Hallo,

Can anyone help me?

I have problems with my s85 vanos.

No pressure at idling but 70 bars at 2000 rpm. I have changed highpressure pump and the internal hose. Even changed to new vanos units and new solinoides but still no presssure on idling. If i disconnect the cables from the solinoides ive got 70 bars on idling. The engine is mounted in a Volvo C30 and i run the engine with Delta 8000. Can there be a software problem?

A V10 C30? Pics or it didn't happen!!!!

To your question it sure sounds like something's going on with the solenoid control. Can you see if the target cam position is reached?

nice man! never heard of delta ecu. open up a build thread man. i'm sure you'll gather much interest here. with more pictures, better pictures, alot of them :)

i'd look at your delta map/config for vanos control first!

Thank you. I have contact the delta today and waiting for answers. i even have some ticking moise from solinoides so i think they dump the pressure.

Is there any way to bleed the vanos without a computer?

No. And since you're not running a stock ecu then I've no idea how you would run said routine. Is the delta ecu controlling the vanos accumulator? If not you could just remove the accumulator altogether. The system will then bleed itself over time IMO. You'd loose control of cams on startup (and noisy vanos). I'm sure there are plenty of other compromises on your build tho.

Thank you. I shall try that

No prob. Note that when removing the accumulator you want to eliminate the pipe going down to it, not just disconnect and plug at the accumulator end (that would leave that pipe section full of air - don't want that). You would have to run a custom hose from the external end of the internal vanos hose to the T feeding both vanos units.

I'm talking about eliminating #7 and running a hose direct from 9 to 8 here:

Sounds like your solenoids are being actuated by an on/off signal. They need to be controlled by a PWM signal where the ECU uses a PID routine to control solenoid current via duty cycle to match cam actual position to target position. A full bridge output isn't needed as one side of the solenoids go to ground, but the positive has to be more than just a switched output.
