[@liorb3494]

Thank you! you helped me a lot. did a TB cleaning on VW POLO 2006 MK4, this weekend exactly as you explained and now my engine works much much better. thanks for the good info. on my polo, it was a little different but the basics are the same.

[@texasrick7327]

Ace video. Thanks for sharing this technique. This is definitely a job needed to be done on my Cupra, so will have a go at it now i've seen what to do! Thanks again.

[@RedlineRevs]

Glad you found this helpful, thanks so much for commenting.

[@user-cj6jk7pr6g]

Such a good repairing ! Thank you

[@EdtheGardener]

Nice one. Hope this helps fix my golfs hesitation at low revs in 2nd

[@dmr9042]

Thanks. I was scared to clean it bcos of recalibrating it later. Now I know how to do it without that.Thank to you.

[@ferenczhucker4561]

Very helpful video, thanks redline, but to give myself more room to manoeuvre, I’ll disconnect the breather pipe, it’s only the cost of a circlip , but keep sensor connected

[@BoogyW0ogy]

I Just taken my Throttle Body off and unplugged it and everything seems fine... Idk, if its because i have a tune on my 20th AE, but it works totally fine. with out re calibration.

[@davesicesisacrook3152]

I had a control difference intermittent error on my Octavia 2000 1.8T and unplugged the 7 pin plug to clean it. I had no problems with having to recalibrate afterwards. I read elsewhere it recalibrates automatically. It's also safer to unplug the lead so there's no power to the throttle motor. Mines a bit different to yours it has a manual cable on the side of it. Yours looks electric only. I like your video.

[@mariustanase4195]

Yes, indeed. But if you unplug it you will end up being unable to clean the valve in the open position, correct? I am also afraid to clean my throttle while still connected, but I'm also guessing that the most problematic deposits are around the valve edges.

[@zanemassie3203]

Yes that's what I ment thank you already ordered thank you very much for your help

[@RedlineRevs]

No problem, Zane. Thanks for your support.

[@misfit67]

Thanks Man for the help.

[@la1negrita]

great job!

[@Landaultd]

Nice, will help me with my A6 1.8 with AQE motor.....

[@fletchermusician3365]

Once again I have to BIG UP REDLINE REVS!! your videos have saved me lots of ££££ still got my Mk1 Audi S3 8L Thanks to you Bro....

[@ferenczhucker4561]

Thought I’d check what advise, if any ?, I could find on cleaning throttle body on my Seat Leon cupra before I started, glad I did, my first mistake would have been to completely remove it sensors too, didn’t know it would have needed calibration if I had, but what would be involved in recalibration of the throttle body ?, thanks, Ferry.

[@dub6358]

What’s the part number for the pipe you put the sock on? Mine is starting to perish so will need replacing. Great video, will be a great help!

[@danlammiman7826]

Great video - another thing on the to do list 😂

[@danlammiman7826]

Update - just cleaned my throttle body on my 1.8T TT the difference is night and day. Much smoother and and responsive!! Great video guys

[@chrischalcraft7938]

Oh I’ve learnt to use a Phillips screwdriver to remove a gasket from a flat surface!!

[@laszlovona]

or to remove a charge pipe without worm clamp completely loosened ;). no hate intended, we all do things by different means or different way.

[@mizrrainlias7759]

hi there, I looking for information I scan my Audi tt mk1 and in the scan appears this ¨p1297 connection charger-throttle valve: pressure drop¨. I want jus to be sure if this is the solution for this code? or if you have any suggestion

[@HUB1987]

so i seen loads of videos of people taking the thing out and unplugging the breather hoses and plug then cleaning it properly in a buck or whatever but whould it loose programming if the plug is removed?

[@RedlineRevs]

James Hubbard thanks for commenting. yes it will need to be recalibrated IF you unplug it. It's possible to clean it effectively without unplugging as I've shown in the video.

[@michaeldeguzman8675]

Is the throttle body different for the diesel or practically the same? Asking for a buddy that has the diesel. Also, why couldn't you push the butterfly valve to clean the other side of the throttle body? Is it electrically controlled? Do you risk damaging it if pushed? I just found it peculiar having to remove the whole assembly and put the car on ignition 1 to clean it. I've cleaned the throttle body on my Camry and just pushed the butterfly valve to clean either side. Thanks for an informative and thorough video.

[@socalguy829]

diesels don't have throttles, they are controlled by amount of fuel, not amount of air. the throttle body is electric in this car (except on early models) so it will damage it if you just push it.

[@PompeyMatt17]

@@socalguy829 yees they do !... it regulates the airflow intothe EGR....

[@NicsElectronics]

Gasket should arrive tomorrow, hoping to notice a smidgen of a performance increase.

[@carterandrea1994]

good vid need to do that too

[@RedlineRevs]

Thanks for commenting, hope this helps!

[@MrESCO9989]

Redline Revs - Great instructional vid mate, quick question, My 1.8t revs bounce on idle, would this help?

[@RedlineRevs]

It's worth trying, but also check your MAF: kzbin.info/www/bejne/oIbSgKGgfKh3fsU and engine coolant temperature sensor: kzbin.info/www/bejne/bXrUoWulhdiHh6c

[@clapper2trapper481]

Hi my skoda mk1 sometimes sticks at 2000rpm to 3000rpm could this be down to this part

[@mariustanase4195]

I'm really afraid to clean the valve on the edges with the contact on.isn;t there a risk to create a short on the motor of the throttle caused by the cleaning liquid?

[@emotionalintelligence776]

Your question shows a lack of understanding why you'd use a carb cleaner or variant but better to ask than not. First it's a mechanical device, not an infant and altho you can break or fudge some things yes CS usually will keep you safe. There are different types of cleaners with some being able to be directly applied to electricals while some can be used indirectly as long as it dries completely before using.

[@nickmaille5951]

Why did i even watch this there is nothing wrong with my car

[@smiffdogginit]

🤣🤣

[@Sirintegrahellsing]

Okay so I have a few questions regarding my 2005 GTI 1.8t. I will be cleaning the throttle body the correct way thanks to you guys. The issue that I’m having with it right now only happens when I fill up on gas (I don’t over fill) After a fill up and I start my car, it will start up at normal rpms but then immediately drops down to 300 rpms and I have to give it gas until the rpms go back to normal. Then the car runs perfectly fine until I fill up again and then does the same thing. Could it be the throttle body? The fuel injectors? The whole EVAP system? Idk and I hate guessing because I don’t have as much money as I’d like to in order to guess with. So I really need help, answers, anything... It just really sucks!

[@RedlineRevs]

Hi thanks for commenting. You could still clean throttle body but I would also try coolant temperature sensor: kzbin.info/www/bejne/bXrUoWulhdiHh6c

[@Sirintegrahellsing]

Redline Revs Thank you for your help, however, I’ve already replaced that sensor a few months ago, the car still has the same issues. My big guess is that it is emissions related, could it be the charcoal canister? I should also add that every time I turn the car off, I hear popping in the gas tank area. I just replaced the fuel pump and filter quite recently so it can’t be those. There must be a leak somewhere that’s allowing either too much air or not enough gas.. I really don’t know

[@RedlineRevs]

Have you tried MAF? kzbin.info/www/bejne/oIbSgKGgfKh3fsU

[@Sirintegrahellsing]

I have not, But have been meaning to.

[@homerog4920]

Evap sensor ontop of intake manifold or pcv valve ripped

[@ouzou7]

every how many kilometers i have to clean this?

[@jamieosborne9181]

Hi i have a seat leon cupra 2001 it has flat spots in 1st 2nd and 3rd gear will this help if i clean mine and if i dont disconnect the electrical clip it wont need reprogramming?thanks.

[@RedlineRevs]

Jamie Osborne hi, thanks for commenting. I'd say it's worth a shot. And yes, leave it all connected and you won't have to reprogramme.

[@MeesNaguMuiste]

do you need to disconnect car battery before this job?

[@CarlosTilbury]

hi chaps, great video, used it to clean the throttle body, but I still have the same issue as you described, I changed the plugs, cleaned the airfilter and re charged it and changed the MAS with a new one, but still get the flat spots, if I unplug the MAS the problem goes away, any idea?

[@RedlineRevs]

Did you change MAF with genuine bosch unit?

[@CarlosTilbury]

no, but the problem was there with the Bosch one too, infact it was even worse with the bosch

[@RedlineRevs]

@@CarlosTilbury try new original MAF from TPS. They were a sensitive and weak component, euros reconditioned ones can sometimes go wrong.

[@CarlosTilbury]

@@RedlineRevs will do, thanks for the advice!

[@CarlosTilbury]

@@RedlineRevs found the prob, bloody hose had come loose and not connected properly, work 95% but its due a service so that should sort it

[@dylanmason2373]

Any body have the part number for this please. Thanks in advance!

[@adognamedcat13]

great vid this will help my audi. But that outro..."comment, RATE and subscribe?? This was posted in 2017 not 2007!

[@RedlineRevs]

Elliott Fisher thanks for your comment I'm a throw back to the old skool KZbin, actual how to videos rather than vlogs about my personal life, low quality shaky cam production and yes, 'comment RATE subscribe', it seems to be working well for now!

[@69DSK]

how about the dirt that dripped in the alternator?

[@antharding]

And the carb cleaner on the belt! Other than that very useful.

[@chrishutchinson794]

Hello. I have a cold air intake on my car. Same engine as the video, and I drove around with the filter off for a while not knowing. Bot, it's hard to start when it's cold, and I have no idea how to clean. I did what this video said, and it's the same problem after I was finished. Can someone help?

[@danielbradbury9495]

Chris Hutchinson did you check if the air temp sensor is clean and plugged in? Try cleaning that too.

[@chrishutchinson794]

@@danielbradbury9495 I got it fixed. It was the coolant temp sensor. Changed that, and it started right up.

[@lupm7537]

First and foremost disconnect the battery before cleaning anything that has electronics on it and avoid expensive lessons.

Hi there will a 1.8t engine fit on a Skoda fabia mk1

Hi my throttle has stoped working the car starts up but no throttle at all any help plz it an audi a3 t150 2001

I have the same problem. Did you find a solution? Gr

[@jymmydkid5633]

What if my unit chatters when key is on and won't start

[@MatejLenart]

Dude literally covered the hose with his sock😂😂😂😂

[@jackbennet8319]

Why wouldn't you take the throttle body off? Would be a lot easker

[@jackcolwell3948]

Because if you disconnect the throttle position sensor (even if you disconnect the battery) there's a chance you may have to use vagcom to recallobrate the throttle body.

[@driva9457]

Ninja Turtle face in throttle body lol look

[@zanemassie3203]

where do i get that plate in front of the throttle body ?

[@RedlineRevs]

Zane Massie if you mean the gasket you can get it at your local TPS and probably also eBay.

[@seanlyons161]

I couldn’t find one on Ebay. So you have a link to one. Cheers.

[@R3vokedGaming]

Just ask your local auto parts shop...

[@zanemassie3203]

no i mean the little shelf covering your hoses and where the dipstick is sticking out of. the stock black one is ugly as heck

[@RedlineRevs]

Zane Massie you mean the black shelf next to the inlet manifold where the dipstick sticks out? You can get one of those at TPS, eBay or someone breaking the car. When I had mine off I washed it and resprayed it black to clean it. You could try another colour.

[@alwajeehhelal2125]

do i need to reprogram the throttle body after cleaning ?

[@RedlineRevs]

Not if you follow this method exactly. As long as you leave the switch at the bottom of the throttle body plugged in as you clean it you will be fine.

[@fuent35]

Alwajeeh Helal did you already tried?

[@razvan.c2711]

mi car is not starting anymore

[@swfcnumber1wawaw69]

Not tight on buying a replacement gasket but too tight to have a flat head screwdriver

[@dustinmckay2790]

This hurt my head just to watch

[@rickybee4537]

need some tools?

[@mickobyobrien2650]

Can you use the old carbon gunk to brush your teeth 😬

[@shootingDavies]

1. It wasn't dirty, 2. still carbon in plenum chamber 3. insert bolts into throttle body, then place gasket on bolts, having cleaned mating surfaces of course 4. Loctite blue on bolts and torque to correct value 5. think about buying some proper tools

[@xplicitmetal]

That was painful to watch.

[@blakkno666]

Why?.. not having a go, just wondering..

[@shanetravis8680]

It's a bite of a lazy way of doing it? Your where taking the throat of any ways so why not clean it once you've taken it of ? You still have carbon around the plate if you use a screw driver you'd be able to get it of you shouldn't be able to see and light coming through where you mist the bits
