From wikipedia: "In 1993 Toyota Motor Corporation bought TTE which then renamed Toyota Motorsport GmbH (TMG). At this time, as a fully owned part of Toyota Motor Corporation, Toyota Motorsport were employing 300 staff from 17 nations. In 1995 TTE was famously banned for 12 months from the WRC for cheating by designing a illegal air restrictor on the ST205 that included both a bypass mechanism and spring-loaded devices to conceal it from scrutineers. In the 1996 and 1997, despite lack of works team appearance in 1996 due to the ban, TTE supported the Celica ST205 rallied by Italian HF Grifone Team, Toyota Team Sweden, Marlboro Toyota Team Belgium, and Tein Sport in the selected WRC events, before introduced the Corolla WRC in the 1997 Rally of Finland. When they returned to the WRC for 1998, they did so with a Corolla WRC driven by the crews of Carlos Sainz/Luis Moya and Didier Auriol/Denis Giraudet. They finished the season in second overall in both the Drivers' and Constructors' Championships. In 1999, however, the manufacturers championship was taken, the third in TTE's existence."
