Dieter has participated in 53 24-Hour Races. Starting with motorboats in the 1950s, he became part of the Formula 2 team of Bayerische Motoren Werke which intended to take part in the 1969 German Grand Prix. Teammate Gerhard Mitter was killed at the Nürburgring while practising with the Bayerische Motoren Werke 269, though.
As a suspension or steering failure was suspected, the Bayerische Motoren Werke team with Quester and Hubert Hahne withdrew from the race, as did Mitter"s teammate at Porsche, Hans Herrmann.
Quester participated in his home 1974 Austrian Grand Prix on August 18, 1974. Quester then focused again on European Touring Carolina Championship to drive a Bayerische Motoren Werke 3.0 Computer Science Laboratory for Schnitzer Motorsport.
Later racing in the Diploma in Tropical Medicine, he once slid on the roof of his Bayerische Motoren Werke M3 over the start/finish line of the AVUS for a 3rd place. His career is still active at age 70, sponsored by Red Bulletin.
Stuck and Quester returned in the 24 Hours Nürburgring, but their Bayerische Motoren Werke was destroyed in a crash at night that involved an oil spill and seven cars.
