2006 Volkswagen Touareg P0691 Fault Code: Fan Control Circuit Low - Diagnosis and Solutions
My 2006 3.2L Volkswagen Touareg is displaying fault code P0691, indicating a 'Fan Control Circuit Low' issue. I've already checked the fuse and relay, both of which are functioning properly. The vehicle heats up quickly, and when I turn off the engine, the cooling fan remains on for several minutes after shutdown. I initially suspected either a faulty water pump or thermostat, but I'm seeking expert advice on potential root causes and troubleshooting steps for this specific P0691 code in a 2006 Touareg.
