- A guide how to clean the carbon deposited on the anti shudder valve of modern volkswagen tdi diesel cars , usually people think its diesel throttle body but it is not true , its just an air control flap which works just 2 times , once on starting the engine and second on switching of the engine , as diesel engine are famous to vibrate or shudder at start ups and shuting down , this air flap adjust the amount of air pressure in the air track to reduce that shudder or vibration , to make the engine feel more refined,
But after some time this flap gets some deposition of egr gases mixed with oil vapour from crankcase ventilation system and form carbon depositions , which acts as a restriction in the path od smooth flowing air and harms performance and refinement .
problem - car shudders while turning off the ignition
video made on a volkswagen polo 1.5 TDI , same method applies to volkswagen vento and skoda rapid , skoda fabia jetta , audi a3 , audi a4
but the process remains same for every modern diesel engine , just location of component change .

Thank you so much for your Video.I have a 2011 Octavia 2.0 TDI the engine has recently shuddered when turning off the ignition and then I had fault codes P0120 I told 2 local garages near me of this shuddering on the car and I said the throttle was the problem. They tried to charge me for a EGR assemble £1000 part and labour.which I refused. I thought this shuddering was to do with the timing. I am so grateful to you as I have found the problem. I can clean the part myself I took the top of the hose off and it is full of gunge. The car is 12 years old with 75,000 miles. I love the car and I can fix the problems. You are BRILL.
Thanks a lot for the video. I watched the video lot of times and tried this today. Took me 2 hours to do this activity :)
Hi sir, all are very useful and detailed videos for diy's. Pls add videos about useful vw scanner tools available online or market
how did you clean it without moving the valve flap? Is there a special chemical you used or would a WD-40 brand of throttle body cleaner work well for this?
Bhaai polo 1.2 tdi hai accelerator se pair hatao to ek jerk ata hai or rpm needle bhi jerk karti hai waise koi problem ni hai
Kya lagta hai aapko kya ho skta hai
Drivetrain lash-back hota hai sir ,
Hum thoda sa reduce kar sakte hai isko but poora khatam nahi kar sakte ,
Intake manifold , valve , valve runners , anti shudder valve , MAF sensor , egr valve , egr cooler and piping clean hongi proper tarike se , injectors bhi clean honge .
Dog bone mount ki condition ke according agar change karne ke need hui to wo bhi karna padega .
Insab chejo ko kar ke , around 50-60 percent tak reduce ho jaega .
I'm suspicious this may be the cause of my P0238 code. It was open when I hit a deer and it blew the main fuse. Car immediately shut off but the anti shudder valve never got a chance to close.
Mines been unplugged for a year because of issues. I'm not replacing it. I might make some plates and use a diode
Hi Sir
Am planning to buy used Vento Diesel.
After driving 2 Nos 1.6 TDI Vento Diesels and 2 Nos 1.5TDI I find that 1.6 TDI is more refined and has better linear response and lower engine noise level and lower vibration.
1.5 TDI seems to have in built lag when we race up from,there seems to be some delay in engine picking up RPM.
Once RPM increases then pick up lf 1.5 is more than 1.6
But engine sound at low RPMs in 1.5 TDI is more than 1.6 TDI.
Due to this reason I think I should buy 1.6 TDI
Do you also feel same observations
Sir , its not that simple , there are a lot of factors ,noise depends on, how well the car is driven over years
I already subscribe to your channel.. very detailed videos
If u replace the throttle body do you need to recalibrate it?
Yes sir .
@whitemanisgod no sir , it will give a light on dash 😅
Sir if you follow all the procedure like an egr delete , blanking plate and disabling it from the ECM as well then yes , it will increase the output , no doubts about it
Watched again😃😊
Hi, I have Vento 1.5 TDi 2016 model and I am experiencing low pick up from sometime. How was your experience of cleaning throttle valve. Did you observe any considerable difference after cleaning it. If yes please mention what did you observe.
Sir there was no difference in performance as its not throttle plate , its anti shudder valve , it only works when we shut of the engine
Those bolts are t30 not t25 always use right size tools
Yes sir its t30 , maybe i had told wrong tool size , but in later video i corrected it
Want to ask you a question i own a vento 1.6 TDI recently car idle goes to 1000 rpm and stays there on idle ..
Even Ac is off that time.
if you have any suggestions on this please suggest
Sir engine idle speed can be raised due to few reasons
1. If the timing is not accurate
2. If the ecu thinks that coolant circulation is not up to the mark , it will increase the speed to increase the circulation
3. If the battery has low voltage , speed will be increased to charge the battery quicker
4 . If there is load on the engine for which ECU has to compensate by increasing the idle speed .
5 . A faulty pressure sensor , which maybe providing a wrong data to the ECU about the barometric pressure and ecu things that the car is on a higher altitude and engine needs to be revved a little higher to compensate for the lack of air pressure
Hope it answers your question
@@yourDIYneeds Thnks for the suggestions ill surely try to diagnose this according to them.
Do the VW service center guys do this during a regular servicing?
No
The idiots at VW service are always clueless - better do it yourself not much of an effort
@@pinakidas397 😂😂
Yes , they just change parts
@Sriram Eranki 😃😛
Very useful
Hi, I have a polo 1.2 TDI. When foot off the accelerator during cruising the car jerks and the rmp meter just goes up and down a little. It's more evident in lower gears. What could be the reason. I have scanned the engine and no error codes. I have recently changed engine mounts and transmission mount.
Even i am having same in my polo 1.2 tdi Have you got any solution or reason for that bro ???
@abhishekordinsingh
Sir its called drivetrain lashback ,
All you have to do is cleaning, from MAF sensor , then piping then anti shudder then eger valve , egr cooler , intake manifold , valve and valve runners , and injectors as well .
It will get reduced around 50-60 percent
New cars don't have carbon deposits in the intake system , so the lashback is not that pronounced , but as it is driven it accumulates deposits thus more pronounced lashback
@@yourDIYneeds I'll try it out and will let you know. could you please tell me what you mean by piping? Thanks alot for the info
Sir i mean all the pipes and hoses which are in the air intake system , so that there is absolutely no restriction in the air track .
Would this cause a non start issue and car cutting out/stalling? If it was sticking at closed position...and would it move.e open close during driving or only closes to stop engine
Sir , it will just work when you will start and shut off the engine , rest of the time it remains fully open , but yes if it got stuck in closed position then it will leave engine starving for air . And can cause issues related to starts
Hi I have a 2009 vw golf 1.6tdi, I’m losing coolant but can’t see where it’s being lost from. I changed the expansion bottle but still no improvement. There is some oil leak but the garage could not locate the source of the leak either. Do you think it might be an EGR valve issue? No power loss, no smoke, the fan comes on more often and remains on more often so it’s over heating sometimes. I’m having to top up the coolant after about 150 to 200 miles on a regular basis. Any ideas ?
Sir 3 hidden places can be
1 . Water pump , as its buried inside the timing cover we can't see it .
2 . Oil cooler , it can leak internally but it will get mixed up with oil and you can see the sign's of that under your oil filler cap .
3 . Egr cooler , it can get leaked inside the egr cooler and due to heat , it will evaporate along with the exhaust gases
Last and the worst case , head gasket
Or it can just be a faulty coolant reservoir cap which is leaking under high temperature .
Hope it helps .
@@yourDIYneeds what an understanding 👏👏💥
I think I have changed the position of the flap , how to calibrate it ?
Sir either with VCDS or obdeleven
How about using liquimoly throttle body valve cleaner?????
Never used it sir
@@yourDIYneeds would like to know if using liquimoly for cleaning anti shudder valve does any harm 🤔. ? Your opinion on this
Sir as the quality of liqui moly on other products is great , i can really go for it without any worries
hy, after changing part do it need some adaptation/calibration by some software tool?
If you have not changed the position of the flap , then no.
@@yourDIYneeds tnx for the answer. best regards
Bro some yuotuber clean without removing throttle body and when they accelerate the butterfly flap is opening but in my polo it's not opening. Is it normal in polo 1.2 petrol manual.
Sir in vw , we usually have a soft limiter , so on idle it will just rev to a certain point and only a little of throttle flap will open
Tata safari me hota ha g pls answer g
Nahi sir
Hai Sir, around one year back I bought 1.5 tdi polo 2014 model KM 120k on the odo. Since I buy, the car is shivering a lot while I am starting the engine, then it is slowly slowly going to the normal vibration. May I know what is the reason for that. Thank you Sir. I appreciate for your useful videos.
Sir if you have bought a 120k kms vehicle on odo then there are alot of things you have to make sure that its perfectly reliable . As we don't know how the previous owner maintained it .
1. Annual oil change ( nomatter if the previous owner said that he or she got it serviced just a day before , do it again just for you own peace , untill unless he provides you with a invoice of authorize service centre )
2. After 120k kms alot of carbon deposition happens inside the engine , so we need it to be cleaned , use a good engine flush compound when doing an oil change ( not every time just this time )
2. Get your MAF sensor , intercooler , egr return pipe , intake manifold and anti-shudder valve cleaned ( it may sound alot but it takes only 5-6 hrs or say an afternoon )
3. Run a good diesel system cleaner along the fuel for atleast 2 tanks , so that injectors can get cleaned .
After all this you will feel the difference . It will be alot smooth , and use a good quality engine oil which has the approval of vw 505.01 that makes alot of difference how engine feels .
I have videos of all the topics on my channel , if you are a person who likes to get his hands dirty then you can save a lot on labor as well .
If its your first Volkswagen then i have a peice of advise for you , change your fuel filter on every oil change as we don't have fuel quality as compared to central europe , alot of people will say that its ok to skip the fuel filter but its not , injectors are sensitive to fuel quality ( no matter how much i stress this things , it will still not be enough )
Hope it helps 🙂
@@yourDIYneeds Thank you Sir
I am planning to buy a 2010-2012 vento/rapid tdi 1.6 can you please share you email ID for your consultation on what to look out for.... I just need solid reliable German sedan.
mine stays open and car shakes when on or off. Also has an hard electrical buzz on it.
Its supposed to be closed when you shut your engine off , get it checked sir , maybe its getting stuck
Could this be a reason for engine pulse at idle?
If its malfunctioning then yes , but it remains fully open when the engine is running
Sir i have 1.2 tdi and it has run 100k kms
And i am illing to do the liqui moli intake cleaner method can you please give a step by step guide cause i watched the video of liqui moly you told something about the sensor on the aur filter and I didn’t get that
Sir spray it after the sensor but don't forget to unplug the sensor
@@yourDIYneeds ok thanks a lot sir
@@yourDIYneeds will there we a check engine light after i put it back
Also clean the EGR return pipe.
Already done
Bhai throttle position sensor Circuit A performance range fault generated. Where is this sensor located ?
Sir throttle pedal itself
@@yourDIYneeds kya fix hai iska ? Part ka cost ?
th-cam.com/video/p4BSx0QL_5w/w-d-xo.html
Sur pehle adjust karne ka try kar lijiye , agar fir bhi nahi hota hai to fir part change hi hoga
@@yourDIYneeds due to this my engine knocks a lot rpm high low bhi hota hai idle pe aur pickup thoda low hua hai. So are you sure that this the sensor which is faulty and not some other sensor.
Hi brother recently after 700kms drive while coming back for about 150kms I pushed it little hard.. I am noticing my vento tdi is vibrating more than before at idle, vibration can be felt while sitting inside earlier it was not vibrating this much, while running no issues it's normal as it was before and also there is no rough idle or any kind of rough noise or knocking from the engine.. What might be the issue?
Sir try cleaning the air filter MAF sensor , sounds like a clogged air filter from dust which is making it hard for engine to breath
@@yourDIYneeds OK will do it, But I have just driven 1800kms after last service, do u think filter will be clogged so soon? Or it might be maf sensor causing the issue as u said, usually in general service maf sensors and other sensors etc won't be cleaned..
Sir air filter getting clogged totally depends upon the driving conditions, if you had driven in dusty environment then yes it can get clogged fast
@@yourDIYneeds Thank u..
Please Make a video of coolant flush n change in rapid tdi
Sir already on channel
Polo vento and rapid is same
Sir thanks a lot for your reply
Sir can u name the tools required In service
Can I use other than OEM fuel filter

Carbon ko ane se kese rokein egr aur anti shudder valve me?
Egr blanking is the only way

bro, petrol variant mein throttle kaha pe hota hai.
Exactly opposite
What is the Km reading of this car at this stage?
At this time it was 64k
Now its 68
