Body Acceleration Sensor Really Suddenly Defective?

Hello and good day. I briefly describe my problem. I had a wild accident. At the front was a lot wide. ( bumper, grill, radiator suspension, not the cooler itself, bonnet etc. ) The car drove however still quite normal to home and then also still 25 km to the workshop. There he stood 5 weeks, because of spare parts lack ( cooler, hood ) on the yard. When I could pick it up, the master told me it sporadicly the body acceleration sensor at the front right. was not the case until the vehicle was released. Even after the accident not. Now the error is constantly reported, with the ignition switched on already, and now also the left is also shown. It is the errors 008B and 008C interruption / ground closure. It can be quite a coincidence that the two at the same time break, but that would be a great coincidence, and then also still on the yard of the workshop standing and waiting for repair. Before I buy now 2 new sensors and they it but not are, I wanted to ask the experts here, if there are ideas, what it could still be ? A fuse ? A not really screwed mass point ? Or a too weak comfort battery ? Or yet by chance both sensors at the same time ? I am not very knowledgeable and have little idea, but for that I hope for your friendly support. I have already developed the sensors. They looked so still quite good, except for slightly cracked rubber casting, which however no Thank you for your help. Oliver. 3.0 TDI, 2012, 170 000 km.
