Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, stethoscope, inspection mirror, and a flashlight.
Ensure the vehicle is parked on a level surface and the ignition is off before starting any work.

2. Check Exhaust System

Sub-steps:
1. Visually inspect the exhaust system from the engine to the tailpipe for any visible damage or rust.
2. Use a wrench to tighten any loose clamps or fasteners.
3. If leaks are found, replace damaged sections of the exhaust pipe or muffler as necessary.

3. Inspect Engine Oil

Sub-steps:
1. Remove the dipstick and check the oil level; add oil if low.
2. If the oil is dirty, perform an oil change using manufacturer-recommended oil type and filter.
  - Note: Use 0W-40 synthetic oil for the Cayenne E3.

4. Examine Engine Mounts

Sub-steps:
1. Inspect the engine mounts for cracks or signs of wear.
2. If damaged, remove the old mounts using a socket set and install new mounts, tightening to manufacturer's specified torque values.

5. Inspect Intake System

Sub-steps:
1. Check the air filter for dirt and debris; replace if necessary.
2. Inspect the intake hoses for cracks or loose fittings; replace or tighten as needed.
