Solution

1. Preparation

Gather all necessary tools and parts. Ensure you have a replacement key fob battery if needed.
Safety Warning: Ensure the vehicle is in a safe, well-ventilated area before working on it.

2. Key Fob Battery Replacement

Open the key fob using a small flathead screwdriver.
Remove the old battery carefully.
Insert the new battery (typically a CR2032) ensuring the positive side faces up.
Reassemble the key fob and test the remote start function.

3. Error Code Diagnosis

Connect an OBD-II scanner to the vehicle's diagnostic port.
Retrieve any error codes related to the starting system.
Document the codes for further investigation.

4. Check Vehicle Settings

Start the vehicle and navigate to the iDrive system.
Select 'Settings' and then 'Remote Start'.
Ensure that the remote start feature is enabled.
Save any changes before exiting the menu.

5. Battery Voltage Check

Use a multimeter to measure the vehicle battery voltage.
A healthy battery should read above 12.6 volts when the engine is off.
If voltage is low, consider charging or replacing the battery.
