What are the reasons for high idle speed when the Volkswagen VR6 engine is warm?

[LaLeilani]

Volkswagen VR6 high idle speed when warm may be due to the idle contact point being disconnected. The ECU then determines that the engine is under partial load, but the engine is actually operating under idle conditions with less air intake, resulting in an overly rich mixture and increased RPM. Advantages of the Volkswagen VR6 engine: The 15-degree angle on the VR6 offers the greatest benefit of making the engine more compact. The 6-cylinder machine has the size of a 4-cylinder, reducing weight, which decreases the likelihood of understeer during cornering and improves handling responsiveness. The VR6's six cylinders are staggered in arrangement, appearing more like a 4-cylinder engine from above, allowing for easier intake and exhaust layout, which is beneficial for optimizing space in the engine compartment. Models equipped with the Volkswagen VR6: Volkswagen models that use the VR6 engine include the CC, imported Passat R36, imported Passat Wagon R36, and Golf R32. A more familiar model equipped with the VR6 engine is the Passat Wagon R36, which is a high-performance station wagon.
