Audi 5000 Power Antenna Guide: Replacement for 1978-1983 Models
If your power antenna has stopped working, here is what you need to know to get your radio reception back.
- The most common failure is a broken nylon drive cable, which causes the motor to run continuously.
- New OEM parts are not available; the primary new replacement option is a universal antenna from URO Parts.
- Replacing the entire antenna assembly is often simpler for a DIY repair than attempting to replace only the mast.
- No recalls were ever issued for this part, so repair and replacement are the owner's responsibility.
Symptoms of a Failing Audi 5000 Power Antenna
When the power antenna on your Audi 5000 begins to fail, the signs are usually easy to spot. Understanding these symptoms can help you diagnose the problem correctly.
| Symptom | What It Means |
|---|---|
| Motor Runs Continuously | You hear the antenna motor whirring or buzzing for more than a few seconds after turning the car on or off, but the mast doesn't move. This is the most common failure and almost always means the internal nylon drive cable has broken. The motor is working, but the connection to the mast is lost. |
| Grinding or Clicking Noises | Loud grinding or skipping sounds during operation suggest the teeth on the nylon cable are stripped or the gears inside the motor assembly are damaged or cracked. |
| Mast is Stuck Up or Down | If the mast won't extend or retract, it could be due to a broken cable, a bent mast section, or an internal motor failure. Sometimes dirt and grime can cause the mast sections to stick. |
| Poor Radio Reception | A sudden increase in static could be caused by a bad connection in the coaxial cable or corrosion within the antenna assembly itself. |
Choosing the Right Aftermarket Power Antenna
For a vehicle like the 1978-1983 Audi 5000, finding a brand-new original equipment (OEM) power antenna from Audi is nearly impossible. The original parts, often made by Hirschmann, are no longer in production. This leaves you with two realistic options: rebuilding the original unit or buying a new aftermarket antenna.
Aftermarket Brand: URO Parts
The most widely available new replacement is a universal-style power antenna from URO Parts. This brand specializes in providing replacement parts for older European vehicles.
- Quality Assessment: URO Parts are generally considered a functional, budget-friendly solution. For a non-critical part like a power antenna on a classic car, they serve the purpose of restoring function without a high cost. While not OEM quality, they are often the only new option available.
- Installation: These are universal antennas, meaning they are designed to fit a variety of vehicles. You may need to do some minor wiring adjustments to connect it to your Audi's factory harness. The kit typically includes various mounting bases to match the fender angle.
Pro Tip: Replacing the entire antenna assembly is often easier than trying to repair the original. Repairing involves taking the motor apart to extract broken cable pieces, which can be complex. A full assembly replacement is more straightforward.

Frequently Asked Questions (FAQ)
Why does my antenna motor keep running?
A continuously running motor is the classic sign of a broken internal drive cable. The motor is trying to push or pull the mast, but since the cable is snapped, it never gets the signal to stop. It's best to disconnect the antenna's power to prevent draining your battery until you can perform the repair.
Can I just replace the antenna mast instead of the whole unit?
Yes, mast-only replacements are available. However, this repair is only possible if your motor is still in good working condition. The process involves feeding the new nylon cable into the motor. If the old cable has broken off inside the motor housing, you will need to remove the unit from the car and open it to clear out the broken pieces, which adds significant complexity.
Is the URO Parts antenna a direct, perfect fit?
It is a universal replacement, not a direct-fit OEM replica. While it is designed to work with your Audi, you should expect to make minor adjustments. This usually involves selecting the correct angle for the fender mount and splicing the power, ground, and trigger wires to your car's existing wiring.
My antenna is just sticky and doesn't go all the way down. What should I do?
Before replacing the unit, try cleaning the mast. Extend the antenna fully and wipe it down with a cloth and a mild solvent to remove dirt and grime. Then, apply a very thin layer of silicone lubricant. Do not use heavy grease, as it will attract more dirt. If this doesn't solve the problem, the mast may be slightly bent or the internal cable is worn.
Are there any recalls on the Audi 5000 power antenna?
No, there have been no recalls or safety campaigns issued by the NHTSA for the power antenna on the 1978-1983 Audi 5000. Recalls for vehicles of this age are rare and typically reserved for major safety defects.
