Compare Land Rover ECU repair quotes from specialist garages

While Land Rover was founded in 1978, most people don't know that the Series I Land Rover actually predates the brand by 30 years, making it the second-oldest four-wheel drive vehicle in history. Land Rover is also closely linked to the Royal Family, providing the first bespoke ‘State Review' car in 1953.

The brand is associated with the spirit of adventure, and it's easy to see why; not only were its vehicles the first to cross the Darien Gap, but they were also supplied for "the Olympics of 4x4" - a competition in which teams of two would drive hundreds of kilometres, tackling the most challenging terrain, competing for a win in Land Rover cars.

ECU stands for engine control unit, sometimes referred to as the engine control module (ECM). This component ensures your car's engine runs smoothly by, for example, determining the amount of fuel that goes into the cylinders. You can find out more about how it works here.

Signs of a faulty ECU include misfires, the check engine light, starting problems, and engine surges or lags. ECU testing and repairs can help you work out the cause of the problem, such as faulty wiring or a bad sensor.

ECU testing uses a diagnostic tool known as an OBD scanner, which extracts information from the car's computer and allows the technician to check fault codes.

Can an ECU be repaired? Most of the time, the answer is yes; the ECU can be reprogrammed or repaired. The same applies to water damaged ECUs, as long as the damage is minimal. Some technicians may offer mobile ECU repairs at a location that's convenient for you.
