The BMW Vanos system is similar to the variable valve timing mechanism that is found in Honda vehicles. Essentially, the Vanos system helps engine timing adjust so that your vehicle can deliver both low-end torque and high-end power, rather than having to settle for one option or the other.

Symptoms to Look Out For
- Loss of horsepower and torque.
- Slow reaction to pressing the gas pedal.
- Slow cold starts.
- Limp mode or problems with the car computer after acceleration.
- Decreased driveability.
- Rattling noises or rough idling.
- Inconsistent idling.

Does E46 have vanos?
The standard i6 double vanos is on all the E46 6 cylinder (non-diesel, non-M3) cars (323, 325, 328, 330). All of the double vanos units have failed seals and replacing them will provide significant performance improvements and improved fuel consumption.
What is VANOS failure?
When the VANOS system begins to fail, you may feel as though your BMW doesn’t want to accelerate as quickly as it once did. It may sputter or feel like it is going to stall. This happens because your engine isn’t getting the correct amount of fuel in and it is not able to properly disperse the exhaust.
