Have a serious problem with my XC70 2002 2,4T. The warning light for brake is almost always on (but not always). I also have warning light saying check engine, and also warning ESP.
Have changed the CEM-module, tried with another BCM, the instrument panel have been on service, and are checked, all wires have been checked and found OK.
The computer says he don't have contact with the bcm-module. After deleting all error codes the car can be fine for some time - but errors occur after some while, anyway.
Any ideas what can be the problem? What shall I check again, or next?
02 XC70 2,4T ABS-error/electrical problem?
