Problem with code 4030 and engine temperature on BMW 1
(Translated from Spanish)
Summary of the thread
A 2007 BMW 1 is experiencing delayed engine temperature rise and error code 4030. The problem may be due to a stuck-open thermostat or a faulty temperature sensor for the particulate filter, which shows incorrect readings. Suggested solutions include checking and possibly replacing the thermostat and inspecting the particulate filter's temperature sensor and its connections for damage or corrosion.

Start by checking the thermostat, as it might be stuck open, causing the engine to take longer to reach operating temperature. If the thermostat is faulty, replacing it should resolve the issue. Let us know how it goes or if you have any further questions!
The engine picks up 90 degrees, it is the particulate filter that does not pick up enough temperature marks -50 degrees with the engine cold.

Check the temperature sensor for the particulate filter. A faulty sensor could be giving incorrect readings, affecting the filter's performance. Inspect the wiring and connections for any damage or corrosion. If the sensor is faulty, replacing it should help. Let us know if this resolves the issue or if you need further assistance.
