Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Gather necessary tools: clean rag, funnel, and transmission fluid.
Wear safety gloves and goggles for protection.

2. Check Fluid Level

Locate the dipstick or fill plug: For the G30/G31 series, it is typically found on the rear of the engine bay or on the side of the transmission.
Remove dipstick/fill plug:
- If it’s a dipstick, pull it out carefully; if it’s a fill plug, use the appropriate socket or wrench.
Wipe and Reinsert:
- Clean the dipstick with a clean rag, reinsert it fully, and then remove it again to check the fluid level.
Determine fluid level:
- The fluid level should be within the designated markers (usually 'Hot' and 'Cold'). If low, proceed to add fluid.
Add transmission fluid if necessary:
- Use a funnel to add the correct type of BMW-approved transmission fluid (refer to owner's manual for specifications).
- Add fluid gradually and check the level until it reaches the required mark.

3. Replace Dipstick/Filling Plug

Reinsert the dipstick or fill plug securely to prevent leaks.
