Today we are diving into the 2.5L vacuum pump leaking oil. Last week we looked at how a 2.0T rear main seal fails. The funny thing is, this vacuum pump leaking is often mistake for a leaking rear main seal.

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 UA-cam 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.
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...
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!
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.
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
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.
dtownyogi You are welcome. I love when customers have extended warranties. It makes every one happy :)
Im slowly getting to know my way around mk5 and your videos hit the nail on the head thanks
A big thanks for your time and efforts in doing this video. Answered all the questions I had with the oil leak on my 06 Jetta.
Great video, thank you! Can you do a video on replacing the combi valve and secondary air pump?
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!
Awesome
More 2.5 videos please
anything specific?
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
Cool. I'll see what I can do.
Yeah 2008 VW jetta 2.5 leak detection pump!
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
Thank humble Mechanic, and your sponsors helps a lot.
You are an excellent teacher! You could be a great auto shop teacher at a high school. Thanks so much for posting these wonderful videos.
+carolyn soderstrom thank you so much for the kind words. I really appreciate it
Subscribed. You explained my situation with it being rear main seal vs vacuum pump. Have drops on bottom of vacuum pump so will start there first. Thanks!
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.
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.
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.
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.
Yeah the manual labor is almost nothing. Lol
@@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!
@@DerKooze do you have an Automatic Transmission?
Na-Na & Romie no. My OP states I have a manual transmission
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.....
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.
Very informative video...thanks a lot! Not able to repair myself, dealership just quoted me $1,275 to repair...does this sound reasonable and should I look else were?
not upset that you are 'fiddling' you know your business its respectful to us because you know what you are talking about thank you.
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.
hey, you are the best in vw's. i have a 2006 vw jetta 2.5 L 5 cylinder manual .can you show us why pressing the clutch the gear shifter does go in gear.when turn car off ,the shifter would find gear. then start car and it would drive.but try getting in to another gear depress clutch it would'nt go.
great video, after car sat for 2 weeks , brake pedal was going to the floor, looked and now it's leaking, so im assuming i have to change vacum pump. no leaks detected anywhere else in brake system.
Please do a video on Brake booster failure and replacement. Thanks,. I love your videos.
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!
Need to team up with Deutsche Auto for a DIY on this, at least for the manuals.
That's a great idea. :)
Can you do a video on replacing the secondary air pump and how to diagnose a failing one. I'm almost certain mine has failed in my 2013 golf automatic
Very helpful! I am not a car expert...your explanation made sense and I now understand why my 2009 2.5 Jetta had this leak :)
Awesome. Glad to help!
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.
Awesome videos man! Do you know what part number it Is for the transmission shift selector seal on the 2.5? Do you have a video on changing it?
Superb! I have my2006 1.9Tdi Vw touran în limp, found ouț tandem pump has a veryy loose hose Joint (the one pointing to the rear.
I want to stick it w epoxy, hope ți avoid grtting any în the pump,as it s really sealed
Do you have a video on replacing the pressure hose for the power steering on a 2.5L 2012 beetle?
Thank very much for the video! Very informative....educational even. This helped my gauge if it was within my skill to do it myself on my 2011 Golf (and I don't think it is if the transmission has to come out! Hahaha) You're great...I'll refer your videos and site to friends!
Thanks for the video! I have a 2011 Golf 2.5l and the dealership said my vacuum pump is just starting to leak.
I previously messed with the brakes with my obdeleven (just from the apps nothing further) and I heard you said something about the brakes in the video. Could that be the cause? Specially that you mentioned not seeing as much Golfs leaking as other models. Your response would help a lot and I can send as much more details as needed! Thank youu.
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.
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.
I have this issue massive oil leak.i already have a new pump and im getting ready to change it after seeing your DIY vid. Just one question? What kind of oil is it that leaks out of it?
I have a 2013 Passat SE and the small plate inside the vacuum pump failed and it did exactly what you said the brake was hard
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.
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?
+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
Hi there! Nice video man, I think Im about to have that problem, since my Jetta 2.5 was leaking oil from that part, this started after the service done, even the oil light flashed at times... I tried a fix and seems it worked.. Since it's a vacum Pump I removed the oil cap with the engine running for about 5 minutes, then turned it off. After that no more leaking and the oil light hasn't flash... Hope this helps and if it does not work now I know how to fix this, Thanks bud!
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.
Did the leak stop?
I had just this repair now a month later I need to get my struts and shocks replace now I don't know anything about cars so it will be helpful if you will let me know if maybe these two things are connected to each other ?
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!
Have a 2010 Beetle & Apologies if this question was already addressed, but did symptoms include rough idle and engine sputtering upon acceleration in lower rpms?
Great video and how things work.Been having issues with my braking wheres after 3 presses of the brakes they went solid , so the mechanic i took it to assured me it was the brake booster which he replaced but this made things worse as now i have a really solid brake and i really have to put weight on it to work , the car does stop but with effort ,he said it most likely the Vacuum pump as well so ended up paying double labour for him to put my old brake servo back in and now im looking for another garage but hoping if i spend money again it is the vacuum pump which will solve my issues , do you think i should replace the brake servo and vacuum pump at same time as well? , car only has 165.000 which is not allot for a diesel .
ok question for you. I have a 06 jetta with the 2.5 My brakes will randomly hang up on me and not release all the way. it varies on what break but most of the time its the front right. I need help seeing its to the point my pads only last about 2 months or so.
Hello, and thanks for the videos.
I have a 2013 Jetta 2.5 and I bought the car with 75k miles, the car is great but recently I have been having problems with the brakes, it gets stiff when you pump the brakes. In the video you mention that the purpose of the pump is to create vacuum for the brakes only. Is is safe to say that I should check the red seal of the pump and reseal it if necessary..!?
Thanks in advance..!!!
my wifes 2009 jetta with 2.5 is leaking from this pump, dealer keeps reminded her that its leaking oil and they will replace for 1,150 dollars, they are crazy, should be a recall and not fall on owners hands if problem is very common, dealer only had the back medal gasket, looking for the front gasket? was going to try to use black rtv on the front cover and hope it stops leak. keep up the great videos....travis
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.
I have a 2.5 and there is a vacuum leak. If oil cap and/ or dip stick is removed the leak is noticeable i have replaced the valve cover and problem has reduced but not fixed due to leak still present. What else can i test or known problems.
Hi i took my car to do an oil change at the dealership they mentioned the vacuum pump is leaking oil does this need to get fixed right away or its something u could wait for later on.
Just replaced mine but the 2 gasket and o-ring... my brakes hot super hard. Prior they were soft and went to the floor slowly.... could it be that inner part that rotates?
i have a jetta 2.5 and it makes a winning noise it goes on an off in particular side of the engine could it be this pump the problem?
Vacuum pump failed on my mkv gti tsi the other day after an emergency braking... I almost crashed on the highway Bc the brake was stiff as a brick.. Smh. Picked my part up yesterday, and will be replacing today
bigspank55 How did the replacement go?
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.
Hello Charles,
Great videos! Here’s my question. I went to get an oil change at local VW dealer they told me i had an oil leak and it was the head gasket. Don’t know why but i was skeptical. I went a week later to a local mechanic (used to work for VW) and he did checkup and wasn’t sure about the leak because of all the gunk and oil except he said that he deducted that it could be many thing but not head gasket. He went on and told me that it could be part (boot?) holding in place the oil filter. Could it also be the vacuum pump? As by watching your videos it seems it’s a common failure on mt car (oops forgot to mention i own a VW Rabbit 2007 manual transmission 2.5l).
I don’t have any break failure.
Thanks for the help!

I had my metal gasket rust and cause a leak on my 2.5 Golf. Some of the paint was chipped off and stuck to the pump assembly itself and there was heavy dirt buildup.
Is there a block off plate for this part? And if there is, how would that effect the braking or feel?
what about the mk4's jetta's with automatic transmissions. They very often get the P1479 code for circuit open to brake vacuum pump. How do these fail and why?
Hi humblemechanic
I replace all gaskets on the vacuum pump this past weekend but today I got a engine light on with Code :P0411. Could I have reinstalled it incorrectly or is this a whole other issue? I have a 2008 VW rabbit
What happens if the pump leaks oil? The pump just fails to make vacuum? Im having braking issues with a bmw x5. The first brake push works but after letting go and pushing again the braking assistance doesnt work. Or if i press the pedal all the way and maintain it pressed, the pedal slowly comes up again. Is that a vacuum pump problem or is the brake booster? I need help
does the breake booster line suppose to be loose. My booster line seems to be loose and i see oil around it
I changed the gaskets on my vacuum pump and after doing so I had several lights turn on my vehicle. ABS, Brake, steering wheel light and check engine. Speedometer not working and gas gauge fluctuates. The abs module is now not communicating with the computer. Could my whole pump be bad and be interfering with my computer? Or do I know need an abs module? Didn't have an issue with the computer and lights until the vacuum pump was taken out and gaskets we're replaced. 2008 Rabbit 2.5L
I have oil everywhere and I’m sure it’s this part leaking. Would I have to replace the whole part or just the seals? 2007 VW Rabbit MKV
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.
***** the manual is SUPER easy.. You will spend more time cleaning than you will replacing.
A couple of threads here generally mentioned moving the transmission to get to this vac, is that true?
that is unnecessary
Hi, I have a question
Took my 2012 Passat 2.5 in to have it checked at the VW Service for knocking noise. On the report they wrote that the vacuum pump is leaking large amounts of oil and that knocking noise coming from connecting rod 2 or 3. They told me verbally that the rods are worn but they dont think it was caused by vacuump leaking oil but maybe a bad oil pump. Their recommendation was to replace engine ($9k plus), or take it to another mechanic to rebuild. What are your thoughts/recommendations? Thanks
In 2.0 engine could it cause turbo underboost if the vacuum is leaking? Thank you
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.
Nice
automatic 2.5 on a jetta. My car has all the gear lights indicated, but drives just fine. I've gotten use to it, but I'd love to have my triptonic back. I don't believe it's the mechatronic unit, I think it might be the switch for it but not sure.
sorry in advance if there's already a video on this.
Rossi Motilal The only way to know 100% for sure is to have the faults checked. The TCM (transmission computer) will store faults and tell you the area that it sees the issue.
Have a 2013 buick regal turbo and my pierburg vacuum pump part# 7.03097.02.0 07 is leaking oil and I have a engine light with p0299 underboost would the leaking cause the turbo not to build boost?
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.
Can you please answer this
I parked my Jetta 2.5L then after 3 month the alternator don't working can you help me with this.
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.
My brake pedal do not return , i change the master cilinder and still not return, i am about to change the buster but i just see your video about the pump and i wondering if have to do something with my issue.
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
Lol it's not computerized.
I replaced my break booster and master cylinder, got new break , flush or whatever it’s call the break fluid it was running good for 5 months and now a have a really hard break petal and the breaks are sticking , could the vacuum pump be the problem ?
We have a 93 Eurovan that has a 1.9 TDI engine installed. trying to identify which 1.9 it is....1Z or AHU. It does have a Garrett turbo on it and I read that all 1Z engines have a Garret turbo...is this true?
If the pump has failed, will replacing the seals fix the problem? Or is the pump irreparable at that point?
I have a VW T5 TDI 174hp. I am finding my oil level rising. no coolant loss. very thin oil.
No oil leak below tandem pump.
Can diesel leak into the oil from a broken tandem pump seal on the shaft.
Do you have video hot to change the whole 2.5 Jetta oil housing?
Hello! Where can I get the original spare part from the vacuum pump? In Mexico they sell the complete pump.
great video but you left out the booster check vale oil ring .i need to remove the check vale
Hey, you say there is a new revision of this part with a different cover plate. Is that the 07K145100H or the 07K145100C?
Dang. I was hoping this was going to be a DIY repair video. I'm working on a Rabbit for my in-laws. I think I'm gonna go try to reseal that gasket since it's a total budget job. Have to do the valve body as well.
Where is a good place to get a repair manual for a 2006 Jetta 2.5 stick shift?
is this the same for the 2008 Transporter t5 2.5l engine?
@humblemechanic My wife’s 08 2.5 beetle has a loose brake pedal. In the morning it the pedal floors to activate then gradually activates higher. Changed the booster already but it’s still doing it. Could this be a bad vacuum pump too?
The o- ring on the plastic port that connects to the booster hose was leaking on mine
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.
Muy buen video aunque nose el idioma pero con solo verlo quede satisfecho gracias mil
Hey Broski I had my vacuum pump on a Chevy Malibu 2013 2.5 eco-tech it disintegrated inside of the pump also has damaged the camshaft please help I really could use your advice. David by the way
Curious, what are the downsides to deleting this? I did the delete a long time ago and never had issues.
My VW Jetta SE says it's a 2008 on the registration. But the VIN says it's an 09. Is the vacuum pump the same for either year just in case?
Hi humbleMechanic. Thank you for the video. I just came out of the VW dealership and they told me I have a vacuum pump leak and its $1300. I have a 2009 Jetta automatic transmission which I have always taken to dealership for any fixes. However, given the fact that this is more expensive, I was wondering if this is a job that a regular mechanic ( not a VW shop) can actually do and hopefully charge a little less. I appreciate your input, even though I am no car expert at all, when I have an issue with it I like to research about it to see how it all works. Your videos have always been helpful!
+rossytus this is a super easy job. Try and find a VW specialty shop to bring it to. Or DIY. ua-cam.com/video/TvMWRCR7y_E/v-deo.html
Thank you so much. I can't do it on my own, my nails will break and I don't own one single car tool, I don't trust myself for this at all lol. But will find a mechanic/someone trustworthy who can do this and get the parts from the site you recommended. Even the parts are cheaper there than the price I got from the dealership! Could you be so kind to tell me what are the consequences of not doing this soon? I am not sure how long it has been leaking since I can't see it. Again, thanks a bunch!
Is the vacum pump connected with my gas tank in any way? Just came back from dealer and they told me that my vacum pump need to be replaced. I have asked about the gas tank case also I have a problem with my tank as pressure is not being released from the tank. I have Jetta 1.4 Hybrid.
Great video and very helpful and very pratical.Good work !!
thank you. :)
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?
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?
My 2006 Jetta jerks when i accelerate do u know why that might he happening? And has a strong gas smell and engine stutters when i get a cold startup any ideas?
I used a blockoff plate from integrated engineering and ran the break booster to my intake manifold. Aftermarket for the win!
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.
Does anyone know if the vac pumps on the 2.4l & 2.5l interchangeable?
