Removing Flap Valves
Sealing Shaft Holes
Although not required, some will remove the manifolds to remove all swirl valve components. After flap removal, tap the shaft to accept a bolt. In this case we tapped m10x1.5 and inserted flange bolts to seal everything off. No welding, no sealant, no fuss..:)
Old Style Servo
This is an early model servo arm. The top of the servo arm has a pronounced portion that sticks up rather than the new style which is flat. We have servo mounts that can accommodate re-using this servo when buying a Gold Kit just let us know. When purchasing a Platinum Kit we upgrade to include the new flat servo style and new Bosch style sensors. (upgrading is suggested to avoid positional errors)
Drill Template
The Drill Template will assist in marking and drilling the mounting holes for the servo assembly. Choose a flat surface, away from heat, moisture, loose wiring, and anything else that could interfere with the servo operation. 1/4″ self tapping screws or nut/bolt work well for mounting. ( supplied with kit )
Why do I need Benzservofix??
When you build a tough 3.0l diesel engine that can effectively get 500k or more miles is very good. Then to include fragile plastic parts that always fail, is very bad.. Removing these components will increase the reliability of your engine. Eliminating one of the leading causes of engine related service.
Electrical Harness
Using original Mercedes weather pack connectors on the wire extensions, ensures years of trouble free operation. Sometimes the old connectors can be stubborn to separate. This type of connector uses a “grey” locking tab to prevent inadvertent disconnects. Make sure to unlock the grey tab before disconnecting all harnesses. Also avoid pulling on the wire on the harness directly. Grip and apply pressure to the plastic connectors only.

Test for function
Install the three wire extensions. Test for function. The servo will always cycle several times after the key is turned off, as well as movements based on throttle position ( after closed loop status )this is normal. Depending on where the servo is mounted, it is very likely you will hear the servo operate from inside the interior, during shutdown. This is also normal as the sound/vibration is now transmitted by the chassis.
