E320 CDI Power Loss and Limp Home Mode

This is info from another website that could be useful:
"I have a 2005 CDI just 1 year old, 21K miles on it. I've had similar issues. After about 6 months the car would accasionally cough and stall, or cough then run.......coasting off a highway ramp, asked for power, got none. Acceleration was limited and engine noise was distinctly louder...... MB found that stopping and restarting it restored power. They told me this was the computer putting the car in the Limp Home Mode. This code occurs when the computer thinks that continued use might damage the engine, so it restricts output to half throttle and transmission to lower gears.

AFTER THE EGR VALVE WAS REPLACED, CAR IS BACK TO DELIGHTFUL SELF....."

It looks like they are having some EGR problems. I am putting a note in my Operating Manual regarding the loss of power problem.

holy smokes, that sounds exactly what i've been experiencing with the sputtering and hesitation. Sorry for the basic question but what exactly is an EGR valve?

Kort have you had any issues after this? Did the CEL come on? Did they also take a look at the transmission. Just trying cover all of the possible diagnoses. Ontop of the diesel smell and leaks which have now been fixed, the ongoing hesitation continues especially after driving at highway speeds and taking my footy off the gas pedal (ie. exiting the ramp) the car begins to hesitate and feels as though if i don't give it some throttle it will stall. Frustrating but after all of this, i still love the CDI. Go figure

Nothing came on, the car just went into limp mode, took it to the dealer and they replaced the egr valve, no problems since then and that was 30k miles ago

Exhaust gas recirculation valve.... does exactly what it says, and keeps the engine warmer inside, and aids combustion.

It actually feeds some exhaust gas back into the intake manifold to reduce ignition temperatures and that will reduce NOX.

The valve should only open at part throttle. At idle or with a closed throttle, the valve should close to prevent exhaust gasses from getting to the intake. If the valve fails to close you can have a rough idle or similar problems. With modern engines, electronics and sensors are used rather than the old vacuum method so there could be something else besides the EGR Valve at fault.

EGR is designed for one purpose, to reduce emissions. Otherwise, it woudn't be there.

2006 E320 CDI
W211 CDI EGR Replcement

I wanted to thank all who contribute to this forum, I have learned alot, and saved countless $$ from the info on these forums. My '06 CDI has been misbehaving, and finally pinned it down to the EGR. The P0404 code led me to the EGR, I took the EGR apart, and cleaned the soot under the plastic cam cover, still goes into limp mode. Aftrer removing the EGR again I was able to determine that the tempered steel return spring was broken and the cam would not return to the home position. If you follow other threads, there's no way to rebuild these due to the welded cam. A little patience and a lot of research yielded the following: Mercedes offers a rebuilt Wahler EGR also if you buy one from the dealer, there is a core charge. You can pick one up for under $400 delivered, then return the core. I hope this helps someone , as this forum has inspired and helped me.......

I will update when I recieve the parts, I expect final cost to be around $370, From an online parts site, after shipping back the core. I haven't seen anything cheaper.
With the $$ I save I will replace the flexible disc on the driveshaft, then onto the upgrading the calipers and rotors......

The turbo has an actuator in it that sticks because of carbon in the vanes. If you take the air filter off start the engine and run it at about 2000 rpm spray water in the intake about half a bottle of distilled water in a spray bottle , take your time and shoot the water in slowly. This should free up the vanes in the vnt turbo. Once the carbon is freed up in the turbo it will all go out the exhaust. Worked for me after getting all the BS from the dealer. I actually used my windshield washer reservoir and routed the hose into the plenum after the Maf sensor. While I drove I squirted water from the washer button into the engine. Not a sniff of limp home mode now for over a month. I drive it every day and lots of miles.------now working for over two years. cost me 5 dollars to fix

E320 CDI Power Loss and Limp Home Mode

Well finally i got the credit for the core on my EGR from parts.com, so far no issues with limp mode or CEL. In my case I know the EGR was the issue, I still get a little black smoke every now and then, I think something else is amiss, but I am happy with it. after shipping and returns, the EGR was around $375, was the best deal I could get. I took photos, will post when I find camera......
Anybody know where I can get a decent tune for low $$ I'd like to go with GDE but I have kids to put through college.
