Citroen removed ESP from C4 ?

[aneng]

My last C4 (an SX) had ESP, which was reassuring. My new C4 (both company cars) is an "Airdream +" and doesn't have an ESP button, but a button to deactivate the reversing sensors in it's place.

I can't find any info on whether the new car actually has ESP or not.

Does anyone know whether ESP has been removed from the Airdream+ range, or whether the option (and the button) to disable it have just been removed ?

Cheers !
