Took my MS to the service center to fix the creaking headliner. As I drove it away there was no more creak for about ten minutes. Then it slowly started coming back. It’s not as bad as it was but still annoying. My next step is to pull the headliner myself and see what I can do. Service center adviser said to take off visor clips first but be careful b/c they break easy. I’m probably going to buy a fiber optic video camera from harbor freight $150 to look up under the headliner after pulling down the front edge. Hopefully will get around to doing it in the next month. Will post when completed. The service center visit wasn’t all in vain as they did get rid of the yellow band around the MCU screen.
