Volvo S60 speedometer failure!!

Hello dear Volvo driver! The speedometer of my S60 has failed and was only at the beginning of the Bosch service. But the specialists unfortunately did not get it there. As a result I was at the speedometer service and there the repair was very expensive, because the specialists at Bosch have damaged it! (processor at the board was damaged).In addition, that also it can not be assured that the speedometer is running again! Also a new speedometer is very expensive according to Volvo! I wanted to ask if you can buy a used one, or if it is possible at all! I asked Volvo if you can learn a used speedometer on another car, but they could not answer me either. Does anyone happen to be able to do this? I need your help people because it is possible without speedometer GURNICHT! Thank me now for your answers Volvo S60 Bj. 2002 2.4 D 131 PS
