- How to clean the throttle body assembly from a Volkswagen Golf Mk4 (03). Make sure the engine is off for this process, but that the battery is on for turning the valve. This should be routine maintenance.
Do not follow this clowns advice. Take the throttle body off and clean it properly
+James Shepherd hey, do you happen to know what EPC(electronic power control) light is? and also when engine light is blinking on passat 2010. my car is basically shaking. the engine is shaking like crazy when its started to be specific. and its very rough when i rev it around 10-50km and really really rough and car even jerks or jumps above it 60km. i checked on google and still looking around youtube. and its weekend and my dealership is closed -.-
Lmfao it’s awesome when someone else says exactly what I was gonna say in exact words 😂
@@calvinwong365 yo it's been 3 years since your comment but now I'm having the same issue with my Golf mk4. Have you found a solution?
Thanks bro I wish I'd read your comment I've fucked up my ecp
You're a fucking clown mate, my cars fucked now
Just did this to my 04 Jetta (GLS, gas. Not a TDI or turbo). P.S. DO NOT START THE CAR. JUST HAVE THE KEY IN ON POSITION.. AND USE A TOOTHBRUSH / MICRO FIBER CLOTH.. DO NOT USE PAPER TOWEL / TOILET PAPER OR WHATEVER.. I was getting horrible gas mileage before, and upon cleaning the throttle body, I was surprised to see a giant blob of black gunk behind the plate. After cleaning and putting it back together my milage went from 400km a full tank to 550 in the city.
Don't use paper towels for this, period. Use a lint free cloth, microfiber, clean shop towel, etc. You know all those little fibers that are left on the mirror when you clean it with paper towels....they are now in your engine.
I'm too late on that. Will it cause major damage?
Any contaminant has the potential to cause damage, many small items that find their way into a cylinder can cause damage over time, or burn on and create carbonised hot spots, that can also lead to a burn through of the piston head/s in extreme cases. Chemical cleaners can strip the cylinders oil layer and cause long term damage to the cylinder liners.
@@wadilious It will burn off and go out with exhaust gases. So small pieces will not cause any harm.
best to remove it and give it a proper cleaning with a tooth brush
Many of the comnents I have read are at best thoughtless, and at worst somewhat devoid of common sense. As most of you may know, do not treat this as any definitive answer, as in the first instance the throttle body can be housed in and mounted to the engine differently, secondly and very importantly many of the latest mk4 models do not even have mass airflow sensors, so don't waste time overcomplicating things, as many of your cars may not even have one. My car had the same problem and then some as it was so bad the car would go into something like a limp mode if trying to accelerate from stationary position or very low speeds. All I did was to remove air filter, turn ignition to second position, wedged the accelerator pedal, then sprayed throttle body cleaner, (carb cleaner) directly into throttle body, and it's run perfectly ever since. Maybe stating the obvious but I would also check plugs, filters and all things related, and imo I would always begin troubleshooting with cheapest potential fix and work upwards, as most mechanics will offer the oblivious the dearest fix. Finally, if only people employed a little basic common sense when putting up these demos under the guises of informing others, as there are many variations of this car irrespective of when they were made, so indicating the 'specific' model seems like a 'no brainer'.
Mellow- D so what if your flap doesnt open once wedging something on the pedal? Im driving a MK4 Jetta VR6 and recorded the throttle body flap stay stationary although I had turned key to the ‘On’ position
Thank you! Please make more videos about this engine!
agreed!!!!!!!
nooo! DO NOT have the car running while you do this, just have the battery on so that the gas pedal moves the valve. If the engine is on, this fluid can cause damage to it.
is it true that carb cleaner does absolutely nothing to cleaning the vw passat throttle body?is it a noticeable difference?i'm changing my battery tomorrow and they told me that by doing that it will reset my throttle body adaption then i have to use vagcom to reprogram
Franco MG what if when i press the gas the throttle valve doesnt open?
Omg car running smh
You undo the 4 bolts and remove the throttle body and do it RIGHT
William Fischer remove throttle body for a spray and clean ?
Just a thought, as I have a MKIV as well. If you install a small oil catch can in the PCV line, you can eliminate a lot of the oil that contaminates the throttle bore. Also, you'll notice a lot of oil contamination in the intake runner from the air filter. I pulled my intake to clean the injectors after 118,000 miles and 11 years. A lot of sludgy oil in the intake portion bolted to the head. Then I installed the catch can and it works very, very well. I used an inline filter that already has the 3/4" barbs that fit the PCV hose..Jabsco 36200-0000 In-Line Strainer and two clamps. Good video, thanks.
can you show me which one is PCV in my car, I have mk4 V5 2.3l engine AGZ, please
Can you put some link of this oil catchcan ??
Hi, I have a question: I have a Seat Toledo (1.6, 16V - VW engine basically) and when I turn on the ignition and hit the gas pedal the valve don't rotate to open position.. is there any "trick"?
You should really reset the learning data for the body in the ECU, while it will slowly adapt to the new limits a proper reset and adapt process will be much more reliable.
Dennis Lubert how you do that asking for my brother he own one of this
@@315streetscene8 You need VCDS or similar diagnostic software, there's an option for "Throttle Body Adaptation". There are other videos here on UA-cam that cover this, I think either Humble Mechanic or ThomasEXOVCDS has a how-to on it.
My mark 4 1.6 16 v has the filter on top of its engine no side air filter box like yours is there a video somewhere of my engine procedures for this job?
Remove the air filter, and two attached breather hoses from the air filter box, then the throttle body assembly resides at the top right of the engine, without having to remove any other parts. Be careful not to spray too much fluid into the throttle body housing. clean with a non lint based cloth spray cloth with fluid, NOT tissue or loose fibre cotton. The most important part of the cleaning is to ensure you clear any obstruction from the horizontal lip that the gate sit almost touching when idling, without the right gap space between valve body and valve edge, the engine cannot breathe causing the fluctuating rpm.
Did it throw a code before you cleaned it or did you do it just to do it?
Anna calderon No code, I just did it.
so, we sprayed the cleaner plus the dust and dirt into where?
I'd say it's most likely that the cleaner + the soot/grime will end up in the cat, and reduce its lifespan. It sounds bad but but I don't see where else it could go on the closed exhaust system.
You remove the throttle body and clean it properly.
If the TB is on the car, you do NOT spray that cleaner into the TB and you do NOT use a paper towel. You use a microfiber towel and spray the cleaner onto the towel.
Hi i want to know if the car was on idle while spraying the cleaner?
Excellent video !
Please, a video of where the map sensor is, I have a golf like it.
Those Bosch and VDO throttle bodys are bad! Replace it with a other good brand throttle body
guys help...I am dealing with "throttle counter" problems according to the code reading...I added the cleaning stuff to the gas in the tank but the problem seems to be getting worse...i'm thinking whether it is because of the cleaning I added or is the throttle counter just dying away...is there a way to clean it by hand..or check if its really dirt on the insiide that is killing it?
1) DISCONNECT YOUR BATTERY (SAFETY FIRST)
2) REMOVE THE AIRFLOW BOX
3) DISCONNECT THE DUCTS FROM THE THROTTLE
4) REMOVE 4 ALLEN TYPE SCREWS FROM THE THROTTLE
5) REMOVE THE THROTTLE (be careful with the gasket, unless you have a new one)
6) FREELY (avoid any sensor or in this case the black plastic area of the throttle)APPLY THROTTLE OR INTAKE CLEANER TO THE METAL AREAS
7) WITH A CLEAN MICROFIBER CLOTH START TO CLEAN UNTIL THROTTLE IS FREE OF DIRT IN BOTH SIDES.
8) CHECK AND CLEAN WITH THE SAME CLEANER AND CLOTH THE DUCT THAT CONNECTS TO THE THROTTLE AND THE AREA THAT THE THROTTLE IS ATTACHED.
9) RECONNECT EVERYTHING AND TURN ON THE VEHICLE (leave it for about 10 minutes).
10) UNDER ANY CIRCUMSTANCES DO THIS WITH THE BATTERY CONNECTED, IT COULD DAMAGE ANY RELATED SENSOR OR THE COMPUTER (this guy was lucky), ALSO, AVOID USING PAPER TOWEL AND NEVER EVER TRY TO CLEAN THE THROTTLE WHILE THE CAR IS ON.
what is that sensor on the air intake pipe side, has 2 pins? my car has the cable but not the sensor
good work !! thanks for all..
Great video will def try this
Tools required?

Hi i want to know if the car was on idle while spraying the cleaner?
DO NOT run the vehicle while applying throttle body cleaner. You should only turn the key to the accessory position, so the throttle body valve responds to the peddle being operated. It's way easier to clean when it's open, without having to remove the entire throttle body assembly. I was once told by a wise and old mechanic, DO NOT open the mechanism by hand. Also allow the excess fluid to evaporate before restarting the engine. It's inclined to break down the oil seal within the cylinder and around the piston rings, especially if you spray too much fluid into the engine.
You have to take the throttle body off to clean it.
You have to program the throttle body to get recalibrated again through the computer though. Cos if you took it off and don’t get it calibrated, you get all sorts of problems and the car will be off the road.
Thanks Franco..appreciate your help
what could be the reason my car over heats it just had a full service also had a new water pump should I buy a new thermostat please some one with knowledge let know what too do thanks.
eminem 2pac check that the timing belt is in correct position
Junk it
Very good... Use Gloves!!
just take the actual throttle body off. much easier and use a fucking toothbrush instead of paper towel
Hi, i done this to my car still idling mate? any help?
Poo p olii
iMortalProductionzHD most likely have a vacuum leak somewhere
Thank you
Hello
Can you help me with the second sensor near the gate, what is its name and where the cable is heading in the car
Thanks 😁
NICE ONE !
You cant clean it right without removing it. Maybe 70%, but this isnt enough to fix problem.
Hello I have a problem with the smuggling of oil Sarvo what are the reasons
I done exactly what you done but after 30 minutes its still driving rough ? What do i do now ?
Why clean throttle hole,it's enough large to consume all fuel from tank ( it is very large and expensive to fill at top).
Wart driver was youed too remove body
so taking off your air filter and spraying oil into your engine is a good idea?
wipe up the oil, don't spray it all the way in.
hey i just purchased a 2002 vw beetle. After about an hour on the highway, the car stalled and i cranked the car a few times and it started. I drove another 20 mins and it happened again. It does it randomly now and then. What are the isses, i don't think it's gas or fuel pump. I runs great and is arching out from a bad plug wire but is fine. I have to fix that wire too. I've read about the crank position sensor, Idle speed control or maybe my distributor is worm from the arching. I'll clean my MAF but don't think that's it.you've done these cars 100 times over, what do you think. it runs great ,on the highway going 60mph and it just stalls.
iys the coil packs commom problem, google it
mike shiva WA
Its 100% a fuel pump
Hi did you ever get help my car is giving me same problems
