Just an update:
I checked the vacuum system for anything that doesn't work, and noticed that even with the engine running the fuel filler actuator did not lock the fuel lid so I disconnected the central locking by removing the yellow check valve from the 4-way fitting, and now it shuts off properly. At least I know it's in the central locking system now...
When I lock the car though, only the fuel filler actuator doesn't lock the lid. The rest does lock, albeit slowly, but they do. Does that confirm that the fuel filler actuator is the culprit? When I tried to bypass it, I felt some moisture on the two 3-way fittings. Does that confirm that either the fittings have gone bad or the actuator itself needs replacement?
Thanks for your insight. I hope to get the system up and locking properly again
at least I don't have to humiliate myself each time I shut her off.
