Any mechanic that tells you to just ignore the temp gauge is not only a bad mechanic, but he is probably also not familiar with how to bleed a BMW cooling system. It needs to be bled propperly. The links above will explain the process. I would not let that mechanic work on your BMW any more.
It is possible that there is a thermostat problem, but an air bubble is a more likely scenario. What brand of thermostat is it?
It's all OEM, but the cluster has been replaced before...It has that dot before the miles that says its been replaced. My mechanic is an ex-BMW Of San Diego Mechanic/Tech, he says my clusters just bad. I'll bleed tomorrow for sure.
