Since 1996 BMW introduced 105C MAP DME controlled thermostat for V8 and 97C for Inline 6 cylinders, which can be controlled by DME when needed. Obviously nothing wrong with thermostat quality, in fact its a very good quality part made by BEHR. Why I called it BMW THERMOSTAT PROBLEM? What is wrong with that simple part in BMW? It looks like a well made thermostat and lasts for a while.


THIS POST AFFECTS ABSOLUTELY ALL BMW GASOLINE ENGINES AFTER 1995! M54, M62, M62TU, N62, N63, N52, N47, N63TU AND OTHERS, OR WHY IT IS A VERY GOOD IDEA TO LOWER RUNNING TEMPS!
