How to Solve the Water Sound Inside the Volkswagen Sagitar?
3 Answers
Solutions for water sound inside the Volkswagen Sagitar: 1. Check if the water tank is leaking; 2. Inspect whether the drainage holes are blocked; 3. Drain the accumulated water inside the doors. The Volkswagen Sagitar is a compact car under FAW-Volkswagen, with body dimensions of: length 4753mm, width 1800mm, height 1462mm, wheelbase 2731mm, fuel tank capacity 50L, and body structure as a 4-door 5-seater sedan. The Volkswagen Sagitar is equipped with a 1.2T turbocharged engine, paired with a 5-speed manual transmission, delivering a maximum horsepower of 116hp, maximum power of 85kW, and maximum power speed of 5000rpm.
Recently, my Sagitar kept making water flow noises, and there was a gurgling sound under the front passenger floor when the AC was on. It's usually due to a clogged drain hole. Since the AC operation produces condensate that needs to drain out, the small opening can easily get blocked by mud, dust, or leaves. You can try fixing it yourself: use a wire or compressed air to blow through the drain pipe opening, which is located under the front passenger dashboard. For water sounds in the door, clean the drain holes at the bottom seal strip and unclog the plug to drain accumulated water. If cleaning doesn’t help or you notice a burnt smell, be cautious—it might indicate a leaking heater core or wiring issue, which can corrode the frame and cause rust. Once, I delayed fixing it, leading to moldy carpets and higher repair costs. If DIY methods fail, I suggest visiting a 4S shop for a minor fix to avoid bigger issues. Park away from leafy areas to reduce the risk, and make it a habit to check the drainage system after using the AC.
As an experienced professional frequently dealing with such issues, the water sound in Volkswagen vehicles is mostly caused by evaporator drain problems. When the AC is on, condensed moisture normally drains outside through pipes, but clogged holes lead to water accumulation in the underbody compartment, creating noise. Check the AC drain tube near the firewall and use tools to clear blockages. Door water accumulation is also common—simply clean the bottom drain holes. However, persistent water flow sounds may indicate a leaking heater core, requiring internal pipe inspection to prevent corrosion or electrical shorts. A professional technician can accurately locate the issue with a multimeter at a reasonable cost. Don’t ignore safety risks—increased water accumulation may seep into electronics, causing short circuits and parking hazards. We recommend visiting an authorized repair shop for a one-stop diagnosis, ensuring both peace of mind and safety.
