Hello everyone,
I will need to replace the clutch kit, flywheel, and hydraulic bearing on my 2008 C4 Picasso 2.0 HDi together with my trusted mechanic.
I would like to ask if anyone knows in detail the steps to follow using DIAGBOX before and after the kit replacement. Is it a guided procedure in the software, or are these separate interventions?
From what I have read, the following steps are involved in this sequence:
Depressurizing the robot circuit
Replacing the mechanical components
Pressurizing the robot circuit
Bleeding the circuit
Learning the minimum and maximum clutch points ???
Learning the clutch disengagement/engagement point
I would be grateful if anyone who has maybe performed this procedure could help me understand what needs to be done.

Husky.
Thinking outside of the box is better than sitting in a dark one.

I believe you do have the sequence correct there and hopefully one of our experienced members will be along to give their opinion soon. 
I used to be indecisive, now I'm not so sure!
I used to ride on two wheels, but now I need all four!

Sounds about right but i would add you must have good battery support when carrying out the procedures, if the garage doesn't have access to a good battery support unit then i would connect another running vehicle with jump leads. Without battery support i find these procedures more often than not fail.

Thanks, that surely helps. Anyway she's a more recent car and different diagnostic tool but gives an idea. As long it's a guided procedure it should't be too hard
