Is there a good solution to the Vanos problem? To correctly address the Vanos problem the piston O-rings need to be replaced with O-rings made from higher grade material. Reduced fuel consumption, by ~10%. Resolution of double Vanos M52TU engine (98/99-00) cold weather cold start idle jolts and possible stall. Resolution of engine hesitations in the lower RPM range, < 3k. Smooth even distribution of power and RPM transition. Resolution of bogging then surging at 3k RPM. What are the benefits of repairing the Vanos? Overall increase in torque and power, particularly in the lower RPM range, < 3k. Increased fuel consumption. Double Vanos cars with the M52TU engine (98/99-00) experience cold weather cold start idle jolts and possible stall. Louder idle and intermittent idle RPM hiccups. Engine hesitations in the lower RPM range, < 3k. Uneven power distribution and RPM transition. What are the symptoms of a failing Vanos? Overall loss of torque and power, particularly in the lower RPM range, < 3k. What’s a Vanos? – Vanos is BMW’s name for its engine variable valve timing unit.
