Audi 3.2L fsi motor intake manifold carbon build up and thermostat replacement DIY by Edge Motors 

59 people are haters and don't appreciate good knowledge when someone takes the time to offer free lessons. Good info and good teacher

Just changed the thermostat on my wife’s 2008 A6 3.2, couldn’t have done it without your video. Thank you!

This is one awesome video lots of good advice and very informative. The mechanic working on the car is top of the line

Your video is the best. With that head camera, everything you touched and removed shows clearly as you work. There's not another video like yours. Your instructions are very clear.👍🏾👍🏾👍🏾👍🏼👍🏼👍🏼👍🏼

Your vid really put my mind at ease. Thank you for the lesson. This seems a very simple job now. Subbed. The shop was gonna charge me over 550 bucks for exactly the same job, gonna just do it myself now

Thanks for the video. Did this over last couple evenings. I wish someone had a walnut blaster adapter for this engine. It's messy and difficult to get all the brass bristles out. But the engine started back up, so that's a plus. Thanks again.

@edgemotors, thank you, thank you, thank you for making this great instructional video! I did this and it work great. I did have hydro lock though. I recommend taking out the plugs and cranking it regardless. I was 100% certain nothing got in the cylinders but still had hydro lock. Thank you again!

I did a similar job on my BMW 335i. I used a media blaster and ground walnut shell to blast the carbon gunk off. It made the surfaces bright and clean in very little time and was gentle on the metal.

Dealer wanted 2.5k for doing this. I finished this up in a day following this and another vid. Many thanks.

Congratulations for the whole video, you are a excelente teacher. This kind of teachers we the mechanics need in the whole world. Thank you again for the good instruction

Great video! Thank you for taking the time to document this repair.

+Edgemotors, Good video, done the way most DIYers will do it. Like myself in a couple weeks on my own 2006 A6. If I may offer a suggestion on screws in plastic, or anything not machine threaded. - Turn the screw backwards before you start it. You'll feel when you get back into the old thread groove, and use that. It will make the threads stay much stronger for much longer than just cutting new threads every time. Thanks for the help!

About to change the thermostat on my 3.2L A5, thanks for this!

I just want to say thank you I follow the process and did it myself first time it saved me a lot of money😊👍

Awesome video and details for this repair. Thanks for taking the time to document and post!!!

I appreciate this video a lot. I would have been lost on how to get to my high pressure fuel pump. Keep up the the great videos, it has been so helpful for us.

Wow.....great video! Thanks for being so thorough.....awesome! I hope that I never have to do this to my A3 2.3l but I'll be watching this video again if I do!

Scraped off the the large stuff then blasted with walnut shells to finish. Worked great!

Great instructions straight to the point and emphasis when n where needes like the tabs. Idk how many people break those.

Thank you!! Great video. Not enough Audi stuff out there. I just acquired a 2005 A6 3.2L car. Big learning curve. :)

Bardzo przydatny filmik.Moj 3.2 fsi z 2005 przebieg 174000 juz ma czyste zawory☺. Samochod zdecydowanie lepiej przyspiesza.Brawo dla autora filmu

Thank you for the video. Very well done. Hope you could make more like sealing the engine with gaskets or a dressing oil leaks on this engine.

very good job.. and nicely done...keep making these videos you help us a lot...much appreciated .

Great videos. I will probably have to do this on my A6 soon.

Excelent instruccional video!! I need to clean my intakes on my audi a6, i can follow your explanations cause your great mechanic.. thanks a million.

Used your video to change me thermostat! Thank you so much. Saved me like $600!

@Edge Motors, massive thanks for this video. Also, if anyone is interested the VW tool used is Schley (SCH96280) Power Steering and Water Pump Remover / Installer. It can be easily found (eBay) just search for the part number.

I soda blast the crap out of those ports bossman. I bought the media blaster from Harbor Freight (less than 100.00) and I do all runners in about 10 minutes. I use walnut shells, and have a shop vac running to absorb the contents. Leftovers I used compressed air and blowout the engine bay. You should look into it. Cut your labor times. We work on the same type of vehicles.

Awesome video. Very nice job. Thank you. I really appreciate it, and will be doing the job this weekend.

I like the way you get things done 👍

I like your job bro. You shows alot of good examples

Very good video, makes the job much easier.

Very detailed and helpful, thank you !

Great video! Thank you very much!

Very helpful information!!! Thank you sir!!!!

Thanks for the Video, helps a lot. You are the best

great vid man keep em coming!

It't good to know that there is other people like me that are pasionate about what they do and they care of the quality of workmanship and they like what they do and does show for you.

Fantastic video! Thanks!

hi. ive just recently got myself an audi rs4 -06, im about to clean the intake ports from carbon buildup just like you do it in this video, with that said im wondering what type of cleaning product you use to fill up the ports with? looks like it does the job really well. thank you for an awesome channel!

Thank you so much for this video! Helped me to feel much more comfortable in doing! -hoping you might have some ideas or feedback. Everything is back together, no leaks, but I also have no HEAT! stuck thermostat? -any ideas why? Also, I broke the Secondary Air Intake pipe :-( -I have back together, but likely temporary, any ideas how to get that dang thing off?? Thanks again, amazing video!

Great video,very helpful

Hey just did this on my 2.0FSI, after watching your TSI video. A little tip to bump start the motor without the injectors flying out, is to remove the spark plugs so there is not pressure in the cylinder. Stuff the fuel lines into an empty bottle so you don't have fuel everywhere... Also, for those who dont have a "fluid evac pump" i just dried up the cleaning solution with shop towels, and used compressed air to blow out all the rest of the shit so no little bits of wire brush or whatever fall back into the cylinders. UNBELIEVABLE how much shit was in my intake... Thanks again for your videos man, you really help us out.

So much details help to be confident i could do the job. Just wondering do you need to open the vale as before cleans the intake ?

thank you for helpful presentation

Thanks! Great video

great video. Someone mentioned the 3.0t is very different disassembly? that would be great if you guys made a video on that.

Thanks for making this video. Did you have to do anything special to purge the air out of the fuel lines? Or is it not an issue with the high fuel rail pressure?

Very good vid. Dont stop

Gracias, esto me ayudó mucho Yo lo hice por que me fallaba el sensor del gasket manifold intek Y resolví el problema

very helpfull video. how often intake valves need this cleaning???

great video. i plan on doing this myself real soon. would it be a good idea to also clean throttlebody and intake runners?

I can't belive this is way easier then the 1.8ts and 2.0ts intakes. Holy crap sooooo eassyyy

I hope you get at least a weeks pay for that. Thats a big job. Nice work.

Молодец мужик, грамотно все сделал. Well done man, did everything perfectly. This is 3,2 AUK?

Fantastic video! What did you use to suck to cleaner out of intakes? I see a hose but what is it attached to? Also how many miles until you see carbon buildup like you show?

I believe a really good polishing job on intake ports and catch can would help with this.

Great video and very informative! Helped me immensely, I would have missed the flapper alignment had not been for this video. When can you do a cylinder head replacement for this engine? Doesn’t exist on RU-vid

good job. i was wondering if you can do a fuel pump and the hpfp (high press fuel pump) on those engines. thanks

Thank you for your video 👍👍....

Hi bro Greg from Australia can I get some advice pls? you've helped me sort with my old 1.8t a4 .I trust you above most others. Now Ive got a 2006 3.2 b7 choking on oil (as they do) .. I will try clean the carbon out one day but meanwhile I'm about to install a oil catch can. Thought it'd be easy.. but after watching some vids I'm now totally confused as to how to route the piping. I had a mad idea of running a oil catch can on either side of the motor.. out of the top (next to the oil cap filler) into the can, and back out into that same pipe that was connected (next to the oil cap) Then figured Id repeat all that on the other side/bank of the motor (but another dude was talking about the left bank being the clean air intake and right bank being the dirty side etc ...and had a much more complicated system going on..totally lost me) what am I missing here ?? wish you were in Oz man! happy to fling some coin if you can sort me out cheers Greg

Thank you, edgemotors! Would this carbon build up occur on the 3.0 TFSI engine? New generation?

Great video, really helpful. What is the Torque specs on the thermostat housing and intake manifold ? :)

one of the better views inside the 3.2, was watching trying to find the coolant temp sensor :) hahah

Edgemotors thank you for taking the time to make and post this video. i do have a question my 2008 a6 3.2 when you removed the lower runner VCDS gave me this cold "Intake Manifold tuning valve (bank 1) P2070 stuck open. now when i manually press the actuator it moves, when i try to test it through VCDS nothing happens; with your experience what could be the issue?

do you have video about replacement of crankcase ventilation valve which cause oil leak in the valley of the v shape audi A6 quatro 3.2

great video guys

Hi. I have watched your channel for a while now. Some time back you did a pretty detailed video on taking apart and cleaning the intake ports on a 4.2L with manifold runner flaps. I cannot find that video anymore. Have you dropped it? And can you send me a link to it? Thanks for all your great video's! They are very informative and very easy to follow. Best, Jay

Liked this work alot although I don't have a car like this one. But I think the intake looks good and it can survive more without cleaning. On the other hand, It is good to do it regularly.

Great video! One question, Why, when replacing the t-stat involves that much work, would you not replace that short hose also? Couldn't be a $10 OEM part even at the OEM ripoff price. I know I would have just for cheap insurance and peace of mind. You do good work. Is the carbon buildup design flaw of DI engines a fatal one for all these new style engines? You can pay for a LOT of extra fuel for what the cleanup costs are every 60,000 miles or so. Thanks

Do you need to remove the fuel lines and lower intake manifold in order to change just the thermostat? BTW great work and vid.

where did you purchase the o-rings for the injector? I can't seem to find them except in a kit.

Do you have a video on how to replace the coolant pipe on 2006 Audi A4 3.0 convertible on the fire wall

Great video…

Should I take the time to replace the crank case vent gasket? The piece in the middle area while we are here? I have pooling of oil at the right of my thermostat, is that just from the intake gasket, or is something else leaking?

Very good job!!!

great video thanks.

good job ....why did u replace the thermostat? what are the symptoms that pointed that the thermostat is defective....is it just the leak from the gasket? I have the same problem a leak from the gasket and the white smoke (unburned fuel) and I am suspecting the thermostat which definitely needed to be replaced.... I will follow ur video

great video.

Hello Sir... Thank you for the great videos, I have an oil leak from the engine on the right side just below the radiator bottle ,the oil leak is so much that i have to fill lile 250ml every 2 weeks. the engine is good and no problems or sounds . the engine was never opened, it has 160,000 km. thanks.

Kerosene is also an excellent solvent and cleaner for de-carbonizing intake valves.

great Job bro

Would it help if I replaced the short coolant hose on the thermostat with a silicone one one? I think the silicone are more flexible? If so what size is this hose?

what do you use to vaccum the chemical out of the valves?

Great video...Thx.

Great vid

is it ok if I had rotated clockwise with the special wrench in order to turn the valves?

if I wanted to just replace the thermostat, could I just skip removing the fuel rails and etc? Also, while replacing the thermostat, what else would you recommend that needs to be replaced/cleaned?

Awesome...thank you

Nice visit indeed, I would’ve also cleaned the intake flaps

I have the same engine and I have a question. I do have a lot of oil on the top of the engine and It falls on the belts. The oil seems to come from the freeze plug on the top 'cause the two holes are always full of oil or from the oil filter housing gasket. I replaced both and it's still leaking a lot. I have no idea when to look. This is really strange.

do you have a vid on the a8 v8 intake manifold flap rods removal.

To remove the thermostat hose I had to get the front crossover water pipe out of the way, to get that forward enough I had to undo the top radiator hose and both flanges to the heads, as well as remove the ribbed belt to get it out of the way. This would have saved some time, though not sure it would have worked with the new replacement hose that was not as soft as the bulging old one.

Great video. What is the water pully pulley tool part number?
