Throttle Valve Removal

Whilst petrol vehicles require a throttle valve to operate correctly, this is not the case with Diesel vehicles. Diesel engine speed is regulated by fuel injection and not airflow. The purpose of a throttle valve on a diesel vehicle is to reduce oxygen in the cylinder for emissions purposes.

Modern electronic throttle valves do fail, and are costly to replace. MB tuning can provide a software patch to allow the majority of diesel engine control units to work without a throttle valve installed.
