Nonācu pie slēdziena šodien. Nav tur orģinālais radio, bet interesanti ka tā kļūda nāk no Engine
I'm guessing, but maybe this will help...
The Bentley Manual's general recommendation for can-bus (data-bus) errors is to:
(1) check all of the computer modules for error codes: engine, transmission, instruments, convenience, radio, immobilizer, etc., and fix them, and
(2) check the can-bus wiring for damage or loose connections
More specifically, this error may be related to the radio/navigation swap. The instrument cluster module (ICM), convenience control module (CCM), or immobilizer (typically part of the CCM), may need to be "adapted" to the new navigation system -- it is expecting to "see" the old radio & is complaining that the radio is not there. The error message is forwarded to everything else on the can-bus network, so the ECM logs the error even though it isn't an engine-specific problem.
Try scanning all the other modules for error codes & see what comes up.
Good Luck!
