This report examines the B13C2-49 variant used across Land Rover and Jaguar engineering/program contexts (assumed to be a vehicle platform or component code). I assume the code refers to a chassis/engine/control module or platform variant shared between marques; if you meant a different item, tell me and I’ll adapt.
Part Sourcing: Ensure you get the correct part number for your specific VIN. Land Rover and Jaguar updated these sensors frequently to improve reliability.
