This has to be one of the most straightforward explanations of a VVT on the internet. Really good description of how it works. DIY mechanics shouldn't be fearful of tackiing this job. Thanks for sharing
Can't thank you enough. I hv been suffering with frequent CEL n limp mode for the last 3 months. No service centre nor "expert" mechanics could diagnose the cause (even with official scanning). Their conclusion was the ECU is kaput n i ought to buy a new one. After sumbling on to ur video today i opened and cleaned the turbo myself and the issue is fixed. THANK YOU.
By far, the best video explanation I've seen of how these turbos work and why they have issues. I was hoping the notchiness I felt in the actuator moving was from the actuator rod, unfortunately it's coming from the actuator lever on the turbo/vanes. After watching this, I'm way more confident cleaning the turbo. Thanks!
"LIMP MODE" I subscribed instantly after you explained that, I've been having the issue you describe on my Open/Vauxhall Signum 3.0 V6 CDTI 03, I'm a newbie to turbos and all the mechanics around here say don't touch it and buy a new one but I want to learn more about the unit and how to fix it myself, brilliant video, thank you
Personally, I would find a replacement out of a salvage yard. Then take that one apart and study it. Clean it and buy a rebuild kit. Then when you take your old one off you already know what you need to do. Good luck on that beauty!
Important to keep in mind: the turbo spins at over 120 thousand rpm, which is 2000 revs per second. A tiniest scratch, nick or bend on the turbine or compressor wheel will throw it out of balance, meaning reduced rpm of the turbo, and damaged turbo bearing.
I used Winns turbo cleaner spray. Sprayed a whole can in the turbo while the engine was on idling. Gave it 10 min took it for a spin and i can't believe it did the job. Easy cheap fix. And no service gave me this cheap option it was a last resort thing to see if it worked. They wanted me to recondition the turbo...car works fine now.
Extremely nice seeing this live with no animation. Even if you already know how VNT / VTG turbos / VGT work, it's great to really see this once. Thank you!
Perfect explanation and has given me the total insight as to why mine overboosts as with vacuum connected the turbo arm moves less than if I move it manually, and I can feel it dragging inside...now I understand why....brilliant explanation thanks!
Brilliant video. Answered my question where all other forums failed, and that is "there is no wastegate in these type of turbos". I have been searching for info on the Vito 111 cdi wastegate all week after reading on the Mercedes forum that this is the the reason my Vito keeps going into limp mode. The sticky actuator is for the variable vanes not the waste gate. I wish ill informed people would keep their mouths firmly shut !!
Thankyou, ive been suffering major overboost/limp mode issues, im not getting full travel on the vnt lever but i didn't understand whether up was open or closed, after watching this video i fully understand whats causing my problems.
A very good overview of VNT type turbo and potential fault points. Although Ive worked on a lot of cars over the last few decades this video was a good refresher on the VNT operation.
The Transit is the first Turbo I've owned with a VNT. I bought a new one and had it replaced, never knowing really what it did. The magic words here were 'a VNT system doesn't have a BOV" or something to that effect.
Superb explanation ... I'm a reasonably good home mechanic.. owning a mitsubishi L200...and didn't know exactly how these vanes work .... probably never take a turbo apart ...but it's nice to know how they operate... thanks
Super told. For the first time i had understand how it's work. Thank you. I have a issue with a overboost. I had mounted a gauge vacuum on the line to vaccum acuator. When i press the clutch i have a little to 90% vacuum and after small pitch the vacuum drop to 20 or 10. After 100km/h, i had limp mode with error overboost. It's seems that the vane are not clossing. The actuator moves ok, but as i understand from you, i can have that gap, that keeps the vanes open a little... Hmmm, i have to dismantle... In the summer i think... Thanks again...
Must admit that I have removed the exhaust flange and filled the housing with "Mr Muscle" oven cleaning foam. Left it for a couple of hours then cleaned out with brake cleaner and an air line. Next day, refitted flange and road test. Loads of black from exhaust but it does clear.
Excellent video. My Insignia has intermittent power loss and a P003A fault code. Basically, the car doesn't know where the vane position is and goes into fault, dumping the boost. Going to use Revive Turbo cleaner and see if it works out.
Hi there ,great informative video, thanks for posting it ,I have a honda crv deisel that go's into limp mode on hard acceleration, also there is a whistle coming from the turbo, I have been looking for a video that explains the workings of the turbo and now I will attempt to clean the veins. Many thanks Frank
Absolutely excellent video ................... very good usable information !! Now i know what is wrong with my 1.7 cdti Honda when it goes to the limp mode
At 13:09 the "control ring " is in upside down. The notch that the control lever sits in on the control ring sits between two holes. One is a "slot" and the other is a "round hole". The round hole should be on the left. I'm certain this will not allow correct amount of travel.
Brill video already been informed by main dealer I have a bad bog turbo among other things . This indicates the likely issue . One being likely lots of carbon build up .......I get noises only while driving its like a vibration (sound of ) buzzing hard to explain that happens more often snd less often at diff times ....maybe the vanes I'm not sure ..Great video indeed mazda mention they'd put a new turbo kit in and clean what they can . Iys removing ut that I'd not want to do as it's at the rear tucked away . A nightmare inc the oil feed
Hi, you r good, probably the best teacher. Fantastic information & clear video. Now i can put parts to words. Will also do some cleaning on mine. Greetings from the United Kingdom!!
One simpliest reason for limp mode is broken vacuum hose of turbo actuator. In some cars it's quite long line and can be broken where it's hard to notice.
I can see clearly now ! Great video man. How often should a vnt turbo be cleaned? i drive about an hour daily, defender td5 2.5 Turbotechnics VNT turbo.
Excellent explanation, well done. people scare you all the time to repair a Turbo ! But like everything else, Common Sense prevails.. Considering, Turbos rotate at a very high speed.
Hello. Nice video man, easy way to understand what's going on inside a turbocharger. Quick question... Why am I losing pressure through the hole where the actuator lever controls the control ring? This happens only when the vacuum hose is connected
I had problems with this type of turbocharger overspeeding and completely broke down on a engine in a man overboard boat after I don't know how many start/stop each Saturday routines onboard making the wastegate clogged with carbon deposits. I made a small device for the crew to be able to check if it's moving or not each Saturday and before launching the boat in the water in case of an emergency and crew gives full speed to avoid turbo breakdown again because of stuck wastegate. I was rewarded 3000$ for that simple device. Do you use to check movement as well or do you just wait for customers to come in with a turbo problem? Very good video but if I were you I would take off the gloves😊
Awesome video. I am buying a 2014 with tdi. As preventative maintenance i was looking into a rebuild kit for the turbo. Found many sites saying they are not rebuild able. Some said it takes special equipment to disassemble them. Finding parts may be tough but i see i can definitely disassemble it to inspect and clean. Look pretty easy. I have has variable geometry cummins turbos apart and this looks very different but not any more complicated at all. Is the nut on the compressor wheel left hand thread on these?
I agree very good video. I have a question I took mine apart to clean it. Then when I put the ring back on that has the veins on it and tighten the screws down the veins will not move. So I wonder if I am tightening them too tight should they be allowed to float a little bit.. if you could get back to me ASAP would be greatly appreciated.
Ive noticed the control ring wears away on these too, you can see the one in this video is worn where the actuator moves it, I guess this can also have some effect on the performance so I decided to replace mine when rebuilding.
But which way does the exhaust gas flow...is it through the vanes first and then onto the turbine wheel or is it the turbine wheel forst and then past the vanes ? I cant piece it together with the housing removed......no video yet has show this to me. Otherwise nice vid.....
Brilliant video I have this turbo on my fabia vrs Skoda, what could be wrong with the veins as it is pulling fine at low revs but is over boosting and going into limp mode at high revs and doesn’t have enough power after about 3000rpm I’ve had overboost diagnosed by a mechanic but he doesn’t know why it’s doing it, your video is excellent could it be a simple removal of exhaust pipe and spray oven cleaner in the exhaust side of the turbo? Many thanks in advance 👍🏼
But is there a way to fix the places that have worn down? The spots where levers have more play than they should, can anything be done to fix that or do you just have to get a new turbo?
Super video, and great eksplanation.. My 2001 vw passat, shows low boost error p1556. And got no turbo power bellow 28-3000 rpm, so it could be that the wanes are stuck at the non vacum position?? I think i havea look at the actuator and see if itmoves when vacuum aplied, how much should it move?? About 1 cm?? Cheers Johan
Really nice video, with lots of details. Can i ask you guys a question? I have a Renault Megane II with the 1.5DCI, 106cv. This has a variable geometry turbo. I had the car parked for a couple of months while i sorted some things out, and before parking it, the car worked OK. But now i just put it to run again (new brakes, new liquids, yadda yadda yadda...), and when i take it for a spin, there is absolutely no boost. No check engine lights or anything, but the car can barely make it to 80kp/h, and a slope almost kills it. I figure "maybe the vanes are sticking", and, stupid me, i drive the car in first and second gear to try and dislodge them. I succeed... or maybe not. There is boost now and the car is as quick as ever, but there is a "metallic" noise when spooling up and specially when comming off of boost, and if i leave the car idling for a minute, white smoke starts to build up. Did i just toas my turbo? is there any situation where the repair doesnt imply a new unit/total repair?
Thought this might be my problem, I have fault p1557 (charge pressure control : positive deviation) Goes into limp mode on high acceleration, switch off/on and fine again. 2008 1.9 tdi 115 Alhambra.
please help: I have a power loss for less than one second when passing thru some rpm range (~2000rpm) feels like all turbo pressure is lost and can hear some noise similar to a wastegate that release pressure. No errors, after this power loss, the car gain again the power and work fine. The most I feel this when I am on cruise control and car holds that problem rpm range... can the cause be this variable flow stuck? Did not known how VNT release extra pressure but now make sense since I was not able to found any other relief valve. thanks in advance for any advice :)
Hi, a quick question, I need to strip the Garrett turbo in my Land Rover because I think it is forcing oil into the exhaust system. I noticed some unusual white smoke at idle and also oil level dropped abnormally. The exhaust side has sticky sooth as well. It is a VNT?VGT retrofit. Would a standard core and seal kit work well or it would need to be a specially machined Core? Thanks
😮Omg... About 5 years ago I sprayed oven cleaner into the aluminum compressor side from under the car😅.. It's only now after watching this that I see the cleaner was no where near the carbon crab I wanted to clean😅😅. Still drive the car daily and had no troubles from spraying oven cleaner onto aluminium 😭🤔😀🙈

This has nothing to do with variable valve timing though...

Variable vane turbo ?
Can't thank you enough. I hv been suffering with frequent CEL n limp mode for the last 3 months. No service centre nor "expert" mechanics could diagnose the cause (even with official scanning). Their conclusion was the ECU is kaput n i ought to buy a new one.
After sumbling on to ur video today i opened and cleaned the turbo myself and the issue is fixed.
THANK YOU.
Watched the theory at 'Engineering explained' and came here to watch the practical. Bravo to both you guys! Excellent work...
Same thing !!! EE overhyped the explanation and i tough the vanes were in the compressor side .. this videos clearly explains and shows how it works !
By far, the best video explanation I've seen of how these turbos work and why they have issues. I was hoping the notchiness I felt in the actuator moving was from the actuator rod, unfortunately it's coming from the actuator lever on the turbo/vanes.

On which side of the turbo have you sprayed? Intake or exhaust? Did you leave it for 10 minutes at idle with the spray in? Thanks.

makes me want to go outside and take my turbo apart!! Nice video, well explained!
Navas Huskies that's what ill do this weekend thanks to this.
That’s exactly how I felt when I watched this. Ripped my turbo off yesterday going to take it apart today lol

If you are doing this yourself at home mark the oil inlet position on both housings before you take it apart, saves problems on reassembly.
Just recently found your videos whrn searchinh ingo about limp mode. Best detailed car videos :)
I just did this on my Saab 9-5 2007 and it works now. Thanks
A good video with clear explanations, it all makes sense. Getting at it is not so easy

great job. now i have understood what is\how it works a VNT turbo.
Needed this video!! Perfect video!! Just what I needed and helped me figure out that my vanes were stuck.
perfectly explained! Very usefull to limit my charging problems and check the functionality of my vacuum cell
Great vid thanks......gonna start pulling mine apart then clean with mr. muscle and finish with carb cleaner,hope it works.

Best video seen so far on this. Well explained and good lighten could see clearly. Play in control ring 👍
Another good video Chitty the forum has gone to crap since you have sold it, you link doesn't work now
Amazing video man.. you solved all my doubts about VNT turbos... And btw please make the video on how tthe solenoid works in This VNT mechanisms
Absolutely excellent video ................... very good usable information !! Now i know what is wrong with my 1.7 cdti Honda when it goes to the limp mode
Very clear and articulate explanation. Thanks for a very useful video.

Great video. Really glad I found this. Saved my ass and turbo.
Thanks a lot for this comprehensive video! What's the other opening on top of the exhaust manifold? Is it for the egr?
A clear and practical video. Thanks for the efforts!!
Hi, you r good, probably the best teacher. Fantastic information & clear video. Now i can put parts to words. Will also do some cleaning on mine. Greetings from the United Kingdom!!
Thanks bro love from Kenya 🇰🇪👍
One simpliest reason for limp mode is broken vacuum hose of turbo actuator. In some cars it's quite long line and can be broken where it's hard to notice.
FN amazing! I have a twin-turbo Mercedes and I will try to dial in both sides by using the adjustment nuts--if I can see them.
really excellent explanation, many thanks for helping me understand
Very informative video. Thanks a lot for your effort.
Very informative and beautifully presented.
Very well explained in depth. Subscribed! Any explanation on how to remove the turbo from the car? Thanks!
Audi A4 B7 TDI
I think the ring which moves vanes is put reverse at 180 gr. The small hole near external lever must put to the left side,not right side.
Where did you go man keep educating us bro
Excellent video pal.
What makes the Siren noise on a Turbo?
I can see clearly now ! Great video man. How often should a vnt turbo be cleaned? i drive about an hour daily, defender td5 2.5 Turbotechnics VNT turbo.
Thank you so much for this! Now it's down to sticky vains or rail pressure sensor causing me trouble.
Excellent explanation, well done. people scare you all the time to repair a Turbo ! But like everything else, Common Sense prevails.. Considering, Turbos rotate at a very high speed.
Awesome video man! Really detailed breakdown of the Turbo. Thanks 👍
Hello. Nice video man, easy way to understand what's going on inside a turbocharger. Quick question... Why am I losing pressure through the hole where the actuator lever controls the control ring? This happens only when the vacuum hose is connected

I put a $200 turbo in my TDI I’ve put 12K miles on it no problems. I just get limp mode very rarely.
Great video ! I have 2017 vw amarok bil turbo . Are both turbos looks like this ? And how often should I do maintenance?
I agree very good video. I have a question I took mine apart to clean it. Then when I put the ring back on that has the veins on it and tighten the screws down the veins will not move. So I wonder if I am tightening them too tight should they be allowed to float a little bit.. if you could get back to me ASAP would be greatly appreciated.
Adjusting the stop screw - how do I know where to set it? Is there a spec for the clearance between vanes? Thanks, awesome video!
A very clear explenation. Well done
Wow this is the real video which i was searching for... 👍🏼
thanks i been clean a few turbo all is done well
Is the control ring made out of brass? Thanks and great video.
Thanks for all this informations . Keep the good work
Ive noticed the control ring wears away on these too, you can see the one in this video is worn where the actuator moves it, I guess this can also have some effect on the performance so I decided to replace mine when rebuilding.
where did you source the control ring, and do you have a part number?
@@MikeEwart-w5n I’m not sure if oem replacements are available I found a kit on eBay
Very clear thank you for sharing
But which way does the exhaust gas flow...is it through the vanes first and then onto the turbine wheel or is it the turbine wheel forst and then past the vanes ? I cant piece it together with the housing removed......no video yet has show this to me. Otherwise nice vid.....
Best video I've seen
Brilliant video I have this turbo on my fabia vrs Skoda, what could be wrong with the veins as it is pulling fine at low revs but is over boosting and going into limp mode at high revs and doesn’t have enough power after about 3000rpm I’ve had overboost diagnosed by a mechanic but he doesn’t know why it’s doing it, your video is excellent could it be a simple removal of exhaust pipe and spray oven cleaner in the exhaust side of the turbo?

Vanes are jammed. Remove, dismantle and clean.
Well explained👍

But is there a way to fix the places that have worn down? The spots where levers have more play than they should, can anything be done to fix that or do you just have to get a new turbo?
Briliant ! THANKS A MILLION
Super video, and great eksplanation..
My 2001 vw passat, shows low boost error p1556. And got no turbo power bellow 28-3000 rpm, so it could be that the wanes are stuck at the non vacum position??
I think i havea look at the actuator and see if itmoves when vacuum aplied, how much should it move?? About 1 cm??
Cheers

Very informative video, i might have a faulty turbo...
so are they any different between the vgt and vnt besides the vance inside are boosted the same principle
thanks for the video man. SUBSCRIBED
Really nice video, with lots of details. Can i ask you guys a question? I have a Renault Megane II with the 1.5DCI, 106cv. This has a variable geometry turbo.
I had the car parked for a couple of months while i sorted some things out, and before parking it, the car worked OK. But now i just put it to run again (new brakes, new liquids, yadda yadda yadda...), and when i take it for a spin, there is absolutely no boost. No check engine lights or anything, but the car can barely make it to 80kp/h, and a slope almost kills it. I figure "maybe the vanes are sticking", and, stupid me, i drive the car in first and second gear to try and dislodge them. I succeed... or maybe not. There is boost now and the car is as quick as ever, but there is a "metallic" noise when spooling up and specially when comming off of boost, and if i leave the car idling for a minute, white smoke starts to build up.
Did i just toas my turbo? is there any situation where the repair doesnt imply a new unit/total repair?
Very useful knowkedge
Can I use carb cleaner on the cold side (just past air box)
And oven cleaner exhaust side to clean?
Thought this might be my problem, I have fault p1557 (charge pressure control : positive deviation)
Goes into limp mode on high acceleration, switch off/on and fine again. 2008 1.9 tdi 115 Alhambra.

Hi, a quick question, I need to strip the Garrett turbo in my Land Rover because I think it is forcing oil into the exhaust system. I noticed some unusual white smoke at idle and also oil level dropped abnormally. The exhaust side has sticky sooth as well. It is a VNT?VGT retrofit. Would a standard core and seal kit work well or it would need to be a specially machined Core? Thanks
Here's a question... Can veins become sticky on petrol turbos?
😮Omg...
About 5 years ago I sprayed oven cleaner into the aluminum compressor side from under the car😅..
It's only now after watching this that I see the cleaner was no where near the carbon crab I wanted to clean😅😅.
Still drive the car daily and had no troubles from spraying oven cleaner onto aluminium 😭🤔😀🙈
