Coding Xterras - Is it Possible?
I’d like to know if anyone has experience coding these trucks. I think there are some ex and current BMW owners here that may know what I am talking about, or I hope so anyway.
I owned a 2007 BMW e92 (328i coupe) and with a laptop, USB to OBD2 cable, and factory BMW INPA software, I had the ability to diagnose and manipulate functions in the cars computer system. I’m not talking about engine scanners to read and clear codes. This software (NCS Expert, EDIABAS, NFS) allowed you to turn functions on/off and change duration, like the amount of time until the lights turn off automatically.
In my previous car, I installed led turn signal bulbs and had hyper flash. Instead of cutting into my wiring and adding resistors, I found the line of code for the cold testing that occurs when you turn the car on and changed the setting from “ACTIVE” to “NOT_ACTIVE”. It was in German so it was actually “AKTIV” to “NICHT_AKTIV”, but this resolved the hyper flash cleanly and was reversible.
All 3 series cars had the same computer. Only the M3 cars displayed a digital speedometer on the dash. With the BMW software I was able to turn the digital speedometer on in my 328i. The function always existed, it just need to be turned on.
My Pro-4x has a DTE (Distance To Empty) menu on the dash that my S did not. I would think these trucks have the same computer and ship with different settings activated. I don’t see why this setting couldn’t be turned on for all Xterras.
Here’s a short list of examples that could be changed that I think could cross over:
-Fog Lights + High Beam - Allows fog lights to stay on when the high beams are on. This could be applied to our off-road and fog lights, or allow us to turn them on by themselves and shut off automatically as normal.
-High beams on when unlocking the car
-Length of time that Welcome Lights Stay on - Change to your choice.
-Enable Shift Suggestion in 6MT
-Door Dong - Disable when key is in.
-Instant MPG - Displays instant MPG in dash cluster
-Bulb Testing Warning - Cold testing bulbs in front turn signals, possible for any bulbs, disables hyper flash.
Wipers Complete - Wipers always complete cycle. Normally, when you open the door they stop where they are. This allows them to return to normal position.
-Windows Down with FOB - Press and hold the unlock button on the FOB for 5 seconds and front windows roll down.
-Corner LED Delete -Disables side marker/signal light when headlights are on.
-Seat Belt Chime - Disables seat belt chime. Not recommended but possible.
-Unlock Doors - Unlocks all doors when you remove key
-Disable windows safety feature - Opening doors will not interrupt window roll up operation. Normally, if you open a door while the window is automatically rolling up, it will stop the operation. This feature disables it.
-Front fog lights on when unlocking the car - Front fog lights on when Welcome Light activated.
"hart_einschalten" - instant on
"soft_einschalten" - gradual
"nicht_aktiv" - disabled
The BMW forum had a coding section like our Powertrain & Driveline section, so, I’m sure where this topic would be most appropriate. Anyway, it would be great if someone could shed some light on this for me.
