Good video, thanks for positing it. Just did this on my 2007 ML320cdi. The flaps can be stubborn to rip off especially with the greasy mess inside the intake. Just keep twisting and the flap will tear off. You need to remove the six white plastic keepers then pull the flap shaft straight out. Use a wide blade screwdriver to gently lift the white shaft keepers and they should slide out. I broke one keeper and spent extra time breaking up and prying out the plastic root. I used a fine thread 3/8" tap and installed grade 8, 3/8" x1" bolts with plenty of thread lock after cleaning the intakes. The tap will bottom out at about 1" inside the hole because the flap shaft tapers near the intake hole, don't force the tap and break it off! Also, if you have a later model OM642, the swirl flap linkage has position sensors and will throw error codes if they are removed. You will need to do your own research for proper work arounds for the linkage sensors on swirl flap delete for the newer models. This is different than the swirl flap motor delete resistor.

All six of my white shaft keepers had turned to petrified rock, that was the hardest part of the job, breaking them up into bits and extracting them.

@@BrageGundersen pretty sure 2010 and up models that are bluetec have the swirl arm position sensors. If you have the swirl arm position sensors and want to delete, there may be a way to connect the linkage back to the new arm block off bolt using a new linkage arm kit and some custom fabrication in essence leaving dummy linkage arms that move to satisfy location sensing. This maybe easier than reprogramming workaround.

What about swirls flap actuator? My one is broke engine light is on if i remove flaps is there way to by pass that think so car drive or better to just change it and drive. Car is stage 1 remap and in limp mode atm

@@cibo9994 it's mapped and still in limp mode? Weird. My tune got rid of the motor being necessary. Check forums. You can add a resistor on the harness where the motor plugs in to trick the computer in thinking it's still there. Then you just need to figure out how to hold the flaps open vs pulling the whole manifold to pull the flaps permanently.

Seems like a good idea but definitely not a good idea. I’ve been working on these for a little bit over 15 years…. There’s a lot of context missing from this video of why and what will happen after you do this in certain situations. It’s fine in this situation because you have no sensors. But if you do this and you have run sensors, your truck will never run correctly again.

They will, because if they are broken, they will not work properly, so either way you get more air flow from them if you remove and bypass the sensor

This version of the om642 (citation needed) only has a servo motor that moves with no sensors. Which is why it works. And you mean to tell me that you've been working on these engines since they came out but came to my video for help? 🥰 Glad I could be of assistance!

If you want to remove or make the swirl flaps (butter-fly valves) inoperative you have to fool the system into thinking the valve motor and sensors is working properly. I suppose it's possible but I don't see how. I believe the best thing to do is remove the heads, clean them also then clean the intakes. Then it's back to original and working as it should. Run a carbon remover regularly.

From what I read back when I performed this, is people put a resistor where the motor goes and it thinks all is well. Since there doesn't appear to be any sensor indicating position. But yes in an ideal world I would pull the heads. But that's an absolute ball ache with this engine. It was already 8 hours to get to the oil cooler 😹

I currently have the manifold off the car at the moment. I cut out the flaps and the rods. Shortened the rods and then blocked the hole at the bottom, so in turn all parts work properly but there just isn’t any flaps inside the manifold.

According to a lower comment, your mileage may vary on just using a resistor to trick the computer. Mine was already tuned for EGR and dpf, after pulling these it didn't throw a code... So I guess it's also tuned for that as well

It runs the same, it's more or less a preventative maintenance, because it's only a matter of time until something happens with that motor or the brackets break
