How do I fix the idle control valve on my Audi 80?

I have been experiencing some rough idling and loss of power in my Audi 80. I suspect it could be a faulty idle control valve. How can I fix it myself?

The first thing you should do is check the electrical connections and clean them. Sometimes, buildup of dirt and grime can cause issues with the idle control valve. If that doesn't help, you may need to replace the valve entirely.

Before replacing the valve, I would recommend trying a reset procedure first. Disconnect the battery for a few minutes, then reconnect and start the car. This can sometimes fix the issue without needing to replace any parts.

If the above solutions don't work, it's likely the idle control valve needs to be replaced. You can purchase a replacement online or from a local auto parts store. Just make sure to match the part number and fitment for your specific Audi 80 model.
