when the pcm wants to expand the piezo crystal stack and then the pcm reverses the polarity to contract the piezo crystal stack. When you scope both wires it gives the illusion of being the same because its essentially doing the same thing just at different times, wire 1 power and wire 2 ground at one moment, then wire 1 ground and wire 2 power the next moment. That's why the current waveform has a positive current ramp followed by a negative current ramp. I hope that makes sense.
Noice. More than 1 way to skin a cat, not that I condone that sort of behaviour. Whichever technique you use that you are comfortable with and provides the correct result is the one to go with
Good explanation of the injector operation. I never new the were controlled like that. Learn something everyday.
Thanks Dan. It's a great trade because there is always something new to learn!
Thank you for sharing the diagnosing and fix process with us Rob. We always learn something new from your videos. 🍻👍
Thanks for supporting me right from the very start Aldi!
Sometimes the best wiring diagram is the car! Thanks Rob, another good video.
Not wrong there Jeremy! Thanks for watching!

Awesome content Rob! Keep it up! Found This awesome channel trough diagnosedan FB page. 10/10
Thank you Robert! Much appreciated!

It would be hard to try and help you over the internet. Are you a mechanic, do you have any very good mechanics local to you?
Well explained nice video.
Thank you for watching D. D!

great info bro
Appreciate it brother!
Good evening my friend and nice to meet you!
Im having an issue with my vehicle, are you able to help me out please?
I'm not sure how I can help. What country are you from?
@@romanosautomotive
Good morning my friend!
If you are not able to help then i understand no worries.

@@romanosautomotive Thank you for clarification
Nice diag new subscriber
Thank you Ian. Much appreciated!
Good to see ya Ian, great minds think a like! 😂 😂 😂
Whare are you? Are you too in Europe? These are the norm for us :)
In Australia. Whereabouts are you? I've done a lot of these injectors lately on VAG cars. Same for you?

Absolutely Kirk! The great thing is that we have a great network so we can share all of this stuff together
