your temp in the video posted is ALWAYS in blue. And the vid is about 3 minutes long. My M54b30 engine has the temp dial a looong time in the middle after driving that long under those ambient temps.
There might be a combination of things: a bad temp sensor, and I think it's the dual temp sensor located on the engine - in the back, and after your long post with the scan - something fishy with the O2 sensors. But this might be due to a hot engine, which reports cold temps.
