Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Replace Air Filter

Locate the air intake housing; remove the screws or clips securing it.
Carefully remove the old air filter and inspect for dirt or obstructions.
Install a new air filter that meets BMW specifications.
Reassemble the intake housing and secure all fasteners.

3. Inspect Fuel System

Access the fuel pump and check the fuel pressure using a fuel pressure gauge.
If pressure is below specifications, replace the fuel filter and inspect the fuel lines for blockages.
Test the fuel injectors for proper spray patterns; replace any faulty injectors.

4. Throttle Body Cleaning

Remove the intake duct leading to the throttle body.
Use a throttle body cleaner to spray onto a clean cloth and gently wipe the throttle plate and housing.
Reassemble the intake duct securely.

5. Check Transmission Fluid

Locate the transmission dipstick; remove it and check fluid levels.
If low, add the appropriate transmission fluid as specified in the owner’s manual.
Inspect for any leaks around the transmission pan and seals.
