Engine light problem and error 1D2404 on BMW 3

Hi everyone, I own a 2014 BMW 3 Series with a gasoline engine and 140,000 km. Recently, the check engine light (MIL) and the transmission light came on. I found error 1D2404 which indicates 'disconnected map thermostat'. Has anyone had similar experiences or knows how to solve this problem? Thanks in advance for any advice!

Start by checking the wiring and connectors to the MAP thermostat for any signs of damage or disconnection. Ensure they are securely connected and free of corrosion. If the issue persists, it might be necessary to replace the thermostat. Let us know how it goes or if you have further questions!

Where is the map thermostat located?

The MAP thermostat is typically located near the engine, often integrated with the engine's cooling system. In your BMW, it should be close to the intake manifold or the cylinder head. Check your vehicle's manual for the exact location. Once you find it, inspect the wiring and connectors for any issues. Let me know if you need more help!
