How to clean vacuum valve air filter in 1.6 & 2.0D TDCi, HDi engines (Volvo Ford Citroen Peugeot)

Vacuum valves in 1.6 and 2.0 diesel engines (Ford, Peugeot, Citroen, Volvo) control throttle body flaps and variable geometry turbocharger (VGT, VNT). If the air vacuum valve air filter gets dirty and clogged, its performance will drop. This can cause power loss, trouble starting the engine and shaking when turning the engine off.
Cleaning the air filter is not complicated - do it yourself in your car. Watch this tutorial and check how to clean it to increase this elements performance.
Engines 1.6HDi, 1.6TDCi, 1.6D, 2.0HDi, 2.0TDCi and 2.0D (DW10 BTED4) with this Pierburg vacuum valve can be found in cars:
Citroën Berlingo, C2, C3, C4, C4 Picasso, C5, C8, DS3, DS4, Jumpy / Dispatch, Xsara Picasso;
Fiat Scudo, Ulisse;
Ford Focus MK2, C-Max, Fiesta, Galaxy, Kuga, S-Max, Mondeo MK4;
Lancia Phedra;
Mazda 3;
Mini Cooper D;
Peugeot 206, 207, 307, 308, 407, 508, 607, 807, Expert;
Suzuki SX4;
Volvo C30, C70 II, S40 II, V50, S60 II, V60, V70 III, S80 II

Jesus, never thought that a dirty sponge could make this difference. My car was acting like an old school diesel with turbo lag, and less power overall. No codes, nothing. And also frequent DPF regens. Cleaned that sponge and car came back to life right away, and DPF regens back to normal. The sponge also started falling apart, and I've replaced the solenoid anyway.

Mr Fix, I owe you a drink. I was ready to buy and fit a new vaccum valve and Googled the part number. This is how I stumbled across this video. I am stunned that by following your instructions, my car is now running fault free, with the fault code P0234 (Overboost) now gone. I genuinely cannot thank you enough 👍

[@DaHitch]

Thanks for the video! When told my power issue was likely caused by the TCV I was not looking forward to digging near the firewall to find it. Fortunately I could tell from the video it's mounted near the front of the engine and it turned out to be a 5-minute fix.

[@michaelcooper3826]

[@mrfixpl]

yes, it looks the same. If I remember it's located somewhere between alternator and AC compressor. If you have throttle body flaps related problem, you can start with disassembling and cleaning it. Also you can check with a syringe if flaps move freely.

[@stefanzdraveski]

Hello my Mondeo mk4 2008 2.0 tdci 140hp had two of them. I had strange buzzing noise when turning engine off. Then it started kicking when accelerating which made me check whats going on. I noticed the one of the valves, close the intake manafold was making the noise, and i wasnt sure, but when i switched the two valves my car changed the sound, it was sounding more like whistling turbo sound and i knew that something was wrong with one of the two valves. So i put them back as they was and when i added more than 3000RPM the car went into limp mode with ESP light on with errors: P2263:73-27 - Turbocharger boost performance U0401 - Invalid data recieved from ECM/PCM My question is if you know.. Which valve controls the turbocharger? Is it possible one of the brown valves to make the car going into limp mode with turbocharger interferences? Are both valves linked together? Thank you very much i will apreciate your opinion on my problem :)

[@Dan-pq9wc]

Hey, my issue is that the throttle housing flap gets stuck after shut down and the car won't start again unless I disconnect the vacuum hose from the throttle housing. I removed the vacuum valve like you did and changed the sponge. After two shutdowns it was okay but after the third, it didn't start(hence the flap got stuck again). I also cleaned the throttle housing and it moves freely. What would you recommend I try next?

[@donfrancis1375]

Shaving the flaps down slightly. Sorry 5 months too late but for anyone else ot might help

[@azuzkharef2293]

Good

[@JB-pk8vm]

Please someone help me. I cleaned all the three valves and still have a power loss. First 3 gears are okish but then its a slow car. This happened after changing fuel filter and mass flywheel, there is no to little air in the fuel line. I ordered a new gas house inlet as I read that the valves sometimes break down

[@joesaric1]

Can inlet manifold swirl flaps crack or fall appart because of the invalid vacuum valve ? And if crack can it go throught the turbine exit and cause damage ? Can car than go on ?

[@mrfixpl]

I would say that it's unlikely that vacuum valve can damage swirl flaps. Anything in the intake manifold can cause damage to the engine and components.

[@georgigeorgiev1300]

[@nikolaigolchev9575]

Is there any difference on the way you connect the two vacuum lines to the valve? I did the procedure but I am not sure on the position of the two vacuum lines.

[@mrfixpl]

outputs are described. VAC to vacuum, OUT to device (turbo, throttle body, EGR...).

[@nikolaigolchev9575]

Which one of the lines is vacuum and which one is device? Is the upper line going to the OUT section and the line that comes from the section near the fuel filter going to VAC?

[@mrfixpl]

What car? Which engine? What's your valve controlling? Best if you follow the lines. You will find that all VACs are connected with each other, and OUT lines go straight to devices.

[@nikolaigolchev9575]

The car is Volvo v50 2.0d and the valve is the same as the one in the video. I am not able to see in the video which goes to Vac and which goes to Out. That is why I am asking if the line from the upper part of the engine goes to Out and the one coming from the side of the fuel filter goes to Vac.

[@mrfixpl]

OUT goes to turbo. that's the line that goes between engine and battery, then behind the engine under the EGR valve. VAC goes under the intake manifold.

[@rl1372]

Sir, can you tell me why my boost gauge shows "-1.0" bar? I use an app. call "torque" and obd2 bluetooth device to connect and show them. My car runs normal.

[@mrfixpl]

When you have -1.0 bar boost? Idle, normal driving, full acceleration?

[@westjian]

mr-fix Sir, it just stay at -1.0 bar when start up. The funny thing is when I hit the throttle, it, sometimes, can reach +0.3 bar. I got this second-hand car 2 weeks ago. The engine works..okay...kind of. Not rough idle and no strange sound when accelerating....(sigh) arrrrrrrr...I haven't try full acceleration...yet...

Like a buzzing for about 30 seconds after you turn it off?

[@MaitromediA]

mr-fix yes, that buzzing noise contuines about 10-15 sec. after turning off the engine.

[@mrfixpl]

That's normal. This vacuum valve is keeping the ink flap closed when you turn off the engine to help with stopping the engine. Then, after 10-15 s. controller shuts down, vacuum valve is powered off and the flap goes to default (open) position.

[@MaitromediA]

[@mrfixpl]

Replacing parts to trouble-shot no power issues is a bad idea. Best if you connect your car with diagnostic interface and check some live data from your car. Then you'll see if the fuel pressure is correct, air flow/temp/pressure, acceleration pedal readouts... Or maybe your VNT is stuck.
