Volkswagen engineers suspected the cause of the driveshaft problems were related to a new seal that was tested successfully before the penultimate round of the season but didn’t work in the unique conditions that have to be overcome at Rally GB.

Team boss Sven Smeets confirmed an investigation is underway: “The parts are on the way to Hannover. We have an idea but we’re not sure yet. We have to get to the bottom of this before Australia,” he said.
