You cant imagine that because most of the clients are not like this one 😉 ( every client deserves their mechanic)

They are honest but not that good.

We could all be a lot better if Europe wasn’t such an unhelpful area at forcing the manufacturers to give us proper wiring information and systems education. The Americans have Mitchel wiring diagrams-what do we have -Autodata that is (a)unviably priced for most small garages and (b) often incomplete and unreliable on individual cars and doesn’t even cover many common cars and not all systems on the ones it does cover. The trade is a shambles and it’s the public that are suffering because of the poor governance of manufacturers

The world could not afford every mechanic to be this good

The crooked ones don't like techs like Dan and plus they show it on video. How can they make money??These dishonest ones cause the honest and knowledgeable ones not to charge fairly .

they don't come fast enough lol

​@@Bizija123 That's why you're looking forward for the next episode 😇.

Quality over quantity! That is why every episode is fascinating and captivating.

That's great to hear!

Thank you

👌

the Dutch AA ANWB is well equiped and educated.

@@arjanvanraaij8440 Yes we are 😁

I agree and have great respect for the roadside assistance, they do amazing things with limited resources

Should he not have noticed the obvious hydraulic lock issue.

The sound is familiar, and i'm sure the mechanic on the side of the road thought the same, but to pinpoint the issue exactly is impossible without tools, a fuel issue can be caused by a wide range of components, thinking it is a fuel issue because it sounds like it wants to start but can't is just not that useful. i think using a scope to test battery drain when there's an injector stuck open is genius!

Thanks for your help, i couldn't have done it without you!😉

@@Diagnosedan you did it without him!

A skip like that in a diesel could be different things. Bent valve, hole in piston, but in the common rail diesel, always start with fuel. It's not going to be a spark plug

Thank you

There's far better ways to do this.

He cranked it for way longer than necessary to confirm it was a bad injector.

@@michaelgleason4791 how ? btw , if the injector are plugged to test the injectors , why there isn't any diesel coming out from all cylinders ?

@@DanidasanicOther 5 injectors cant spray any fuel because there is low pressure on rail. Diesel smoke comes from faulty cylinder is only diesel puddle at the bottom of cylinder 2 sprayed through glowplug hole

@@Danidasanic There was diesel coming out of all the cylinders, look closer. Obviously far more from cylinder 2.

We got the approval to check the other injectors👍

True.

Relative compression test done on starter current (as shown by Dan) but with crank shaft sensor signal as a reference to get cyl #1 and taking into account firing order of the engine would show the drastic imbalance on the screen of a diagnostics tool that can be read no matter how noisy the environment is. And would have identified the disfunctional cylinder with much less work on disassembly. This is like instrument flight instead of visual flight. In addition, notice the heavy physical distortions and shaking that this engine makes due to the open injector. From the video alone, it hurts my senses, when the cranking is done over and over on this engine. I'm with you: diagnostics at the road side is way more difficult, due to weather (rain, cold) and outside noise and limited gear, tools and parts, that can be taken to the place. But to identify the misfiring injector, block it with a small screw (a nice trick shown by Dan!), document the work, and have the client continue his (hopefully short) journey on 5 cylinders of this V6 TDI engine would have been possible at the roadside. And then to ask the client to drive to a workshop at the next possible option in time, like the next day.

@@koeniglicher yes a quick and simple check non-invasive and gives direction i was going to say myself

True

@@koeniglicher So if he continued to drive it with oil dilution and it ran a bearing or worse yet "took off" the roadside tech would still have got the blame. He was in a no win situation. We do not carry a scope or have the ability to do a relative compression test. We all probably heard it was cranking odd and to be honest he should have just stopped there and got it towed to a workshop for further diagnosis end of story. People need to distinguish between emergency breakdown service and mobile workshop ! Two completely different things. People always look for someone else to pay for there repairs these day's , sadly my job has more become "what am I going to get blamed for" rather than "what can I do to help". 🙂

Fuel pressure was low I guess due to the leaky injector so not all bad. But defo always start your way. Don’t be led down a rabbit hole by someone else’s info. But yep agree with you

No guess the injector was leaking a common problem on common rail systems not that hard to diagnose

Thanks!

Thank you

I was going to say the same. Simple but effective

Did he take it out?

@@ppal64 Yes, he did after installing the new injector.

A ball bearing is good too.

Old trick😉 although there are blanks available to close the rail

You are right in most cases we see a cilinder with less compression not more!

I think it was a current spike, not voltage spike.

Thr amount of people that I have seen throwing thousands in parts at such simple issues, especially in a DYI setting, is painful. Especially if you know that more often than not they end up causing more damage by working without the necessary cleanliness for these injection systems...

Err no we wouldn’t

Thanks for watching

Thanks!

Thanks Pedro!

Thats programmed into the ecu as a Deep clean fuel flush crankcase regen

would be interesting 🙂

my thinking too. poor rod, I was wincing with pain seeing the amp current peak out!

@@StationGarageSt one thing is the starter, but this happened while driving 😳

@@MC-Racing even more wincing? I'm blaming Mr McPiezo-Crystalface No2 for letting the side down. All his mates stayed true to the cause. He Spoils the party 'cos he just won't shut up!

There is no need to do a test again when the engine is running even on all cylinders

On this engine the hpfp is not an easy job! I'm glad it was an injector🤣

@@Diagnosedan a couple of weeks after watching this my stepson had poor starting on his Skoda Rapid 1.4tdi. It turned out to be contaminated fuel however despite a clean tank and filter the problem continued. Fearing it was an injector issue similar to this it had to go to the dealer. I was blown away when the fixed it with this Volkswagen additive part number G001790M3 which they used after guided fault finding. Symptom poor starting and running when cold, no fault code stored

Thanks for watching

Thanks Mark, great to hear that you liked the video

Have faith😉

The diesel injectors on this model were not that bad indeed but i can assure you that isnt always the case! On some models they can become VERY stuck!

Or the one screaming in to the camera.

Are you cussing south main auto or scanner danner? How dare you.

Thanks for the positive comment its appriciated 👍

We got the approval to test the other injectors 👍

Thanks for the positive feedback

Thanks!

That's also a good idea, but a screw is easy to find

Thanks Steve

The washer between the injector and the cilinderhead gets crushed over time and the injector starts to get a little play. This causes vibrations and that causes the injector to fail. The new injector has an updated washer.

It was the opposite, high compression 😁😉

Thanks Greg

para cuando un video???

Not in this case, the seal between the cilinderhead and the injector crushes over time. This causes the injector to get some room to move and vibrate. This damages the injectors. I've removed the other injectors and tested them. No other injector needed to be replaced. One injector seal failed and we were just in time to safe that injector.

Thank you Mark

🤣🤣👍

🤣🤣👍

the sound of a 5 cilinder diesel is great.

🤣🤣👍

also in the VW 2.5L transporter/multivan , although I thought it was a Volvo block (with a VW head).

300TD of Mercedes too.

It could have been diagnosed in many different ways that lead to the same outcome

Also can occur if the owner put truck or agricultural diesel in, because that is high sulphur, and not great for the precision parts of the fuel system. Similar if you run illuminating paraffin or heating oil, or recycled cooking oil that has been sold as biodiesel.

No i didn't check because i know why these injectors fail.

@@Diagnosedan Congratulations, you understand everything from mechanics to electricity, it's so nice to learn from people like you

Do you do the same as Dan did with the ball bearing ( i know Dan used a screw instead)and reconnect the fuel line to injector and reconnect the wiring connector to injector when you do the test.cheers.

Never tried a ball bearing but i guess it works, i think a screw is more randomly available.

Thanks Glen, its appriciated as always!

Great!

these are actually very high pressure 20,000 psi piezo- quartz electric injectors controlled by the ECU

Thanks!

🤣🤣🤣 tell your wife i'm sorry for borrowing you sometimes to help me diagnose the problem 😉

Thanks as always

Great!

@@Diagnosedan Hey Dan, did you have formal education like automotive engineering or it is something you picked up by yourself? Want to find more similarities between us...😀

Thank you Andy

Merci!

Thank you

Thank you!

Thanks Derek

Awesome!

Thank you very much

Thanks!

Yes i screw is always available

Awsome guess 👍👍

Thank you very much sir!

Thanks for the great comment Mark

Thanks John

Thanks!

Ha ha thanks

Thanks John

My pleasure

Thanks!

Thank you

Thanks for the comment

Thank you sir

Thanks!

Hi Nico, its a pleasure to hear you learned something from this video!

You are right, use all your senses

I'm never worried unless its my own car🤣🤣🤣

@@Diagnosedan LOL 🤣

Thank you

My pleasure
