Hi Enes,

Don't have scanner and as dash is totally blank I cannot get any readout on info display.My mechanic believes cem module(NNN) NNN-NNNNis dead and must be replaced


It can bad cem they go bad a lot but cem module must only by volvo garage replaced thr new cem must have software installed to work and all keys also get re programed and only VOLVO garage with software access to volvo can do it . You can't use a used part from another car it will not work . From what you describe if you don't have scanner and all wires going to cem test ok I would agree with you and your mechanic next move is cem module
