It's 2013 - any updates on IMS issues or cost of engines?

[SRW]

Guys, I am anew 986 owner and after a trip to the Porsche dealer to treat my new baby to a major service lost all power and had to pull over. Batty is good, tried turning engine over twice at the side of the road but it felt like maybe the serpentine belt had gone ( although it is less than 2000miles old due to me replacing the water pump as a safety measure when purchased). Anyhow I had it towed to the Porsche centre and they called me back stating it could be the IMS. The timing seemed to be slightly off. I'm gutted and to say the least from what I can find on the forums it will not be honoured by porsche as its a 2001 with 70k miles. Lots of comprehensive history and even a new clutch about 15k miles ago. Is there any advice u guys could give to protect me from being " had over" by the dealer when they come back to me with a diagnosis? I have just given them permission to drop the gearbox and have aloof inside the engine which is gonna cost me £ 800 upwards.

This is not the entry into parker ownership I was expected. Thanks in advance chaps.
