Audi A4's like all VW products after 5 to 7 years everything starts either breaking or falling apart. Plastic pieces crumble when touched, electronic display issues, leaking oil, blow off valve plastic breaking... Its a great car when new and for the first 3 to 5 years. After that they just unfortunately become money pits that are a PITA compared to Hondas/Toyotas to work on and fix. But for some reason I just cant stop loving them.
