My contract was with Warranty Direct
The reason why they gave me so much trouble was mainly because they didn't want to pay and looked for any excuse in the book

So their list was like this:
* Well the engine is still running, let's wait until it dies
* If you want us to pay YOU have to pay first for dismantling the engine so that we can have a look
* Neglected maintenance (which was bogus, I had records for every service and it was all done at the same shop, so that didn't fly)
* and the list goes on and on
So generally if you give them ANY excuse to not pay they will gladly go for it, so make sure that you do have your maintenance done when Porsche wants you to and that you have all records and receipts
