I don't believe that this will change unless someone legally forces Porsche to pay up or change the engine design.
I agree with the point above; Porsche knows about the issue and has taken the
"patch" approach rather than the expensive redesign approach.
It has been 9 years now, so lets be clear, the boys in Germany have found there "solution" and unless the marketplace or the courts tell them otherwise, they are sticking to it.
Cayeene seal anyone?
