Oliver Jarvis lost control of his No. 8 Audi R18 in Turn 12, just moments after pitting for what appeared to be slick-intermediate tires.
The spin sent Jarvis hard into the barriers with heavy right-side damage but the Englishman managed to limp the car back to the pits, and into the garage for repairs.
It came as a bitter blow to Audi's hopes, and handing Porsche a 1-2 in the race, headed by the No. 1 Porsche 919 Hybrid of Brendon Hartley, who took on wet tires in the most recent stop.
The No. 6 Toyota of Stephane Sarrazin has been elevated to third, as a result of the Audi's misfortunes.

The leading pair of Hartley and Duval are at the wheels of the two most competitive cars so far, but the entire LMP1 class has seen some close racing so far.
