How The VW 2.5L Vacuum Pump Fails ~ Video

[@chrisleblanc6597]

Dude…………DUDE!!!!!!!!!!! Got the seal kit on Amazon for $9.99. Only replaced the outer seal without removing the pump. All lights and problems are gone. You gave me the confidence to save myself thousands of dollars! Great video!

[@AfternoonProductions]

How long did that last? Mine failed again after not even 6 months. Installing the Spulen vacuum pump delete kit today 😝

[@boomerguy9935]

Wonderful info which is perfectly timed for me. I just bought a 2008 VW Rabbit 2.5 and when I changed the oil (another learning experience with the oil filter cartridge, but I digress....) I noticed how wet it was above the side of the engine/transmission connection. Rather than panic, I went to KZbin and found this excellent diagnosis. Then I went to the top of the engine with a flashlight and sure enough, I could see the oil lines running from the screws which hold the plate onto the vacuum pump. Since I've already changed the engine air filter (another unique VW learning experience, sorry for digressing again...) I know how to get past the first challenge. The car has been taken care of by a very meticulous owner and I am very happy with its performance and quality which hide the fact that it has over 145K miles on it. Thanks again for the info. Time to order the gasket.

[@DerKooze]

Thank you soo much for this video!!!!!!!!!!!!!!!!!!!!!!!!!! I have a manual 2.5 Jetta and the dealership just told me 1400 to replace the vacuum pump because they have to spend 7 hours removing the transmission to replace the pump. THANK YOU THANK YOU THANK YOU. I knew the guy at the dealership was being weird. Now I know why.

[@DerKooze]

Just an update. I spoke with my friendly local VW certified mechanic shop. Vacuum pump replacement is literally three times cheaper than the dealer quote.

[@HumbleMechanic]

Yeah the manual labor is almost nothing. Lol

[@DerKooze]

@@HumbleMechanic I called out the guy at the dealership on it too. He had nothing to say. You have no idea how relieved I am. You got yourself a fan. Thank you again. I love my jetta and was worried I was going to have to sell it because of this. Not anymore!

[@iddospage3280]

@@DerKooze do you have an Automatic Transmission?

[@DerKooze]

Na-Na & Romie no. My OP states I have a manual transmission

[@justinrobinson4582]

Great video!!! You don’t have to separate motor an trans. Simple way to get it out is to remove battery compartment an take shifter lever off. Slide the black plate out an the pump will slide out over on to the shift lever bolt an come straight up

[@korihines12]

More 2.5 videos please

[@HumbleMechanic]

anything specific?

[@korihines12]

HumbleMechanic Just general facts and common problems. Its very hard to find videos for the jetta and rabbit around. All you really see are TSi and FSI repair and performance videos. You do very well at explaining things it would be interesting to see what depth you could go into with the 2.5

[@HumbleMechanic]

Cool. I'll see what I can do.

[@missouribrickie5010]

Yeah 2008 VW jetta 2.5 leak detection pump!

[@maxinare]

Sorry to highjack but in South Africa and have a vw t3 microbus 2.6i 5 cylinder and need more info on these engines , have encountered lots of issues from engine low pressure buzzer to oil in my exhaust

[@djc6394]

Thanks for the videos. I have had a lot of VWs over the years, but hadn't had one in a while. Most of the cars I've worked on have been far older. It's great to have someone else's knowledge to short-cut diagnosis. I got my daughter a 2007 Rabbit and I've been doing a bunch of fixes of minor problems on hers. I found you while looking for a comprehensive video on replacing the door actuators. I recently replaced the hubs because of noisy and worn out bearings (seemingly another common fail point on these cars). Afterward I noticed that the car was leaking a fair amount of oil (unrelated to the work but that's just when I happened to notice it). I had noticed before that the oil leak seemed to be around the transmission end and assumed that it was likely a rear main seal. I am hoping you are right and that it is this pump. Hers is a manual transmission, so I'm pleased to learn it is easy to replace, too. Anyway, as someone else said, I would appreciate more videos on the 2.5l motor...common fail points, fixes, things to look for, etc. I actually went for the 2.5 instead of a GTI because I didn't want to worry about a turbo fail. I was hoping this motor would be more reliable...

[@CS-hy6es]

not upset that you are 'fiddling' you know your business its respectful to us because you know what you are talking about thank you.

[@anibalcarbonell5818]

Charles, when to dealer for service and they said has a min leak, oil around gasket only. What do you recommend? Replacement or the delete option?, Car has 90k 2012.

[@jbr_cava]

I was quoted over $1k twice for this repair. I live in a city with no driveway and no tools and little experience. Currently, I'm on travel in WA state and after watching this video I looked up"vw expert in moses lake, wa" and Autometrics came up. I called in and they are VW experts. I dropped in and the head mechanic checked out my car, was really familiar with the issue and said that there's no way it's required to drop/move/disconnect the transmission. So, for me, the solution wasn't to DIY was to spend the couple hundred to let a professional get it right. Definitely worth it too as I am on a road trip and the car is losing oil pretty quickly (about an half court every 1000mi). With the money I saved, I went ahead and had them replace the dogbone bushing (common fail) and a few other things.

[@partyof5creations]

I know this video is old but man are you a money saver! I watched it once and went straight to work on my daughter’s ‘06 Jetta this morning. Only took a couple hours start to finish. Thanks!

[@HumbleMechanic]

Awesome

[@atarnofsky]

Yep we reseal them all day long with the black vw silicone. The white vw silicone sucks. Ive done atleast 50 reseals and only one has come back probraly due to it was one of the first ones i did and did allow proper drying time foe the silicone. But it works if you clean everything nice and just take your time. Pays good.

[@miamivice80s]

did you leave the original rubber ring? where i work we sell o-rings can it be used too? or is better leave the original rubber and add sealant?

[@atarnofsky]

+miamivice80s the orange o ring? doesn't hurt to replace it. the key is the silicone and properly installing the cover back on by hand

[@DiscGolfinSOB]

Need to team up with Deutsche Auto for a DIY on this, at least for the manuals.

[@HumbleMechanic]

That's a great idea. :)

[@dtownyogi]

Thanks for the detailed explanation. I'm sitting in the dealership getting this fixed on my 07 Jetta now. Its good to know why it fails and what exactly this costly repair involves. I second the thank god for extended warranties sentiment. Saved me over $600 bucks today.

[@HumbleMechanic]

dtownyogi You are welcome. I love when customers have extended warranties. It makes every one happy :)

[@ariaanalvarez4229]

Thanks for the video, I dropped the trans,auto, thinking it was a rear main, and after assembly I still found a leak. Thanks again for your videos.

[@scottlinder2258]

I opted to go this route instead of spending the $200 for a whole new pump. On a 2008 Beetle w/ Manual, I was able to get to it while in car. Put some shop towels under to catch the little bit of oil in there, popped the outer cover, cleaned surfaces well, installed new seal and buttoned everything back up. Cleaned up that area of the engine and will keep an eye out over the next few weeks to see if that leak is still present.

[@randolphmarshall5634]

Did the leak stop?

[@CashMoneyBowTie]

I just put the vacuum pump delete kit on my 2012 passat 2.5, i let it idle for a few, turned it off, went inside to clean up, came out to drive off & my "oil pressure low engine off" light came on. Did a fresh oil & filter change as well. Any suggestions. PLEASE HELP!!!

[@HumbleMechanic]

I have heard of some of the cover plates causing this. Some were made with out the proper oil path. I am not sure that is your issue, but it's possible. Id also look to be 100% sure your oil change was done properly.

[@shadowwolf74]

You must have been reading my mind, I was curious as to what failed on these. I noticed on my 2.5 that every oil change there is a little bit of oil coming from the pump. Not bad enough to get on the driveway yet so I'm holding off till then. Luckily I have the manual so replacement looks easy.

[@HumbleMechanic]

***** the manual is SUPER easy.. You will spend more time cleaning than you will replacing.

[@Montery12]

A couple of threads here generally mentioned moving the transmission to get to this vac, is that true?

[@munecodpapel]

that is unnecessary

[@yueibm]

Do these pumps have a check valve somewhere inside? On my Cayenne it's burning massive amounts of oil if I don't plug the vacuum pump from the rest of the vacuum system (oil being sucked from pump to intake)? Thanks for another great video!

[@raider762]

Thanks for the video. I work at a Toyota dealer and got assigned a Jetta as a used car. It is leaking oil from the vacuum pump. Lucky me it is a 5 speed manual.

[@jimbo0411]

I did mine today, it was a royal pain for me since i am no mechanic but a shade tree with a few sockets and thats it. I followed the how to video. Took me several hours and a sore back. I have a automatic so the worst part was after i replaced the gaskets trying to get that pump lined back up in the right spot, pretty frustrating it took me multiple times to line back in the cam shaft in that tight spot.

[@jhulbe]

You mention it's easy on a manual transmission. Just move a wire harness out of the way. Am I looking at this from a top down, or bottom up route? VW quoted $750 to replace it for me. Am I pulling the battery and pulling it out that way?

[@HumbleMechanic]

Yep. you have to remove the battery and tray as well as the switch on the trans.

[@jhulbe]

HumbleMechanic thanks man!

[@kashwashwa1]

Is this very common on the 2.0T? Is it relatively easy to replace on the 2.0T FSI with manual trans? I think mine is leaking, I've been having idle problems for a little while and today I lost power brakes - they eventually came back though.

[@HumbleMechanic]

kashwashwa1 Not as common on the 2.0 as the 2.5. You might want to check out this video. It is more likely the issue you are having. kzbin.info/www/bejne/noKolJynh5aGipo

[@timelessforever]

First of all thank you, great tips. I have one question; do I need to see oil inside the unit right after opening the front plate? Or has to be dry!? I have stripped 3 o’clock bolt and don’t wanna bother with it if the front gasket is all that I need.

[@BarbaritoAdolfo777]

Hi Is possible that a non attended vaccum pump oil leak can clog with oil gum the ckp reluctor or the ckp itself to the point it no longer reads accurately? My 06 jetta has p0315 code ,already fixed the oil leak,noticed when working on it that oil could reach sip trough an inspection port on top of the transmission cover,so i guess it may be the culprit.

[@chrisbender8491]

Hey first I want to say thanks, it great people help explain these things so much appreciated sincerely. I just had a dealer tell me I need to fix this leak, although I have no signs of it anywhere, they said if you don't it could lead to a very bad accident. Not sure about that, but I have no way of knowing and the price they wanted to repair was 1400$. What??? I was shocked. This is like transmission work prices.....

[@HumbleMechanic]

You're welcome. $1400 is pretty high in my opinion. they are probably charging you full labor time. We give our customers a heavy discount because the labor time is high. You very well may not see any oil on the ground. Most of it will get caught in the belly pan. I'd get another quote if I were you.

[@MRJONJMUSIC]

This may be a stupid question sorry in advance.. If I add a bead of silicone to reseal do you suggest I take the original rubber seal off and start fresh with the silicone or add the silicone on top of the seal? Btw thanks for your videos they help out a lot..

[@HumbleMechanic]

I would do it that way. But that may not seal the pump. The oil should not be getting that far into the pump. It may be worth a shot just be careful how much sealant you use

[@MRJONJMUSIC]

+HumbleMechanic so pull out old seal and add new bead? If that doesn't work I save to buy a whole new vacuum pump off ur suggested link

[@nicovg8119]

Hi I have a question for you , I have a leak in a VW Jetta 2.5 , it is possible that the leakage is causing the automatic transmission working poor. It is possible to seal it? What would be the best sealer for that. Thanks in advance and keep up your good work

[@HumbleMechanic]

Nicolas Vico I have seen transmissions leak causing issues. They can leak from the connector. If that is the case, the best thing to do is, replace the wiring harness. Not a super easy task

[@QPC_LLC]

So is the actual failure with the shaft allowing oil into the vacuum cavity then? Or is there supposed to be some oil in there and the seal just isn't doing it's job?

[@30awar]

[@MCKW-MTB]

I have a lot of oil in my charge pipe on my BHW 2.0 TDI. Could that be from my vacuum pump? I know my pump is different than the pump in this video so I'm hoping my oil accumulation is from the pump and not a bad turbo seal.

[@j.enriquez]

I have three questions: 1) Is there supposed to be motor oil inside the vacuum pump? 2) If there is supposed to be motor oil inside the vacuum pump, and I have a slight leak on the flat wall side of the pump, does that mean that the pump still works and a simple gasket change will fix the issue? 3) Should there be a marking on the inside of the flat wall hinting of metal to metal rubbing?

[@lxssard]

Hey Humblemechanic you know if that comment earlier about the vacuum pump. I had a question for you. On the same vehicle 2009 Jetta 2.5 l is throwing two codes. The first one stored is a P2178 rich off idle code, the second one set P0491 secondary air injection Bank 1 insufficient flow. Just wondering if you had any vehicles come in with these type of codes in any cures for them. I had a few others with the EVAP and other systems turned out to be some freed wires near the back of the vehicle also replaced the secondary air pump with an aftermarket changed the inline pressure sensor from the secondary air pump put in upstream O2 sensor put in evap valve and EGR replacement diaphragm. But these two codes just won't go away. the other thing I was figuring on doing is I did have a random this fire on cylinder 5 thought I would pull spark plug make sure it wasn't fouled out MMA check fuel pressure to make sure I don't have a leaky injector. Any help would be awesome thank you.

[@stephengoad3091]

Yes my 2009 Volkswagen Jetta 2.5 had this problem I had oil leaking all over the automatic transmission. I remove the four bolts on the metal cover use some high temperature gasket maker silicone. I've been driving it for a few thousand Miles now without an issue brake pedal also works fine.

[@donwilliams4602]

Do they ever make noise? I sometimes hear a noise at random interval that sounds like tapping on plastic coming from the vacuum pump area. Depressing the clutch has no affect on it so I don't think it's from the clutch or trans.

[@Accidic]

Assuming I didn't misunderstand... You said they shouldn't merely replace the rubber seal (due to being a sealed unit)? Before I stumbled across your video, I found it leaking thinking it was the rear main and realized it matched the error code for vac pump. With a manual it was stupid easy to change the gasket without even removing the pump (replaced with a slightly oversized one) and no more leak. I've still got a few small engine codes but am wondering now if changing the gasket is now contributing.

[@Accidic]

Sorry, my question is what would be the reason why for not replacing the gasket if it's the cause of the leak?

[@ShinyOwl]

Do you have video hot to change the whole 2.5 Jetta oil housing?

[@mattdebenham1924]

Hey. Is the vacuum pump linked with the camshaft in any way? Just had a top end engine rebuild on my crafter. The diagnosis was worn camshaft and failed vacuum pump. Looking through the history of the van, the vacuum pump was replaced only 4 years ago. I'm suspicious because the van isn't high mileage and it's been very well looked after. The tapping noise in the engine started days after having the cambelt and water pump changed.

[@JohnDoe-gm5qr]

Looking at that pump first as you mention from above could save someone a boatload of money considering how laborious a rear main seal change would be. It is nice that there is a way to change that pump without pulling the transmission which would be almost as bad as changing that rear main seal. I know that the rear main seal is very expensive to repair just because of the labor costs.

[@PaulWinnplus]

Great video! Not exactly sure wich part of the pump failed first on my 07 Rabbit. 3 months after replacing the seals (and no leaks) I was pulling into a parking spot and was greeted with a hard brake pedal and the strong smell of motor oil. After getting out and seeing the large puddle of oil I assumed a seal went bad (really bad) again. Turns out there was indeed a blown seal but that was just the result of the serious carnage I found inside. The 2 metal ears on either side of the black plastic plate had broke free from the shaft. Didn't hear it happen. This dented the front cover and blew the seal. Time for a delete kit.

[@CoolAirVw]

the nipple that pipes the vacuum over to the booster leaks as well. I have reselaed both the nipple and the cover successfully.

[@rayflores1748]

How did you seal the pipe vacuum to brake booster? Is there a grommet or oring that's supposed to make it fit on snug to the vacuum pump. My brake vac line is loose and leaking oil.

I bought a 09 TDI Sportwagon where the oil pump hex shaft rounded off and the oil pressure gave out. The car had been driven back home, lost power from the turbo and the brakes gave out. They had replaced the hex shaft but still no brakes or boost from the turbo. I took the vacuum pump apart and there was nothing but plastic powder left. I assume that it failed obviously because there was no oil in the vacuum pump.

[@tinohernandez7370]

Some auto trans cars the dealer will price removing the trans to do this. It is possible to change it by pulling the cover even on the auto car. Also it can be resealed, instead of replaced.

the only concern would be oil getting into the connections on the front of transmission.

[@womenssuite9169]

If you have a small oil leak which seems to be from the vacuumed pump. How long does it usually take to get bad enough that you have to repair the leak. I drive very little.

[@HumbleMechanic]

The rarely cause a big issue other than oil leaks. The oil can get in the connector for the transmission and cause a problem, but that is rare

[@joedavis804]

Would this cause leaking gasket cause hesitatio, rough idle when hitting gas to accelerate? I have an error code for Purge valve, Vacuum, and air loss. Replaced purge valve, and did a throttle body clean but still have an issue where Jetta seems to want to almost knock off when I get on the gas too hard. Was going to do the fuel filter next and some have told me a new gas cap as well...because I oddly also got a gas cap light about a month ago. Main symptom is car seems to be stuttering for air and almost cutting off, but no shifting issues or pedal pressure changes. I do have the oil leak as explained on here, but symptoms sound different. Ideas?

[@fadialsayar3611]

Thank you for the video, do I need to fix the leaking if I do not have any engine check light or any other problem?

[@HumbleMechanic]

The worst I’ve seen is oil leaking into transmission connectors and causing wire concerns

[@chingching664]

Leaking oil needs to be fixed because you don't want an oil mess on your driveway, you don't want to keep checking oil every few days to make sure your oil level is sufficient, and the cost of frequently replacing oil is wasting your money.

I used a blockoff plate from integrated engineering and ran the break booster to my intake manifold. Aftermarket for the win!

[@nothinglasts]

TaroFlava did the block off plate make a good seal? Check for any vacuum leaks. With my setup, I made sure the plate seated good with its seal and made sure the hose from the booster to the intake was tightened up good to not cause a leak. After finishing, I never notices a change in idle.

[@twentyone7738]

can you replace just the front seal. if your sure that's where it's leaking.

[@chingching664]

Yes, I know those who do only that. If it stops the oil leak, why not? (If the pump is creating a vacuum as intended.) Now, a purist would say this happens when you have about 130,000 miles or 10-12 years on the car, it's time to replace it all anyway, if your keeping it for years longer.

What sort of pressure do these vacuum pumps operate at, and if a vacuum pump was failing would it flag boost pressure fault codes?

[@HumbleMechanic]

no flag at all. It's only for brake assist. it's not monitored in any way

[@abdulh9687]

HumbleMechanic , on a TDI engine it uses the vacuum pump, plus solenoid to operate the turbo charger wastegate/actuator. If the vacuum pump was faulty would it flag a low boost code? Thanks for the reply mate appreciate your time. Also how many inches of mercury is a modern vacuum pump designed to create?

[@rontheis1678]

If the pump has failed, will replacing the seals fix the problem? Or is the pump irreparable at that point?

[@navidnima7051]

I know this is 3 years old, but I've had this problem lately, and the one thing thats holding me back from fixing it is that I dont know if I should replace the whole pump and its gaskets, or just get a gasket kit and replace the two gaskets. Is it common for the leak to be caused by the pump as a whole , or just faulty gaskets? Thanks!

[@HumbleMechanic]

Try the gaskets first and see. If that doesn’t do it, do the pump. You’re only out what $30 more bucks? Think about the fact that you can watch my diy on it and save $500

[@navidnima7051]

The pump is only $30 more than the gaskets? Where can I find a pump that cheap? I found a package with the 3 seals/gaskets on amazon for $40. But haven't found a pump for under $250. Maybe I'm not looking in the right place?

Hey there, informative video :) I just had a smog test which had ZERO information from this pump...it eventually passed the smog test but im curious why there would be no information and no CEL? perplexed

[@QPC_LLC]

Lol it's not computerized.

[@cstephenson3749]

Please do a video on Brake booster failure and replacement. Thanks,. I love your videos.

[@joelgerber1670]

Hello! Thanks a ton for you videos and help! I have a 2007 Jetta with the 2.5. throwing lean bank code as well as random misfires. I've replaced all the spark plugs and the coil packs. Pcv valve seems ok as I do not have any codes related and the oil cap comes off while running without the suction that's talked about. I know the vacuum pump is leaking oil but I'm wondering if that cold be the source of a vacuum leak causing the engine to run crappy? Sometimes, when it's warned up, it seems to run fine. Any thoughts or suggestions would be greatly appreciated. Thanks!

[@malcolmyoung7866]

Charles, great video as ever, I have a VW LT 35(Like a Mercedes Sprinter) here in the UK and wonder if this pump is fitted to my 5 cylinder 2.5 VW AGX diesel engine...is it fitted to all VW 2.5 5 cylinder motors? TIA.

[@curato28]

Did some.one try to use the rebuild gasket kits ? Is it works ?

[@fernandoboschelli2976]

does the breake booster line suppose to be loose. My booster line seems to be loose and i see oil around it

[@sezanshohel7462]
