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.

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

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!

Just subscribed because you've done a great job with this diagnostic...Have been running Volvo XC90 D5 for the past 7 years (on my third car now) and these are the best tips. great man, thank you

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!

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

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

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

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!

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

You are brilliant. Thank you for your videos. You are really helping alot of people. Thank you.

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

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.

Thanks rob, brilliant vid. The problem with professionals is, there not very professional and know everything about nothing.

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!

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

THANK YOU so much for your video you are the man my Volvo s60 d5 is fixed

Another brilliant video, I decided to check to see if mine had the popping issue and it dose, all engine mounts are new. I’ll be watching your other videos to try and locate the source of the issue! Thanks very helpful stuff

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.

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

Just bought a D5 and I'm really glad I've seen this, as mine makes the exact same noise. I now know what to look for! Thank you! =)

Genius videos, will create some work but save a fortune! Many, many thanks.

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

Lovely, thanks so much! And while the Volvo world might be small - you are one of the great..=*^) I'll check out the other video right now. Hope to run into you some time and be able to say Thanks face to face..=*^) Thanks again!

Hi sirobb ,kept most of your vids,very helpful,been in motor trade 55yrs,got this xc70 countryman diesel to sell 2 yrs ago with 229k on it one owner war and peace history ,now 235k as I couldn't part with it as it does every thing it comfort and ease,one thing I've had a go at to no success,engine check message,lack of power,checked most thing gave up taking turbo of to degrease the vanes as it looked a right job, I just drive and when it does it I flick of the ign and on again and carry on driving,worse when cold so I don't Rev it to much then,had egr off etc cleaned it all,inc top rocker box,some crap in there,thank gig for

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

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.

10 more years, and I'll learn to fix all parts of my 700K D5. Thanks!

Again, he's the man Sirob

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...

SiRobb,thanks for this and the other videos. I just find this noise in my s60. Temporary fixed for a screw. Need quickly changing the mounts or enough few weeks later? Thanks

Very usefull, thanx a lot. My problem was solved after your advice

I have same problem on my s80 2011 D3 engine and i asked to volvos service this problem but they said that this is normal ... i gonna test it if d3 have same vacuum system like p2 volvo. Thanks for great video !!!

Fantastic videos mate well done 👍

Absolutely brilliant tutorial videos Si, Rob, SiRob. Imo the very best Volvo tutorials on KZfaq 👍👍👍 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.

Amazing information! Thank you for sharing!!

sirrob i like yours videos its perfect.

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.

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.

Hello @sirobb Aside of the popping noise, the noticable engine clicking noise is perfeczly ok? Or it might be problem with hydraulic lifters? Thank you!

I have a D5244T4 engine on V70. Checked vacums-OK,checked and cleaned pcv-was quite clean and ok. Started to install rocker cover and discovered broken rocker arm,so one of the valves is not working so causing popping noise and massive oil leak. Rocker cover was removed to replace its seal. Broken rocker arm had made 10x4mm hole through cylinder head into injector socket.

Thank you for sharing the knowledge

Very useful video Many thanks ❤️

You sir are a star

Thanks for the information

Great info. Thank you.

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.

WOW WELL DONE FINDING THIS KNOCKING NOISE PROBLEM !!! I have bought 2008 xc90 d5 for my dad 3years ago with this noise. I knew then that it was something to do with vacuum but could not find what. Ever since it bothered me but now I know what it is and can fix it. Thanks

thank you very helpful 4 me how can i prevent the vacuum leak

Thank you for this video👍🏼👍🏼

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... "

My old D5 had this when i bought it, drove 100.000km with it then old it off to a new owner. never had any issues

Hi,you are too strong 🛠️👍 thanks my Friend🙏✌️

Sorry for asking dumb questions, but what part do you have to change if you have this noice and did the same as you did?

Don't ya think there could be a small african with a drum down there? I wonder if same goes for the petrol engine?

Awesome, thank much for the video!

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

Thank you very much

Top Man! Always wondered what’s the source of that noise when I opened oil filer cap on my D5’s XC60 and V60. Thank you for sharing

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

Thank you

Tank you . You are a smart one ! If someone is tell his self (specialist) don’t meen that is smart too . Sorry for my language

bravo...!!

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

Exact same symptom on my Euro 3 D5. Is this something that would be harmful for the engine to drive with over longer period of time, or is it just a concern or not while idling? Runs like a train, but I’ve started to feel signs of a bad engine mount when I accelerate and then let go of the throttle quickly (just to diagnose if it was the mounts or not)

Thank you sooooooooo much.

Thank you 🙏 ❤

Nice video thanks so much

Thank u for video, how to solve this problem?

Too bad your car seems not to have the parking heater installed. This component fails all the time on the up-to-2006 models. A repair and disassemble walk trough would be fantastic. Your video's are great!\

Brilliant thanks

Thank you!

Thx sir for this aweaom vodeo!I have on my s69 D5 low acc and issues over 2500rpm,and the error code is 6805.All happen ed when in one workshop cleaned my egr valve!

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?

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..=*^)

Top man!

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.

Nice done

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!

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.

Thanks

Hi there great video very helpful my d5 got same noise but mines 07 reg 186 bhp model . How much does the engine mounts cost to replace is it a big job thanks

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

Thanks!

Thanks for reply mate .mines is a euro 4 186 bhp

Hi ! Thks for your videos . I have D5 2008 on XC70 , i have popping noise like the video , could be the hodraulics engine mounts ? Or mi car dont have. Thks you very much.

good and strong car it is. introduce and describe your car😃

So smoke is perfectly normal for a d5 pheww. I've be maintaining mine like a crazy man. I haven't got the excessive popping noise but a bit of smoke from the oil cap. I'm running miller's 5w40.

Did think my self omg hes right. Is it out of oil I thought. Then couldn't find any dipstick!!° I'm an engineer an I've stressed out about this all night untill I've seen your vid. I think there is a few problems with the car but I'm now understanding what is going on without having to ask a main dealers help.. expensive and clueless

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

loving your videos, just got my first Volvo. Its a D5, mine is doing this, can I drive it with this issue? Worried pressure could build up and cause more issues.

i have same issue but when i cover the turbo control valve is still makes the popping noise. what else is there to check ?

OMG I HAVE THIS!😧 I have had loads of V70’s but never came across this before🤷🏼‍♂️ I am an engineer and annoyed i couldnt find what it was i have never heard of VACUUM ENGINE MOUNTS! I need to change my lower steering UJ before the MOT as its starting to feel ‘vague’ so its that. When its up on the ramps ill change the mounts. NEVER heard of any manufacturer doing this before, totally new to me 🤷🏼‍♂️ CHEERS SIROBB I was thinking big ends but the engine PURRS and is very pokey so not that?

Hi there can u tell me if am best to block the pipe of till I get mounts fixed .good vid 👍🏼

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

hi my d5 makes this noise but when i blank 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 happen. have you tried this?

went looking at an xc70 last week at a very reputable second hand dealer who told me this was normal , walked away luckily.

What if I plug it if for a mean time until we fix the problem. Would it do any harm to the engine?

Good info

Great video, with the issue explained easily. i just tested mine by squeezing the tube to close it from the side of my TCV and expected the popping sound to stop, although in my case it made no difference... what does this mean please?
