What is the most efficient way to diagnose and fix a malfunctioning starter in an Audi 80?

I recently found that my Audi 80 is having issues with starting, but I am unsure of the exact cause. How can I efficiently diagnose and fix a faulty starter without spending too much time or money?

First, check the battery and connections to ensure they are not the cause of the starting issue. If they are fine, the next step would be to check the starter relay and solenoid. These components are common culprits for starting problems in Audi 80s. If either of these are malfunctioning, they can be easily replaced to resolve the issue.

Another common issue with starting problems in Audi 80s is a faulty ignition switch. To diagnose this, test the voltage at the starter while attempting to start the car. If there is no voltage, the ignition switch is likely the cause and will need to be replaced. Keeping your ignition switch clean and well-maintained can also help prevent future starting issues.
