BMW 440i xDrive Car Starter Repair at your home or office.

When to replace the starter?

起动机s are relatively durable but most will eventually fail in one or more of the following ways:

• 开胃菜的间歇性操作。起动器可以在电枢上发展不良斑点，从而导致间歇性操作。这会导致起动器有时和有时转动钥匙的时候起作用。
• 起动机turns too slowly.Internal electrical and mechanical faults can cause the starter to draw too much current and in some cases the current drawn will exceed what the battery can supply. A consequence is the engine may not start as rapidly.
• Unusual noises on starting.If you hear any type of grinding or other unusual noise while starting the engine, that should be investigated as the noise could reflect an internal starter failure or the noise could be due to pinion gear failure or flywheel ring gear damage.
  
• 起动机doesn’t function when turning the key.在某些情况下，起动器故障的第一个症状是起动电机的完全故障。当您转动点火键以启动汽车时，就会发生这种情况，启动器电动机根本不起作用。
