The Audi A3 1.4 TFSI comes with a timing chain, but there are potential engine issues to watch out for. Loose gaskets should be tightened promptly, and any oil leaks should be addressed without delay. A loose spark plug can lead to engine problems, while overheating poses a serious risk, potentially causing fires or even explosions. Keep an eye out for excessive oil consumption, as it may indicate the need for a prompt oil change. Remember to replace the air filter every 15,000 to 30,000 miles, the coolant every 60,000 miles, and the spark plugs every 100,000 miles, unless they're copper, in which case they should be changed every 30,000 miles.
