Machines | DIY: Volkswagen MKIV TDI PD BEW Anti Shudder Valve Removal
videos | at work | information | view | construction
Video tutorial on how to remove the anti shudder valve (asv) on a VW Golf, Jetta, Bora, MK4 TDI PD BEW engine. Some other models that came equipped with a PD100 included some Skoda models, Audi models, and VW Passat. After a while of operation, the anti shudder valve does build up with dirt and debris which does need to be cleaned. Anti shudder valves can also malfunction over time either getting stuck open or closed, therefore not allowing the engine to start. The original function of the unit shudder valve is to prevent a "run-away diesel" and to allow for quieter engine shutdowns. This particular tutorial was done on a 2004 Volkswagen Golf TDI.

Why would you want to remove the part that protects your engine from runaway? If you're lacking horsepower, just get a more powerful engine!

i just unscrew the "disk" or "flap" on mine so far so good. way better TORQUE, HP and gas pedal response... the only side down is when you shutdown it shakes a bit, thats all. so i'll be running it like 2 weeks and check the dirt inside.

hey, im wondering if this part not working is causing my tdi to blow tons of smoke and no power

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.

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 youtube.com/watch?v=WnBkgxkIPgw 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
-
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

@tonybro70 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.
