Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

This is more of an update on the coolant issue. To recap, drained the system, flushed with distilled water and finally refilled. Had problems with that, even bought a vacuum pump to make it happen. Finally discovered the problem. Reservoir tank leaks. Very tiny drip, but enough to mess it up. Cannot really see from where (not hoses). Will remove it, see if repairable or buy a new one. It's always the little things that mess up a project.
Whatever you do, buy an OE tank. It's too much hassle and work to put an aftermarket unit in there.
The coolant tanks on the 986 are prone to breaking so glad you tracked down your culprit. Porsche has redesigned this part several times, but they still have their issues.
