front end stays down

[thom0385]

Hi Forum

As I have mentioned in my other post "hard suspension" I have just changed the center sphere. That was a big job but everythig is asambled and along the way I got some great advises from Kees.
Now the reason for this post is that the problems have changed. Now the front end wont raise but stays down no matter what position of the selector.
Status:
Everything is tight and no leaks.
Height corrector is working
both front suspension legs new
both front spheres and center new
air bleeding proceedure carried out 15+ times
rear end goes up and down perfect
Pump is running
There is no pressure when i open the valve on top of the right side suspension leg even though I use high, low or normal height and pump is running.

Any advise/help is appreciated as im running out of ideas
Best greetings
Thomas

Sounds like air in the system. It might take a while before this is out. You might even have to put some pressure on the LDS tank to help the pump priming and pushing the air through.

@furriegurrie thank you. I have seen some posts about putting presure on the LDS tank now and i will give it a try. 0,5 bar right? seems very little that pressure

I think there's a other problem, in your other post you mentioned, that the back works fine.
This means, the pomp works properly.
Because there are no LDS comes from the right strut when you open the nippel means that the valve in the BHI is not open, you have one for the front and one for the backside.
There are 2 possible reason for this.
1e: the solenoid is broken. But every thing works fine before, i don't think this is the case.
2e: The problem comes from the high sensor, the system think that the height of the car is oke, for this reason the front valve in the BHI will not open.
So you have to use a diagbox what is wrong with the value of the front sensor.

@Kees Thank you, I will hook it up with Diagbox, do you know in what part of the diagbox i find the values?
