I have owned cars with PAS for the last 50 years and never had a failure of burnt out pumps or electric motors, so it is unlikely to be my style of driving. If what you claim is a likely cause then this particular car's steering components are likely to be more 'delicate' than normal.
However I received a report from the workshop today, based on diagonostic evidence, informing me that the failure is likely to be a repeat of the initial 'software' malfunction that happened a year ago. They now suspect a particuler set of circumstances causes a temporary failure, as the system returns to normal operation automatically after a period. No mechanical damage to the motor or other parts was evident. The technicians are attempting to simulate a recurrence of the circumstances by a lengthy test drive to force the malfunction to detect what needs attention. I have my doubts if they are able to detect anything in a single test drive as over 12 months of varied driving has elapsed between the two failures. If they are unable to pin point the faulty electronics the entire PAS mangement system and/or other associated systems may have to be replaced.
Another mystery of electronics.
