Model/s BA Mk2 F6 Year 2005 Oil Feed line filter installed/type Stock with Filter (approx 110,000km), Earls after failure BOV fitted Yes/No Yes (120,000km), No (last 15,000km) BOV Type Stock To Intake. KM's on Turbo @ failure or current KM's if the turbo hasn't failed 110,000 @ Failure. Intake mods (ie UBP/Intercooler/pipework) Stock up until failure point. 5,000km after turbo side intake, rapid intercooler kit with plaz plenum. Average boost pressure over the life of the turbo stock roughly for first 80,000km. But before I bought it, put a boost gauge in and it was running over 22psi, quickly changed that to 15psi and the turbo failed shortly after. Since new turbo, 18PSI. No damage to new one (cross fingers).
