How to remove, clean and replace the throttle body on VAG 1.8t engines found in mk4 Golf generation cars VW / Audi / SEAT / Skoda. Vehicle shown is a Skoda Octavia vRS mk1 1.8t.
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.
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.
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
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.
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.
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.
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.
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
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?
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.
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.
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.
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.
It's worth trying, but also check your MAF: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-jUoOnjGCDHc.html and engine coolant temperature sensor: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-7Iqp8oPsTQE.html
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?
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.
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!
Hi thanks for commenting. You could still clean throttle body but I would also try coolant temperature sensor: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-7Iqp8oPsTQE.html
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
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?
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?
Elliott Fisher thanks for your comment I'm a throw back to the old skool RU-vid, 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!
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.
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.
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
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
