Set multimeter to resistance. Disconnect the negative battery cable (safety). At the DME (usually in the passenger side e-box under the hood), locate the pin for thermostat control (check wiring diagram for your specific engine). Measure from the harness connector pin at the thermostat to the DME pin – should be < 2 ohms. High resistance means a broken or corroded wire.
What I’ve tried:
: There are comprehensive manuals and databases available for BMW technicians that provide detailed explanations of error codes, possible causes, and diagnostic procedures.
Have a different BMW code? Check our other guides for codes like 030830, 030820, or P0128. Drive safely.
