Brand Information
SCHNECKE
- Provider of ENGINE VARIABLE VALVE TIMING (VVT) SOLENOID products to the worldwide OEM market and aftermarket.
- SCHNECKE offers complete ENGINE VARIABLE VALVE TIMING (VVT) SOLENOID coverage for Asian, Domestic and European vehicles.
Variable valve timing solenoids (VVT) are an electromechanical device that control oil flow to the engine’s cam timing system. The powertrain control module (ECM or PCM) sends electrical pulses to an electronic solenoid that will move the mechanical portion of the VVT system depending on engine load and speed. The VVT system can advance or re-tard cam timing by altering the duration of time the valves stay open and valve overlap (time the intake and exhaust valves are open at the same time), this will give the engine the best possible performance, fuel economy, and lowest exhaust emissions under all operating conditions.
For the VVT to properly perform it is imperative that the motor oil condition be clean, be at full capacity and be of the proper oil type for the engine application. The VVT system requires proper oil pressure and viscosity to work correctly. If the oil is contaminated or low when the VVT is commanded to move there will not be enough oil volume to change cam timing and a trouble code will set. Located on most solenoids are screens, or filters, which protect the solenoid from internal damage due to contaminates. Following your vehicles recommended maintenance schedule is imperative for extended life and wo-rry-f-ree operation.

Works great in 06 e90 325iMost of the negative reviews are because they are experiencing dirty or blocked vanos back flow block valvesSee attached picture I addedThose need cleaned if and when experience any misfire vanos issuesSo, don't blame the selonoids if you replace them and experience the same issuesClean or replace the flow control valves tooDefinitely will buy again

I bought these thinking it will clear my code. It lasted for a week only.I went with OEM part and never got the code again. Some parts its worth buying Bosch Or Bmw parts.

It took me only 30 minutes from start to finish.The part fits and contains an o-ring. Most of the time was finding the right tool in my big bag. The vehicle started, held a steady idle. I hope the road test yields the removal of an error code.

My rpms would fluctuate occasionally while idling at stop lights causing the car to lunge a little bit. Also horrible fuel mileage. Pulled a code p0005 which led me to replacing these solenoids. Car runs like new. Better gas mileage, smooth steady idle and more horsepower. These are cheap and fairly easy to replace. Took me about twenty minutes. If you have symptoms like I had you may want to start with these. Highly recommended!
