CRD: Clicking noise under bonnet after stopped.
When I switch the engine off and turn the ignition off for about 20 seconds there is a tapping noise like a solenoid quickly engaging and disengaging which then stops if I turn the ignition back on but do not start. When I turn the ignition off again it will start again. If I leave the car it stops after about 20 seconds. Sounds like it comming from near the front of the engine bay.
Is this normal? Any ideas?
