Audi A6 Quattro excessive oil consumption with repeated additions between 31,500 and 36,139 miles on Audi A6 Quattro

Some Audi A6 Quattro owners report experiencing excessive oil consumption, needing to add oil more frequently than expected, particularly between 31,500 and 36,139 miles. This problem has been a longstanding issue affecting various Audi models, with some owners indicating they must add a quart of oil every few hundred miles, highlighting a significant concern. The excessive oil consumption may be linked to specific engine components, such as piston rings or PCV failures, which could necessitate repairs or replacements. Additionally, certain engines, including the 2.0 TFSI and 1.8 TFSI, are noted for design flaws that exacerbate oil consumption, especially in models produced between 2008 and 2012. Owners experiencing these issues are advised to consult a qualified mechanic or Audi service center for diagnosis and resolution.
