07K105189B Audi ROTOR

It’s basically the distributor’s way of sending a high – voltage spark to the correct spark plug, at the right time. Think of it as a little switch inside the distributor. It physically rotates and connects to different terminals, kind of like a traffic controller directing electricity where it needs to go to fire each cylinder. It’s a pretty simple part mechanically, but absolutely vital. It’s part of your ignition system, obviously. The ignition system's job is to start and keep the engine running, and the rotor is a key component of that. It works with the distributor cap, the ignition coil, and all the other pieces to create the spark that ignites the air/fuel mixture in each cylinder. Without a working rotor, you won’t have that spark, and the engine won’t run. It’s found in older vehicles with distributor – based ignition systems – newer cars generally use coil – on – plug setups and don’t need a rotor. Without a good rotor, you’ll get misfires – the engine will run rough, lose power, and your gas mileage will suffer. You’ll notice if it’s going bad, usually. It can cause hard starting, especially in damp conditions. A cracked or worn rotor will cause the spark to jump incorrectly, or not at all. It acts like a shield, directing the high voltage where it’s supposed to go, so when it gets damaged the electricity kind of leaks out. It’s a relatively inexpensive part to replace, and fixing it before it causes more damage is smart. You can find them pretty easily—we stock a good range here, and Fixparts Online is another good source if you want to browse. Getting a new one is often a straightforward fix, and much cheaper than dealing with problems caused by a failing rotor.
