(1) The operation technical measures are different. Maintenance is mainly based on planned prevention, which is usually enforced. Repair is an operation carried out as planned and as needed.
(2) The operation time is different. Maintenance is usually carried out before the vehicle fails. Repair is usually carried out after the vehicle fails.
(3) The purpose of the operation is different. Maintenance is usually to reduce the wear speed of parts, prevent faults and prolong the service life of BMW; The repair usually repairs the parts and assemblies that fail or lose their working ability, so as to restore BMW's good technical condition and working ability and prolong its service life.
Relationship between repair and maintenance
BMW maintenance and BMW repair are closely related. There is maintenance in the repair, and there is repair in the maintenance. In the process of vehicle maintenance, it may be found that a certain part or part is about to fail or damage, so the maintenance opportunity can be used to repair it. In the process of repair, it is natural to maintain some undamaged parts.
Therefore, the relationship between automobile maintenance and automobile repair is dialectical. In daily activities, we must deal with the relationship between the two, insist on focusing on maintenance, and overcome the bad tendency of "emphasizing repair and neglecting maintenance" and "replacing maintenance with maintenance". This is the truth of "three points for repair and seven points for support".
