    What is vanos seal?Do you own one of the below BMW 6-cylinder cars, 1993-2006? If so then your vanos, engine variable valve timing unit, is most likely failing. These vanos units have been consistently diagnosed to fail due to deteriorating piston seal O-rings. The O-rings are made of a material that is failing in the engine environment. This causes the vanos piston seals to lose their sealing function and for the vanos unit to fail. BMW does not provide the vanos seals separately. It sells rebuilt vanos units for ~$500. New rebuilt vanos units are supplied with the same failing O-rings and have been found to significantly fail in 20k miles (32k kilometers). Vanos seals repair kits are now available from Beisan Systems. They incorporate upgraded O-rings to address the failure mode and replacement Teflon seal rings.Vanos Seals Failure SymptomsOverall loss of torque and power, particularly in the lower RPM range, < 3k. Bogging then surging at 3k RPM. Uneven power distribution and RPM transition. Engine hesitations in the lower RPM range, < 3k. Louder idle and intermittent idle RPM hiccups. Difficult takeoffs. Loss of power and bogging when AC on. Increased fuel consumption. Vanos fault codes. Double vanos cars with the M52TU engine (98/99-00) experience cold weather cold start idle jolts and possible stall.Vanos Seals Repair BenefitsOverall increase in torque and power, particularly in the lower RPM range, < 3k.
