Man, you are a legend! You saved me a lot of headache, this thing worked like a charm. My car had lost power and on acceleration drop in limp mode, this helped it all
Massive thanks to you. I was about to go and a buy a replacement and thought may as well give it a clean up. 2,000 miles later and all is still fine. Before it went into limp mode within the first couple of miles on every journey.
Thanks for this video. My xc90 was going into limp mode daily on acceleration, mainly off cold. Cleaned the mesh. Thought it would make no difference. That was 3 weeks ago. Sorted. Not gone into limp mode. Brilliant..Thanks..👍👍
Amazing sir!!! My Volvo Xc90 hadn't been able to drive for a week now. Maf sensor and air temperature sensor as well this one u cleaned now, i did exactly as u did and amazingly it worked. Thabk you a lot! And i cleaned my AGR and all the pipes that been colecting Carbon inside. I've got some work to do more as well but i ll clean my whole engine yhis way. Thank ypu a lot ypu saved me some money for sure!
Used this video to trace a fault on a 2014 2.0ltr XC 60. Valve was mounted in a different position but recognised it straight away, quick blast with some solvent cleaner and problem solved, excellent information.
check for overboost fault within diagnostic ecu scan. thats 1st sign your loss of power is related to dirty tcv. happend to mine on full throttle on higher gears (mainly 4th, sometimes 5th, never 6th) and ocassionaly on 2nd, pushing from bottom revs.
Hi I have overboost issue and when I step on Gas and let it go it makes huge hissle sound and air coming out off the air intake.. ao you think its this issua so maybe this Valve also? Mechanics at volvo just guessing but not having a clue IMO 🤦♂️ I spen 1,500 on flirl flops replacemen - still makes annoying noise.. thx
..Update.. I've just completed this and the car runs like new. All the power is back. Mine was covered in a thin layer of mud. I didn't manage to get the bottom bolt back on but I'm probably going to replace this valve in the future. Thanks for the great video!
Hello mate, thanks for sharing all your findings. Many garages need too watch your vidsos, alot of faults boil down to old school trouble shooting and research to find the 20pence item that has failed, rather than replaceing entire units worth many hundreds of pounds, with the problem still not being cured. Your a saint to old cars like mine👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
Hi SiRobb. I did everything like You in this video. I also clean contacts with contact cleaner, put everything back together after about half an hour when contact cleaner evaporate and went for a test drive. But it is wors than it was. The car has no power when press pedal harder, the revs rise but nothing else. And I got message engine service required. Where I was wrong?? I also have noise when remove oil filler cap and my vakuums are OK. I tested everything from Your videos, I change all engine mounts, the hoses are OK, vakum pump is OK. I did not test only turbo actuator cause it is too hard too reach.
Unfortunately, you can't avoid testing something because it's difficult to reach so you may have to take it to a garage with a lift. If there's a loud popping noise, you need to check the vacuum system again. Live data showing MAF and MAP readings will also help a lot.
@@sirobb I agree. I did not test it cause I didn't get to it yet. But my car drove pritty well before cleaning. I expected more power or just the same. Not worse. I will clean it one more time tomorrow.

hello how are you, i have a problem and i hope you can help me, I am not a mechanic but my dad is a mechanic. Two days ago my dad bought a 2004 xc90 D5 But he bought it on the grounds that it does not work and he wants to fix it. The annoying thing is that in Syria we do not have spare parts for cars or professional technicians. Even my father deals with old cars that do not have a computer. Regarding this car, its previous owner said that he replaced the turbo, but The engine torque is still weak, today my father checked the large pipes connected to the turbo and found that they were not installed in the first place!! The strange thing is that this sensor that you showed in the video was connected to a tube only from the back of the turbo, but the other tube was not there at all, and we do not know where it goes, and my mother tongue is Arabic, so I find it difficult to search, can such a piece cause With the loss of engine torque, can it be dispensed with and just repair the big turbo pipe seals? Please, I am waiting for your answer, I am sad about disabling it and desensitizing it by the previous reformers
@@sirobb I think this is the fifth time that I write an email and it is automatically deleted from the comment checker for UA-cam... I put the email in my channel below the channel name.. Please can you have a look at it.. Thank you
Really? That's very interesting to know! How does the clip remove? Do you unscrew it or do you have to bend the metal collar? It seems like it would break easily.
Hello and thank you for your videos. My v60 d6 (d5 215hp + plugin electrical engine) won't go over 200km/h , although it seems normal on the rest. Could this be the problem for not doing the regular top speed (243kmh)? Thank you
@@RollingwithTheRobsons I'm pretty sure boost is controlled by an electric servo which moves the VNT. Getting a code read done using a Volvo Dice and Vida software will make troubleshooting a lot easier and avoid expensive and incorrect guesses. If the garage doesn't have it, find a specialist that does or you can obviously buy your own Dice. I sell them too.
I have two errors on my D5244T5 (2009 Volvo XC60) motor... P0234 and P0238. May they be created by the solenoid failing? Why are these errors connected?
@@sirobb you are right, I will have to continue guessing... I have those errors with lack of power beyond 3.000 rpm. I know that my throttle housing module is failing but I don't know if it may cause these errors and the lack of power at high speeds.
hey siRobb - i have a 2006 v70 with the D5 engine (D5244T4) my turbo makes a whisteling noise when i accelerate from 1 to second gear, and some oil leak at the bottom front of my engine, any idea what that could be?:O
@@sirobb what OBD scanner are you using? I bought cheatp elm327 bluetooth scanner, but I can't connect it with car, any suggestions witch would work. Volvo D5 2002
Can anyone help, i have a S60 D5 120kw Every time i hit the throttle i hear a whiste of air under the hood that last about a second every time the turbo spools up, i feel a bit of power loss and some black smoke behind me, all the air hoses are checked under pressure and it’s all fine, any ideas? Thanks
Great video :p Out of interest, if the BCV is stuck open would you expect an over boost condition conversely, if it is stuck closed a underboost condition? The TCV solenoid just before this system could also get stuck open and closed, what would be the symptoms of each solenoid being stuck open and closed is what i guess im asking :p Would be really helpful for diagnosis in the future.
Your turbo VNT is controlled by an electrically powered servo motor so you need to view the full movement of the actuator rod whilst revving the engine. Also check for air leaks in the intercooler and intake pipework.
Hello SiRobb I am hoping that you may be able to help me with an ongoing limp mode problem with my xc70 d5 2004 . I took the car to my independent garage to have it checked , they found the following codes codes . 4405 E C M E G R = Valve flow too low . 6805 Boost pressure control has faulty flow . 2503 Fuel pressure is too low . they also mentioned that could possibly be faulty fuel injectors ,or fuel rail . I CHANGED THE BOOST CONTROL VALVE, the one next to the air filter box , no change ., no change I they removed and cleaned the E G R valve ., no change , they checked the vaccum hoses as well I then took it to Volvo hoping they might have some previous knowledge of this issue , they wanted to replace the turbo but would not guarantee it would solve it , the service chap suggested that it could be worth checking and cleaning the interior of the turbo as the vanes do stick sometimes . the same codes were reported by them also . Took it to my independent who did this , said it was not very dirty and was sticking a little , no change . I then took it to another independent for a third opinion , they did not find anything either , but the car ran fine for about six weeks after they [ fiddled with it ] then it started again . I went back and while checking again the guy noticed anther valve behind the e g r pipe . I looked at your videos , which are very helpful, i spotted the cleaning of the other valve and thought maybe that is the problem . Took it there this morning , valve removed nothing obvious , cleaned replaced and still not running . I am about 600 pounds out of pocket so far and cant see an end to this , a new valve from volvo is £ 150 , as you can imagine i do not want to buy it if it is not the problem . When the turbo is working, sometimes the engine feels like the power is rising and falling , sort of a surging feeling ?and not a smooth increase in speed Any thoughts will be much appreciated . Regards Alex
My friend, please help me, I'm from Brazil and I have a mini cooper and use the same system as the video. My acarro has the following symptom: when stepping on the accelerator it makes a sound in the turbine as if filling and refilling the turbo. I installed a manometer and realized that when filling the turbo the pressure oscillates and when it is in charge maximum at 1 bar of pressure it stabilizes. Will the replacement of this solenoid solve my problem? thank you
Hi SiRobb - I have a 2007 V50 2.0 D. Recently it has had the starter replaced and since that, the turbo doesn't work, leaving the car working, but tardy. The garage won't look at it again. Looking at your video, it seems possible that he simply hasn't reconnected the rubber hose you first disconnected (or possibly he has damaged it). Is there any comment that you could offer that would help me try to rectify this ? Many thanks if you can. Regards, Jol
+Jolyon Yates Your engine is different to the one in this video and not every turbo is controlled with vacuum and a valve like this so begin by finding out how your boost is controlled, then work back from there.
Just taken this to pieces and cleaned (as per your other detailed video) and it's still running 22psi max and throwing fault code P0244 Turbo charger wastegate solenoid "A" range performance. Any suggestions I'd be grateful :)
@@sirobb not yet, the vacuum tester should arrive tomorrow so will test them both then. Can a faulty VNT trigger the wastegate fault code (P0244)? Thank you
Yes if the VNT remains in the high boost position when it should be returning to low boost there will be a mismatch in the expected data which could trigger a code and limp mode. Same with a boost leak in the pipework or a split in the intercooler or the EGR not functioning as designed. All of the expected air flow and boost levels needs to match the ECM calculations.
@@wigglysmigfoddleNo problem. The vacuum VNT testing video is here ua-cam.com/video/NxmjRaiqeAk/v-deo.html The actuator must hold vacuum and move the VNT lever through its full travel and return. Sometimes, doing this test alone can be enough to free up a sticking VNT. Euro 4 VNT is moved by a motor but the same full travel and return needs to be possible for correct boost as expected by the ECM.
I see no benefit to blanking an EGR because it's easy to make your car run well and leave everything standard. Have a look at my starter motor removal video and you'll see my EGR is very clean.
Hey SiRobb, could you please help me. I have 2003 Volvo s60 D5 96kW. Engine runs excelent, and power and delivery of it is normal. The vacuum system is not leaking, because I have sealed the hose going to the engine mounts, like you shoved in your video, so I do not have any poping noise from the engine. The only things that bothers me is that car tripped a message : Engine Service Required. And I have seen on my little scan tool (ELM 327, and inCar Doc app on the phone) that I have a code P0244- which is related to turbo solenoid (bad connections, vacuum leaks etc.). I have cleaned the little mesh on the turbo solenoid on the top of the solenoid. I also cleaned the oil separator and just donbe the regular service and changed the fuel filter. I have done this yesterday and the message appeared 3 months ago after I pluged the hose going to the engine mounts, which were leaking. I have aslo seen this three codes on my scan tool along with the P0244 I was talking about. And the last time I was checking the codes I did not have P0244, just thesee that I still have now. P0267- cylinder 3 injector circuit low P0087- Fuel pressure low P0094- Fuel leak small
You said that you currently don't have a P0244 but you do have fuel codes so you deal with the active codes first. Also, get the MAP and Intake Air Temperature readings on a cold engine with engine off and ignition on then get the MAF, MAP, Intake Air Temperature and fuel rail pressure readings at idle then see what maximum figures you can get for the MAF, MAP, Intake Air Temperature and fuel rail pressure reading during a drive. If you use Torque Pro, you can use the high/low gauges to record these figures.
@@sirobb Ok I will do as you said, thanks again for advice. But there was a misunderstanding, at the moment I have all 4 codes including P0244. I meant to say that on the last service I did not had it, but now I have it.
@@sirobb And just one thing, is that ELM 327 adapter, that I have, fine. Have you heard of any issues of it destroying the engine computer anything like that.

Bonjour je suis vraiment embêté je ne trouve pas d’où vient mon problème de décharge .je n’ai pas voyant moteur
Hey. Can you explain the problems when this goes bad? :)
Great, what are symptoms apart from dash lights
My V70n 2007 2.4D made a flapping noise at idle when the EGR was clogged. It also had a slow throttle reponse
Hi there,
got a "boost pressure control faulty flow" message.
Dying to know,cleaning ,did it have any effect ,whatsoever?
Yes it did.
Please read video description.
Thanks for watching.
sirobb hah...silly me..cheers!
Meu amigo, por favor me ajude, eu sou do Brasil e tenho um mini cooper e usar o mesmo sistema como o vídeo. Meu Transportando materiais tem o seguinte sintoma: quando pisar no acelerador faz um som na turbina, como se encher e reencher o turbo. I instalado um manómetro e percebeu que, quando o enchimento do turbo a pressão oscila e quando está em carga máxima a 1 bar de pressão estabiliza-se. Será que a substituição deste solenóide resolver o meu problema? obrigado
Write in english if you want something sorted out.
hello how are you, i have a problem and i hope you can help me,
I am not a mechanic but my dad is a mechanic. Two days ago my dad bought a 2004 xc90 D5
But he bought it on the grounds that it does not work and he wants to fix it. The annoying thing is that in Syria we do not have spare parts for cars or professional technicians. Even my father deals with old cars that do not have a computer. Regarding this car, its previous owner said that he replaced the turbo, but The engine torque is still weak, today my father checked the large pipes connected to the turbo and found that they were not installed in the first place!! The strange thing is that this sensor that you showed in the video was connected to a tube only from the back of the turbo, but the other tube was not there at all, and we do not know where it goes, and my mother tongue is Arabic, so I find it difficult to search, can such a piece cause With the loss of engine torque, can it be dispensed with and just repair the big turbo pipe seals?
Please, I am waiting for your answer, I am sad about disabling it and desensitizing it by the previous reformers
Hello. Give me an email address and I will find the parts diagram so you can see what is missing and where it should go.

Still waiting you 🌹
hey siroob - you can open that valve and clean it inside . You just must remove that metal clip/brace.
Really? That's very interesting to know!
How does the clip remove? Do you unscrew it or do you have to bend the metal collar?
It seems like it would break easily.
boskigrzegorz Thanks for the video , could you please explain how to clean inside it.Thank you. I am going to do this soon,
sreviz I dont think you can open it.
Instead you just spray brake cleaner in both tubes until it comes out clean.
I did it just now. Just to clean as you said.
And also a big Thank your for your time to post the video.

Hello and thank you for your videos. My v60 d6 (d5 215hp + plugin electrical engine) won't go over 200km/h , although it seems normal on the rest. Could this be the problem for not doing the regular top speed (243kmh)? Thank you
Newer D5s can have electric motors instead of this valve so it depends on how your boost is controlled.
@@sirobb Thank you for your help!
I am having power loss issues. The garage I used claims DPF sensor but it seems as if Turbo turns off during longer drives. Could it be this?
Not every car has boost controlled by this so it depends.
It’s an xc90 d5 2010z
@@RollingwithTheRobsons I'm pretty sure boost is controlled by an electric servo which moves the VNT.
Getting a code read done using a Volvo Dice and Vida software will make troubleshooting a lot easier and avoid expensive and incorrect guesses.
If the garage doesn't have it, find a specialist that does or you can obviously buy your own Dice.
I sell them too.
I have two errors on my D5244T5 (2009 Volvo XC60) motor... P0234 and P0238.
May they be created by the solenoid failing? Why are these errors connected?
I'm pretty sure your D5 has an electric motor to adjust boost not a vacuum solenoid like in this video so you need to test that.
@@sirobb you are right, I will have to continue guessing... I have those errors with lack of power beyond 3.000 rpm.
I know that my throttle housing module is failing but I don't know if it may cause these errors and the lack of power at high speeds.
hey siRobb - i have a 2006 v70 with the D5 engine (D5244T4) my turbo makes a whisteling noise when i accelerate from 1 to second gear, and some oil leak at the bottom front of my engine, any idea what that could be?:O
Lars-Sigurd Johnsen It sounds like you have a leaking intercooler which will need replacing.
what is that valve for
sirobb how did you measure boost ? Do you have any external gauge?
I use Torque Pro
@@sirobb what OBD scanner are you using? I bought cheatp elm327 bluetooth scanner, but I can't connect it with car, any suggestions witch would work. Volvo D5 2002
Can anyone help, i have a S60 D5 120kw
Every time i hit the throttle i hear a whiste of air under the hood that last about a second every time the turbo spools up, i feel a bit of power loss and some black smoke behind me, all the air hoses are checked under pressure and it’s all fine, any ideas?
Thanks
Did you solve the problem and how?
Great video :p Out of interest, if the BCV is stuck open would you expect an over boost condition conversely, if it is stuck closed a underboost condition?
The TCV solenoid just before this system could also get stuck open and closed, what would be the symptoms of each solenoid being stuck open and closed is what i guess im asking :p Would be really helpful for diagnosis in the future.
Hey bro ... is the same procedure in a d5 2009 v50 ?
No, Euro 4 D5 onwards doesn't have this valve.
SiRobb thanks for the help mate ... I have a problem with overboost and dont know what to do
Your turbo VNT is controlled by an electrically powered servo motor so you need to view the full movement of the actuator rod whilst revving the engine.
Also check for air leaks in the intercooler and intake pipework.
SiRobb thanks mate again ... gonna look at it
Can a turbo make a crank won’t start situation?
Cpb Win I doubt it. I have a video for solving starting problems in my list.
Hello SiRobb
I am hoping that you may be able to help me with an ongoing limp mode problem with my xc70 d5 2004 .
I took the car to my independent garage to have it checked , they found the following codes codes .
4405 E C M E G R = Valve flow too low .
6805 Boost pressure control has faulty flow .
2503 Fuel pressure is too low .
they also mentioned that could possibly be faulty fuel injectors ,or fuel rail . I CHANGED THE BOOST CONTROL VALVE, the one next to the air filter box , no change ., no change
I they removed and cleaned the E G R valve ., no change , they checked the vaccum hoses as well
I then took it to Volvo hoping they might have some previous knowledge of this issue , they wanted to replace the turbo but would not guarantee it would solve it , the service chap suggested that it could be worth checking and cleaning the interior of the turbo as the vanes do stick sometimes . the same codes were reported by them also .
Took it to my independent who did this , said it was not very dirty and was sticking a little , no change .
I then took it to another independent for a third opinion , they did not find anything either , but the car ran fine for about six weeks after they [ fiddled with it ] then it started again .
I went back and while checking again the guy noticed anther valve behind the e g r pipe .
I looked at your videos , which are very helpful, i spotted the cleaning of the other valve and thought maybe that is the problem .
Took it there this morning , valve removed nothing obvious , cleaned replaced and still not running .
I am about 600 pounds out of pocket so far and cant see an end to this , a new valve from volvo is £ 150 , as you can imagine i do not want to buy it if it is not the problem .
When the turbo is working, sometimes the engine feels like the power is rising and falling , sort of a surging feeling ?and not a smooth increase in speed
Any thoughts will be much appreciated .
Regards Alex
Where are you based Alex?
Hi Jersey ci
+Alexander Low When was the fuel filter last replaced?
hi dont know ,i have had the car about two and a half years and have not seen that on my service bills .
what is your name if you dont mind
+Alexander Low Before doing anything else, change the fuel filter. Only use genuine Volvo, Mann, Bosch or Hengst.

My friend, please help me, I'm from Brazil and I have a mini cooper and use the same system as the video.
My acarro has the following symptom: when stepping on the accelerator it makes a sound in the turbine as if filling and refilling the turbo.
I installed a manometer and realized that when filling the turbo the pressure oscillates and when it is in charge maximum at 1 bar of pressure it stabilizes. Will the replacement of this solenoid solve my problem? thank you
Hi SiRobb - I have a 2007 V50 2.0 D. Recently it has had the starter replaced and since that, the turbo doesn't work, leaving the car working, but tardy. The garage won't look at it again. Looking at your video, it seems possible that he simply hasn't reconnected the rubber hose you first disconnected (or possibly he has damaged it). Is there any comment that you could offer that would help me try to rectify this ? Many thanks if you can. Regards, Jol
+Jolyon Yates Your engine is different to the one in this video and not every turbo is controlled with vacuum and a valve like this so begin by finding out how your boost is controlled, then work back from there.
Just taken this to pieces and cleaned (as per your other detailed video) and it's still running 22psi max and throwing fault code P0244 Turbo charger wastegate solenoid "A" range performance. Any suggestions I'd be grateful :)
Have you tested the VNT actuator for holding vacuum and the VNT mechanism for full travel and return as per my other video?
@@sirobb not yet, the vacuum tester should arrive tomorrow so will test them both then. Can a faulty VNT trigger the wastegate fault code (P0244)? Thank you
Yes if the VNT remains in the high boost position when it should be returning to low boost there will be a mismatch in the expected data which could trigger a code and limp mode.
Same with a boost leak in the pipework or a split in the intercooler or the EGR not functioning as designed.
All of the expected air flow and boost levels needs to match the ECM calculations.
@@sirobb thank you Rob. You are a star! I'll update this when I get to the bottom of it :)
@@wigglysmigfoddleNo problem. The vacuum VNT testing video is here ua-cam.com/video/NxmjRaiqeAk/v-deo.html
The actuator must hold vacuum and move the VNT lever through its full travel and return.
Sometimes, doing this test alone can be enough to free up a sticking VNT.
Euro 4 VNT is moved by a motor but the same full travel and return needs to be possible for correct boost as expected by the ECM.
hy.an opinion about blanking my egr ?or benefits. d5 2002.thanks
I see no benefit to blanking an EGR because it's easy to make your car run well and leave everything standard.
Have a look at my starter motor removal video and you'll see my EGR is very clean.
+SiRobb and the oil in the big house is a normal think?
+andreiman2008 Yes a small amount of oil is ok.
It comes from the turbo seals and is normal.
The D5 shouldn't use any oil between changes.
+SiRobb can give a watch to my chanel at the video:turbo sound and give an opinion?thanks a lot.
+andreiman2008 I've watched your video.
Mine used to make the same noise before cleaning my boost solenoid.
Have you opened yours and cleaned it?
ok.my english is bad :)). how do i test this valve with a manual vac.pump ?
Have you tested the VNT actuator?

@@chammysammy2513 sounds normal. What is your question?
Hey SiRobb, could you please help me. I have 2003 Volvo s60 D5 96kW. Engine runs excelent, and power and delivery of it is normal. The vacuum system is not leaking, because I have sealed the hose going to the engine mounts, like you shoved in your video, so I do not have any poping noise from the engine. The only things that bothers me is that car tripped a message : Engine Service Required. And I have seen on my little scan tool (ELM 327, and inCar Doc app on the phone) that I have a code P0244- which is related to turbo solenoid (bad connections, vacuum leaks etc.). I have cleaned the little mesh on the turbo solenoid on the top of the solenoid. I also cleaned the oil separator and just donbe the regular service and changed the fuel filter. I have done this yesterday and the message appeared 3 months ago after I pluged the hose going to the engine mounts, which were leaking.
I have aslo seen this three codes on my scan tool along with the P0244 I was talking about. And the last time I was checking the codes I did not have P0244, just thesee that I still have now.
P0267- cylinder 3 injector circuit low
P0087- Fuel pressure low
P0094- Fuel leak small
Have you done a leak back test on all 5 injectors?
@@sirobb No I have not. But how could this be related to Engine Service Required message, or P0244 code I am getting.
You said that you currently don't have a P0244 but you do have fuel codes so you deal with the active codes first.
Also, get the MAP and Intake Air Temperature readings on a cold engine with engine off and ignition on then get the MAF, MAP, Intake Air Temperature and fuel rail pressure readings at idle then see what maximum figures you can get for the MAF, MAP, Intake Air Temperature and fuel rail pressure reading during a drive.
If you use Torque Pro, you can use the high/low gauges to record these figures.
@@sirobb Ok I will do as you said, thanks again for advice. But there was a misunderstanding, at the moment I have all 4 codes including P0244. I meant to say that on the last service I did not had it, but now I have it.
@@sirobb And just one thing, is that ELM 327 adapter, that I have, fine. Have you heard of any issues of it destroying the engine computer anything like that.
hi sirobb. You seem to have a lot of experience repairing Volvo D5 engine. My starts making this metallic noise after the oil is warm ( after aprox. 15min running), do you know the source to the problem?

Thx in advance
You can buy a new one for as little as £22 why would you bother trying to clean the old one. Not worth the time and effort
Why would you spend £22 on a new 1 when you can easily maintain the old 1. More time and effort spent earning that £22
Nope, no need to buy it :) if you clean the filter and inner part of this vacuum part it is going to work as new :) i just did that and after changing 2 mechanic not been able to fix my car son't know why i fix it whit this video. 3xcelent
will try to clean this emt thanks very much for your time and great video.
