Having been forced into an engine change following the first session, Jason Plato was tenth quickest having spent much of the session going in and out of the pits, although there were a number of other drivers to hit issues during the final practice prior to qualifying.
Dave Pinkney suffered gearbox failure on the Cooper Straight which has left his team with work to do ahead of qualifying, while Mat Jackson suffered an engine sensor fault which forced him to park up on the side of the circuit.
Fellow BMW driver Andy Neate meanwhile went off into the gravel exiting the final corner, bringing out the red flag as his car was recovered.
