Selespeed issue

Hello everyone,

I'm Nicolas from France and I joined the club of selespeed victims... I can't find any solution, or idea, in french communities so I'm trying here.

Here's the issue :
I have a GT selespeed from 2007. I had to replace the accumulator a year ago as I could only use 1st & 2nd gear. Everything was going well and after a while I had some other issues. After a few gear changes, pressure was dropping and the pump didn't start to get it right. I broke the bleeding screw trying to tight it up too strong, so the car didn't move for like 3 weeks. I replaced that screw and now I can't start the engine.

I checked with MES and the problem is the pressure that remains at 0.0000... the pump keeps running with no result. Then I replaced the pump but the problem isn't solved at all. Still 0 pressure in the actuator. And it's not the pressure sensor as when I unscrew the bleeding screw I have obviously no pressure (plus the oil level in the tank is not really going down).

It's like the entire circuit is always open and I don't understand why.

Pump relay is new, brake sensor is new. There's no air in the system.

Thank you if you have any lead. I hope it's all clear.

I have not seen the bleed screw removed on a Selespeed, does it have a point or is the end flat?

As you have discovered by accident, they are only designed to be gently tightened.

When the screw is tightened (not hard, just closed) and the pump operating, what is the level in the reservoir - is it within the gauge marks?
It is almost as though one of the solenoids is stuck in the “exhaust” setting.
The whole pump is new, not only the motor?
The other simple thing to check is by removing the bleed screw and taking a photograph of the hole, this will show any debris or if the thread is damaged. It’s also possible then to compare the depth of the hole, with how far the screw is going in.
I’ve another suggestion, clean the tip of your bleed screw and apply black marker pen. When it’s dry, screw into the position, tighten gently then remove immediately. The black ink should be “smeared” away to silver metal by the pressure of contact.
