Why does my 1990 Audi 80 sometimes have trouble starting?

Recently, my 1990 Audi 80 has been struggling to start, especially in colder weather. The engine will crank but won't turn over for a few tries. What could be causing this issue and how can I fix it?

It's possible that your battery is failing, causing lower starting power. There could also be an issue with your spark plugs or fuel filter. I recommend getting your battery and spark plugs checked, and replacing the fuel filter if necessary.
