Car started misfiring then refused to start. The cam gears were damaged and caused the cam to skip a few teeth and gave a cam sensor fault. Engineer replacing valves and valves guides. Cost of repairs was R33500. Luckily had an extended warranty. The presafe system was giving an error so they replaced the module and also the driver seat belt clip and the problem was solved.
