Why is the DSA light on in your Volvo s40?

The DSA light in your Volvo S40 indicates that the Dynamic Stability Assistance system is active or has detected a problem. This system helps maintain traction and stability during driving, especially in slippery conditions. If the light remains on, it may signal a malfunction or an issue with the system's sensors. It's advisable to consult your vehicle's manual or a professional mechanic for further diagnosis and resolution.
