Volkswagen Tiguan overwhelming gasoline smell and Service NOW light issue requiring towing to dealership on Volkswagen Tiguan

Some Volkswagen Tiguan owners report experiencing an overwhelming gasoline smell, often attributed to fuel leaks that can leave marks on the ground beneath the vehicle. Additionally, excessive fuel pressure may cause a gas odor by richening the air/fuel mixture, which can trigger the check engine light and result in the P0172 code; replacing the fuel pressure regulator is typically the recommended solution. Other owners note that a loose, damaged, or missing gas cap can also contribute to the smell, particularly when idling with the windows down. Furthermore, some Tiguan owners report issues indicated by the "Service NOW" light, which may signal problems with the throttle system, including engine stalling and the illumination of the Electronic Power Control (EPC) warning light. It is essential for owners to address these gasoline smell concerns promptly due to safety risks and potential engine damage, and towing the vehicle to a dealership for professional inspection and repair is advisable.
