The A3 was bought in May 2018 with around 98.800 km and now has 122.300 km on the clock. So far I did one oil change and gave her some new spark plugs as they apparently haven’t been changed for 6 years. As FSI engines love to destroy ignition coils I also had to change those, 4 new ones at 40€ each. Ouch. But well worth it as it runs a bit smoother now. Besides that nothing serious happened which is quite unusual for an Audi. To the next 20.000 km.
