Traditional (lower cost) pneumatic valve.

Used in Audi-s, BMW ad VWs for similar purpose.

Should NOT be used beyond 3 bar boost (400 kPa absolute). Actually, above 2 bar boost (300 kPa absolute), or for large wastegate actuators, the above [High flow-capacity boostcontrol valve] is recommended.

R=25.1 Ohm

I like this solenoid a lot, but where can we get connectors ?

Used in all Mercedes families (including E and S classes) and some Daewoo.
