Yes im sure because i change aku from another car.
I look for CEM and looks good. I ask also Volvo specialist where is the problem and he say - i think its problem with communication on CAN Bus.
And i still dont know where start to search. I buy this car in this condition - seller say and write me on invoice "steuergeratdefekt" - so its mean ECU or CEM i think.
Sorry for my ENG - im from Poland
