Inspect Turbocharger:
- Remove any covers obstructing access to the turbo.
- Visually examine the turbo for signs of oil leaks or damage.
Repair or Replace Turbocharger Components:
- If leaks are found, tighten or replace any loose or damaged hoses.
- If the turbocharger itself is defective, remove it:
  1. Disconnect the intake and exhaust pipes.
  2. Unbolt the turbo from the manifold and remove it from the engine.
  3. Install a new or refurbished turbo, ensuring all gaskets are replaced.

3. Check and Replace Wastegate Actuator

Inspect Wastegate:
- Locate the wastegate actuator connected to the turbo.
- Ensure it moves freely and has no signs of wear or damage.
Replace if Necessary:
- Remove the actuator from the turbo.
- Install a new actuator, ensuring it is adjusted to factory specifications.

4. Clean or Replace Air Filter

Inspect Air Filter:
- Remove the air filter housing cover.
- Check the air filter for dirt or blockages.
Replace if Clogged:
- If dirty, replace the air filter with a new one that meets OEM specifications.
