Coding 448 created issues after flashing an update (don't ask) from 2941 to 3133 :
Code:
27786 - Valve for Electric Transmission Oil Pump
P27E3 00 [171] - Electrical Malfunction
MIL ON - Confirmed - Tested Since Memory Clear
The factory coding 348 sets the fault to intermittent and lets clear it, at the cost of the gear display obviously.
Seeing how going from 3 (011bin) to 4 (100bin) isn't a single bit change, I decided to experiment a little with ignition ON, engine OFF, selector in D.
448: Gear display, , 4=100bin
348: No display, no , 3=011bin
048: Gear display, no 0=000bin
148: Gear display, no 1=001bin
248: No gear display, no 2=010bin
548: Gear display, 5=101bin
648: No gear display, 6=110bin
748: No gear display, 7=111bin
So bit 2 is something that makes the car expect the "Valve for Electric Transmission Oil Pump" to behave different that it does on the NMS, at least with 3133, and with no bearing on the gear display
Bit 1 is the one we want, it disables the gear display
Bit 0 is unknown.
Seeing how I'd like to stay close to the factory coding on this (for all I know bit 0 could disable that valve for the oil pump!), I've now set it to 000148:
