my Skoda Octavia NFL (2020-Present) has a strange vibration when idling, what's causing it?

Solution

1. Preparation

• Gather tools and parts required for repair.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the battery to avoid any electrical issues during repairs.

2. Inspect and Replace Engine Mounts (if damaged)

• Tools Required: Socket set, torque wrench, jack stands
• Sub-steps:
  1. Lift the vehicle using a jack and secure it with jack stands.
  2. Locate the engine mounts (usually found on either side of the engine).
  3. Use a socket set to remove the bolts securing the damaged engine mount.
  4. Replace with the new engine mount and torque bolts to manufacturer specifications (typically 40-60 ft-lbs).
  5. Repeat for all mounts if necessary, then lower the vehicle.

3. Clean or Replace Idle Air Control Valve

• Tools Required: Screwdriver set, cleaning solvent (if cleaning), new valve (if replacing)
• Sub-steps:
  1. Locate the idle air control valve (usually near the throttle body).
  2. Disconnect the electrical connector and remove the mounting screws.
  3. If cleaning, use cleaning solvent to remove carbon deposits; if replacing, install the new valve.
  4. Reattach the electrical connector and ensure it clicks securely.

4. Check and Repair Vacuum Leaks

• Tools Required: Smoke machine (or simple visual inspection tools)
• Sub-steps:
  1. Use a smoke machine to introduce smoke into the intake system, looking for escaping smoke that indicates leaks.
  2. Inspect hoses and connections visually for cracks or loose fittings.
  3. Replace any damaged hoses or re-secure loose connections.
