A faulty clock spring can cause a number of problems while it’s failing, most of which are distinct from the symptoms of a failed clock spring.
Airbag Warning Light Comes On
The most common faults of the clock spring are reported to be airbag warning lights coming on. This is due to the clock spring maintaining the airbag circuit. A broken internal track is the most common fault of the clock spring and as the airbag and restraint system checks on a MOT test include this circuit, it will result in a failure.
Horn Stops Working
The horn cables also run through the clock spring and can fail in a similar manner to the above described symptoms. In most cases a worn or fractured internal ribbon cable is the root cause of the fault.
Steering Wheel Controls Cut Out
Steering wheel controls which become intermittent when the steering wheel is turned may also indicate a clock spring fault. At first, the fault can be intermittent but will normally fail completely soon after.
Intermittent Electrical Faults at the Wheel
Intermittent electrical problems at the steering wheel, such as warning lights coming on randomly, or controls switching themselves off only to return to normal after a few miles can also be caused by a worn clock spring.

When the Steering Column Needs Checking Too
A worn steering column can cause excessive wear to the clock spring so if you have found any excessive wear or play in the steering column it would be wise to check the clock spring as well for any possible signs of wear.
A simple continuity test by a qualified mechanic will confirm whether or not the steering column needs replacing as well.
