You've probably missed it in my post. DME controlled thermostat is being replaced (just as in my 540) with the 95 C conventional thermostat without the DME electrical connector (as found in early 840ci with M62 engine).

This thermostat is direct fit to WP opening other than having old style hose type fitting which is easily remedied.

DME wiring will have proper resistor which has been proven to keep it from throwing check engine light or the code.
