why is my Volkswagen Golf MK7 (2015-2019) transmission fluid leaking

Solution

1. Preparation

• Ensure the vehicle is parked on a level surface and the engine is off.
• Gather tools and materials: socket set, torque wrench, transmission fluid, and a drain pan.

2. Drain Transmission Fluid

• Place a drain pan under the transmission pan.
• Remove the transmission pan bolts using a socket set. Keep track of the bolt locations for reinstallation.
• Carefully lower the pan and allow the old fluid to drain completely.

3. Inspect and Replace Gasket/Seals

• Inspect the transmission pan gasket for damage. Replace if necessary.
• Check the input and output shaft seals for leaks. If damaged, replace them.
• Clean the mating surfaces of the transmission and the pan to ensure a proper seal.

4. Reinstall Transmission Pan

• Position the transmission pan back onto the transmission.
• Apply a new gasket if required, aligning it correctly.
• Torque the pan bolts to the manufacturer's specified torque value (typically around 10-12 Nm, but refer to the service manual for exact specifications).

5. Refill Transmission Fluid

• Using a funnel, refill the transmission with the appropriate type of fluid recommended for the MK7 (usually VW G 052 162 A2 or equivalent).
• Start the engine and allow it to warm up, then cycle through all gear positions to circulate the fluid.
• Check the fluid level again and add more fluid if necessary.
