Hi,
I have Volvo S80 2.4 petrol 1999. After battery drain CEM lost key data.
I used Volvo S60, S80, V70, XC70, XC90 2000-2004 synchronization utility V1.4
I made key and engine is cranking but it doesn't start.
I read (0261204559) 5P08 and synchronization is lost...
I tried again, read and synchronization is always lost after ignition on/off.
Maybe the program works bad or checksum is a problem?
I need your help...
TNX

How much rubbish you leave behind, so much rubbish someone will have to read, or maybe you yourself
