Dirt can cause the breather valves, which drain water from the drip trays during rain or vehicle washing, to become blocked. These are special rubber valves that open under water pressure.

When these valves are blocked, the drainage channels can fill up so much that a sloshing noise is heard inside the cabin, as if there were an aquarium in the car. In this case, you need to access the breather valve and clean it to allow the water to drain.

To perform this operation, remove the front wheel and the plastic wheel arch liner.

Once you access the valve, remove it, let the water drain, and clean it before refitting.

What does the red or orange zig-zag warning light mean on the Dacia Sandero?

In this video, you will learn what the warning light depicting a red or orange zig-zag on the dashboard of the Dacia Sandero means. This is a multifunction warning light; if it appears red, it is a prompt to stop as soon as possible, switch off the engine, and exit the vehicle quickly, contacting a recovery service and the Dacia Dealer. If it lights up orange, it indicates an electronic fault in the vehicle; you can continue driving, but you must reach a Dacia service centre as soon as possible. If it lights up alongside the spanner symbol, it means it is time for a service, which is due every year or 10,000 miles (whichever comes first). The service is mandatory to maintain the warranty. If it lights up together with the tyre warning light, it indicates a loss of pressure in one of the tyres. You should check all the tyres as soon as possible to identify the source of the pressure loss. If it stays on with the engine warning light, it indicates a problem with the vehicle's emissions system; if it flashes, the issue may be a component of the engine, such as the spark plugs or coil, for example. On diesel versions, it may light up alongside the glow plug symbol, indicating a related issue. If it lights up with the ESP symbol, it means there is a fault in the system that needs checking.
