why does my Volkswagen Golf Eighth Generation (2020-present) make a whining noise when I accelerate

Solution

1. Preparation

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

2. Check Transmission Fluid

• Tools Required: Transmission fluid dipstick, funnel.
• Remove the transmission fluid dipstick and check the fluid level. If low, add the manufacturer-recommended transmission fluid.
• Inspect the fluid's color; it should be a clear red. If it appears dark or has a burnt smell, a transmission fluid change may be necessary.

3. Inspect and Replace Serpentine Belt

• Tools Required: Socket set, belt tensioner tool.
• Locate the serpentine belt tensioner and use a tensioner tool to release tension.
• Remove the old serpentine belt and inspect the tensioner for functionality.
• Install a new serpentine belt, ensuring it is routed correctly according to the belt routing diagram.

4. Inspect Drive Axles

• Tools Required: Jack, jack stands, socket set.
• Lift the front of the vehicle using a jack and secure it with jack stands.
• Visually inspect the drive axles for any signs of tearing or wear on the boots.
• If wear is noted, replace the affected axle(s).

5. Check Alternator and Power Steering Pump

• Tools Required: Multimeter, socket set.
• Test the alternator output using a multimeter; it should read approximately 13.8 to 14.4 volts with the engine running.
• Inspect the power steering pump for any leaks or unusual noises; if defective, replace it.
