Audi A2 problems?

Hi people, I’m 28 years old now and I’m looking for a nice, economical and skilled car. The Audi A2 seems to be a really interesting possibility….but I have a few concerns when I read the problems here…it’s easy to help me Interested are all three engines for me. Asp means 1.4 liters of petrol, 1.6 FSI, and 1.4 TDI 1. 1.4 liters of TDI will always break the turbocharger. Can you narrow that down to the year of construction or are they all? Re problems? 2. 1.6 FSI, probably takes on bad gas and sometimes makes you mute. In addition extremely expensive workshop costs (inspection) further problems? 3. About the small petrol engine les i little bad. Is this the best? Is there anything to consider? Thank you for your help
