The starter motor in a car is the part that provides the intitial impulse to start the engine. The pinion of the Audi starter motor connects to the ring gear on the flywheel thereby starts to turn.
If your starter motor doesn't work anymore, your car won't start. A car that won't start doesn't necessarily have a starter motor problem though. So before ordering a new starter motor, please make sure your battery is well connected and in working order just like other electrical car parts and the spark or glow plugs as the latter are equally essential for the starting of your engine.
To determine which starter adapts best to the model and engine type of your Audi, please enter your car details into the search engine.
