2004 vw Touareg v8. These vehicles exhibits frequent but inconsistent delay in throttle response. This issue arises most often in heavy traffic when the driver comes to a rolling stop. When shifting inputs from the brake to the throttle the vehicle will frequently exhibit a 1-2 second delay before there is any response from the engine. This has two dangerous consequences. First, the driver may increase the throttle pressure waiting for a response, then getting more then expected acceleration when the engine finally responds. Second, the driver could be left sitting in an oncoming lane waiting for the engine to respond and take the vehicle safely across the intersection. I have reported this to two different vw dealers, one of which turned the complaint to vw. There has been no action taken, or further response from vw.
