Description
Engine Tune for the BMW X2 M35i xDrive U10 | Developed in Switzerland and quality Made in Germany – EPA compliant
Our Engine Performance Tuning Module for the BMW X2 M35i xDrive U10 integrates flawlessly to extract maximum power and torque without faults and errors – just flawless. The harness has OEM style plugs to connect in-line with each boost pressure sensor and the camshaft position sensor on the engine as well as 12V power supplies.

Our Engine Performance Tuning Module for the BMW X2 M35i xDrive U10 is fully reversible to OEM specifications and installs in just a few simple steps. It provides a safe and reliable performance upgrade, making it the easiest and most effective way to boost your X2 U10 engine. With significant power gains, minimal installation time, full serviceability, and the ability to revert to stock at any time, this tuning module is the ultimate choice.
The dAHLer Engine Performance Tune features an advanced control unit that supports SENT technology and is specifically engineered to work seamlessly with the BMW factory ECU. Its maps and algorithms have been optimized for this engine, delivering improved fuel and ignition parameters to the stock ECU for precise boost control based on load, engine speed, and other conditions.
One of the standout features is smartphone control. With the free dAHLer Mobile App, you can wirelessly connect your module via Bluetooth 4.0 and fully customize your driving program—no additional app purchases are required.
Included in the package is an adapter that allows you to return the vehicle to its original state without removing the module’s wiring harness. This is especially useful for BMW service appointments or workshop visits.
If BMW updates the ECU software of your X2 M35i xDrive U10, the dAHLer Module remains unaffected and will not be overwritten—a key advantage over competitor products. All factory diagnostics and service access are fully retained.
The dAHLer Module is undetectable by plug-in diagnostic tools and leaves no trace behind. A valet connector is included, which can be installed in minutes to bypass the module and revert the car to factory settings. With the valet plug in place, the ECU uses the original maps instead of the modified data from the tuning module.
