Is Your Audi 80 Alternator Failing?
On a classic car like the 1988-1992 Audi 80, the signs of a failing alternator are usually clear and direct. Because the electrical system is simpler than in modern cars, you can often spot the problem before you get stranded. Watch for these common symptoms:
🎬 Watch: How to know if your Audi alternator is bad- Dimming or Flickering Lights: This is a classic sign. You may notice the headlights and dashboard lights get dim when the car is idling, and then brighten up when you press the gas.
- Battery Warning Light: A red light shaped like a battery on your dashboard indicates a problem with the charging system. Sometimes, other warning lights like the engine or coolant light may come on at the same time.
- Weak or Dead Battery: If the alternator isn't recharging the battery, your car will become hard to start. You might find the battery is dead even after a recent replacement or jump-start.
- Strange Noises: A high-pitched whining or a grinding sound coming from the engine area can mean the bearings inside the alternator are worn out and failing.
- Slow Electrical Accessories: Power windows that move slowly, a radio that cuts out, or a weak air conditioner fan can all be signs that the alternator isn't producing enough power.
Choosing the Right Aftermarket Alternator
For a vehicle like the Audi 80, you don't necessarily need to buy an expensive original part from the dealer. High-quality aftermarket alternators offer excellent performance and value. Here’s a breakdown of the available brands:
- Bosch (Premium Choice): Bosch was a major original equipment (OEM) supplier for Audi during this era. Choosing a new or professionally remanufactured Bosch alternator is the closest you can get to the original part's quality and fit. They are highly recommended by mechanics for their reliability in European vehicles.
- Remy (Value Choice): Remy is a well-known aftermarket brand that provides a good balance of price and quality. While generally reliable, some owners have reported occasional issues with premature bearing failure on new units. It serves as a solid budget-friendly alternative to Bosch.
- BBB Industries & MPA (Remanufactured Specialists): These companies are large-scale remanufacturers that supply parts for many store brands. A remanufactured alternator is an original unit that has been rebuilt with new wear-and-tear components like bearings and brushes. Quality can vary, so it's a good idea to buy from a retailer with a good warranty. Pro Tip: If you buy a remanufactured alternator, ask the parts store to test it on their machine before you take it home to ensure it works correctly out of the box.

What's the difference between a new and a remanufactured alternator?

A remanufactured alternator is a used OEM core that has been disassembled, cleaned, and rebuilt with new internal wear parts like bearings, brushes, and the voltage regulator. 🎬 Watch this step-by-step Bosch alternator bearing replacement and repair A quality remanufactured unit from a top brand like Bosch can perform just as well as a new one and is a great way to save money.
My battery voltage is 11.3V when the engine is running. Is that the alternator?
Yes, that is a very strong indication of a failed alternator. A healthy charging system should produce a voltage of around 14 volts when the engine is running to power the car and charge the battery. A reading below 12 volts means the alternator is not producing a charge, 🎬 See how to perform a charging system test with a multimeter and the car is running solely off battery power.
