Axel,
Can you precisely describe at what speed, engine load, road profile and into which gear the truck is when you say it slightly 'balks'?
Does this happen after a stable cruise, after a slight deceleration or during a normal acceleration at the very beginning or after a few seconds?
Has your engine reached normal running temperature when this happens?

Winter missed the part about the catalytic convertor. Possible but no code. Was a question I asked the dealer. I need to track the codes before I erase them.

The p0401 and p0101 codes can be recieved if you have a bad catalytic converter or any other restrictions in your exhaust system . Also you need to clear your codes to properly work on correcting your problems as per the manual .
Thanks to Caribou1 you have very easy access to a manual if you will go to his message #10586 and click on address he provided . Pages131 132 133 on code # P0401 as a starter .

Thanks. I do have a service and parts manual that I orderd on Ebay and the one from Caribou1 is similar. I have been driving the vehicle for the last couple days and resetting the light after reading the code. My plan is to change the Boost Vacuum Sensor Filter and the Crankcase Pressure Control Valve. Once that is done I plan to clean the CAC lines to the EGR and make sure all lines are tight when I put them back on. I will check the vacuum lines and the gate valve operation. I also plan to clean the EGR pipe the runs to the Air Intake elbow. The pipe looks like it is two pieces with the other end hooking to the turbo and up and behind the exhaust pipe. Looks like a really mother to get out. Any suggestions here would be welcome. That said I am going to try and make a pipe cleaner with springs that are flexible and and try to scrape the inside of the pipe to loosen up the carbon and remove any possible blockage. This pipe runs behind the motor in front of the firewall. Before I clean the exhaust piping I plan to run the truck to see if I get any more codes. If not I plan to try to keep snorting the engine to keep it clean.

Axel,
I re-read your initial entry and saw that you are using Mobil 1 0W-40. I think that using something different would be advisable. The dealer I use has gone away from using the 0W-40 as there have been several CRD owners who are having oil consumption issues as well as carbon accumulation issues. Once these owners moved to a different oils, both problems were significantly reduced.
Some CRD owners are using Shell Rotella 5W-40, while others are using Amsoil products. I am using Red Line 5W-40.
I really do not know what to recommend to you.

5W-40, what does the engine manufacturer say. Interesting.
That said thanks for all your andd Carabou1's support. Yesterday I removed the EGR lines. It was actually easier that I thought. Getting them back one was another story but I got it done. While a little sooty they as well as the CAC lines where not obstructed so the ngine was not coked as they dealer said.
I also changed the Crankcase vent valve and the Vacuum sensor filter as discussed. While working I removed the Electronic throttle control to clean the inlet throat (makeup air) of the EGR line coming to the throttle contol. I found there was missing o-ring seal missing between the air intact elbow and the control. I also noticed crud build up on the engine mount which seemed strange. I obtained a new seal and installed. That may have been giving me the insufficent air flow (401) codes I was getting since it was leaking. The dealer however will not admit it even though I took pictures. I test drove the vehicle and it was shocking the power I got. I am continiung to monitoring now to see what comes. Again thanks.

OK folks took it for a test drive. First drive was fine, great power and acceleration. No codes. Took it out this morning, same performance, got about 10 miles and the light comes on. Stopped and checked code. Got three codes, first was 299, second was 401 and third was 299 but it was pending. Did review and took information down. RPM 1906, Load 67.4% Air Flow 56.22 GR/Sec, Map 137 KPA, Coolant Temp 158, Air Intake Temp 109,Speed 23 MPH. I reset the light. Drove the vehicle approx 35 miles and stopped to do some shopping and for lunch. Moved the vehicle from one end of the parking lot to another turning into the parking spot the light comes on again. the car was driven highway speed and I even snorted it to blow any carbon. Got some but not a lot of black smoke and again performance was great. Car really took off. Got lots of power, shifts well. Really moves out. Got three codes again. This time it was 401, second was 299 and third was pending 401 pending. Stats were RPM 729, Load 36%, Air flow 15.33 GR/Sec, Map 92, Coolant Temp 154, Air Intake Temp 68, Speed 1 MPH. Diagnostics tell me to go to EGR valve and then exhaust system for restriction, (Catalytic Convertor). I looked at Turbo issues. When I checked the CAC I checked the turbo rotation and the gate value and they seem fine visually. I did not dignostically check them because I don't have the tools. Any thoughts on this one. My Dealer is looking into this and will be getting back to me. I would like to talk with him intelligently on this issue. Anything would be helpful.

I was fighting the same codes recently.
What I did was clean out the boost sensor. It didn't look bad as I have the EGR disabled, just a little oily. I hosed it down with carb cleaner and it hasn't acted up since.
No performance issues before or after.

Axel,
If you look in the owner's manual, you will find that 5W-40 is an acceptable alternative to the 0W-40.
The RedLine oil I am using is a "CJ" rated oil designed for the new diesels with the particulate filters. The 0W-40 is a "CF" rated oil. The common thread between these two ratings is that they are both low ash. Redline costs about $9.95/quart plus shipping from the manufacturer. I have another source that costs less and if you purchase $100 or more, and shipping is free.
I read your test results and it sounds promising. Please keep us informed as things move forward.

I am curious about the comments on the type of Oil to use in my CRD. I have a 2006 CRD with 83k miles on it. After a few Dealer Oil Changes at $115.00 each with the 0W-40 oil specified in the manual, I started doing my own. I could not find 0W-40 so I am using Mobil 1 5W-40 Turbo Diesel Blend. The manual says 5W-40 is OK as a second choice. I use a fuel additive and I regularly "Blow the Soot" out of my CRD by running it hard from a slow roll up to about 75 MPH. I have had not EGR issues that I know of and my Turbo Boost Pressure Sensor has only been clogged a few times in 3 1/2 years and 83k miles. Should I switch to another oil?
