How can you change the fuel filter in an Audi A4?

I noticed my Audi A4 has been having some trouble starting, and a mechanic recommended I change the fuel filter. Can someone walk me through the steps to do this properly?

First, locate the fuel filter under the car's hood near the fuel tank. Make sure the car is completely turned off and you have safety gear on, such as goggles and gloves. Then, using a wrench, loosen the nuts on either side of the filter and disconnect the fuel lines. Replace the old filter with a new one and reconnect the fuel lines, making sure the nuts are tight. Finally, turn on the car and check for any leaks or issues.
