Death
He qualified 6th during his first practice session for the Grote Prijs van Zandvoort, the Dutch round of the 1980 European F2 Championship. Towards the end of the second practice session, he had a minor crash in the chicane and went back to the pits. Even though the mechanics repaired the broken suspension and changed the nose of the car, he could not test his Tiga F280 BMW until the warm-up session on Sunday 20 July 1980. During his first two laps, he circulated slowly around the track to control the suspension. He took his 3rd lap at full speed. On the following lap, he went off the track, on the left side at the Scheivlak bend, at about 200 km/h. He crashed head-on into the guardrail and hit his head on the fence-pole. The first driver to arrive at his accident was Beppe Gabbiani, who found Bürger's helmet broken in two. In a few minutes he was taken by ambulance to the EG Elizabeth Hospital of Haarlem. One hour later, he was transferred to the intensive care unit of the Wilhelmina Hospital in Amsterdam, where he succumbed to his head injuries two days later.
