DS5 Aircon troubles

Post by AdventureDriver »

2013 DS5 2.0 Hdi, 230k km.
Aircon started to cycle, couple of minutes on, couple of minutes off, etc...
Car went to three workshops (one of them Citroen), none could fix the problem.
Replaced high pressure sensor and brightness sensor.
After last workshop visit the aircon only works 30 seconds after engine start.
Tried bridging low pressure and high pressures (with resistor bridge) sensors but with same results.
Tried bridging blower motor control unit, same result.
Blower and blower motor control unit (resistor) seem to work fine.
Latest fault code is B1310-10.

A aircon specialist told me to replace blower and control unit, but they work.
And I would do, but getting parts in South Africa is rather difficult.

I'm out of options. Anybody has some idea?
