SYMPTOMS OF FAILURE:
Rough idle, loss of power, engine management light on, failed emissions test, delayed acceleration.
Fault codes P2006, low engine torque, lever broken or damaged upon physical inspection...
THE ERROR:
The intake manifold lever wears out and gets damaged, causing vehicle malfunctions.
Mercedes OM642 V6 vehicles have intake manifold problems, the swirl flaps in this manifold are controlled by an external operating lever. It is made of poor quality plastic that wears out prematurely.
Swirl flaps are designed to assist with low-end torque and fuel economy. Over time, the plastic wears out at the connection points to the manifold, creating an oval shape that eventually lifts the rod, leading to breakages causing the malfunctions noted above.
Physical inspection of the intake manifold will quite often show the rod broken in half. The wear is due to the plastic being the wrong specification for the task; it cannot cope with the heat and constant mechanical movement.
These intake manifolds can also become heavily clogged with carbon deposits, which can make it difficult for the swirl flaps to move, which in turn puts more stress on the engine and the lever.
You can usually identify this problem by removing the engine cover and inspecting the intake manifold; often the lever is broken, or you can test for excessive play in the rod linkage.
