Regulation at 3,500 RPM Hiunday Santa Fe 2009 2.2LT

Good afternoon, in the workshop I have a problem with a Hiunday Santa Fe 2009, 2.2 cm^3. with Common Rail Bosch injection system.
-The failure is that in idle the revolutions are regulated at 3,500 rpm and the engine seems to be plugged that he would leave his supports.
The injection system was repaired with EPS (Bosch) and Kdiesel equipment
does not present someone's fault codes,
the same has happened?
Will the turbo vgt?
Thank you very much for your opinions

Check if the VGT valve is running and if the alaves are free.
Check the catalysts there may be obstruction. In the escape.

Hi Ronaldsolano thanks for the grateful annotation.
I already checked that with the loose exostum to know if the catalyst was covered but not the turbo acts well, the empty empty, look multiple of admission, egr, of everything. And nothing
