What does xDelete do?
xDelete is an app for Android/iOS smartphones/tablets released in December 2018. It allows you to switch your BMW from AWD (all-wheel drive) to full RWD (rear-wheel drive) or change the power distribution with our Sport/Snow/Custom Settings.
What is xDelete good for?
Being able to switch between modes opens up all sorts of fun possibilities. BMW and Mercedes have understood this and have made their latest and greatest AMG and M cars switchable between AWD and RWD.
By altering the power distribution, you can actively change the driving dynamics of the vehicle.
You get two cars in one. RWD in the summer, AWD in the winter.
Get rid of the understeer generated by the xDrive system
Drift your xDrive properly in dry and wet conditions
Finally: Having fun…thats all.
Your transfer case needs to be in good working condition, to use xDelete. A non-working xDrive system cannot be repaired with xDelete.
How does xDelete work?
We flash the xDrive ECU (called VGSG or LMV) with a modified data set to change the behavior of the transfer case.
Is this part of xHP?
No, xDelete is a separate application and is not related to xHP.
Do I need to keep my smartphone connected to the car at all times?
No. You only need to connect it when switching between AWD and RWD.
Does xDelete affect the rest of the car?
No. You can continue to use your vehicle as normal and all other components will work as before. In rare cases the DSC (in ON or DTC mode) will overreact in 2WD mode and pull power, despite the car being in a stable driving situation. The reason is mostly uneven wear between front and back tyres. Often this can be mitigated by changing the tyre pressure. If not, please use the xDrive Sport/Snow or Custom mode.
Can I remove the drive shafts and/or the transfer case ECU from the car?
The transfer case oil pump is driven by the front driveshafts. If these are removed, the transfer case is largely unlubricated. Therefore, the front driveshaft must not be removed, even in xDrive OFF mode.
xDelete should only be used with an intact driveline. xDelete opens the clutches in the transfer case so that no torque (xDrive OFF) or a user-defined amount (xDrive Sport/Snow/Custom) is sent to the front wheels.
The VTG (transfer case controller) still communicates with the other modules in your car (even in xDrive OFF mode), so it can't be removed.
Can I use a 2WD dyno in xDrive-OFF mode and do burnouts?
You can run your car on a 2WD dyno to measure HP/TQ and also do burnouts, but some things need to be considered.
Dyno: The vehicle must be moved away from the dyno after each run, so the clutch assembly gets lubricated again. For lubrication purposes, the vehicle should be run on the road for a mile before the next run. DO NOT run the car for extended periods on a 2WD dyno.
Burnouts: Respect the same guidelines as when running on a 2WD-Dyno. Drive the car after doing a burnout, to lubricate the clutch assembly again. Do not do consecutive burnouts, or burnouts lasting longer than 10 - 15 seconds.
Will I lose my factory warranty?
In theory, yes. In practice, the use of xDelete is not detectable by BMW testers or any other tool.
