1. ABS System Issues: The intermittent ABS light is the primary concern. Here's a breakdown of the likely culprits:
* Low Brake Fluid: Check your brake fluid level in the reservoir. Low fluid can trigger the ABS light. If low, this needs immediate attention – find the leak!
* Faulty ABS Sensor: One or more of the wheel speed sensors might be failing intermittently. These sensors tell the ABS system how fast each wheel is rotating. Dirt, corrosion, or a failing sensor itself can cause this.
* ABS Module/Control Unit: The ABS module itself could be failing. This is a more expensive repair as it's a complex electronic component.
* Wiring Problems: Worn or damaged wiring in the ABS system can cause intermittent problems. This is often overlooked but is a possibility, especially with an older car.
2. Starting-to-Roll Noise: This noise is likely unrelated to the ABS light, but could be connected to braking components:
* Brake Caliper Issues: A sticking or binding brake caliper could cause a noise when starting to roll, particularly if it's only one caliper. This is a common issue and can lead to uneven brake pad wear.
* Brake Rotors: Worn or warped brake rotors can also cause noise. Given the low mileage, this seems less likely, but possible if the car has seen infrequent use or aggressive braking.
* Wheel Bearings: While less likely, a wheel bearing could be starting to fail. This would typically produce a humming or rumbling sound, and usually gets worse with speed.
What to do:
1. Check Brake Fluid Level: This is the easiest and quickest check. Top it off only if low and *immediately* locate the leak.
2. Have the ABS System Diagnosed: A professional mechanic with an OBD-II scanner (or a scanner specifically compatible with your vehicle's year) can read the ABS system codes. This will pinpoint the specific problem within the ABS system, be it a sensor, module, or wiring issue. This is crucial for efficient repair.
3. Inspect Brakes: Visually inspect the brake calipers, pads, and rotors for any obvious signs of wear, damage, or sticking.
4. Listen Carefully to the Noise: Try to determine where the noise is coming from (front/rear, left/right) and when it's most pronounced. This will help the mechanic diagnose the rolling noise.
Don't ignore the ABS light. While it might be intermittent, a failing ABS system significantly reduces your ability to safely brake in an emergency. Get it professionally diagnosed and repaired as soon as possible. The low mileage makes it less likely to be serious wear and tear and might be a relatively straightforward fix.
