Brilliant video. Cleaned throttle body. Done 180000 miles. Really dirty. Car drives alot better. Next will be egr in a month.
Thanks mate for doing the vid.
Happy to help!
Thanks for this very helpful video. Much appreciated.
Hello. Great video! I’m thinking about cleaning my throttle body. Can I use MAF cleaner to clean IAT sensor?
Great job on the video👍🏻
great video,,what size hose are the vacuum lines?mine all need replacing
Good guide. I did this the other day but I think my valve is sticking and have ordered a used throttle body that has been tested. Do you think it is ok to use throttle and intake cleaner spray? I'm just a bit unsure with the throttle body in these engines being plastic. Many thanks
Hello friend. Great job, very useful video !
With your help and videos I'm trying to eliminate the P2141 DTC code from a 2.0 TDCi Ford C-max 2007 car. Unfortunately this cleaning procedure haven't eliminated the DTC code. Do you have any ideas what to check, clean next ?
Thanks a lot in advance
Hi, just cleaned my complete air manifold. I took it of the engine because it smokes a lot and runs like a tractor in the morning for about 30 seconds to a minute. After that it's fine. Nevertheless I didn't clean the " throttle body" though and the problem is still there. Next I'm going to do is clean it like in your video. If it doesn't help it doesn't hurt anyway! Thanks for the video!
thank you for very good videos for my volvo S40
+Marian Ion Simonca check our other videos and subscribe for more Volvo tutorials!
hello, can i use that from a volvo V50 1,6 on a S40 2,0? or is it different
Hello, at 2:50 you disconnect a hose line, I have found out that it controls the butterfly flaps.
But when I bought my car it was unplugged completely(there is also a screw in the hose to block it off). Any reason why it was unplugged ?
Car seems to drive fine.
I have air bubbles in the exit pipe of the diesel filter.
I can't see if there are any bubbles in the inlet as it is a black pipe. Is there any way that I can detect if there are bubbles in the fuel before the diesel filter?
I saw your issue in comments below. It might be EGR. PUt an aluminum or metal blanking EGR and you will be fine. It will reduce oil steam emission in engine and throttle body will be more cleaner later. Also Sometimes theory le body can leaking because The air has oil steam . I personally put Silicon And plastic glue all around this piece And no more leak , better performance
Hello, was there a noticeable performance increase after cleaning?
Hi ! And thank you for the video ! Can i clean throttle body with CARBURETOR END CHOKE CLEANER SPRAY ? Thanks again !
does anybody know if this will help my not starting problem when hot
Thanks for helpful video.
By the way, is it possible to remove the Air Intake manifold body and clean it? I saw somebody was cleaning the inside of the Air Intake manifold of other car.
Sure, it's possible. But most likely you will need a set of new gaskets for the manifold.
Nice video. I had my Volvo not starting yesterday, today I just removed the hoses from the throttle body it started. I reconnected the hoses and it now starts with the second try. Is it a case it just needs cleaning?
Can I use carburetor cleaning spray?
Remove it and check if flaps are moving freely.
You can use carb. cleaner.
What are the symptoms that you need to clean this?
Hi, very good video! I have one question. Can you explain what
is the purpose of taht two object to which is connected to the vacuum lines?
If you are talking about the butterfly flaps, those are there to direct charged air through or bypass the intercooler.
Actually I wondering what that vacuum do there? Is it control throttle valve or what?
Those flaps are controlled with vacuum.
And since this is a diesel engine there is actually no throttle in the intake. Those flaps are just directing air one way or the other, or close the intake when you turn off the engine.
Now it's clear. Thanks ^_^
Thanks for taking the time making this video it's a real help. I have the 2 litre diesel 136 bhp in the cmax. On start up first thing in morning the throttle is really poor, but rest of time it's perfect. I've bought the carb cleaner and will do this tomorrow. Just one question, do you have to do a throttle body reset?
Hi! You can also check EGR.
mr-fix already replaced egr last year.
I didn't expect it to be caked so much in carbon. I used a flat head screwdriver to chip it away. To be honest I should remove manifold and do a thorough job.
you will be amazed if you take off inlet manifold and see all the gunk in it...clean inside off it with oven cleaner....while that's off clean egr Valve and egr pipe which it also full of crud...results are very positive and it let's your engine breathe better...improved power and mpg
+Gary shaw EGR, intake and VGT cleaning soon.
Just one question, how oil can access this hoses?
Same engine, 2009, on idle it's a little bit shaking and the central side of this body is a little bit oiled, not leaking, but where from this oil come and how it got outside.
crankshaft breather
Heloo my friend really thank you for your videos about tips peugeot cars...i have one question where i can get free repair manual on web site i really need that i have peugeot 407 sw 2.0 hdi 100 kw 136 ps 2006 year do you know maybe where i can get it..thank you...
I know I'm late to this video. I've come here for a guide as I've been told this needs to be cleaned on my car. I have the v50 2.0 D SE 2005. on cold starts it's absolutely fine but when the engine gets up to temperature and I stop the car it will give me hell to start up again. I got told that flap is jamming open when the pipes expand but destracts when engine is cool? also feel loss of performance when engine is hot
If I have to guess I would say that one of the flaps is stuck close or loose inside the body. Or the vacuum line that controls it is leaking. Or the vacuum valve. Or one of the temperature sensors...
Can you scan your car for trouble codes and check some of the engine parameters with a scanner?
Good video. Thx
:)
Hello Mr Fix, i have a 2014 Peugeot 508 2.0 Diesel Allure and want to disconnect the vacuum pipe on the throttle body. I can't get it off and don't want to pull too hard as might damage vacuum body. The rubber connection on the body is soft and not a hard pipe. Have you come across this before?
Try gentle warming with hair dryer, then try to pull it off.
I suspect my throttle body has some issues. My car sometimes lacks power under 2000rpm badly.. and it's smoky after 2000rpm on heavy accelerations. Yesterday i got off the car and i hurd some buzzing/humming sound from the engine area.After i stoped the car and ignition switched off. I pulled the vacum line from turbo vacum valve( brown one) and buzzing stoped. Started again and checked again , buzzing stoped when i pulled vacum line so i suspect a vacum leak somwhere. What's wierd for me is why is my intercooler COLD after a long drive? If i have a broken membrane in one of my vacum actuator valve witch controls the throttle body will it bypass the intercooler? Thx.
If your car is bypassing intercooler then it will be cold and performence will be lower. This can be caused by fault or because your DPF is regenerating.
Buzzing vacuum valve is not an indication of issues with vacuum - those valves are controlled with PWM signal and this is just how they work.
Your VGT might be stuck or not moving in the correct range which would also cause performance issues.
If you have a lot of smoke when accelerating, then you might have some boost leak.
Hello
Can you help me please ??
What is petroleum ether ?
Give me an example or a link to buy this. Thanks you very very much !!!
Thanks !!

Nice video, My fiesta 1.4 tdci keeps stuttering when cold. even changed injector no improvement :(
Please check coolant temperature sensor.
Thanks wil do that :)
Hi mr fix, love your videos.
I have a ford galaxy TDCi 2.0., I have a slight hesitation between 1500 and 2000 rpm, only when under very light throttle or when no throttle, have had a new fuel filter fitted and don’t have any DTCs,
I was searching and then came across a post about how cruise controls slow cars down in a diesel car, reward that it’s buy closing of the air in the egr throttle body.... that’s when I came back to your site and watched the video....... reason, when I have cruise control on it all works fine but recently if I go down hill it does not slow down, so my thinking was that it could be the throttle sticking as if air is still getting past the flap it would not slow the car leaving me to think it could be the same reason why it’s giving hesitation at low revs...
Sorry about the long post
Many thanks
Steve
What year is your car?
Can you show a video on inlet Manifold removal?
Unfortunatelly I sold the car before doing it.
SuperHammys i
Wyczyścilem przepustnice jak w filmie i teraz auto ciężko odpala, a jak już odpali to śmiga aż miło. Możesz coś podpowiedzieć.
Nie zostały pomylone przewody podciśnienia?
thanks for the video! I removed cleaned and then refitted my throttle body thanks to this video!
Just a quick question: in my throttle body, one side was constantly springing back into open position (as you showed), but the other side would just open and close with no spring action - this is also the side that leaks a bit of oil - what could be the problem here?
Both sides should spring back. One to open position, one to closed position.
If there's free movement, then most likely plastic gears are damaged. You'll need to replace the throttle body, or just the faulty plastic mechanism.
mr-fix that's a bother :/ it does make sense now that you mention it... so one side is for normal intake and the other side for turbo, correct?
Both are connecting turbo to the engine. They just direct the air through or bypass the intercooler.
And when you turn the engine off, both are closed to help smooth things out.
mr-fix that explains the weird way it switches off :) I'll try to order a new one, thanks!
@@CloakedPerv Did you get any fault codes?
Forgive me if this is a dumb question but why would a diesel need a throttle body? They draw a fixed volume of air don't they? The lack of a throttle body and butterfly valve prevents pumping losses. Why does this diesel have one?
Having gone to all this trouble, why not remove and clean the manifold as well; it appears a straight forward job. Or is there something I haven't spotted that is likelt to cause major headaches?
Taking the manifold out would most likely require a set of new seals to put it back together and not cause air leaks.
Thanks, I was thinking that would not be a problem and was surprised by your answer.
That is until I noticed that the inlet manifold and cylinder head cover are one assembly; consequently much more expensive than just the four seals of old!
On these you have to remove injectors and the inlet is part of the rocker cover
Can you publish manifold guide ? I cleaned my throttle body and egr pipe which was clogged 30% at exit to body. my 407 body looks a bit different but it's almost same procedure. Manifold looks terrible so I need to get back there.
PS. does oil like your video in body tell anything about turbo condition ?
Didn't clean the manifold yet.You can't diagnose turbo without actually looking inside the turbo. Oil inside manifold is most likely coming from the crankshaft breather and it's common in turbo diesel engines.
Thanks you planning to do it somehow before autumn or ..?
If I had time I would do it even today :)
Hope to do it this year.
Sadly my 1598 error is still up. It does not light up MIL. Any clue ?
J'ai eu le même problème sur ma voiture mais je sais plus les durites ils vont ou ?
Witaj. Właśnie wymieniam wysprzeglik w Volvo V50. Wiesz może czy trzeba opuszczać sanki do wyjecia lub odsunięcia skrzyni? Nie mogę znaleźć żadnych informacji w internecie. Pozdrawiam.
W 2.0D nie trzeba.
mr-fix Bardzo dziękuję. Biorę sie dalej za robotę. Pozdrawiam.
Thanks for the video. I am trying to get rid of sporadic engine power hick ups, momentary loss of power and sometimes a just bit jerky idling (no biggy but I can feel it does not run smooth) on a 2008 Citroen C5 2.0 Hdi and was wondering if the throttle body could be the culprit. How do you know when to clean and when to replace the throttle body?
It’s pretty easy to disconnect the part and take a look inside.
@@mrfixpl what exactly should I be looking for?
is this similiar to peugeot 407 2.0 hdi ?? and can this cleaning damage my electronic throttle body ?some help here please my engine turns off at idling when im cruising with ac on ?
there's a lot of 2.0HDI engines. This one is 136PS/140PS.
Check if your timing belt is not loose, and if the belt tensioner is OK. If not your upper and lower sensors can go out of sync and ECU will turn off your engine to prevent damaging valves and pistons.
this happens to me only when im with AC on ?
Can i clean my throttle body like in the video ?
should i replace my tensioner belt ?
Help please ???
Very good Job
😀
Great tutorial! My 407 2.0 HDI has recently lost power, I have been trying to find faults and have found that one of the flaps on mine has no return action and just flaps around without any resistance, could this be the cause? Thanks.
This can restrict air flow so it can be responsible for power loss.
mr-fix Thanks for the reply. I changed it today, unfortunately I still have very little boost, running out of ideas now. Thanks again.
Unfortunately there's a whole list of little things that might be wrong and will cause low boost. Some are directly related to the turbo (like the vacuum valve controlling VNT, sensor on the turbo, IAP sensor on the intake, boost leak) and some can cause the engine control unit to go to low-boost mode to prevent further damage (fuel rail pressure out of range, accelerator pedal potentiometer fault, timing belt out of sync).
Would be helpful if you could run a quick scan of the car to see if there's some error code pointing to a fault.
mr-fix thanks, I’ve got someone to scan it arranged for end of next week, hopefully they’ll find something although I have no warning lights of any sort displayed on the dash.
I have exactly the same as you describe. Did you manage to get to the bottom of the problem?
Hello. Nice work!!! Did you need to recalibrate it afterwards? I want to change mine even though is not broken but still leaks a little oil. Do i need recalibration for it? If yes can I do it manually and how or it needs to be done with Computer. I would greatly appriciate your help.
Thank you!
No calibration needed.
@@mrfixpl thank you so much. Finally I can change it. My car is a Peugeot 406 coupe with a 2.2 hdi motor.
Keep up the good work and thnx again!!
@@zamirkabo9705 did u changed it ? Can u give me some updates
@@adisl6659 yeah! what was the result of new? mine is leaking oil from the throttle body and didn't know where from on the throttle body. It has to be from one of the gear caps or something around there.
Still leaks from the valves, I think it’s supposed to…😢
Awesome video thank you very much
Help full video thanks
Happy to help!
What is the engine code in this motor?.
i checked out my trnsioner belt to a mechanic and its ok . my car has a rough idling and turns of when im stoping only when im with AC ON what could be ? help pleasee
Maybe your AC compressor is soon to be broken and it resists so much on the accessory belt that it can stop the engine?
My car is doing the same, cutting out when I take it out of gear when slowing down. Sometimes it won't start again for days.. :-( Hadn't considered that something might be resisting the belt. Thanks for the idea!
The right part of the throttle housing there is a circle part which a vacuum line goes into , mine was disconnected from previous owner any idea why ? Should I plug it back in?
Those two butterfly valves have different normal states (one is normally open, one is normally closed) and work opposite of each other. If one of the valves is faulty (for example stuck closed), you don't wont the other one to also close, so you disconnect the vacuum control line.
@@mrfixpl Thanks alot for the very fast reply ! Ive have been trying to research this for a while now and I finally have an answer ?
What do you suggest i do now ? Leave it like this untill the butterfly valve is fixed ?
Should I attempt to fix it ?
Thanks alot again
Take it out and check if both butterfly valves are moving correctly. You can apply vacuum with a syringe to check if it moves correctly.
Is it the same in 1.6D c30?
HuntingWales sorry, no. 1.6D is a completely different construction.
If we'll make similar video about 1.6D it's best if you subscribe to this channel :)
Great video but i am curious, why does this throttle body have two air intakes? Is this version a twin turbo?
The version in the Mk4 Mondeo only has one air intake..
Some engines have intercooler bypass. Flap regulates if the intake air should go though intercooler or bypass it.
@@mrfixpl interesting. I did not know this. Once again, great video and thanks for sharing. 👍
I have some rubber pipe conencted to mine. How do i remove it on a volvo c30?
+Domo Mandingo this video is from C30. Where do you have an additional pipe connected?
One flap is broken and the other doesn’t have a vacuum pipe doing to it. What would this cause? Vehicle is currently lacking power
It could cause both flaps to stay closed or air being improperly guided though the system.
mr-fix ok thank you. If I’m able to remove the flaps what would that do?
Hello guys,i have a problem with my Peugeot 307 2.0 100kw HDI.I cleaned throttle body and at 2100rpm my turbine dont start...what could be a problem?My turbine doesnt work at any rpm after cleaning...HELP!!!
Damaged/disconnected inlet manifold pressure sensor.
It shows me on my bord Exhaust system faulty... and my engine make some weird noise... never heard him that loud... i only cleaned that throttle body and yes... i broke my car.what to do?
Boas é normal sair um bocadinho óleo daí
Hi
I have focus 1.6 tdci 66kw. When l switch off the engine and the entire car start to shake. If anyone knows what is the problem. Tnx
maybe the fuel doesnt shut off properly -> engine keeps running on its own ..? as far as I know, Diesel Engines can only be stopped by cutting the fuel.
My scanning showed following faults:
P002 Powertrain
P242F Powertrain
U1900 Network
U2023 Network
Do you think this have anything to do with the sensor or the Throttle?
P0002 - Fuel Volume Regulator Control Circuit Range/Performance
P242F - Diesel Particulate Filter Restriction - Ash Accumulation
U1900 - CAN Communication Bus Fault
U2023 - vehicle connection network fault
So i should sell the car? 😁
1. Clear all codes
2. Take the car for a ride.
3. Scan again for codes and check which are back.
So i cleared the faults and took about 30-40 min ride on the highway. (Average speed 120-130) when i arrived i got only P242F as fault.
can anyone explaine me, why is there two air valves ?, because i know anywhere is one air valve not two
intercooler bypass
will this cause dpf soot messages
Unlikely. This message shows when ECU estimates that the filter is full. That estimation is based on the readout from the differential pressure sensor (installed next to the battery, with two line going form it down to the filter). It reads pressure before and after the filter and if there's pressure build-up before the filter, it calculates how clogged it is.
This has nothing to do with the intake manifold.
Do you know why there could be oil there?
la recirculacion de gases del carter, se condensa aceite en todo el circuito de admision
Why was one of the flaps open . On mine both are closed
One is open by default, other on is closed by default.
Hi!, i must have diagnostics tool ? .
No.
mr-fix Thanks 😁
Is it normal to have Oil in the intakte on this engine?
Depends on how much oil is there. But yes, oil gets there from the engine breather.
@@mrfixpl Okei. Thanks for the quick reply!
how can i relearn?by disconnecting the minus on the battery?
No need to relearn. The valves are connected with vacuum lines, and both MAP and IAT sensors does not required any kind of calibration.
@@mrfixpl thank you so much
1) Why would I need to clean the throttle body? 2) Why are there 2 air intake pipes?
2) it’s an intercooler bypass. ECU decides if charged air should go though the cooler.
1) if the flaps inside are sticky it will not work correctly.
@@mrfixpl Just out of interest, how many miles would you expect to get from a 50 litre tank of diesel attached to this 2.0 diesel engine? I currently get about 400 miles when doing motorway miles. Is this low? I took the car to a Volvo main dealer who could not find any fault codes on the car. Thanks in advance.
@@mrfixpl Hello where are you based if I would like you to look at my car?
In my C30 I manage to get 450/500 max.
I’m in Poland but I’m not running a garage. Just this YT channel for now.
My car is a Volvo 2.0d 2008 but it only has 1 intake pipe
Some Volvos with 2.0d will have just 1 valve. Mine had intercooler bypass, so that why there are two.
What was the problem? Bad first start?
Shaking when turning off and smoking on heavy acceleration.
Filip Horvatic It seems that almost every 2.0D engine has that problem, but no one knows how to fix it ;__;
+John Szczepanski Next I'm cleaning the EGR valve to see if that helps.
+mr-fix Did this helped on smoking?
mr-fix did this fix the shaking and smoking issue?
I did the same, but the turbo is not working now🤔
Check vacuum lines if there's no rupture. VNT turbo is controlled by vacuum line.
@@mrfixpl i think that i have damaged the sensor by cleaning with unproper spray?
@@mrfixpl Thank you man!!! It's was the vacum line, please in email sent me your address, i want to send you some swiss chocolate 🍫 😉
@@ecosafe6233 Happy to help! Catch me in private message on facebook or instagram 😀
My one is. Not a twin porn what’s the difference it’s the same engine
There were versions with and without intercooler bypass.
mr-fix am sure It has an intercooler but only one port strange great video though t
mr-fix is The engine you’re working on have an intercooler
Both engines have intercoolers.
But in mine there's an additional bypass so the controller can choose if the turbocharger air should go through the intercooler or should it go directly to the engine.
In your engine there's no bypass and turbocharger air is always going through the intercooler.
mr-fix Okay thanks for that in your opinion what is the better set up
I think it's not enough.. you must clean all the thruthl
Remove throttle body, and use brake cleaner spray inside don't need to use circuit cleaner or stuff :)
Oh my god .. Why remove all of parts ? Just use Brake cleaner .... It's just perfect , for MAF and this throttle body.
+Cerisette Kotomi because gears that drive those flaps often get broken. I always try to make my tutorials with as much disassemble as it can be necessary when fixing certain issues. It this case someone might need to remove it to inspect those flaps or even replace whole element.
+mr-fix Thanks :) !
you have to be wery dumb to use brake cleaner on maf
Very* Yes i support your statement;
It is not wise using an aggressive "cleaner" on sensitive electronics.
It really irritates me when he keeps putting the bolt in and out. Just leave the damn thing out and get on with it ffs.
waste of time
tanto como leer tu comentario, en cambio, haber dicho que junto con el cuerpo del acelerador hay que limpiar tambien el colector de admision, los conductos y las valvulas, habria servido de algo.
