Does anyone know if you need to program or code anything if you replace the Fuel Pump Control Unit on a 2011 BMW 535i? I want to do it myself since it's an easy fix, but I don't know if it's plug and play or if it requires coding.

Can't really say for sure, but ISTA says program module. If it's a new ECU it'd need to be programmed with the vehicle's VIN and the software aligned - if DME doesn't like to talk to it chances are car won't start.
