why does my Volkswagen Tiguan make a whining noise when I accelerate?

Solution

1. Preparation

• Gather required tools and parts.
• Park the vehicle on a flat surface and engage the parking brake.
• Disconnect the battery negative terminal to ensure safety.

2. Inspect and Replace the Serpentine Belt

1. Remove the engine cover if necessary.
2. Using a socket wrench, relieve tension on the serpentine belt tensioner.
3. Carefully remove the belt from the pulleys.
4. Inspect the belt for signs of wear or damage; replace if necessary.
5. Install the new serpentine belt by routing it according to the belt routing diagram.
6. Reapply tension using the tensioner and ensure proper alignment.

3. Transmission Fluid Check

1. Locate the transmission dipstick or fill plug.
2. Remove the dipstick and wipe it clean, then reinsert and check the fluid level.
3. If low, add the appropriate type of transmission fluid (consult the owner’s manual for specifications).
4. If fluid is burnt or contaminated, consider a fluid change and filter replacement.

4. Additional Inspections

1. If the problem persists, inspect the differential and transfer case.
2. Check for fluid leaks around seals and gaskets.
3. If found, replace any damaged components or seals as needed.
