Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, basic hand tools (screwdrivers, socket set).
Ensure the vehicle is parked in a safe, well-ventilated area.
Disconnect the battery before starting any electrical work.

2. Check Key Fob Battery

Remove the key fob cover using a small screwdriver to access the battery.
Replace the battery with a new one (typically CR2032).
Reassemble the key fob and test remote start functionality.

3. Inspect Vehicle Battery

Open the hood and check the vehicle’s battery terminals for corrosion or loose connections.
Use a multimeter to check the battery voltage; it should be around 12.6 volts or higher.
If the voltage is low, charge the battery or replace it if necessary.

4. Scan for Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Retrieve any stored codes and note them for further analysis.
Clear the codes and attempt to perform remote start again to see if new codes appear.

5. Verify Remote Start Settings

Turn on the ignition (without starting the engine) and navigate to the vehicle settings using the iDrive system.
Look for remote start settings and ensure the feature is activated.
If necessary, consult the owner’s manual for specific instructions on enabling remote start.

6. Check Fuses

Locate the fuse box (usually under the dashboard or in the engine bay) and find the fuse labeled for remote start or engine management.
Use a fuse puller to check if the fuse is blown; replace it if necessary with one of the same amperage.
