I don't belive that the well known battery drain problems on the Scenic II are down to the cam shaft sensor ? But the dephaser solenoid valve which doesn't always get the supply turned of to it when the ignition is turned off. It's cured by an ECU software update.
Hello "Recycled Scenic" thank you for your welcome :d
I just had the mentioned problems, and yes the solenoid valve supply didn't turn off,
due to the the ECU didn't get signal from the sensor to shut down.
As soon as i had replaced the sensor everything was ok.
I used this site for my trouble shooting, i had the problem for about 2 weeks and the car has now been ok for 4.
In respect for that, i posted this photos and how i did.
Are the cam shaft sensor and dephaser solenoid valve functions are related?
Does the battery drain problem only occur in the Scenic II 1.6 ?
VVT and the has been used in engines prior to the Scenic II and not had cam shaft sensors the 2.0 F4R fitted in the Scenic II doesn't have a cam shaft sensor or so I'm told by another member who owns one. Though I don't know wether this model suffers the battery drain problem?
