What should the idle speed be on a Volkswagon?
Prepare a basic setting of the engine control unit (adjusting it to the throttle valve control unit). After ignition the engine only runs with 500 rpm and has no response from the accelerator. As the start was too short and the engine was too low, the idle speed stays at around 500 rpm (approx. 50°C coolant temperature).
Why is the idle speed on my golf so low?
Cause: The Multipoint engine in the Golf has been made more protective to the environment by keeping the idle speed very low (600-700 rpm). Therefore the idle speed is more noticeable in comparison to the last model. Fixing must be avoided. The idle speed cannot run smoothly and cannot be changed. Discussion on this is on going.

Who is the inventor of idle speed control?
A highly simplified two-input (idle bypass valve opening and spark advance), two-output (engine speed and intake manifold pressure) idle speed control model for IC engines was developed by Yurkovich and Simpson (1997) and used in this work.
Why is the idle speed of my car so high?
