“I purchased my van Feb 5, 2021 with 8 miles on it. By April, it was hesitating intermittently at low speeds. It got progressively worse. MB of Athens could not diagnose it in 2 visits in May and June of 2021. By August, the Sprinter service manager at RBM of Atlanta, Charles told me on the phone that he was sure it was the EGR valve and none were available. ETA of a valve was Nov, 2021. The date then moved to Jan, 2022. It is April and there are no EGR valves in the world to be put on my van. The hesitation has progressed to higher speeds. …”

“There is a problem with the engine control parameters which occurs at higher altitudes. The vehicle will not produce adequate power. This is not simply normal power loss related to density altitude. This is a malfuntion where the vehicle does not respond to the throttle, and produces only about 2psi of turbo boost even upon extended application of full throttle. This problem occurs only on sprinter 4x4 models with the OM642 diesel motor. I experienced this problem for the first time yesterday when pulling onto a 2 lane highway at 7,000 feet in the sierra nevada. …”
