This is the reason why I continue to push on with this information, these AOS parts should be tested every time the car goes into a Porsche Dealer, or Porsche Specialist.
This is a really important engine part, that can cause a lot of trouble.
Couldn’t agree more Dave. An AOS condition check every 2-years would go a long way to nipping in the bud any failures before they become catastrophic, especially on cars fitted with a GPF.
