E320 CDI Rough idle caused from Malfunctioning EGR.

- EDIT: ALSO discovered swirl flap linkage came disconnected and was starving engine of air! that was the main cause!
Here's a video covering that: • OM648 Swirl Flaps Fix ...
Something is causing the EGR to open when the engine is warming up, which is causing the engine to misfire and stumble at idle.

The ACTUAL fix for this misfiring issue was with the swirl flap valves linkage! the EGR causing misfiring was just a side effect of the increase in resistance of air flow into the engine caused from the swirl flaps being closed. Here's my video on that issue: th-cam.com/video/8lt4IjzSYNo/w-d-xo.html
How we can get rid of EGR at home? Diy style.
Where can I get the bypass kit for the EGR ?

For what vehicle do you need an EGR bypass Владимир?
@@pfoxhound
What is the vehicle that you needed done on?
2005 E320 cdi
cant believe it. Removed several times to clean EGR. Replaced EGR valve. Get this. after watching this video, unplugged ERG. Drives perfect. Only thing is, Turbo doesnt respond when flooring it. So EGR unplugged. Will drive for 30 mins, 20 miles each day to see if it cleans up. then plug back in. Will put in some fule aditives too. Doing my complete head in, but will get there
I got a Green Diesel engineering tune. No EGR and better power and fuel economy. Very happy.
How?
EPA shut them down, they aren't selling it for our car last time I checked:(
Hi I have taking EGR apart to clean. Great to see your channel have the plastic cover off. After put it back I have noticed EGR that it keep on moving and unstable idle rough. So for my luck thinking carbon is still on the shafts making it hard to move smoothly, didn't take it off again. I have used Hot Shot Secret sticking eliminator on the shafts by let soak over 3 time during in between drive. This may fix it for now when start up no more rough idle. The code for EGR stuck open has not come back for 2 weeks. I have smooth idle but due use oil and diesel additive from Hot Shot Secret for over a 6 month. My car is E320 cdi 2006 is close to 100,000 miles. Thank for your video details repair of E320 cdi it gave me clear idea how to repair my W211.
Unplug the EGR and drive some miles on the highway to "clean" everything. Your engine will be like new.
You can keep it Unplugged and u will get better mpg and power.
I've had mine unplugged for 5 years as the solution to fix the car going into "limp home" mode randomly after scanning and getting the egr code. I tried installing a new egr that fixed the problem for about a week then back to limp mode.
Thanks for posting videos of this car. I have an 05 CDI (only 125k miles) and had issues with it going into limp mode/ CEL. I pulled the EGR valve and cleaned it out, but still had problems. I ordered a new one, and it ran great for about a week and back to same problems. I since put the orginal one back on and literally just unplugged the wire. CEL stays on but It runs great since with no limp mode and has for a couple thousand miles now. QUESTION: Is there any problem with just unplugging it as opposed to "doing an egr delete"? I'm in a no inspection state now, so I don't mind the CEL staying on. Subscribed!
There is no problem leaving it unplugged since it's normally closed. The issue with your CEL though, have you scanned the car to see what the issue is?
@@MBDieselFreak yes, it was: Code 2511-001 check component Y27/9 (Left Egr positioner). Positioner signals fault.
I may unplug mine as well!
@@WhitePOWERranger1 been another 25k miles, since I posted, no issues.
RESOLVED. Hi MBDieselFreak. The problem off rough idle come from the iat sensor which is located after the intercooler. I resolved mine E220 CDI by disconnecting first the iat sensor before replacing it.
Sounds like it may have had the ERG-MAF map re-programmed?
Did you end up doing the EGR emulator mod? Saw on another video you are from michigan! I am as well and love my w211 CDI with 350k on it! experiencing similar issues.
Jillian O'Connor not yet! I haven't installed it! it was actually another problem that was causing the misfiring.
look up my video on the intake port shutoff flaps!
Jillian O'Connor you're having the same problem I'm describing in this video? check out my other videos on the CDI, I've done a stupid amount of research trying to track down what's been causing this issue, and fixed other little problems along the way. ended up being intake flap shutoff valves.
btw where in Michigan are you located? im in Lansing, I don't see very many CDI drivers in the Lansing area!
Have you made a video on the intake flap valves?
Probably not, i didnt found that on his chanel
Sorry guys, the video i mentioned here, for some reason youtube removed it. i had it embedded in a forum post as well, and now its gone. i've re uploaded it, it can be found at: th-cam.com/video/8lt4IjzSYNo/w-d-xo.html
My car goes in limp mode and sounds like v8. And i have no warning lights , can it be egr ? Cause i changed it once .
After reseting car , its all normal
Just got same problem on w220 s320cdi, loss of power sometimes and then would go into limp mode with no warning lights, restart car and it’s ok
Turbo actuator!........
How do I bypass my egr on my om642 C350 CDI
Can you help? This sounds like mine///Here it is the quick story:
I am not knoledgeable enought and sorry to call it misfire for a diesel.
it is actually like a hiccup and it feels/sounds like an explosion. Thought it has something to do with the combustion. Dealer wanted to change 3 injectors for bad values but not specific codes quoting me at $2800 before tax.
Other mechanics recommendations were injectors as well. Therefore I had my Indy changing some of the injectors today with no change.
As short history car has 166k miles and this started at about 164k miles shortly after and around or at about the time of adding freezing additive for diesel fuel while a tank fill up which could be just coincidence.
Egr code has been on and off rarely every now and then for the past year...about 35k miles.
Lp fuel pump in tank replaced at about 145-150k miles. Shortly after at about 155k miles fuel filter changed.
No start up problems, no smoke like when bad injectors. No hiccups for the first 5-10 min when cold. Then thy start randomly intensifying in frequency with the warmer the engine gets, but also sound/feel of the hiccups/explosion/detonation intensify itself as well. The fee is more like a skip of something like a big heavy chain from a gear to another.
It also sounds/feel like a gun intermittently shooting one round then within a second 2-3 rounds then one more or 2 seconds another 2-3 rounds.
It gets overrided when accelerating and the feel/sound of the hiccup/explosion/detonation reduces with higher RPM to the point of when reaching anything above 1500 it seems like it’s goes away or it is not there anymore.
Could it be the High Pressure pump? Could it be my EGR stuck closed/opened influencing the intake with high temp exhaust gases recirculating since it starts to be more pronounced warming up and it is never there at cold start?
Please let me know if anyone experienced anything similar or what else you guys may think of.
you ever fixed this?
@@cali_cal Mine is a blutec....they had an emissions recall for all blutec models. My biggest issue was random hiccups but not quiet the same as misfiring quickly one after the other. It was caused by a totally clogged dpf filter. Filter eventually failed prematurely because I delayed changing the addblue tank element heater and cleaning of the filter eventually wasn't active anymore. It got to the point the hiccups were more often and at the point filter was bad enough would shut down the turbo which was fine. The so called AEM emission recall fixed it for all the blutecs including mine...keep an eye on your dpf filter. otherwise yes egr have their own other problems. Keep oil changes on your calendar and do them accordingly
Hello friend
Can you upload the video with the fix for this problem?
When is the EGR meant to be activated? Is it on/off or can it half way open by computer control?
Hi, did you solve the problem with EGR??
Could this be the same issue even with a non-diesel version of the car? My E320 isn't a diesel but I'm getting the P0400 code and there's a dip in power when coming to a stop then it goes back to normal.
Hi you found the problem?
Is it true the engine can run without swirl flaps?
Absolutely. It's much harder to remove them on the om648 than on the om642, but yes the car can run fine without them.
do you know any good egr removal mods¿
The swirl flaps/port motor hack is covered in this video from Lagitstreetcars. I'm wondering if you can cheat the harness on the EGR the same way with a resistor.

What is the problem?
hi there ..im from michigan too …..i have 2005 E320 cdi what other part did you change ?
Check k out green diesel egr delete
EGR off
turbo actuator
What about the turbo actuator ? Thanks
Hello, is there any e-mail or telephone that I can contact you? Thanks!
