What is wrong when the BAS ESP light comes on in a Mercedes clk230?

When the BAS (Brake Assist System) and ESP (Electronic Stability Program) light comes on in a Mercedes CLK230, it typically indicates a malfunction in the vehicle's stability control or braking assistance systems. This could be due to issues such as a faulty wheel speed sensor, low brake fluid, or problems with the ABS module. It's advisable to have the vehicle diagnosed with a specialized scanner to pinpoint the exact issue and prevent potential safety risks. Ignoring the warning could lead to compromised vehicle handling and braking performance.
