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.
😊 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.
😂 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…
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
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.
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. ;-)
We missed you Dan....! Thanks again for the excellent diagnostic lesson. Always amazing and educational. Nobody does it like you do. Thanks again Professor..
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 👍
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.
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 TH-cam🤝🏻
When I worked in the shop or on the shop I would tell the customer. That'll be charged two charges. And the second thing I need to tell him is that nine times out of 10 is one spaghetti nut mess. So it's like I'm doing their stuff and then doing the right stuff just like you God bless you ❤
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!
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.
Good research and repair process. Also, NO colatteral damage and a cleaned engine that removed all "finger prints etc". Customer should get some refunds from the other shop too.
Your the man Dan. I just fixed/repaired my first BMW. No crank, no start.don't have a scanner that can talk to the BMW, so I had to relye on utub. Did a bypass on the immobilizer to verify that the starter worked. Then found fuse #30 was blowing. Utub to the rescue, said check out the oil sensor level sensor. Found a wire bare at the 90• coming out of the sensor. Tape it up, did not reconnect to the sensor, costomer request.the car is no😅 doing fine. 325ci.
Pico for the win, proving the problem. When I saw that up rise point in the waveform even with my limited Pico knowledge, immediately I said exhaust valve and timing chain problem. In school we learned 2.54 centimeters or 25.4 milimeters equaled 1 inch. In engine timing THAT'S A LOT! No wonder that poor little engine with a 24 milimeter stretched timing chain couldn't move that car! Well they brought it to the right guy who fixed it. Good one Dan!
Forget about inches 🤣 only 1 country in the world using those😁 thanks for leaving a comment Mike it's really appreciated. On my Facebook page i've got a picture of the old vs New chain.
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.
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.

Superb diagnosis once again Dan, don’t know why they would send their car to another shop when they could go directly to the genius that is Dan, keep posting I love watching you diagnose 😊
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!
Nice one Dan , I've just done today a peugeot 1.2 puretech 3 cylinder timing belt kit , only 38000 miles , 2019 car , 1st problem no oil pressure , reason belt fibres blocking oil pump pickup , (just as Ford ecoboom ) engine , both are wetbelt systems , absolute junk , rubber does not like oil , I removed the sump , cleaned the pickup , refitted the cleaned sump , new correct grade oil 0w20 ( like cooking oil ) and genuine oil filter , now car has oil pressure, so then replaced genuine belt kit ,crank seal and bolts, job fixed , regular servicing helps Mr customer , here is my as per quote expensive invoice 👍
The problem is not that the belt doesn't like oil. A little amount of petrol makes it into the engine oil. Its the petrol that the belt doesn't like. More frequent oil changes can prevent a lot of issues.
For a quick old school test , I believe using a vacuum gauge , would show between 8 to 15 lbs. for late valve timing . It certainly would not hurt to confirm the results with a more advanced test . However , it may point you in the direction . Unfortunately , since all modern engines don't have easily found marks , distributors or easily removable valve covers , it becomes involved . You can look at the valves with a bore scope , but getting reference marks may be difficult . Sometimes removing a #1 plug is a project . Great diagnosis and fix .
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.

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!
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
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 👍🏻

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
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. 🤫
This is incredible. VW switched from timing belts to timing chains but kept the same lifespan.
Thats about right😂
Brilliant detective work.
Thank you!
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.
1.2 engine is a Big Block today's scale 😀 Good diagnosing again!
🤣🤣👍
Hello Dan, we've been waiting for your videos. Kindly if you can make these videos often. Appreciate.

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👍
Nice demonstration and proof of concept testing in order to hit the nail on the head and not guess! Thank you for sharing with us as always!

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.......🫣

let´s see if I guess it right, I'm at minute 1 and my guess is a clogged cat. WOW I was wrong. You sir are the best at diagnosing every engine!
Thanks for watching!
I was impressed with how much room there was to work on the chain, that's a gift!
Only a small 3 cilinder engine😉
When I worked in the shop or on the shop I would tell the customer. That'll be charged two charges. And the second thing I need to tell him is that nine times out of 10 is one spaghetti nut mess. So it's like I'm doing their stuff and then doing the right stuff just like you God bless you ❤
Thanks for watching!
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.
2012 and it’s repairable is a miracle for a VW.
Economically*
At that driven distance it's past designated lifetime.
Its always repairable 😉
The complete timing chain kit as shown costs 140 Euros. Dirt cheap
@@ehsnils Plenty for sale in Denmark with over 200 k km, some near 300 k
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!
Thanks for the feedback!
Great video. I like those dividers that show the TDC and BDC so you can see the degrees.
Awesome diagnosis again Dan 👌👏👏👏
Thank you
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
Another great troubleshooting, you never disappoint 😊
Thank you!!!
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 👍
Good research and repair process. Also, NO colatteral damage and a cleaned engine that removed all "finger prints etc". Customer should get some refunds from the other shop too.
Removed all evidence 🤣🤣
Great job, Thank you Dan for explaining EVERYTHING and re-doing those tests!
Its a pleasure
A beautiful diagnostic Dany 😎👍✅✅✅✅
Thanks!!!
Thanks Dan for explaining a bit more about in cylinder danusures and how to 5est for street time chains
Thanks for watching!

"is Automatically changed"? 😅
