Installed a N18B16A from a 2016 into a 2011, HELP!
We installed a N18B16A from a 2016 into a 2011, which had the same engine, but the newer model has a different driver for the High Pressure Fuel Pump, has anyone else encountered this issue? If so, what is the resolution?Apparently on the same engine, they modified the pump from the original design and changed the mounting as well as the way it communicates with the DME. Please Advise as the engine runs and is fully installed, but not driveable.

The 2016 is throwing me off, is this even from a mini?
Not sure what other variants are out there, but this sounds like an MEVD17.2.2 vs MEVD17.2.6 ECU thing. You might need the opposite DME to what you have. I think the difference is just N18 S vs N18 JCW.
Someone else here had a thread where they swapped one engine into the other.

N14 MED17.2
N18 to Mar 2012 MEVD17.2.2
N18 post Mar 2012 and N18 JCW MEVD17.2.7
The MED17.2 & MEVD17.2.2 work with the Continental fuel pump via voltage. The MEVD17.2.7 uses a duty cycle type control method on the Bosch fuel pump.
The thermostat housing has two electrical connections. The forward one is the temp sensor. The aft one is the thermostat which is completely controlled by the ECU. There is no spring loaded mechanical element as with older style engines. When you hear some use the phrase thermostat bypass it means 12 volts has been applied to the thermostat and it is fully opened. The is no actual bypass.
...
Turns out the two ECU's use different voltages to control the thermostat. Same voltage for full open (ie bypass when AC is on max), but the intermediate voltage is different. So new 2011 thermostat being installed.
