ECS Vanos System for BMW E39 M5 S62 5.0L

Clear BMW chassis

Improper VANOS function will cause reduced power and poor fuel economy. The VANOS system is BMWs version of variable valve timing and can be found on the intake and or exhaust camshafts. The system uses a pair of electrically actuated solenoids that direct the flow of pressurized oil to the VANOS gears. Depending on engine requirements the VANOS system can advance or retard timing as requested by the ECU.

The main reason all of the VANOS units will eventually fail is because the material used for the sealing rings from the factory is not designed for that type of environment. When this happens the only option that BMW leaves you with is buying a new and expensive VANOS unit with the same sealing rings that failed in your original unit. The VANOS system found in BMW engines is a great feature (when it’s working properly), keeping your power curve smooth and responsive especially in lower to mid RPM range. What usually goes unnoticed is the gradual loss of power within this range as the vehicle's age due to slowly failing seals within the VANOS unit. The way the VANOS system works is based off of oil pressure triggered by a solenoid that allows for a small range of timing degree adjustment, this is where the power curve is affected. When the seals begin to fail (all of them do) there is less pressure to advance the timing reducing the power in that low to mid range. Because this happens slowly it's very hard to notice a difference until you refresh your VANOS unit, then you easily realize the response you've been missing.
