Hi
This 2008 Vauxhall Astra 1.9 CDTI, with the engine Z19DTH, came to me after being scanned by someone else, with an "air leak detected" fault code... more specifically P2279
A bit of investigation and problem found!
Follow me on this video to find out what was the problem and how to resolve it.

![[Z19DTH] Replace Inlet Manifold and Timing Belt 4K](http://i.ytimg.com/vi/Rr2yr8pudMU/mqdefault.jpg)
I did this to my opel vectra C 1.9cdti 150hp about three years ago. And yes it was the best option removing the four windows and blanking out the top holes on the manfold. Allso cleaning all the carbom build up that it had. EGR valve, throtle body, and sensor. Now it drives so good again. Thanks for up loading Mr......Richi .....Islas....canarias....

@@LMAutoRepairs De nada amigo saludos.......
Good job don't need stupid flaps in the first place good video showing what's involved
Agree!
👍👍👍
Great work, mechanics are the new doctors
😊
Thanks!
👍👍👍
thank you for the knowledge you give me with your videos
😊
👍👍👍
Great video I had the same issue with a vectra intake manifold plastic linkage snapped common issue
😊
👍👍👍
Another job well done and an enjoyable video to watch.
Thank you!
👍👍👍
Another great diagnosis and repair 👍
😊
Thanks!
👍👍👍
YouDid not need to take off the cam belt On the front of the diesel pulley there is two holes if you turn the crank round there is two threaded holes in the back plate which you can just go onto which leaves the pulley and belt in the correct position
😊
👍👍👍
Very Interesting I would be too nervous to touch timing belt 😬 nice food review at end
😋
👍👍👍
Nice use of the propane can Luis.. What could possibly go wrong! Great stuff as always.
Propane?
😊
Thank you for watching and for your comment!
HAHAHHAHAAH
The cluster its difrent from opel vectra c of same model , but i have the opc line type, very good to drive , its litle easyer to replement glowplugs at that engine thant DT engine, if you want a engine to start it bettet replement the glowplugs , fuelflter , and clean the fuelesystem with Tunap 989
Good luck
Good job👍Thanks for video!
😊
Thanks!

This is going to sound weird. I have never removed and plugged swirl flaps.Changed a lot of inlet manifolds yes, MB, BMW, Chrysler, Opel and so forth. I have suggested it to clients and to my surprise they always go with the manifold. Normally they bite 25 cents in half and I even tell them that the car will drive the same. Strange world. Nice one Luis.
😊
Both BMWs I had, I removed the flaps...
And my fist one, was fitted with the metal ones...😬
👍👍👍
Cool video!!! Thanks for sharing!!!

Realy good video showing from dianose problem to fixing it , I have a astra h tdi 07 plate I had a similar problem 3 or 4 years ago limp mode when turbo come in at 3 to 5 rpm intermittent I fixed it ,I tryed every thing clean map sensor replaced maf sensor I not a mercanic just keen on diy fixing my own car. Iv just subscribed to your channal . Question If you delete the swell flaps will it not pass mot emissions test ? What stuff did you use to clean carbon out of intake ? Thanks lee
The flaps will make a negligible difference on the emissions... you don't need to worry...
I first scrape the carbon away...
And then use diluent with rags, brushes, etc...
Diluent can eat certain plastics, so you need to be careful...
There is other cleaning substances, like dgreaser etc... if you want to try those...
👍👍👍
I have a vauxhall Antara with a swirl flaps issue is this likely to be the same problem.
Superb👍
Great video Bro, love the repair process, one question I've is how do you time the high pressure pump, I mean do you use a timing light for that purpose or is it fixed?
Thanks for sharing Bro, Stay Safe😍
Common rail pumps are not stncronized... they are just that, a pump...
They buil ld the fuel pressure...
👍👍👍👍
@@LMAutoRepairs Great information, Thanks Bro😍
bom dia e bom domingo irmao luis😊

شكراً جزيلا لك أخي . أنت رائع
شكرا لاذع وتعليقك!
you need to add some ice cream to them strawbs
😋
👍👍👍
What can .make the pump underneath the back seat on a vectra 1.9 150bhp 110kw Z19DTH face lift .make a bubbling gurgaling sound when it switch on . Iv changed the pump the center conecter in-between the fuel lins is open .thetes no pipe there is it possible theres one there but pushed between the body and tank .as theres no pip on the inside of the pump there
Wish I had seen a video of this fault 7 yrs ago. I had no end of trouble with that code and limp mode on a Saab 93. I ended up scrapping the car because it was driving me insane not being able to find the leak (I didn't haave a smole machine:(
😊
At least now you know...😉
👍👍👍
Hi is there anyway to message you a video clip of my steering wheel jolting for some advice please,had the problem 2yrs and seems knobody knos whats wrong.thanks
Thank you.
👍👍👍
How can I contact you? I have U0129 code on a 2014 C1 that 2 garages have failed to diagnose 😅
Ho mate am avin the same problem how did u charge the customer if u dnt mind plz
Manifoldu söküp yeni girdapları taksak olurmu, sizin yaptığınız gibi yaparsak motor ömrüne etki edermi yada yakıta, bu girdapların asıl amacı nedir
Good video mate but you could of locked the fuel pump with 2 screws what hold the cambelt cover so you wouldn’t have to undo the timing but still great video
☺️
👍👍👍
Hi love all the videos. Can I ask a question please. Removing the inlet manifold from the astra H the threaded bar that holds the fuel pump on. You had to remove one of these threaded bar to remove the manifold. You put two nuts onto the bar to then get a socket on to remove. Can you tell me what size the nuts were as I'm considering doing this same work to my astra H
Hi
Just two normal nuts with the same thread...
Nothing special...🤪
👍👍👍
Amazing 👌🏻😇👍🏻
😊
👍👍👍
hi LM autorepairs! can i replace a bad ECU on a astra 1.7cdti with another second hand one,without programming? what else should i need to replace as all system to work as it should do?(transponder,key transponder,cluster,etc?). i mean if i will replace all those car modules on my car,with others from a doner car ,would my car work as it should ??? start engine,remote locks,aircon,etc..? thx!
Already replied...
👍👍👍
a comparison of MPG before and after would be great
Would have been probably interesting... i would predict that would be negligible though...
Thank you for watching!
A bit better boost .but not a lot
Not really big difference to tell the true...i was driving witj swirl flap rail out,there was a holes in 3 of them,since I fixed it and sealed the holes there was only a slight difference in fuel economy and bit better boost but not massive diference
Great job where are you based 👍
I hate them swirl flaps.... and hate more taking them manifold out. , I don't mind welding up the holes 😁
😅
👍👍👍
Thanks for the video, where did you buy those grooved plugs?
eBay if I recall correctly...
👍👍👍
Pls I need your help I have Fiat panda 2015 1.3jtd with DPF 23000km but it make blue smoke when I go slowly extremely to much blue smoke
Hi
Blue smoke often means it is burning oil...
Which often is leaked by the turbo... I would start by checking that...
👍👍👍
U can remove fuel pump and leave time belt and gear in
Place..that’s if u are not replacing timing belt when doing the job..
He did not touch the timing belt tensioner so it doesn't matter. But yes, it is done this way you described so you don't need to mess with timing if you are not changing the belt. Sad thing that owner did not want to change the belt at this state. As this car is probably from auction and for reselling it is done very well. Great job Louis.
Thanks guys!
👍👍👍
Nice job Luis. By the way if you don't mind me asking Luis what's your day job.
Thanks!
Nothing to do with cars...😊
👍👍👍
Support is not a Crime

What did you used to clean that sensor? Great video mate👍😉
Contact cleaner spray...
It "washes" and dry quickly...
👍👍👍
@@LMAutoRepairs awsome, thx mate
Coincidence, had same code on one last week. It had eaten it's flaps. Code only appeared after what was left of flaps removed and flaps were mapped out of ECU. Obviously not done quite right.
On another note, could I ask if you have done a video comparing your 908 v 608 with regards to just their diagnostic functionality. It's getting to the time when I could do with another machine but maybe the 608 might be a better option with regards to the extra immo functionality. As far as I can tell the 908 has ECU programming/updating whereas the 608 doesn't 🤷
Is there anything else?
Cheers 👍
Hi
No, have not yet had a chance to make a video for that...
I would say though, that when use the 608 for diagnostics, feels the same as the 908...
Obviously a proper comparison, would require check every menu, etc...
👍👍👍
@@LMAutoRepairs Thanks for that. Knowing my luck I'll get a 608 pro with the J2534, XP400, extra adapters, gbox 2 then Autel will bring an all singing all dancing model out 🥴 I see the updates seem to be less than £700 for the 608. I suppose that's one good thing. Here's hoping you get time to do a vid
Thanks Louis 👍👍👍
@@timmehlittleloud2251
Well... if you want to wait for the latest model, you will never buy anything...
😋
But I know what you mean...
They have the Ultra, but at that price tag, is definitely not for me...

My pump didnt have a Woodruff key just a pin hole onshaft ever come across that thanks
☺️
👍👍👍
good morning
👋
Can you give me a link for the blanking kit please. Thank you.
There is plenty on eBay... just search for z19dth swirl flap
👍👍👍
Hello mate, where are you based? Would you be able to help me code some bmw injectors? I’ve seen your video on it but don’t have access to the diagnostic tools?
Any decent garage should be able to do it for you...
👍👍👍
Can't the swirl flaps be removed without such complicated disassembly?
You can try...
☺️
👍👍👍
Will this mod have an impact on low engine speed behavior an emissions?
Not really...
👍👍👍
@@LMAutoRepairs Nice. Was there an option to disable the swirl system in the ECU? Like the "EGR off"?
Yes... through remapping...
But the way I left it, will work just fine...
The engine will loose torque in low revs. I don't know how much it will be. The reason for the swirl flaps is that in lower revs the lenght of intake manifold needs to be shorter than in higher revs. This is achieved with the flaps. Without the flaps it will be only longer manifold option available through the whole rev spectrum.
Not quite like that... but yes...
The difference in torque is negligible...
I can put two identical cars, one with these flaps, and another one without...
I can bet you can drive both, and you will not fell a difference...
👍👍👍
You skipped the montaje of the flaps, you didn't show us how you put them back together. Did you have to drill in the blankets ?
No I did not...
Watch again...
👍👍👍
Mmmm bar b Q smoke, then strawberries now we know what we've been missing. 😄👍
😅😅😅
👍👍👍
Where did all that carbon come from in the intake manifold?
EGR...
👍👍👍
Hi, I got my Vectra lost power. Error code shows intake air system leak. Gave to a local garrage and they changed new EGR valve. The problem came again while on road and broke down in middle of road as it cant climb steep roads. Can you advise me to fix it. Where can I take it to. Do you have mobile service repair.
Why was the EGR changed?
What tests have been done?
Whatch this, it might shed some light on your issue...
ua-cam.com/video/LteG70wGVqw/v-deo.html
👍👍👍
He just diagnosed with the OBD tool and asked me to buy new EGR. I have bought it and gave. Still not sorted.
Great repair video Luis, but come on, don't leave us hanging like that, where were the strawberries from?
Would have to ask the missus...😋
😅
The smoke test got me thinking. Does it test the whole system or just the manifold?
The whole intake... Well, depends where you inject the smoke...
👍👍👍👍
Do petrol cars have problems with them what year did they start using them on all cars because my 1.6 vvti Corolla has never had that problem so I guess they don't have it
Not all have them...
👍👍👍
@@LMAutoRepairs Is it all the cars with direct injection have it
How long did it take to get manifold off
🤔
I don't remember those details now...
Sorry...
These flaps are called swirl flaps ? What is their function ? Great video ! Well done !
Yes... that's what they are called...
The idea behind them is to force the air to swirl, which in turn improves the fuel/air mixture at low speeds...
Thank you for watching!
You will find this flaps in all 16v engines that are turbocharged. As you know 8v engines have better acceleration in lower revs. So with this flaps ecu is closing one port in inlet manifold to improve accel from lower revs. This is closed until 800- 1800-2000rpm range. With this blanked car will slower accelerate but will not be so noticable. Real fix will be to buy new manifold or flap rebuild kit.
@@mr.t2585 Thank you for your explanation. Sooner or later I am thinking to block them on my Audi Q7 3.0 ltr diesel. Inlet might as gunky as this Astra. What you think ?
👍👍👍
@@loubakker5000 This 1.9 engines have a tendency to eat this flaps. Flaps get loose and gets inside the cylnder and the rest.. you know. If manifold is bad yes get rid of them and remap.
How did you do that to the flaps motor? Programmed out?
No... just left it in place... as explained in the video...
@@LMAutoRepairs So the car thinks the flaps are still there?
Yes...
Is that the same PD engine that VW use
No... this is not a PD engine...
Is a CR (common rail)...
Bloody swirl flaps, more trouble than they're worth. I just had to remove my intake manifold on my astra 1.9 cdti sri to delete these and it was a pain the the ass.
😅
Yes, they are not easy to get to...
👍👍👍

A new OEM on eBay is 153 pounds which if it last another 5 years isn't too bad

hi lm auto how did u make ur leak tester
Read the video description...😉
👍👍👍
thankd didnt see this
👍
Engineers are designig diesel motors to make low emissions with egr,dpf,adblue etc after a hundred k miles all that systems occuring problems so car owners looking ways to disable them.they sold us that moore expensive diesel cars for fuel economy now diesel is 10 percent expensive then gasoline at pump where is that economy?also pay 2x for maintance,clean inlet manifold,repair diesel injectors and high preassure pump so i'm far avay from diesel cars,i sold my astra 1.6 cdti (2016) 15 days ago.driving a Renault megane 1 33 liter 140 hp turbo gasoline car & i'm happy with it.astra consumption was 7.2 liter diesel/km megane consumption is 6.8 liter gasoline/km no diesel motor sounds,no vibration no smoke.let diesel is for heavy trucks not for my car.
👍👍👍
and what about the washing machine? don't tell me you were not able o fix it
LoL
Fixed it once before... this time missus used it as an excuse to get a new one... lol
😅
intake thortles fours
😅
👍👍👍
Its not an engine light its for the exhaust
Not sure what you mean...
Thank you for watching!
@@LMAutoRepairs that light that everyone says is an engine light is actually to say theres a fault in the exhaust/emmisions side.
An engine light has a spanner or electrical spark symbol
In both of my Saab Tid, my Alfa Giulietta JTDM, my lads 206 and his 5 series, that's the Engine Management Light (EML). It is described in the manuals and owners handbooks in the manual. There is, on some vehicles, an exhaust warning for the DPF, but that is definitely the EML lit up in this video. @@ninetofivegirl5545
I've not watched the video yet. Let me guess? Swirl flaps leaking 🤦
🤷♂️
😊
If you not eliminate PCV to turbo and EGR, the result is the same, all dirty.
My god it's got petrol in it most of them are on zero
😅

Shw yo miss in your video
What?
You should not speak with mouth full ha ha
