xDelete is designed to flash xDrive systems in most BMW E- and F-series vehicles. It won't work on other car brands with similar AWD drivetrains. Please check https://www.xautomotive.com/pages/supported-cars to see if your specific BMW is supported!
Why are F-series cars built before September 2011 not supported?
We only support F-Series cars built after September 2011, as these cars have a different control module for their xDrive unit, which we need to enable xDelete.
Cars built before 2013 also often require an iSTEP update to support xDelete, as there is a minimum software requirement in addition to the above-mentioned hardware requirement. If they have never received an iSTEP update from BMW, then their software level is too old and needs to be updated first.
The update brings other benefits, such as updated DSC calibration and optimized entertainment-system software, more supported devices, etc.
Check your exact build date here, for example by entering the last 7 digits of your car's VIN to see the exact build date, not to be confused with the car's MY (model year).
Is this only for automatic BMWs?
No. It does not matter whether your car has a manual or automatic transmission. The xDrive system has nothing to do with the transmission. It's controlled by a separate control unit.
