I was reading an article about the Toyota throttle issue in the USA, the article states:
Toyota will also add a so-called smart pedal, software that cuts engine power any time both the accelerator pedal and brake pedal are depressed at the same time.
Such software has already been adopted as a safety feature by a number of automakers, including Volkswagen, Audi, Porsche, BMW, Nissan and Chrysler, the companies said.
Don't know for sure but the Tiguan probably has this system...
