Unfortunately, they have conceded that the work does take more than 1.9 hours and are amending the dealers work sheets on this recall appropriately with new work timings, so if you haven't had your pedal box replaced yet, then expect your car to be in for a day now for the work.
VW accept that the Pedal Clips and parts have not been available to complete the work promptly and are ensuring dealers they can call their dealer network parts ordering service to get parts shipped more quickly as many parts are on back order
