You can do a check of your vehicle and not discover a spring about to break.
I took our Citroen Xsara in for mot a number of years ago. I did a full inspection before the car went in.
I always check all the bulbs, wiper blades, hooter and the front coil springs. Brakes pad and discs are checked and replaced when I do the annual service. I drive the car at least once a week and an very aware of an issues when they start. I regularly watch the tyres for any wear.
Very really does the car pick up an advisory at mot.
This one time I parked the car in the mot parking area and gave the keys to the mot inspector. There was a bang which came from the car and immediately the mot inspector said, "that's failed." The front spring broke.
Last MOT the car passed no issues, only for the front coil spring to break a week later.
