Yes, when replacing the diesel pump on a 2001 Astra 2.0 DTi with a second-hand unit, you typically need to code the new pump to the vehicle's engine control unit (ECU). This is necessary because the pump is often paired with specific ECU parameters for optimal performance and security. Failing to do so may result in starting issues or poor engine performance. It's advisable to consult a professional or use appropriate diagnostic tools for the coding process.
