Hello dear Volvo friends, my S70 (US version) Bj 2000 is now almost completely repaired, except this stupid remote control for the central locking, does not work yet. From the first owner I got all the keys and 1 remote control. Unfortunately, this did not work even after inserting a new battery. I then drove to the Volvo dealer and thought maybe it is only necessary to learn it again. The mechanic came after 30 min and said so it can not, one must order a new software and then it wouldn’t be guaranteed that it then works.Well, I thought for now, almost 90 euros only to try, is then still too much for me. Now after reading some different threads on the topic, would have been to clarify first, if it was perhaps only on the receiver, before you poking around unnecessarily in the fog. My questions: 1. Could I take a used receiver of a V/S 70 Bj 1997 or 1998 and install it? search.My S70 is model year 2000. and I have electric as far as I’ve seen it, a lot of Denso. 2.I don’t understand why the workshop wants to order a new software, it’s all original and nothing has been changed. Does for me, either FB or receiver defective or? 3.I looked in in Vida once, where the components for the ZV are installed. There it is said, to the left of the pedals is the control unit for the ZV. That irritated me a bit, on the speedometer unit is also a unit at the top and there should normally be the receiver. 4. Would Vida show me if the receiver was defective? When reading out, no errors were shown.
