Fritz, it was genuine but nothing indicates a final solution other than they believe the loosening bolts are the problem. 

Something Porsche really needs to understand and learn. Dealers rarely provide up to date information. More often than not, the internet is the place to get information and we pass that on to the dealer. I recall one dealer lamenting that often he is the last to know what is going on. It's a vicious circle. Dealer tells you to check with PCNA and PCNA tells you to check with the dealer.

The dealer is the last place I would go to get information.

Last night I was prepared to end this saga but just tell my dealer to return my deposit. But today I read an article from Pistonheads which had interviewed the CEO of McLaren. In it he states that the GT3 to a tour de force and a technological marvel. His high praise is worth noting since he acknowledges his models are designed to compete against Porsche's and not artistic cars like Ferrari. As a result, I am waiting to hear if I will see my car anytime soon.
