Golf 6 drainage holes are located at the bottom of the condenser in the cabin. Below is a detailed introduction to the car's air conditioning drainage holes: 1. Function: When the air conditioning is in use, the evaporator continuously absorbs moisture from the surrounding air during the heat exchange process, which condenses into water and is discharged through the air conditioning drainage hole. This is why there is often a puddle of water under the car after the air conditioning has been running for a while. 2. Causes of blockage: During the cooling process, the car's air conditioning produces condensate, and the condensate pipe is located under the chassis. During the rainy season, passing through mud and standing water can also cause the drainage holes to become blocked. The accumulated water may then flow back into the car, leading to water accumulation on the floor.

I've been driving a Golf 6 for years and know the drainage hole locations like the back of my hand. There are several key spots: The sunroof has four drainage holes hidden at each corner - front left, front right, rear left, and rear right - where rainwater drains out. Small drainage holes also exist along the bottom edges of doors, right at the sill area, to prevent water accumulation in door gaps. There might also be drainage channels under the hood and along trunk edges. If these holes get clogged with leaves or mud, water can't drain properly, leading to interior leaks, foul odors, or even body rust. During regular car washes, I always check them and gently clean with a soft brush or blower. I recommend everyone performs periodic maintenance, otherwise repairs could get costly.

As a hands-on car owner, I always enjoy maintaining my Golf 6 myself, and I've thoroughly familiarized myself with the locations of the drainage holes. The four corners around the sunroof are key areas, and there are also holes near the bottom of the doors close to the wheels, which are easy to clean. Just use a thin rope or a compressed air gun to unclog them—avoid using needles to prevent damage. If left uncleaned, water can back up under the seats during the rainy season, causing discomfort and potentially damaging the electrical circuits. I’m especially careful when parking under trees and clean them quarterly—it saves money and gives peace of mind. Remember, though small, these holes are crucial for the car's overall health.

The drainage holes on the Golf 6 are widely distributed: there are holes at all four corners of the sunroof, openings along the bottom edges of the doors, and possibly some near the chassis under the body. These holes, being constantly exposed, are prone to clogging with debris like dust or leaves, which can lead to water accumulation and corrosion of the steel panels. Regular inspection is crucial, and gentle cleaning with soft tools is recommended. Failure to clear these blockages may cause water leakage issues, compromising driving safety. Proper maintenance of these details can significantly extend the vehicle's lifespan.
