How can I fix the low fuel pressure in my Audi 80?

I recently noticed that my Audi 80 is having issues starting and running smoothly. I suspect it has to do with the fuel pressure. How can I fix this issue?

The first thing you should do is check the fuel filter to see if it needs to be replaced. A clogged fuel filter can cause low fuel pressure and affect the performance of your car. Keep an eye on your fuel filter and replace it every 30,000 miles or as recommended by your car's manual.

If the fuel filter is not the issue, you should check the fuel pump and its relay. A faulty fuel pump or relay can also lead to low fuel pressure and cause starting and running issues. You can test the fuel pump and relay with a multimeter or take it to a mechanic.
