How to troubleshoot a clogged air filter on an Audi 80?

My Audi 80's engine seems to be struggling and I suspect it's due to a clogged air filter. How can I troubleshoot this issue and clean or replace the air filter?

First, locate the air filter housing and remove the cover using a screwdriver. Then, check the condition of the air filter. If it's dirty, use compressed air or a soft brush to clean it. If it's damaged, replace it with a new one. It's important to regularly clean or replace your air filter to ensure proper engine performance.

Another way to determine if your air filter is clogged is to inspect the color of the filter. If it's black and dirty, it's definitely time for a replacement. Additionally, if your Audi 80 is older or has high mileage, it's recommended to replace the air filter every 15,000 miles.

You can also perform a simple test by removing the air filter and starting the car. If you notice an improvement in engine performance, it's a clear sign that the air filter was clogged and needed to be replaced. Make sure to properly dispose of the old filter and follow the manufacturer's instructions for installing a new one.
