Volkswagen Sharan Flywheel / Clutch failure?

Hi there, we have a 2006 Volkswagen Sharan, and last night it developed a noise while driving. We continued to drive but after couple of miles at most, someone has flashed us from behind. We pulled over and smoke came from under the bonnet and the engine was on fire. Not a bad fire, but still we needed 2 litters of water to put the fire out. We started the engine and it seems ok, so we drove on, but then we have seen a RAC patrol and pulled over to speak to the guy. He inspected the engine compartment and we could see small shredded metal all over the lower part of the engine. He said that the flywheel and the clutch might be gone, and although the car was still drivable, he has towed us home. On researching the issue on the internet, we see that Sharan has recalled many cars manufactured in 2006, but our car is not listed on the ones that are due back for repairs, yet the issue seems to be the same. Can anyone help?
