I feel for you!
My '01 had lost it's first heart in the dealership (thank g-d). At 75kms, Massive Engine failure.
Melbourne Porsche replaced the engine (saw it come out the crate!) and delivered my new car with a new thumper!
At the time, I asked if it was common and they said "It has happened before"????
Give Porsche a shove, they may fold? Their reputation (Germans) means alot to them if you get my drift.
Good Luck!!!!!
