BMW 320 td E46 ECU

Common issues with the ECU in the BMW 320d (E46) 3 Series can lead to intermittent engine starting problems. When the fault occurs, you may observe the absence of the engine management light and the temperature gauge quickly rising to the red zone. Communication failure with diagnostic equipment is another indicator of a faulty ECU.

Our ECU rebuilding service not only addresses the specific problem but also reinforces the ECU using superior materials and processes, preventing future recurrences. We offer a lifetime warranty with unlimited mileage, and the entire process takes 2-3 working days.
