I watch many of Dans friends “in the industry” and I think everyone of them would themselves agree Dan is second to none in the extra effort he puts into every video to deliver the point. This man could save a few hours being a little lazy and still have a great video. Hope even casual observers can appreciate the extra mile I see Dan goes through. Absolutely a master technician.... I would though add the adjective elite. Dan is an Elite master technician. 😂🤷♂️ Dan - thank you for being a content creator. ❤️
DiagnoseDan don’t be afraid to monetize however you can. You can make a s-k- style “save a million by adding this to your gas” but I’d watch a video of you boiling water like man I am about to learn something I did not know. 😂 It’s an exaggeration but only slightly. You should be at 10M subs but on your journey don’t fear finding the balance between effort/end result.
I already said that Dan is the number 1 channel for someone to really learn about how things work in a car. One more time thank you so much for all your effort Dan. Greetings from the north of Portugal 👍
@@unkownKalliii It's true this chan is criminally underrated! I mean not so many subs when you see the quality of the content and the work that must go into creating said content. I hope Dan will get to 1M subs soon!
So many skills and talents ‘rolled up’ in to one guy, natural diagnostic, filming and teaching skills, plus a superb sense of humour, Dan you’re a one of a kind!
Jaz Syed I’m in the front row bringing an apple everyday. The really cool thing is teach (Dan) can wrench to. It looked like there were two or three cars all tore apart. He’s not just a brainiac.
This is the only auto channel I watch regularly, nobody is better at explaining how car stuff works! I always look forward to your next video, thanks Dan!
No wonder there are so many average mechanics out there. Such complicated systems, and so much specialty knowledge needed. YOU HAVE TO HAVE the diagnostic tools, and know how to use them to your advantage. Well done Dan.
i am ending an electromechanic training course!! and in two weeks i will go to a garage for practises !! i learn much more with one of your videos than in a week at the school!!🥰🥰🥰🥰🥰🥰
It's amazing how clearly you explain everything, and in a second language too! I've been learning Dutch for the last 10 years, but I wouldn't be able to describe the work I've been doing to my Renault to bring it back to roadworthy condition. I think I ought to try learning some technical vocabulary.
I just want to say your videos are absolutely fantastic Dan. I learn so much with your expert knowledge, thorough explanations and your attention to detail. I have reasonable mechanical & electrical knowledge but modern vehicles are a beast of their own. But after watching all your videos I have picked up so many tips in each one and now I am confident to whip out my scan tool and understand the numbers in a modern vehicle. I just wish you released them more often but with the level of detail you go into, I understand how time consuming to film that would be. Anyway thank you Dan, we all really appreciate the work you do!
Glad you are still smiling man! And my old rig with twin SU carbs looks better and better, grin. Truthfully they had maintenance issues too, but common hand tools and some regular care and attention was I needed to start and run well, winter or summer. And give a starting boost people who would not do the work, no grin.
Dan, is the type of Technician we need in our region!. The most interesting part of Diagnotics when you teardown parts and explain how various components work.! Dan u are a genius!🎉
Hi Danny, Great video again! Hope you, your family and friends are doing fine in these strange times! Really good design of Opel: when the pump is leaking it doesn’t mingle with the engine oil and all the bad results of that fact. As we experienced with the high pressure fuel pumps of VW. Keep up the good work and all the best Kind regards; Geert
Muito bom trabalho, sem dúvida um grande técnico, tens sido uma inspiração para mim, desculpa não escrever em inglês, um abraço de Portugal.. É por favor continua o bom trabalho..
DAN, GRAPHED DESIRED FUEL PRESSURE VS ACTUAL FUEL PRESSURE AND I LOVE HOW YOU SUPPORTED YOUR LOGIC WITH TAKING HIGH FUEL PUMP APART AND SHOWED THE DEFECTIVE DIAPHRAGM. THANKS. YOU PUT IT IN PRESENTATION AND PRACTICAL PROOF. YOU ARE BLESSED.
You absolutely the most dynamic mechanic here. It is obvious you are explaining every last detail. I bet in a real situation you guess the problem instantaneously. For a dummy, like me, you are a saviour.
You posted this a year ago! And you've just saved me about £130 in labor costs. I'm not very good at cars but i had the same problem with our zafira 2.2 direct injection. I fixed it myself with the help of your video and my dad's input. I can't thank you enough, I'm now a subscriber forever of yours. Thank you again for this video 👍🏻👍🏻👍🏻👍🏻
Your videos are so good that even me that not understand the English very well, understand you and I´ve learned so much from you, thank you very much Dan, you are a great teacher for me. I´m Colombian, and I always mentioned your videos to my colleagues and friends, but unfortunately they understand the English less than me
Fascinating to watch your videos Dan. I wish we got someone like you here in the UK. Most of them here are not mechanics. They are trial and error, fitters ...
Same goes to Singapore too.. We hope that there is many of such diagnosedan mechanics, but seems like majority are trial and error. Yeah so diagnosedan is such a gem.
i only came across your videos yesterday evening but have watched quite a few now cant stop watching . nice to see a mechanic not afraid to get their hands dirty and not wear rubber gloves your videos should be mandatory watching for any apprentice mechanic you are not only a mechanic you are an electrician a producer a host a editor a teacher and it would not surprise at all if you were playing all of the instruments in the music on your videos
Very clear, concise explanation. No rambling or rants. Just easy to understand processes, techniques, and diagnostics. Thank you for your good attitude and clean family friendly language. I appreciate you and feel comfortable recommending you to anyone!
Well done Dan !! Working on a car that is somewhat reputable for the owner is a sense of pride. I fixed one a month ago and can tell you the owner was very disappointed with the car. According to what he said, the car has been in the shop way to often. Stated that will be his last car type. I liked doing the job because of the easy access to the pump. Have not seen the car since the repair. Hopefully no news is good news. Peace and out. VF
DIAGNOSED DAN FIX IT AGAIN, your explanation is so smooth you could explain to a baby and he or she would understand hence none of your videos missing me.
The same problem was, the error code showed the pressure regulator. Reading the UK forums, however, it turned out that the high pressure pump error still. After the pump change (Continental) the engine is running as it should! thanks Dan, very good explanation and good video!
How i which we could have such a trainer's in our country we could save so much and bring so many cars from the scrap yard i like the way you approach the faults i feel much a pro by watching you educational video's .I've gained much from your channel. Keep it up my guy.

I have been in the motor trade for 30 years + and also college lectured. Dan you have got to be the best I have seen at explaining and visually demonstrating without being over technical online I have seen, really enjoy your videos. Frank
yes most of us went for the HP pump .. but we're here for the diagnostics right, very interesting and good to see exactly how it shows on the scope, thanks for another great video and clear step by step through to the fix.
Well worth a second visit .. I have a thick skullm and the slow intake of info is more than likely down to my 78 years .. even greater video second time around .
GREAT video Dan. I thought we were done when you made the call on the pump. But, of course, I was wrong. Nice work on the tear down, explanation, and theory.
Each Time i saw your video i hit the like Button before watching it, because i knew that will be extremely interesting ! Thanks Dan for all videos that you make, Big respect man !
I’ve just finished my 4 years apprenticeship and your video helps me a lot to under how to Diagnose the car’s problem step by step to be a good mechanic .. thanks Dan!
NTC sensor: corrosion can drops internal resistence to zero. The circuit sees the temperature to infinite value . PTC sensor: In 0 resistrance the temperature is very low Very nice video boss
Thank you DiagnoseDan for another interesting video. You are really very good at explaining stuff. Brilliant! What is not so brilliant is that you have to replace the whole high pressure fuel pump. The three rubber membranes are obviously a week spot so they should be a replaceable service part. And of course not plugging the oil filling hole permanently. Another example of bad design! So much for the car industry claiming they are "green". They just don't care. Only money counts!
Absolutely brilliant!!! there's nobody else better to diagnose problems. love this channel! fantastic at teaching stuff in plain English too making everything 100% clear and very educational! a real hero
I know very little about the GDI system, only what I've read. My 2020 Toyota RAV4 with a 2.5L 4 cylinder has the GDI pump. It's not as noisy as some others I've heard, and performance is pretty good. Thank you for the explanation and diagnosis.
This guy is a master technician!
Yes he's a real mechanic and so is LM auto repair
I think he more like Magician
and excellent teacher
Thanks😁

I agree 💯! He is the best on TH-cam on my opinion!!
Wish you uploaded more frequently DiagnoseDan, your videos a 10/10
I wish i could👍
I think this 20 Minute Video is about 3-4hours of work 🙃 and brings no money 😅
@@unkownKalliii It's true this chan is criminally underrated! I mean not so many subs when you see the quality of the content and the work that must go into creating said content. I hope Dan will get to 1M subs soon!

That was the best explanation of direct injection fuel delivery I've seen.
Thanks😁
Yes I agree.
If I was at school , Dan would be my favourite teacher! 🤗
TH-cam school😉
Jaz Syed I’m in the front row bringing an apple everyday. The really cool thing is teach (Dan) can wrench to. It looked like there were two or three cars all tore apart. He’s not just a brainiac.
Hands down the best diagnostic tech on TH-cam, bar none!!!!!
Thank you very much 👍
I am mechanical engineer and this guy is doing an excelent job. Best and logical analysis I have seen here on youtube.
This is the only auto channel I watch regularly, nobody is better at explaining how car stuff works! I always look forward to your next video, thanks Dan!
Wow thanks David😁👍👍👍👍
No wonder there are so many average mechanics out there. Such complicated systems, and so much specialty knowledge needed. YOU HAVE TO HAVE the diagnostic tools, and know how to use them to your advantage. Well done Dan.
Thanks!!!
The ones that dislike you're videos are just envious dudes, that they wish they had your. Knowledge
😉👍
They're the ones that replaced everything except the HPFP!
This guy is the guru of codes diagnosis
Yes I love your videos, must have info, and understanding of how modern cars work. well done.
Thank you 😀

Almost no one but you can have such a good method of teaching
Thanks!!
Another video beautifully produced my friend.
Thanks Keith😁
Man glad to see you comment here. Please post a new video soon. Its been a while since last time you posted any.
@@mansouralblooshi3004 I promise once I settle a few more projects, I will be back with new content for you
There's a lot to be said for carburetors, cars are far too complicated now. Well done for sorting it.
We love DiagnoseDan, love from Nigeria ❤️
Thanks!!
this is the guy the so called master techs go to .Amazing. doesn't throw parts at cars but analyzes the problems like a sherlock holmes.

Awesome skills, great job! I believe VW/Audi have the same issues with those pumps - as in one of your videos.
You are right👍👍
Love how you tear it down and show operation of the HP Fuel INJ Pump Dan! Thanks for this video!
My pleasure 😀
DD is our favorite European guy in the continent 🔥
Thanks!

Thanks Geert and Stay Safe 💪
They just don't make rubber seals like they used to. Good work Dan & your rundown on why things break on cars is uncanny!

Pleasure to watch as always 👍
Thanks!!!
Great vid again Dan. Just shows how misleading error codes can be in the hands of those who don't have vast experience.
Great video, you should have many more subscribers.
Thank you 😀
Love your videos, even tho i ve been a mechanic for long time, i always find myself learning and learning.
That's really great to hear!!
Steady on Dan, it'll need a new pair of front tyres if you keep driving like that 😃😃
Just once for the video 😉
You absolutely the most dynamic mechanic here. It is obvious you are explaining every last detail. I bet in a real situation you guess the problem instantaneously. For a dummy, like me, you are a saviour.
i love this guy - totally awesome

Dan, Please help me. my son is got a vw polo 2010 ... 1.4 . AC stopped working. where do i start., do i need to change the AC compressor?
Long time no see Dann
You fix it again 😊
I'm back 💪👊😁
Dan, hi from Russia. You are master of diagnostic. You are doing a great job. Thanks.
Thank you very much 😀
My day was bad, Until DD arrived.
Sorry to hear your Day was bad, but glad i could change that 😁
i only came across your videos yesterday evening but have watched quite a few now cant stop watching . nice to see a mechanic not afraid to get their hands dirty and not wear rubber gloves your videos should be mandatory watching for any apprentice mechanic you are not only a mechanic you are an electrician a producer a host a editor a teacher and it would not surprise at all if you were playing all of the instruments in the music on your videos
Classic hole in the rubber trick....
Be carefull with that trick😉
@@Diagnosedan it's very expensive I hear....
😂 we are all guilty of that at one time or another
I learn something each time i watch your videos. Thank you.
I love how you don't just slap on a new pump and call it a day - you took the old one to bits and showed why it failed and how it works.....love it!
Glad you liked it!!
I feel I am proud of myself as a mechanic watching you, Sir Dan.
He’s at the very top of his game! Well done.
Could have done with him to sort my VAG underboost fault!
Always enjoy your videos and how you break everything down and explain how it works always a professional Thank you Dan.
Very clear, concise explanation. No rambling or rants. Just easy to understand processes, techniques, and diagnostics. Thank you for your good attitude and clean family friendly language. I appreciate you and feel comfortable recommending you to anyone!
Thank you very much John!
Another great video,i am addicted to these videos,like a detective novel to find the guilty.
Only just found your channel....Very impressed with the way you work.

Thanks for sharing your story VF
Thank you Dan. Good job again. Have a blessed and safe week to you and your family.
The same to you and yours Billy👍
I swear u r the best I've seen so far on the net sir Diagnosedan....
DIAGNOSED DAN FIX IT AGAIN, your explanation is so smooth you could explain to a baby and he or she would understand hence none of your videos missing me.
😂😂👍
Thanks Dan
Seeing the inner workings of the high pressure fuel pump was great in itself, plus the diagnosis.
Excellent.
Great work, DD - diagnosis and remedial.
Enjoyed the pump strip, best bet to replace! 👍🏻
Damn! You always explain systems so clearly. You make it easy to follow and understand. Thanks, Dan!

Love this guy no cutting information given the best look and information
Dan is a master troubleshooting technician, and I always learn a lot from his video.
yes most of us went for the HP pump .. but we're here for the diagnostics right, very interesting and good to see exactly how it shows on the scope, thanks for another great video and clear step by step through to the fix.

Dan is so badass, there aren't any Opels in America but I still watched the video
But i think you do have the same Ecotec engines in GM models.
Thank you DiagnoseDan for another interesting video. You are really very good at explaining stuff. Brilliant!

Always look forward to these videos, not only a master tech, but a great teacher. I've learned a lot.
Thank you
Just the video i needed for Zafira B petrol 2.2 with same issue,even though i changed the spark plugs and coil pack!
Carry on my man🎉
quite a simple explanation of a complex problem, great video!
dan you are the MAN thank you for taking the pump apart and explaining how it works much appreciated
My pleasure!!
Dan is great at explaining the problem and how he gets through the diagnosis. Well done and thanks Dan! 🙏
Thank you James👍
graag gedaan
Enjoyed watching the disassembly of the fuel pump and finding the problem. Good fix.
Glad you liked it 👍
Absolutely brilliant!!! there's nobody else better to diagnose problems. love this channel! fantastic at teaching stuff in plain English too making everything 100% clear and very educational! a real hero
Wow thanks Ben i really appriciate your comment!!
I really enjoy your vids ,the humour, and the diag techniques. I have taken so much from your instruction, thank you for all the info you provide.
Good Fix. Always interesting to see a part taken apart and see why it failed.
Thanks for taking the time to leave a comment 👍
I really like Dan and his approach to his work, well done Dan. upload more videos i like watching videos of a professional like you.
What an excellent video Dan!!! Thank you, I love the way you teach while you take things apart!
Thank you Roxanne!!
Excellent diagnosis and explanation as usual. I’m curious why you did not repair the pump versus replace. Or parts not available?
I know very little about the GDI system, only what I've read.
My 2020 Toyota RAV4 with a 2.5L 4 cylinder has the GDI pump. It's not as noisy as some others I've heard, and performance is pretty good. Thank you for the explanation and diagnosis.
Now you know a little more😉
Such a joy watching this guy explaining stuff in a logical order! Great work, great channel!
Thanks alot!!!👍👍
I've got DI engine myself so this video is very helpful. You make it look so simple and explain very well. Keep it up man!
Very good explanation. I already learned a lot from your vids. Greetings from Germany
Dan, I look up to you as a technician, your videos are the best man! I got a job interview tomorrow wish me luck. 👍
Good luck!!!!!!👊
You know someone is good at what they are doing, if they make it look easy! Great diagnosis Dan. Jpol.
Wow thank you very much 😀
Good detective work and good repair. I hope I never meet one of those wobbly plate, 3 piston driven membrane high pressure fuel pumps.
Brilliant step by step diagnosis as always, pleasure to watch!
Good job!Hi from Russia! I watch all you videos. You telling about diagnostic very good !Thanks! Good luck!
Thank you!!!
