How to Clean the Intake Valves on a Volkswagen/Audi TSI FSI 2.0T Direct Injection Engine

[@emikayee]

Bro, thanks so much for making this video, I know how much time and effort it takes to put something together like this and I appreciate you taking that time to do that and upload it here for anyone to watch. I didn’t feel very confident about doing this repair myself until I found this video, I just took the car apart this weekend and did the cleaning, got it all back together and now everything is running smooth again, no misfires, and CEL is gone! Just saved almost a grand by not having VW do it and also replaced my injectors while I was there which probably would have cost more coming from the dealer. I’m a rookie mechanic but I like to do as much as I can on the car myself so I really appreciate videos like these, thanks brother!

[@HowtoAutomotive]

Mike Smith Glad the video helped out. I wouldn’t say you’re a rookie to take on a job like this this is a big job. Thank you for watching!

[@zachhuffman9336]

yeah man this is definitely a level 4 of 4 job. I'm probably gonna do some inspecting and more tha likely gonna do this as well. I have a gen3 1.8 tsi but yes dude thanks for the video very much

[@recipioct]

This is not as hard as you think. It is minimally labor intensive and not frustrating. If you are prone to lower back pain like I am, that is the only thing you will have to endure. When I first watched this I almost decided not to do it. I decided to do it and had anxiety up until I started. It all went smoothly for me so don't be discouraged. Just be patient and gentle. It took me around 6 hours with some additional cleaning. When I have to do it again I'm sure it will take half the time.

[@mazpr2025]

BS, the intake bracket is a biAtxh to remove, the fuel smell, hands get scratched, and once the injectors are removed they have a plastic white seal in the tips and need to be replaced or else it will leak fuel and pressure from the chambers come out.

[@recipioct]

@@mazpr2025 My car has no intake bracket. I guess I was lucky. I replaced the seals as well because all the injectors came out. It will hurt your fingers. I had to do this 3 times because of a faulty intake manifold flapper. I learned a valuable lesson, don't trust a new part. It was easy, just time consuming. By the third time it only took me maximum 3 hours.

[@lsxfan5028]

​@@mazpr2025"Fuel smell, hands get scratched..." You have got to be kidding. 😂😂 And it's called an "O-ring".

[@mazpr2025]

@@lsxfan5028 It is not an o-ring you spoonfed fool. It is a cylindrical nylon tube style seal, a special VW injector tool kit is required. They are a one time use only, that is why it is a pain to deal with them. Not like other cars that it is just an o-ring. The nylon bushing (tube) is compromised once removed, not like an o-ring, NO, it is not the same thing. A typical o-ring would not hold the pressure of direct injection! Look who is talking, you have to be "gentle"... LOL 😂

[@danielk7417]

I had no idea what I was doing when I did this on my gti. Took me over 6-7 hours... now I got a mk6 golf R, time to do the same thing! I would recommend replacing seals while you’re at it

[@ClaudiuB]

do you have name or a part number for those seals?

[@francoisloriot2674]

Man you suck!! This guy did it in 26 minutes !! LOL just kidding. I'm sure it takes anyone not mechanic a few hours, look like reaching every single fastener is a pain.

[@bruno3682]

For anyone looking to do this, you can grab an adapter form 034 Motorsports and/or anyone that makes a Direct Injection Head Port Cleaning Tool. Basically allows you to have a vacuum hooked up and gives a small hole you can stick a media blaster into and blast the valves/carbon. I just did it today and it took 0 scrubbing, some slight scraping with a pick but no chemicals needed. Used 24 Grit walnut media @ 65 psi. For the rest of the job, its incredibly easy, just beware if you are higher mileage, some of the plastics will be brittle.

Doing one at work today. Finish tomorrow. Using media blaster with walnut shell abrasive. Use old radiator hose to connect vacuum cleaner to port and a stainless tube for a wand. stuff wand beside or through hose and go-to-town. Occasionally remove and inspect, blow out any stray media. I found with #1 on compression #2 & #4 would hold fluid so plan to clean three ports, turn engine 1/2 turn and clean #3 port. First one I've done. Will try to get injector seal kit as it's a lot of work to go back in.

Could the dirty intake valves be the reason my tsi is having random misfires on all cylinders? Especially when the engine is cold, cyl1 has a tone of mysfires, after 1 minute when the rpm lowers, it stabilises a bit, but they are still there, even on the other ones. It's a 1.4tsi, btw.

[@HowtoAutomotive]

GeorgeYT Cold random misfires is one of the symptoms for sure. And most likely the cause.

[@miahrx]

@GeorgeYT did you get it sorted bro? im having the same issue.

[@PlayerXification]

@@miahrx at cold starts used to have these really noticeable misfires that I could hear at the end of the exhaust for the first minute and that I could actually feel on the road when cruising on a hill for example. Took it to the mechanic for timing chain replacement and he probably did something to clean the intake valves because I don't hear these misfires when engine cold and not feel them anymore when going up a hill. They still show up on vcds, sometimes I still feel the engine misfiring when at a red light. So probably just a poor valve clean job or it was because of the old timing chain.

[@davidm.1934]

Yes it will have this problem bro. So will Audi A3, A4’s, S3’s, VW GTI, BMW 335i etc. Any Engine with direct injection port instead of multiple direct injection port will cause this problem. I own a 1.8T Jetta that needs this certain repair done. Lucky for me I found an excellent mechanic who is cheaper than VW dealership by 450$! I suggest you call a local mechanic near you and ask if any of them are familiar with walnut blasting direction injection engines. These engines are recommended to do this certain repair every 15-20k miles. I can’t remember the exact number but basically doing this constantly will improve the longevity of the VW 1.8T EA888 gen 3 engine. This and as well as common oil changes every 3k miles, transmission fluid changes, spark plugs, etc. Oh as well as changing your belts! Serpentine and timing belt, or chain can’t remember if these have a chain or belt. Nonetheless doing all this will certainly improve the changes of ever messing up on you! FCP Euro made an excellent detailed version that is insanely accurate as to what these engines are prone to fail & how to prevent them. Look them up & you’ll be proud.

I just had a question about the fuel injectors, the bottom seal near the injector spray area, you just slid the white seal on.

Is that something I need to worry about or does putting them on by hand actually work? Thank you again

[@LynxStarAuto]

Bolts are T30 but otherwise excellent video. Good job showing the intake bracket removal/set aside from under the vehicle. You need to compress the nylon seal with the special tool to get them to properly seal in the head. I used to shrug that step off, until I started getting comebacks 3-6 months later with fuel trim lean codes and leaky injector seals.

[@HowtoAutomotive]

Lynx Star Automotive i'm sure I missed spoken it was a T 30 I was using. I really wish I wouldn't have said that but otherwise I think it's a pretty good walk through.

[@LynxStarAuto]

How to Automotive it was a good video friend. But have you not had issues with premature seal failure from not compressing them with the proper tool? I used to just slide them on myself until I started getting comebacks with lean codes. Bought the tool, costs 80 bucks, and never had issues again.

To be honest a very well designed oil separator is as good as a catch can plus is cover but warranty. Guys who push catch cans are bias because they are trying to justify their purchase. Furthermore if you have a ccza or ccza or most ea88 series engines, you will need an africa plate and a high quality oil separator in the catch can with baffles. This is by no means cheap. My suggestion for dirty valves on the tsi would be to recommend a water meth injection kit 😇 same price as a nice catch can but also performance increases for the mod lyfe 👏

Keys are using a quality low NOACK Volkswagen approved synthetic oil, using top tier fuel and driving the car. Short trips where the cars don't get to full operating temp, low fuel quality and the wrong oil will get you carbon buildup quickly. Also change the plugs about every 40k miles.

I have done the rear main seal Vacuum Leak... Valve cleaning.... Clock Spring (Very unusual style clock spring) and trunk wiring... Now I have the CC coming out of the shop today or tomorrow with a new Dual Clutch in the DSG... (Not Cheap) What else should I check for prevention... I am not complaining, just trying to prevent future issues. Thanks again Brian for your great post!

Did the recall for FPCM (fuel pump control module) and airbag about 3 weeks ago. Faulty FPCM symptoms: loss of motor power while driving (EPC light turns on), engine shuts off, battery light on and car won't start (FPCM drains battery when it shouldn't be). Before I knew about the FPCM and independent shop not being able to pick up it's corresponding code since at times it would pop up and when rescanned it would go away, I kept on getting misfires with the symptoms from above and ended up changing injectors, turbo valve, and throttle body. The faulty FPCM symptoms have gone away for now but still getting misfires. Im not sure if those other repairs were in the end necessary. So definitely check that out. My car vibrates when I start it in the morning and over time as it gets warmer it starts to smooth out. Took it to the dealer and said the cause was carbon buildup in the intake manifold and recommends this exact service. I declined because I wanted to find out more on the procedure itself to see If I would be able to do it, but it's a little advanced for me so ima take it back later on. The CC is a nice car design wise and I love it but with this experience I definitely won't be buying a VW anytime soon. Got my CC used with 129K miles for 5900. But has really costed me about 12000 :(

[@Areviloche]

At what point must the injection valves be replaced?

[@unprofessionalmechanic8466]

What is the mileage of this vehichle? Any way to snake camera in for inspection before "removing everything"? I have 2013 Audi TT with 50k on it, so trying to understand at which point do I need to start worrying about carbon build up. Any specific reason you did not go with wallnut shell blasting?

[@EmbraceMaking]

Did you change your oil afterwards? Any chance of that chemical leaking past your valves and into the combustion chamber or past it and mix with any of your oil?

[@HowtoAutomotive]

Embrace Racing there's always a chance the Chemical and carbon will get into the combustion chamber so it's a good idea to change the oil. You are already taking the oil filter off doing the job. I did change the oil. Thank you for inquiring!

[@paveljelinek772]

mannol EGR cleaner wil do the trick BUT it has to be all the can (500ml) BEFORE every oil change and max change interval 10k kms, otherwise the intake will clog up in time

[@diegopad14]

Hi, does anyone know where the secondary air pump(bank 1) goes?

[@marwankalian4995]

If you have it in your car it will be under the passenger side headlight inside the bumper

[@raffitchakmakjian]

Hello good sir, I hope you can answer some questions I have, as I'm taking a road trip in a couple of weeks and would like to tackle this repair correctly. I'm no stranger to DIY repairs, but this is my first crack at a fancy German car. I have a fuel leak from beneath my intake manifold. I haven't inspected it yet, but I have no codes. I'm hoping I can spot the source of the leak when I pull the intake filter box off tonight and I'm hoping it's just the intake manifold gasket or the injector seal that's leaking. That said, if it is a gasket leak, should I be replacing the whole manifold given the mileage of the car or just the gasket? Car has 109k miles on it and does not throw any codes. Thoughts?

[@HowtoAutomotive]

Raffi Tchakmakjian Hello. As far as replacing the manifold I would look into seeing if you have the current updated intake on on the car. May have to check with the dealer on that. If it’s the old version I would upgrade it and if it’s the new version I think you’ll be OK. Most likely the leak you have is an O ring from the injector. Good luck with the repair and thank you for watching!

[@raffitchakmakjian]

@@HowtoAutomotive hello again, so I removed the intake filter box today to get some room to look around, and I ran the car briefly to get the fuel to leak. The leak looks like its coming from the nut/connector on the hard metal fuel line you can see in your video at @7:09 the end that's on the bottom there where you say you just loosen it a bit to give it some wiggle. Is this a typical leak spot and what are your thoughts on fixing the leak there? A new line or just tighten it down some? Would you know if there's a gasket in that connector? I won't flood you with additional comments, I'm posting on the forums as well but they move kind of slow :)

[@HowtoAutomotive]

Raffi Tchakmakjian there’s no gasket on that line is just a compression fitting so tightening it down and maybe repositioning it should stop the leak.

[@raffitchakmakjian]

@@HowtoAutomotive that did the trick! No more leak! Thanks again :D

[@raherre]

What other chemicals are safe to use to loosen all the carbon? Is a regular carburetor cleaner fine? Also, is it OK to simply dry the valves with a rag once I'm done?

[@HowtoAutomotive]

Raul Herrera carb spry works well. As far as drying them I don't see why a rag would hurt anything.

[@raherre]

How to Automotive thanks! My new injectors came in today and I'll be doing this later today.

[@MMSstation93]

hello dear.. i just had intake valves for my mk6 gti stage 2 apr cleaned and done.. bt still have littlebit of cold start misfire.. mch better then before and what u have to say abt performance after cleaning?

[@reenahgolden1674]

how long a job is this in real time?

[@cheesetoucher5941]

1 hour if you know what you're doing...

[@rulogalletaz]

@@cheesetoucher5941 two days if your not know what are you doing I Think

[@asuhadude4817]

Did you have to take the engine oil out or can you do it without takeing it out

[@dividad1]

Did you watch the video? Or even briefly skim through it?

[@golfmaniac007]

there is an extra step on the injector seal tip side....it needs a special tool to tighten or reshrink the seal once its in that groove gap.

[@vaseabmwe39]

A ziptie is the name of that tool 👌🏿

[@vincentambrose7831]

I thought I would watch a quick video before trying it myself. Yep not going to happen.

[@NearTheLimits]

does carbon build up reduce power over time due to lower compression? I drive a VW TSI. Thanks.

[@HowtoAutomotive]

Albert Zion he shouldn't affect the compression at all. I can't make it reduced power because it disturbs airflow over the valves. Unless the carbon is so bad that it's holding the valves open.

[@NearTheLimits]

thanks for the reply.

[@BenState]

yes, carbon can make valves not seal and burnout

[@bruno3682]

Well, like many, I'll be doing this soon. Wifes tiguan is hesitating/surging and not consistently. No codes in system.

[@beesteezy3626]

My intake manifold is stuck on there solid lol. I took out everything but wont even budge when wiggling it.....idk what to do and dont wanna break anything

[@brianenos6150]

Thank you so much for posting this! This is the 3rd video I've watched to tackle this job myself, and yours is by far the most detailed. Dumb question though, when you rotate the crank, should it be notated where it was originally?

[@kbent88]

Nope doesn't matter.

[@lowpez55]

hello how to auto, if one of the valves is partially open how do i turn the engine to close the cylinder, or are they all closed ?

[@HowtoAutomotive]

frank lopez on the right side of the engine from underneath you have to take off the splash shield and use a socket extension and a ratchet on the crank pulley and rotate the engine clockwise . Do not rotated counterclockwise. As you're rotating the crank you will watch the valves and watch them close. If you spray a little bit of carbs spray into the valves and it drains away the valves are open and if it puddles up then the valves are closed.

[@lowpez55]

Clockwise would be towards the front of the car. Would you mean on the left where the serpentine belt is?

[@lowpez55]

I would like to thank you for taking the time to help me

[@HowtoAutomotive]

frank lopez yes to both questions.

[@gokhanymz9428]

Is there any place where i can order all the seals you have?

[@HowtoAutomotive]

Gokhan Ymz there are affiliate links for the parts in the description of this video.

[@dougmoreno4711]

Could carbon buildup cause random misfire?

[@HowtoAutomotive]

doug moreno yes it can cause random misfires. Most common symptom is on cold start up misfire for a few minutes then clear up.

[@kellymurphystl]

Yes - It blocks intake air.

[@x-man4702]

Good video, thanks for posting! Did you try gasoline to clean the ports? Is Berrimen's B12 stronger than petrol?

[@HowtoAutomotive]

Xavier Lemos I like the b12 but the best way is to Walnut blasted. Her is a link for doing it kzbin.info/www/bejne/foCxpY1ojKaims0

[@SloanZurnToto]

Amazing video. Very detailed. Any way to avoid the carbon buildup, so you can avoid this??? Would spirited driving work, or a long highway drive?

[@HowtoAutomotive]

Doug Maverick thank you for writing to me. The best way to prevent that carbon buildup is to use high-quality oil and fuel. They do make a catch can system that replaces the PCV that will greatly improve the carbon buildup.

[@SloanZurnToto]

Can you recommend a particular catch can, would installing one void your warranty?

[@HowtoAutomotive]

Her is a link for a can they I would use. shopdap.com/store/racinline-catch-can-mk7-gti.html

[@jakesmith2984]

Doug Maverick As a 1.8 owner.High quality fuel and oil dont do anything.Nor "spirited"driving.Catch can is the only thing .Its the emission crap egr and all that causing this

[@MoXyiD]

Is there any way you can list the tools, and a rough time table of how long it should take if I've never tackled a job like this?

[@HowtoAutomotive]

Alex Goldberg this job took about 3 hours. You will need T30 torx socket, 10mm triple square socket, injector oring install kit. Don't have part # and standard hand tools. Hope this helps. Thank you for watching!

[@bigimskiweisenheimer8325]

Thank you. You answered specifically what I Needed to do this with limited trips to the parts store.

[@Jobey_99]

This is probably to late to ask, I'm not having any issues yet but after a faulty PCV and 60k miles I wanted to do this, Would anyone recommend any spray intake cleaners in the UK to try and keep on top of the deposits
