Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely parked.
Disconnect the high-voltage battery by following the manufacturer's safety procedures.

2. Inspect Drive Unit

Remove the undercarriage cover using a socket set.
Visually inspect the drive unit for any signs of fluid leaks or physical damage.
Listen for any abnormal sounds when the drive unit is powered on (with vehicle in park).

3. Check Bearings and Components

Inspect the drive unit bearings for wear; if they are noisy, they may need replacement.
Check the alignment of the drive unit and ensure all bolts are torqued to specifications (refer to service manual for torque values).

4. Test Drive Unit

If no physical issues are found, perform a test drive to confirm the noise persists.
While driving, toggle between different driving modes (Standard, Sport) to see if the noise changes.

5. Reassemble and Finalize

Reinstall the undercarriage cover using the socket set.
Reconnect the high-voltage battery.
Ensure all tools are removed from the work area.
