In a candid and detailed video, Dean Lomas, also known as The Neurodivergent Mechanic, shares his experience repairing a 2018 Range Rover Evoque riddled with faults.
WHY WATCH
Dean demonstrates step-by-step diagnostics, from CAN bus troubleshooting to electrical and mechanical checks, revealing how small wiring issues can cripple modern vehicles. Packed with practical insights, frustration, and humor, it’s essential viewing for technicians.
The repair began with standard emissions-related issues: a failing SCR catalytic converter, a faulty NOX sensor, and a clogged EGR valve filter.
However, replacing these components triggered further problems; jammed steering lock, blown fuses, broken earth wires, a loose wiring pin, and communication failures in the vehicle’s CAN bus system.
Dean methodically troubleshoots using advanced diagnostic tools, consulting expert technicians, and dismantling major components including the dashboard, boot, airbox, and wiring harnesses.
His process highlights the intricate interdependency of modern vehicle systems, where a single fault can cascade across multiple modules.
