Land Rover’s reputation for temperamental electrics is well-earned, but it’s often misunderstood. Whether you’re dealing with the legendary Lucas wiring in a Series III or the complex CAN bus networking in an L322 Range Rover, the root cause is usually the same: moisture, vibration, and poor previous repairs.
Both are iconic engines, but they require very different approaches to maintenance. The 300tdi is the mechanical purist's dream, no ECU, simple timing belt, and can be fixed with a basic socket set.
