Volvo D5 Engine Popping Noise Cause and Cure

[@HULLC1TY1]

Hi sirobb ive Just bought a d5 Volvo S60 and it has this problem. Ive been looking through your videos you have posted and mine has most of the problems you have put up. Your videos have help me a lot and saved me money and headache from the wife as she thought I bought a lemon. Thanks again please please keep posting these realy helpful videos.

[@pacoporras8726]

Same same for me Simon... mine doesn't have all the issues though... But definitely you made a huge contribution to my pocket.... Thanks

[@geoffreygcotton]

Hi Simon, Hope you’re well, how are your swirl flaps?😮 I have problems with mine, wondered if there were any swell flap videos in the pipeline👍

[@ggtaruc2578]

I don't own a D5 but just wanted to thank you for taking the time to share this knowledge.

[@alexsa122]

OMG man !!! I was REALLY WORRIED about my D5 engine, because of this sound. Now, at 1 am, searching about the issue, I have found your video - and yes , I can tell that this was my problem. Thank you very much!

[@dansaabnut3563]

Had exact same problem, went on YT found your video SiRobb and everything is sorted now. I just had to comment beacuse you helped me effectively and quickly diagnosed this! Much much appreciated for your kindness and that you are uploading such videos! 2 weeks ago I was after W124 MB pre 1993 but I couldn't find right example so I changed my mind and luckily my Gold D5 2002 S60 with 65k milage came up on Facebook marketplace and I decided to give a go beacuse my head always turned around when I saw these cars and used to always liked them : D Same as 7xx series, 9xx, 850, and pre 2002 V70s. My car was bit neglected but I am giving her proper care now. Last week front and rear engine mounts, full service plus carbon cleaning, front brake pads, central exaust leak welded, Injector seal replaced, turbine refurbished and wheel alignment done. That's so far. I am gonna check all suspension as a next step and replace gradually everything which needs to be addressed. Feel good about that! I've got one struggle with interior though and it's driver seats. Because it's Velour ( I didn't want leather interior) the seat is worn and there are holes already in a stichings. Anyway this as well will be done! They such a great cars. They have this feel of 90s/80s and when you driving one no any other from any new ones brands will make you smile and there is feeling in you that you actually never will go for modern beacuse is there any pleasure to drive a soulless machine ? : ) I like as well idea that these cars proper maintained lasts forever not needing to be replaced and people by keeping them developing some sort of feelings towards them. That's true friendship beetwen the man and the machine isn't ? SiRoob have a nice day tomorrow and wish you all the best! Cheers!

This is What i call superb info from an Expert in my opinion, You have a lot of videos and i like them very much AS this is important and simple info, No volvo Dealer will tell you, at least not here in Norway (NoWay🤣) Keep up the good work!

[@snake802002]

Hi to you all Volvo owners! First of all i have to say that SirRobb is the Superman of old Volvo. Thanks to him i discovered why my old d5 made that strange noise when pullin off the oil filler cap. I can confirm that is a vacuum related issue. so, i noticed that when pushin hard the brake peddal the noise stoped. so in my case it was the power brake booster cause is related to the vacuum pump. the car was brakin just fine but sometimes the return of the brakin pedal was kind of slow followd by some air leak, like a wistle. Hope this info is usefull for those who didnt find anyother leak on the engine monunts or vacuum pump. Thank you SirRobb

[@AzzyAasbjorn]

Johnny Depp you mightve just solved my problem with the vaccum leak Ive literallt replaced all the lines and mounts but still get the noise. Going to try this tomorow too see if it works

[@goodziemusic]

Hi Johnny, I have just found a similar knocking noise after pulling off the oil cap of my C30 D5. It sounds very similar to this video but higher pitched. Can you remember if the sound from your engine was higher pitched? Would I be able to contact you and send you a video? I still need to check the engine mounts the same way this video suggests and also push the break pedal hard like what you did and see if the noise stops. Cheers.

[@Altarofwater]

Did changing the brake booster solve the problem?

Hi SiRobb Just wanted to thank you for the well presented & informative videos. I have recently acquired a V70 D5 and as a retired heavy truck fleet engineer I guess I would eventual get around to learning some of the stuff you have presented in such good tutorials. Very impressive. Thank you Dave

[@sirobb]

Well thank you too Dave for taking the time to comment. It's always satisfying to hear folk find my ramblings useful and welcome to the Volvo fold. ☺️

It's 3 plus years since I previously thanked you for your really impressive tutorials Simon and you continue to do some great stuff. Just wondering could you direct me to anything you have experienced on changing the Volvo HU-850 radio with another of same model coming from same year V70. There appears to be some sort of software mismatch, CAN bus issue and proving to be a nightmare. I don't have VIDA or DICE but would buy if a code change is possible. Dave

[@DomX2008]

You sure told the experts! Nice job, handy thing to know for D5 owners, many thanks.

[@777skinner]

You are so right about so called experts I know this through bitter experience. Recently I took my 2007 D5 to a workshop fir a crank shaft seal replacement, a 7-8 hour job listed in Volvo schedules of work. The workshop took the whole engine and gearbox out, split the two, replaced the seal, replaced the whole unit resulting in a car that would not run properly below 2k revolutions. 24 hours work, a car unuseable and they wanted £1400, and I bought the seal.

[@daliborsacaric5258]

Today I have tested this and had the same noice and same fix you show... But im comcern of your video I would recommend you to check your PCV that not excists and your camshaft Thank you for your Videos, Mate...

[@paulbird795]

I removed the brake booster vacuum hose from the vac pump and this popping noise STOPPED! Stick my finger over the pump inlet and the popping starts again. How contrary is that. Very good videos and much appreciated.

[@sirobb]

Use a vacuum tester and and check at different engine temperatures as the EGR position can cause the popping noise even with a sound vacuum system.

[@paulbird795]

@@sirobb That does make sense, thank you. I was having slow start issues with my xc70 and tracked back to the ECU not seeming to transmit a signal to glow plug relay, also the original volvo glow plug connectors were really craply done so I have just made a whole new glow plug relay and distribution system controlled by a NO micro push switch mounted on plastic panel near gear stick. Also noticed that when the coolant temp switch is removed, the car is fooled into thinking it's very cold so opens up fuel rack etc and starts immediately (sort of puts it into beast mode). So I have run that to a NC momentary switch next to the glow plug relay witch. One way or the other, that get it started! These are so well built, but sometimes a bit too clever so we have to rethink the electrics. Before I got it the history shows a fortune spent at volvo garage to fix glow issues, fab remedies like wrapping tap around the glow connections!

[@blackbox-communications4186]

Thanks for this, that was really helpful. I didn't realise my engine wasn't supposed to be as loud, and had really bad power loss on my motor coming home from holiday! Going to try this tomorrow and order new mounts

I own an D5 with engine damage cause I've a good engine to replace. Thr engine runs and To hear was this Noise (thanks to you i knew what it is) and a metallic hard noise from a defect top engine mount. a detective Glowplug prevent from a good start. So the previous owner had been informed by the workshop that engine damage was imminent and he sell it cheap. It's a shame what workshops tell his customers for a bullshit for the next order. Ok the dpf was full cause glowplug failure but I repaired it all and have a very good in shape v70 phase 3 for much less than good in state running cars.... Thanx again

Once again SiRobb does the job! My D5 is doing this and I know it is the mounts and I have a vacuum tester. But I actually think that pipe is not connected to the control valve on my car. I must check when daylight arrives!

Hey, SiRobb thanks for this excellent tip! Have been watching your Volvo videos for a while !! Absolutely great!!

Thanks for this video, had a very rare limp home mode issue and suspected a vacuum leak straight away and tested for this noise and have it, so luckily an easy fix

[@reynauldayson]

how did you fix it?

[@cooperwilliams4686]

Thank you... You are a Legend. 😉 Everyone on here calls themselves an expert 😂. Even the "technicians" At my local main dealer couldn't diagnose this noise for me. I did as you do in this video and problem solved. My engine mounts are fine but the vacuum hose had come disconnected... Probably the last time an "expert" had his hands under the bonnet.

[@aaronpostlethwaite8449]

Thanks for this video. My V70 has this same issue . Why do the engine mounts require a vacuum?

[@tryku4285]

I also have a vacum issue with my D5. The noise doesn't go away even if I block the connection on the vacum pump itself. May this be caused by a leaking brake booster? I already have changed the O-ring on brake boosters plastic connector.

[@gasgiant7122]

Absolutely brilliant tutorial videos Si, Rob, SiRob. Imo the very best Volvo tutorials on KZbin 👍👍👍 I have just bought a XC90 with 105K miles with enjoy popping, now I know it's nothing really, the other thing is a rattly noise from down by pulleys on idle but when rev up it goes, I was thinking it could be air con pulley? Can I replace the pulley? Cheers.

[@albertje]

Thanks for the video. Had the same issues with the sound coming from the filler hole. Also people said it was a crankcase ventilation problem but ventilation was all clear... Gonna check the vacuum hoses tomorrow. I already blocked the engine pads a long time ago so it could me the lines to the turbo.

[@NerminZahirovic-k5p]

hello, if you plug the hose in and the sound goes away, it means there is a leak somewhere, if the sound is knocking, it means there is no leak or

hi my d5 makes this noise but when i bloke the brake servo hose and the vacuum hose from governor, the popping noise stops completely. dose that mean my brake servo is faulty. no leak on vacuum pump. i blanked the engine mounts but noisy still

Well that’s Amazing ! Who’d have thought that noise in the engine was an engine mount outside the engine !

[@marksquires1112]

quick ? Rob, why do engine mounts need to be supplied with a vacum? So interesting, and forgive me if it`s obvious but i am not very mechanically knoweldgeable to be quite frank. Thanks for all your videos, i have just bought a d5, 2006 model, and seeing this wealth of info you have shared with us has helped me decide to purchase this car.(my 1st Volvo!!) Still gotta go fetch it, so have only done a test drive thus far, but what a car is all i can say for now. :)))

[@sirobb]

The vacuum softens and hardens the mount to improve engine damping and reduce cabin vibration.

[@marksquires1112]

thanks man, you are great to bother replying to me. My son in Germany googled it the other day when I was chatting to him and.I'm happy to hear he is right!😊 Was wondering how long I can let it go on for, any danger to the turbo I hope by leaving it for a while? These motors fuel economy is allegedly 6,5 l per 100km(i think-its the d5) but with a well serviced engine and driving responsibility(mellow acceleration etc, I am an experienced driver) I'm wondering what kind of fuel economy I should expect. Any idea here Rob? (It might be a good indicator of excessive vacuum leakage from those engine mounts..) No worries if its asking too much, but if you have some idea, I'd appreciate some insight here. Cheers Rob.

[@brendanobrien5842]

Mate your a star. I just bought a v60 es 63plate and I've not had a Volvo before. Lovely ride o ly done 60 miles but theres a hissing noise like a turbo leak or inter cooler leak ect Dose seem propper sluggish but I've been that busy mot had ti e to look. I just tonight opened the oil filler cap and heard this load popping noise and my neighbour who was 50 ft away said "oh that's fucked get rid of it... "

[@henke100]

I have this issue as well as many others apparently. I found that unplugging the electrical connector on that valve closes it an the popping goes away. Since you call it Turbo control valve, does it do anything else than provide vaccum to the motor mounts? I am thinking that I will leave it unplugged until mounts are replaced, good idea? Thanks for this good information!

[@TIvesmusic]

I agree - Fantastic! mine does this! I nearly walked away. So glad I didn't. Best wishes Tony :-)

[@dougedwardsyachts]

Hi Robb, interesting video. I think in 38yrs of driving I’ve never undone my oil filler cap whilst the engine was running. Of course I now have on my recently purchased winter ride 04 V70 D5 😱 the popping sound is there on take off, car drives well otherwise. Hopefully it can wait until the Spring when my Summer car comes out again.

[@olle209]

Hi SiRobb, I have a XC70 D5 2005, got the same noise when opening the oil filler cap, WIll try to remove the hoses to the engine pads, I also agree it is a vaccum issue, my question, I was probably stupid when I blew compressed air into the hoses after removing the hoses from the TCV. Do you think I have damaged something with the compressed air. The turbo is not working anymore but that could be linked to being clogged with oil sauce after the oil cooler broke. Thx and best regards from a Swede living in Germany having three Volvos. XC70 D5 , V70 GLT 1997, S80 V8 2007 with Heico sport exhaust.

Sirobb do you actually know how the loss of vacuum is causing that popping sound. Obviously, it is a vacuum issue and my D5’s popping noise is even louder than yours so I am just trying to understand what exactly is popping in the engine. Many thanks!

[@christopherhaga2388]

Hi. Great videos! I've tried cleaning the tcv an blocking the pipes all the way down to the pump. Blocking the vac pump wont help. It seems as there is a lack of vacuum. Testet it with a vac gauge. The vacuum comes in pulses, and it wont build up, it just flickers. Removing the maf makes it even worse. Thinking its the vac pump thats broken. Just wondered if there are any other things I can check before I get a new one? Can't see how the maf sensor has anything to do with vacuum the pump produces? I have the EURO3 Christopher

[@sirobb]

See my video here kzbin.info/www/bejne/ZqvWepRqjpeHmdU and put the vacuum tester directly onto the vacuum pump. If the needle flickers and doesn't stay stable, the vacuum pump is faulty or the vacuum pump seals. Buying a used pump should be quite cheap because they are very reliable so not in high demand.

Just got a d5 & thought I'd test this myself but someone has disconnected both the hoses from the mounts. I have this noise but can't figure out where it's coming from if both mounts have been disconnected. No fault codes on the car when driving it does make a turbo noise I'm guessing that's normal though

[@stevyspilliaert2159]

Can you explain why the engine mounts me CREATE noise in the oil filler cap ? Is the breather operates on the same vacuum system ? Sorry for my english

[@knoraffe]

Hi SiRobb, maybe you can help me ;) i have test it on a car i want to buy but the sound hasn't changed. On a test drive the brakes doesnt work like they should. I think the brake booster is the problem. Less power too at the acceleration. Could it be that the vacuum pump is defect and thats also the reason why it has less power? Also there is smoke coming out of the dipstick. Greatings Albert. I hope you can help me cause you know more about the volvos than the volvo mechanics.

Hi Sirobb! i had the same problem. the popping went away by isolating the rear mount- changed the mount and the popping is still there. The line itself holds preassure. Im stuck now. One volvo garage told me that they have seen many euro 3 engines that have this popping that goes away by isolating the rear mount even when the mount itself is fine. Is that true? is the rear mount supposed to leak some vacuume?

The rear mount could be perished and releasing vacuum and replace the vacuum hoses

@@abood_abtv4203 In the end i ended up swaping out both vacuum actuated mounts and vacuum hoses and the vibration in cabbin got even worse- transmissions tarted touching the subframe at times so another independent garage swapped out all 3 rubber mounts (for Lemforder) since they all were perished and only then found out that the new "Febi" vacuum mounts were both shot (assuming- defected from factory or just designed badly") and leaking oil when removed for inspection once again. Got "Lemforder" ones and all the vibration and popping went away.

Hi SiRobb, I don't really understand if you will see this or not but your video about the popping sound is very useful. I have a Volvbo V70 D5 Turbo. I have been losing intermittently the turbo. I have now discovered that I have the popping sound and it goes when the boost control valve is blocked as in your video, I am replacing the engine mounts and tubes and as the same vacuum operates the turbo I am really hoping the problem will be cured. Cheers. Any advice you have will be greatly appreciated. I'll let you know how it goes.

[@sirobb]

Thank you. Have a look through my videos. There's more available including changing the engine mounts. Good luck. 👍🏾

[@VIGtony]

Do you think that the vacuum loss would be enough to make the turbo boost not work intermittently Cheers

[@sirobb]

@@VIGtony Depends on engine. Euro 3 D5244T - vacuum loss affects turbo operation. Euro 4 D5244T4 onwards with single turbo - vacuum loss does not affect turbo operation Dual turbo may be affected. Basically, your exact engine determines likely problems and the relevant fix.

[@mari-fq6it]

sirrob i like yours videos its perfect.

[@danwilson38]

Ok so I’ve got it the other way round. When I hold my finger on the vacuum pump I get the popping noise. But when I let go it is quieter. I’ve got a thudding when it’s idling and other people have said it’s the mounts but it’s the opposite to this video

[@stoatlover]

It appears my front engine mount is nackered as I have this noise and when I block the line to the front mount the noise stops. Can I block the line temporarily till I get a new mount? To stop the vacuum and I guess boost leak when the manifold has positive pressure?

[@sirobb]

Yes. There's a temporary fix video in my list. You can also vacuum test the mount to confirm.

The popping is vacuum related so because that check hasn't worked for you, have a look at the boost solenoid cleaning video in my list. That's assuming you have the Euro3 163.

+SiRobb thank you. i do have the 163hp model. so will check out your other video. is it the Cleaning Volvo D5 Turbo / Boost Control Valve?

[@sirobb]

+Richard Roberts Yes that's the one. 👍 You can also peel up the metal rim and remove pipework and inspect the rubber diaphragm to check for splits.

Hi Sir Robb, What is the sensor on the far left on top of the engine - to the right of the oil filler? And what does it connect to? Love your videos and follow you on Volvo forums..=*^)

[@sirobb]

Christerart1 Hi. That's the MAP sensor. It's location can vary dependant on your D5 model year. Explained in my very short video here kzbin.info/www/bejne/e32bmZ6IiMRlgq8 Thank you for your support and yes I recognise your forum username. The Volvo world is a small one. ☺️

Nobody can explain why this makes noise in the drain plug ? I try to understand , but I do not understand the link between the media and the sound of oil cap

You sir are a star

OK, brill video and thanks for being helpful, but i've just put my finger over the hole and i felt the vacuum there, but no matter how long i held my finger there for the noise didnt get any quieter. What does this mean?

[@sirobb]

If the noise is there at all engine temperatures, you need to further investigate the valve and vacuum system ideally with a vacuum tester. Lots of videos in my Playlist called Cars.

Anche io se tolgo il tappo fa questo rumore...quindi devo cambiare i tubicini?

[@mukie1988]

Hi mate I have the same popping noise coming from my D5. I have tried the same thing you have done but it's still popping. Do you know what the issue could be?

[@tonyspudcallycally7066]

Wow just started hearing this slightly every now and then I have the 2013 p3 205 hp twin turbo is it possible for this engine or are all d5 s basically the same just different turbos etc

[@gokublack337]

I need help on my XC90 hydraulic lifters clicking were are can u help

[@niekschroten9282]

SiRobb, thanks for your great video's! I have the same noise (D5 XC70 2004), but when I do the same on the turbo control valve , the sound does not stop. I do feel suction from the Turbo control valve (as you demonstrate on the thing on the air filter), does it mean I have a leakage at the TCV? Any idea?

[@sirobb]

Niek Schroten See my video here for more testing kzbin.info/www/bejne/Y53KinSJaKyin6c

[@niekschroten9282]

Thanks!

[@markberends3259]

I Simply cant find the TCV on my Volvo v60 D6 from December 2015. Anyone knows if they changed parts or location?
