Hello dear people. I’m new in this forum. Have a V70 R AWD BJ. 97 with 295,000 km. Vehicle ran so far without any problems. Until today on a splash tour first cool water temperature control ramp. Water on filled up. Light extinguishes. Then people trouble motor electronics open and does not go out. At home I rented an OBD II readout device from a buddy. This shows error PO 325 01/01. According to list this should be an electrical connection error at the tap sensor Zyl. 1. Now my problem which is Zyl. 1, which component is the tap sensor? Does someone know on this occasion if there is a repair manual for this vehicle. I would like to fix this problem myself. For good advice I would be grateful. By the way my last refueling 35 liters was already the cause? Thanks for the many tips Andreas
