Very interesting diagnosis as always. I’m trying to understand how a loose chain would cause timing to advance. Wouldn’t skipping a tooth cause timing to be retarded thus causing the exhaust valve to close later rather than sooner? Could it be that the pressure bump is caused by the intake valve opening too late? I believe I read somewhere that some engines send a brief pressure pulse into the intake runner to create a shock wave in order to improve cylinder filling during the intake stroke. Thank you.
@@frankp.2831I'm interested to hear the answer for this question too and also how much longer that old chain was compared to new one? Great video as always👍🏼
Not hard at all. Every rise on the waveform indicates a rise in pressure. That little hump was in an area where it should've remained level. Meaning that the piston was on its way up when the exhaust valve closed a little to soon
@@frnkjones40 But, no one else was able to explain it in such a clear concise way - I watched other videos and was not clear on exactly what to look for. This was excellent... Dan's approach makes it so much more digestible.
@@Diagnosedan Don't sell yourself short - it's easy for you now, but first time you come across it, you need someone who can explain the concept clearly - I have not seen anyone else do a good a job at it as you have.
Great to see you again sir !!! - This is a VERY COMMON issue here in the US with Audi. I always use the CMP / CKP Sensor Correlation data and waveform as my initial assessment with that code.
😂 always appreciate your work. I can honestly say that I don’t know of any channel that does such a complete presentation on vehicle electronics. Plus the bloopers are an added bonus…
😊 thank you for another wonderful video. Thank you for giving us the extra knowledge of trying to diagnose the vehicle with the proper tools 10 out of 10.
It's a rainy, miserable day and I was bored out of my tree, so it was perfect " timing " that you just loaded this video. As you said this was not an exhausting task at all. Cheers from Canada
Nice to see you back Dan. These engines are very prone to timing chain slipping if the engine is turned over backwards. Not a good thing if you park in a forward gear facing up hill. ;-)
Kudos to Dan...two things: 1) when scan tools first came out, very few mechanics could look at a waveform and understand what it was trying to tell them. That second pressure hump pointed a big finger at the problem. 2) It would have been nice to see the old chain stretched out next to the new one on the table. Amazing that a tiny bit of wear on each link would add up to so much stretch.
I've been looking forward to your new video! I thought ahead about how to discover if the chain was stretched, but had no idea about this method. Very enlightening. Thanks, Dan. Your videos are invaluable.
We missed you Dan....! Thanks again for the excellent diagnostic lesson. Always amazing and educational. Nobody does it like you do. Thanks again Professor..
Dan looking like he's on a good health regime - slim and trim. You would think that car manufacturers would have a timing chain sensor to alert the driver with a Check Engine light when the chain guides pass their maximum tension measurement. That would save on a lot of diagnostics!
Thank you for creating such great content. You are not just an excellent technician but a great teacher as well. I bet you learn even more after teaching us on UA-cam🤝🏻
Those polos with the 1,2 are notorious for stretching chains, I knew instantly that it would be stretched chain when I saw it. I tend to advice people to stick to the 1,4 four cylinder engine instead as it uses a timing belt instead of chain and is overall quite reliable, the belt is also easy to change DIY. On top of that it uses about the same amount of fuel as it isn't as labored as the 1,2. Would be interesting if you could show the maintenance history of the car (or lack thereof) as it's a major contributor to stretched timing chains, even still VW are notorious for making bad quality timing chains so I wouldn't be surprised if the car had good service history.
We dont always have the service history available on older cars that have been serviced elsewhere. There was no service book in the car and no digital records
I love all your vids Dan, they have taught me alot. But on this one I don't understand why you reached for all the sexy toys when a quick removal of the camshaft end caps would have revealed the grooves on the shaft ends not lining up. Or have I missed something? Keep up the great work!
Yes let me explain the point of the video. I work on all brands, all engines, this method is universal for all engines. Generally timing an engine mechanicly requires quite some disasambly. And you need timing tools for all makes and models even when you might not need them. This method is fast on all engines 3-6-8 or 12 cilinders doesn't matter.
Appreciate all your videos. By the way I’m on my second year of subscription to DD tsb. Absolutely first class.It’s got me out of trouble so many times 👍
Whatever you've done in the edit with regards to noise cancelling the engine but at the same time maintaining clear commentary is second to none. So good I nearly didn't notice!
I did same job last year on a Polo, not understand how they built such a good quality engine with that tiny chain instead of a bigger one or a good belt. Luckily the harder part of the job is about sealing and getting access to some bolts...
It was special again. I watched it with great interest. You remain a specialist. Thanks for this episode and I'm eagerly awaiting the next one. Het was weer speciaal. Ik heb er met veel belangstelling naar gekeken. Je blijft een specialist. Bedankt voor deze aflevering en ik kijk met belangstelling uit naat de volgende. Groet Arie.
The super charger seems to be the thing that's making the most whiny noise. Can you check it's lube levels easily? Someone's going to love that 3.2 in the summer, it's the best time to sell them anyway so don't give up on it. You've earnt the right to have some top down fun with it yourself.
Than you Dan for sharing valuable information with us! We have VW dealers that are not this good in diagnosing as you and are more keen on stealing, what a shame.
Yeaaaah! Havent seen the video yet, but I am sure this one is as awesome as the others. So it's a thumbs up and comment from me before I watch. Keep it up mate!
Great bit of diagnosing as usual Dan! I still say I believe that simplex chains are just not man enough to last the life of an engine, even a baby one like this! Duplex FTW!😂
I'd be curious to know what parts the other shop mistakenly replaced. There are so many cases where another shop completely misdiagnosed a problem and replaced and billed for parts that did not need to be replaced.
I remember that little exhaust stroke hump from one of the BMW vanos videos. That time timing chain was not the issue though. Keep up the good work Dan.
Love your in-depth diagnostics. These days it's hard to locate a shop that will take the time to do it correctly. Also like your bloopers. Funny Dude!!!
Hi Dan, thank you so much for sharing your knowledge. We are learning free from you. I hope the other mechanic are honest like your. Some are scary just two absorber shock front for Volkswagen Caddy 2010 model he is charging me $1600 then camshaft assy with timing belt kit worth $5500 too much.
Thank you Dan for another amazing video. You've got to wonder how these cowboy shops are allowed to stay open. They should all be shut down to protect the public from rogue traders.

Nothing Excites Me More In Life Then Receiving A Notification That DiagnoseDan Uploaded A Video 😊
You need to get out more.
Every year 😂
The bell doesnt work for me :(
😂. I understand. He's very good at explaining even to a newbie. Some other channels already assume you know the basics.
Thats great to hear, next video comes sooner!
How do you make an advanced concept so easy to understand? It must be a gift.
Its not complicated, if it was i wouldn't understand it either😂
I agree, he explains it better than a college instructor ever could 👍🏻

This is a good lesson for workshops. If you guess the problem then you will lose customers even though the guess was correct!
Thats right
This is incredible. VW switched from timing belts to timing chains but kept the same lifespan.
Thats about right😂
I just finished watching Pine Hollow Auto Diagnostic video and now i'm here , keep up the good work.
Me too!
And me
same here
lol Me too !
Watch Wes Work too
Brilliant detective work.
Thank you!
Hello Dan, we've been waiting for your videos. Kindly if you can make these videos often. Appreciate.
Next one coming sooner!
Keep the videos coming, we love them.
DD's videos are solid gold!
Thank you very much thats appreciated!
Always fun watching Dan properly diagnose these failures. I learn more every time. 👍🏻
Thats great!
Yep its obvious don't buy a German car. Problem fixed.

I was impressed with how much room there was to work on the chain, that's a gift!
Only a small 3 cilinder engine😉
Thanks to your skill and professionalism, now we have everything a customer should want from a mechanic.

Dan! This was a perfect opportunity to use the PHAD Pressure Transducer kit that I sent you! 😉
Holy crap that chain was STRETCHED!! 😮
Hi Ivan.....next time😉👍😘
It was worth it to wait so long for the next video, enjoy

Nice to see you back Dan.
These engines are very prone to timing chain slipping if the engine is turned over backwards. Not a good thing if you park in a forward gear facing up hill. ;-)
Or a reverse gear facing down hill lol
You are right, i've also seen cases that they rotated the engine the wrong way during a clutch job.......🫣

Another great diag - you are the Femke Bol of car diagnostics !
She's faster😂
Real nice to get another video from Dan. That timing chain was so stretched it must be made from plastic.
The chain on the 1.2 is actually made from liquorice. 😁
I've got photos of the chain on my Facebook page 👍
Great video.waiting for more videos
Great video, Dan. Lovely to see you back again! 😆
Thanks!!
Another great troubleshooting, you never disappoint 😊

Fanbloodytastic diagnosis Dan you are the man 👍🇬🇧
Thanks!
Has no power? That's how it was made...
😂😂
And guzzles gas compared to modern engines 😢
😂😂😂😂😂😂
Yes, this isn't the WRC rally version... 😆😆😆
With a worn chain it has less than no power. 🤫
First video for this year, well done Dan.
Sorry little late🤣
You have a very good videos Dan, the owner should know that the chain is automatically changed between 120 - 150 thousand km.
"is Automatically changed"? 😅
yeah it does it itself, very smart car@@rkan2
bloody good show , as always awesome viewing, cheers
Thank you Robbert
Thanks for taking the time to show us the waveforms after repair, Dan! We realize that takes expensive time for you to do that. Love you, man!
I like to confirm my repair anyway so might just as well show it👍
Dan The Man. I'm always excited when I see you have posted a new video. Can you maby show us the repair next time?

Excellente vidéo comme à ton habitude Dan
Thanks!
I would liked to see you change the parts, can you also do a shop tour? Thanks 👍
I liked that there was info on what the specs were for the timing chain tensioner! That would be handy.
Yes indeed, at DDTSB we like to include as much information as we can.
Great video Dan im always learning new things from you God bless
Thanks!
Than you Dan for sharing valuable information with us! We have VW dealers that are not this good in diagnosing as you and are more keen on stealing, what a shame.
Remember there are also great Dealerships out there
I'm amazed they didn't try the chains first. That's really the only common fault on that particular engine except for coils.
Dont try but measure😉
@@Diagnosedan 100%, but the majority of mechanics will go for the most likely solution instead of a proper diagnosis.
As always Dan excellent video on start to finnish to problem do wish that you could do more videos .
