High-voltage warnings after air-conditioning work need the complete service details and vehicle-specific requirements considered. The timing is relevant but does not by itself establish the failed component.
Preserve the service record
Keep equipment, materials, quantities and procedures documented by the repairer. State whether the warning appeared immediately or during later charging or driving. Do not continue operating a system displaying a serious instruction to stop.
An appropriately qualified workshop should assess the vehicle and coordinate with the original repairer. Avoid generic compressor substitutions or improvised testing. A specialist enquiry needs both the thermal-service history and full scan to distinguish a service-related issue from another electrical fault.
