Peugeot RCZ advice

[ivanflex]

Hello ,
I wanted to ask about throttle body, my car is RCZ 2.0hdi and on a car is throttle body with double electronics and double vacuums, but car (motor) has only one vacuum hose and only one electronic cable to connect, so I want to ask is it ok or someone change it somewhen and put with double throttle body? Car always put "check" on display for throttle body

No it can be normal as modifications were made, so perfectly normal to have one not connected.

But at around 3100-3300 rpm throttle gas block and put "check" engine, when I put it on diagnosis it put mistake for throttle body, maybe is problem second vacuum which is not connected? If I bought with one vacuum and one electronic and disconnect this hose (no 1 on photo) will it make some damage on motor or not
