Diesels don’t have throttle plates or bodies to control the air flow which in turn controls the rpm of the engine. Their throttle is controlled by the fuel adding into the motor.
Throttle body
The anti-shudder valve, when closed, is basically what causes the engine not to start, or causes the engine to shut off because the valve controls the air intake. As far as I’m aware, certainly on my vehicle, if I was to remove the EGR valve, I’d be removing this valve as well, because I understand the ASV is physically part of the EGR unit.
Not a bother at all 🙂 I posted a reply on your video.
Nice video 4Diyers, i will also try this. Sorry if i am bothering you, check out my problem/sounding engine

Tnx
Nope, that’s the Anti Shudder Valve on the PD engine. On the ALH which is the older model diesel, the EGR Valve is in that location.
Anti shudder valve? Don’t you mean EGR valve? Correct me if I’m wrong
you would need a spring loaded block panel, over the intake horn. like the pulling trucks have. pull a pin in hte dash, lock the moving plate in place will block ar flow coming in to teh engie intake. there fore choking the engine. if oyu remove the asv, you need another way to stop the engine. unplug hte battery possibly. or shut off the power to it.
Have you aligned the shift cables in the car??? That would make the car hard of shifting or not engaging in gears.
I have a VW Golf 4 manufactured in the year 2000. Its change of gears is not smooth. I have changed the Gear box twice but the same effect-(hold up and subsequent release) and at one time the engine ran but engaging gears failed. what could be the problem
The purpose of the ASV is to prevent a “runaway diesel” and quieter engine shutdown. The advantage would be better airflow. The disadvantages would be no safety for a “runaway diesel” and you’ll most likely have a check engine light, so you’ll need your ecu edited to remove the code.
What is the purpose of removing the ASV? What are the advantages/disadvantages?
thats okay i got it , it was just the egr system which blocks the valve cover from coming off , you can remove it without any issues . thanks anyways
I never had to remove the valve on my car, but from what I’ve read, you’ll have to turn the engine over in order for the cam the clear valve cover. Other than that, I don’t believe anything else needs to be removed.
i’m just trying to replace the a leaky valve cover gasket . My engine is identical to the one you see in this video here , you can see in this video that intake system is blocking the valve cover from coming off , once you get the screws off of course. my question is difficult or should i watch out for certain things when taking it off , i have a manual but it doesn’t really cover this , thanks
Is the engine a PD or ALH diesel??? Also are you trying to replace the upper intake gasket or just the valve cover gasket???
This valve is to prevent a “runaway diesel” and also reduces the sound when the engine is turned off.
hey thanks for the tips , you seem like the right guys to ask about about removing that air intake system , trying to remove the valve cover to replace a gasket and this things in the way , don’t want to remove it until i know a little more , you guys have any suggestions
Nope, I never had any trouble with mine… Possibly there was dirt in the head, so you might not of had the allen wrench in all the way. It’s a real pain to see that spot and it’s fairly tight too. You can probably just drill the head, remove the unit, and then put pliers on the remaining stud left. I’m impressed that you cleaned it on the car… I would have never had the patients for it lol.
Just wanted to ask if you ever had any trouble with stripping the heads of the allen bolts. I got the top two out, but the bottom (and hardest to see) stripped and I couldn’t get it even with an easy-out. I ended up trying to clean the valve while still on the car. Frustrating, indeed.
It’s called a doggie collar. I have it. You can search it from kermatdi.com
I think even with a new one, it will wear over time because it doesn’t hold tight like something that is bolted together. So it probably would work for preventing the pipe from wearing out also.
I’m actually about an hour north of London.
not a bad idea, nad yea it does beat spending $100. I’m from Caledon, a bit north of Brampton, south of Orangeville.
I’m actually from Ontario… I had to take ASV off to clean it and fix the pipe that keeps popping out. I saw a member from TDIClub used grub screws to hold the pipe in, so I’m going to do the same thing. Beats spending $100 on a new pipe lol.
I’m guessing this was for cleaning purposes? Where in Canada are you from?
