WTF? Three thermostats and...

Okay, so my CLS63 has gotten some miles on her and I got a P0128 code CEL. I know this is the thermostat deal, engine coolant temp too low. My indie changed it, Bremen Autowerks. So after some miles, the CEL again, same code, cleared the code, it came back. Bremen changed the thermostat again, as it was under warranty of course, they were thinking possible faulty thermostat.

Fast forward to today, the damn CEL is on again with the same P0128 code! What is the problem? Someone give me some insight, I started thinking possible coolant temp sensor? What?

Will do. These guys have many years of experience at Bremen, all they do is work on MB's and BMW's. Strange, this would happen on two thermostats. I will get a part no, and post back.
