I've started hearing a loud rattling noise coming from the rear of my car, which seems to be related to the exhaust system. It's quite noisy and I'm concerned it might be a loose component or a leak.

If the sensor is out of calibration, it may need to be recalibrated. If it's faulty, it will require replacement.

A diagnostic scan tool can check the readings from the steering angle sensor. Issues with its calibration or functionality can be identified.

If the brake fluid is low, it indicates a leak. Inspect the brake lines, calipers, and master cylinder for any signs of fluid leakage.

Locate the brake fluid reservoir under the hood and check the fluid level against the 'min' and 'max' markings. Top up with the correct type of brake fluid if low.

Depending on the diagnosis, the ABS control module may need to be repaired or replaced. This is a more complex repair.

A professional diagnostic scan is required to check for error codes related to the ABS control module. This can help determine if the module itself is the problem.

If a sensor is found to be defective, it will need to be replaced. This is a common repair for these symptoms.

Visually inspect the wheel speed sensors and their wiring for any damage or debris. A mechanic can test their functionality with diagnostic tools.

If the radiator is severely clogged or damaged, replacement may be the most effective solution.

A professional cooling system flush can help remove internal debris and sediment that may be causing blockages.
