Excellent tutorial video Simon. I kept having the "Engine Service Required" message coming up on the display. Now diagnosed as leaking engine mounts, I've temporarily blocked the outlet pipe from the solenoid which has stoped the message and improved performance somewhat due to having full vacuum to the wastegate. 😊
Just wanted to say thanks for posting all these videos & sharing the knowledge. Not got any real problems with our 191k S80 just yet, but it's still interesting to learn how the thing functions. I'm more acquainted with older cars (Love my old Citroen diesels) but very quickly becoming a convert to Euro3 D5 power the more I spend time in/on the car. Cheers, Dan. ("ma70" on the forums)
Woa thanks, my S60 D5 i recently bought was slow, i tought it was because an old man used to own it. I checked the vacuum hoses and discovered one was ripped in half, after i fixed it the turbo boost came back.
Hello. A piece of advice if you would. Volvo V70 D5 163ps. 167miles. Tick over fine. Car lacks power. Maximum speed 80mph takes a while to reach this. Hard acceleration produces no wheel spin or acceleration kick even on gravel surface. Popping from oil filler cap area whencap is removed. I have checked all intake pipes from air filter to engine. EGR valve not cleaned but pipes you removed in this video is clean. New DPF. What do you believe is the problem.
Your clear explanations are very much appreciated. I have a popping noise when I open the oil filter cap on my Euro 4 engine. It doesn't seem to affect performance and no error codes so far but I think I need to start doing more investigating.
Very likely to be the PCV system. Other than that, could be the Hydro-thingys controlling the valves (don't know the English word) and last but not least, the pistons themselves, which of course would be the worst options.
Excellent video as usual, your content is of great value. Slight correction or maybe additional information ref later models, the 2.4D variant has a further vacuum feed to control a bypass valve in the EGR system, fed from the sub 1500rpm actuator by the air filter - same circuit as engine mounts. Have not quite worked out the normal operation but I think it holds off the bypass below 1200 to 1500 rpm until the engine is warm, which makes sense as when one of my engine mounts failed and I was losing vacuum, my V70 would often stall at the end of the road, but never further on as the engine warmed. I think this system is for manual transmission only, not autos. E & OE !
With maybe 20+ D5 versions, it's impossible to do a concise video which covers all possibilities but yes you can add your findings and experience to the list. I recommend that every Volvo owner has Vida to make use of the extensive Design and Function section for explanations of the different systems in one's individual car model.
@@sirobbthat is a good point, however I have found that vida skips many details especially when you only wanna swap a small sub-part not the whole unit (for example the Orange vacuum pump sealing insert costs a few dollars but Volvo wants you to relieve the whole vacuum pump which is criminally expensive).
This was an informative video thanks for sharing. I have 2005 Volvo s40 d 2.0 (hdi engine.) in the front of the engine where the manifold is, I have accidentally knocked off the vacuum pipes and have attempted to fix this but to no avail. There are 2 inlets on the solenoid attached into the engine under the manifold, 1 sucks (or blows) in and the other doesn't. 1 is on top and the other is just below it and they are close together. I am having trouble rearranging the 3 pipes (with a t attachment) to go to which pipe attaches to which pipe, and where then the 2 pipes would go into the solenoid. I have searched the internet and found your explanation and if you could help me with my problem, I would be deeply grateful. 1 pipe comes up from underneath. And the 2 remaining pipes come from the right of the engine bay. If you could help, many thanks
Just replaced all my mounting and checked all the vac pipe work, all okay except I found a small length of electrical cable about an inch inside the boost Valve pipe supplying vacuum to the front and rear mountings, replaced that completed pipe but can still hear the popping sound on idle at a loss as to what is causing that still, the engine has it grunt back and loads of power compared to before the mountings replacement
Thanks SirRob!! Watched most of your videos, clear and articulate explanations. Very grateful i found your chanel! If you'll read my comment and have time to answer my question, I will be honoured. Have the same engine, eur 3 163hp on 2005 xc90 aut. No codes, except Air quality sensor is faulty.. Anyways, when i push the gas pedal, from cca 2200-3000 rpm i will get acceleration in steps (rpm will rise to 2300 rpm drop to 2250, go to 2600, drop to 2550 and so on, maybe 3 steps from 2200 to 3000rpm... Hard acceleration, or going uphill will be felt more), but after 3000 rpm it will accelerate normaly, maybe a bit sluggish.. Anyways im not trying to tickle your brain just wanted to ask you whether you think it could be related to vacuum loss somewhere in the system.. As Ive said no codes related to low fuel pressure.. What ive done: Changed fuel filter Cleaned boost solenoid with your video Tried to find PEM, can't find it, or havent happened to come across it yet as of today. Cleaned all contacts on fuel pressure sensor. Im quite lost, everything else works as it should.. (I should add that it is more noticible when car warms up) Im picking my brain real hard, Anyways, if anyone has some input what to check will be very gratefull. All the best and cheers, Very happy owner of my 2nd eur III d5.
I have a XC70 D5 AWD, 2010, have the ticking sound out of the oil filler cap (metal to metal sound), normal break function. Unsure if I have the solenoid, cannot see a turbo control valve.
I am really curious about this system in the D5 Euro 5 engine with the 215HP Twin turbo 2.4L in the S60. It all very difffrent from the previous D5s and i cant find any tutorials on the newer D5. Its really frustrating. Would be great if some1 could help,
Hi SiRob what RPM does the vacuum get removed from the turbo actuator as I have a fault that the car is a little sluggish. could it be the boost solenoid if so how do I test the boost solenoid. I have found a leak on my front engine mount which I will replace but still think there may be a issue with the solenoid. could you advise how to check the control solenoid. Many Thanks
I have a 2003 xc90 D5 euro3 and I have the popping noise and when accelerating from 0mph there is nearly no power and the when the turbo kicks in then it's fine. Could the problem be with the vacuum system?
Heey Rob. Great video thanks. Question about the popping noise, i have blocked the engine mounts. But still have the hard popping noise. Can the vacuümpump leak internal to the engine?? When i pull the brakeboosterline popping noise stops, when i install it again loud popping noise starts again( same sound as leaking enginemounts) thanks in advance
Hi Nice explanation! My t6 has a whistle noise after the engine warms up and only at idle. It disappears after pressing gas paddle. It is unrelated to braking or not. Sounds like air suction. I have replaced pcv and also vacuum pump seals. Nothing changes. I suspect something related to throttle body closing. Is vacuum related to it? Many thanks!
Hi sir, v70 2007 d5 when warm i loose all boost IF i have revs under 1500 and gets in to boost, IF its over or hits 1500 before peak boost it works well, No cel .. when Cold its better and doesnt cut boost all the time. What should i check? Nothing obvious in Vida
Great video I have the popping noise from my late d5 xc90 2005 should I be tracing engine mounts and vacuum pump leak and not the pipes to the front by the CSI? Dan
Hi Sirobb, great job with all those explanations! I have one speciffic v70 with d5 engine, and i have a question related with turbo, meaning do those engines have some king of bleed-off valve? Asking cause this car i am interessted is making sound like BOV when getting from high rpm to idle and, honestly, don't know if it is correct. Can you help? Thanks :)
Good video, thanks, but is that value called Turbo Control Valve when it only controls vacuum to the engine mounts? My D5 got oil in the vacuum line to the waste gate?
Thank you for your great videos very informative, I have a Volvo V70 d5 and it's done nearly 200000 mile and I have black smoke behind me when I kick down, it looks like I am going to have to clean the EGR, Also I have never changed the transmission oil and I have had the car nearly 17 years, is it a big job to change the filter inside the gearbox ? She has been a great car,. Are there any other jobs you recommend doing at this mileage
SiRobb do you know the best way to test it? I’m connecting vacuum pump to input and covering output. It doesn’t hold vacuum. Was using 20inHg. Should I try less inHg?
thank you for all your videos. I have a problem which no one is able to help with. in My D5 Euro 4 (V70 2006), the vacuum line after the T (the one that goes towards EGR mixer) shows some oil. cannot seem to find the source but it seems to be from the vacuum pipe which I thought was not supposed to have oil but vacuum! Even before the leak appeared my car showed warning of 'engine system service required' and car had lost power (esp from gear 3 onwards). I cleaned the EGR mixer with Wynn and the performance seemed to improve but this oil appeared on the vacuum line which is feeding on to something near the EGR mixer. I cannot seem to get the warnings to go. If you see this post, please can you help me?
Same here, 2005 d5 auto. Think the garage over filled the oil on service (revised volvo service states no more than about 5.5ltrs or below the 3 Xs on dip stick. Think it's travelled through the system done how like yours.
I have a quite complicated question, maybe you will know how to answer. As far as I've understood, the turbo geometry is controlled with vacuum in a way where: More vacuum -> tighter turbo geometry > more boost. Less vacuum -> looser turbo geometry -> less boost. So while the engine is at low RPM, there is maximum vacuum to ensure responsiveness of the turbo. When car accelerates and reaches higher RPM, vacuum is reduced and turbo will slow down a bit to avoid damage. If an overboost condition happens, the vacuum is reduced to 0 and VNT drops, completely loosening the turbo geometry and reducing boost. But here's the catch - with increase of engine RPM the vacuum shall increase as well, but for control of VNT the opposite behavior is required. Does that mean the boost control valve actually controls vacuum variably instead of in On/Off fashion? It feels weird to think that a solenoid is used for variable actuation, because in industrial use solenoid valves are always used in a binary fashion. I am currently trying to figure out why my car drops VNT when accelerating, seems to be an overboost condition, but it helps to understand how the system works completely - maybe my VNT is sticking or some vacuum is leaking that leads to overboost at inappropriate RPM's.
Hi Simon! I had one question about popping noise from oil cap. When I remove hose between vacuum pump and brakes main cilinder - noise come off, but when I plug hole with finger or put hose back to pump, popping noise is back! The part with VNT and motor mounts is fine , i have checked it with hand vacuump pump. What is my next step to find problem?
Check the seal on the brake booster hose. Also check for the popping noise at different engine temperatures as it can go away once the engine is fully warmed up.
Do you know why the vacuum system relies so much on the engine mounts? I had to clean my TCV and replace the engine mounts, and voila... feels like a new car, got my power back :) but the onboard computer didn't told me anything about it, not even a generally: "Check Engine" or something...
The engine mounts are supplied vacuum until around 1000 rpm so when you change gear, if the revs drop to around 1000, vacuum may be diverted to the mounts to reduce engine vibration BUT if your mounts are leaking, your system loses vacuum and the turbo actuator can't be controlled correctly at exactly the right moment. This is only on the Euro3 163 D5. Performance on the Euro 4 isn't affected. You can either fit new mounts or block the pipe that feeds the mounts so no vacuum is lost. You made the right decision to replace the mounts.
I have a problem with my s60 d5 euro 3. When I revving the engine when parked revvs are going up. quite slow. Same when I driving there is nothing happen until 2k rpm then turbo start kick. There is new turbo installed and cat back system + car is fitter with rica stage 2 ecm software. I'm sure i have a leak somewhere. Thanks
@@sirobb thanks. I appreciate. I was told that it was swirlflaps. Well at the end i removed the injectors and refurbished them so after this this d5 will go like new

Every turbo engine needs to have a blow by valve otherwise there be a chance of to much pressure building up
Good video, thanks, but is that value called Turbo Control Valve when it only controls vacuum to the engine mounts?
My D5 got oil in the vacuum line to the waste gate?
Turbo control valve is a generic name because most of the time, this type of valve controls the turbo boost pressure when used on other cars.
What is the purpose of a vacuum in the engine mounts?
Cheers Pat great videos

The vacuum is from the vacuum pump. The engine has nothing to do with it.

Could the brake booster cause a vacuum leak and then cause the pooping sound
Yes, either the booster seal itself or the booster vacuum pipe seal are the most common.
