Solenoid
for
Still waiting for the exact specs ... but it's used in Audi-s, BMW ad VWs for similar purpose.
- Resistance: R=appr. 30 Ohm ( 14.7V / R < 500 mA max).
electronic driving:
- using a free injector channel recommended: Flyback is needed.
- if there is no free injector channel in your app, the TPIC6A259 (nickname: p259) chip can drive it (TPIC6A259 is rated to 350mA if all channels are loaded continuously: otherwise it can bear max 1A on one channel). Using a flyback diode is required when driven PWM-ing, eg. BoostControl. Not strictly required for on/off applications, but still recommended.
A similar solenoid with a different connector:
R=25.1 Ohm

I like this solenoid a lot, but where can we get connectors ?
- 2x 4mm dia male 7mm between centers
- center aligning pin is also 4 mm dia, but 6 mm (between centers) from both conducting pins
Used in all Mercedes families (including E and S classes) and some Daewoo.
