How to adjust the idle speed on an Audi 80?

I've recently noticed that my Audi 80's idle speed seems to be too high. How can I adjust the idle speed to a more appropriate level?

To adjust the idle speed on an Audi 80, first locate the idle control valve, which is usually attached to the throttle body or on the intake manifold. Use a screwdriver to adjust the idle screw and lower the idle speed gradually. Make sure to keep the idle speed within the manufacturer's recommended range.

One possible reason for a high idle speed on an Audi 80 is a dirty or faulty idle air control valve. Try cleaning it with a specialized cleaner or replace it if necessary. This should help bring the idle speed back to normal.

Another potential cause for a high idle speed on an Audi 80 is a vacuum leak. Check all vacuum lines and connections for any cracks or loose fittings. Fixing any leaks should help lower the idle speed.
