Kadjar Error Messages and System Failures

Sounds like a CAN bus issue. Has the check engine light come on at all? Does it happen more when it's cold/wet? Could be a dodgy connection somewhere grounding things out. Those Kadjars can get a bit temperamental with their electrics.

The check engine light does illuminate intermittently with the other error lamps. The errors seem to occur more frequently during cold or wet weather. Any further clarification on the 'dodgy connection'?

Right, the check engine light and the weather sensitivity pretty much confirm my suspicions. It is very likely a defective cable connection to the BUS system. The error memory isn't lying. I'd get it checked pronto at a reliable workshop. Shouldn't be catastrophic; I reckon it'll probably be a loose connector or corroded pin... but best to get it sorted before more modules start throwing tantrums.

Following your advice, a trusted workshop verified a defective cable connection to the BUS system. The repair, including diagnostics and labor, cost 155€. Your insights facilitated a swift and cost-effective resolution.
