Closely following this thread as I am setting in Fairbanks AK with the problem and will have to see the dodge dealer Monday morning.
Followed the first post up to page 9, and then could not get any further info. Was this thread moved to another forum?
I have the symptoms mentioned in the posts. My problem goes away after I stop for the day and then reoccurs the following day after a couple of hours driving.
What I could not determine from reading the posts is this a symptom of the turbo resonator or a temperature sensor.
Stopped at the dealers late Friday afternoon and they were pretty iffy about giving me a scheduled repair time, busy, backed up, tech's sick, etc. I am considering driving on to Denali and then Anchorage where there is another dodge dealer.
One of the posts mentioned that if they stopped for 15 minutes they could then continue on for some time. If I can not get in for repair this would be an acceptable option for me.
The company I work for has many Sprinters, 2005 & 2006, all have the resonator, and most have had this problem (and others). While watching the scan tool data stream on a road the as the specified boost and actual drift apart from the leak at the seam in the resonator as soon as the gap is 9 psi the code is set and the engine rpm limits to 2000. If you pull over and shut it down it will retain the code but resume normal operation until the 9 psi spread occurs. I have examined all of the defective resonators and they spread at the seam, especially when hot. One that is ready to fail will show signs of oil seepage at the seem, a good indicator or "time to change".

Very professional/thorough explanation of the facts leading to the failure Patster...Thank you!
Well I'm not going to "bad mouth" the Sprinter, but there are things that go wrong with them just like any vehicle, Mercedes pedigree aside.
Pay close attention to oil consumption, if you find the engine is using oil in the range of say 2 litres (quarts) per 10000 km (6000 miles) there may more than operator error when checking the oil. Mercedes has equipped these engines with 2 different types of oil dip sticks, red and yellow. If yours is red check it at operating temp after sitting for a few minutes. If it is yellow check it cold. If you already know this and the engine still uses oil there is a chance that it is being passed through the seal in the turbo, both into the intake and exhaust side. In the intake side it will foul the boosted air temp sensors, both new and old versions as well as carbon up the intake and EGR passages. In the exhaust side it can lead to fouling of the variable actuator veins in the turbine housing of the turbo. This can lead to sticking of the variable geometry veins and lower or higher than expected boost and trigger codes, or cause enough strain on the actuator servo motor that it will blow the power input fuse for the ECM.
So far we have changed the turbos on the first two vans we bought, both for sticking guide ring rollers for the variable vein mechanism in the turbo (plus passing a hideous amount of oil).
Change your transmission fluid REGULARLY, the manual says once at 140,000 km. Do it sooner say every 100,000 km or 60,000 miles for the rest of its life. The fluid is expensive but use the fluid they call for. If your van does not have an auxiliary trans cooler DO NOT add one, none are approved and if your transmission fails you are SOL as far as warranty goes. Some do have factory ones, but they (Mercedes) say it cannot be added.
The "pusher fan" in front of the A/C condenser, there may be a good chance it is wearing a hole in the condenser at the lower left (driver side) corner. Pop out the grill to check it and if it is rubbing remove the nuts from arm at the bottom and add a washer between the fan arm and bracket.
There are other problems I deal with on a regular basis but may not apply to private owners. Things getting broken such as HVAC temp controllers, door latches and hinges, interior lights, mirror switches and so on. I am a mechanic for a fleet operator and we have six Sprinters, two 2005, and four 2006. The oldest ones have 250,000 km on them now and I have become very familiar with them
in the last year and a half. If you have a specific concern that you do not want to ask here, pm me. I'm not the quickest at responding, but I will get back to you.
Thanks for the information. It will help me when I take the Sprinter into the Dodge Dealer in Anchorage AK on Thursday. I will keep you posted on the results.
Thanks again for the info. It was the turbo resonator. While it was no big deal, covered under warrany, it was a pain driving in LHM, and I had to wait around in Anchorage for a day while they had a resonator shipped in. I think I will order the one mentioned on this forum and install it when I get home.
Thanks for your post. I have a question about the A/C fan or blower. For the second time mine has stopped working on anything but the highest setting (#4). The first time I had it repaired at the dealer and he said it was a fuse up under the dash but I can not find it. Have you had this problem and do you know a reason and a cure.
djcrest;
Sounds like the blower motor resistor, easy to change. If it were the fuse it usually quite all together. I have to swing by work this morning to check on some stuff, I will get you the part number and maybe a pitcture as well.
