What is Xentry Passthru?

The official Mercedes-Benz diagnostic software — dealer-level access without dealer hardware

Xentry Passthru is the genuine Mercedes-Benz diagnostic and ECU programming software used by authorised dealers worldwide. Using the SAE J2534 Passthru standard, it works with your standard OBD2 interface — giving you full dealer-level capability without the expensive Mercedes Star C5 or C6 hardware.

ℹ️

What is Passthru? Mercedes Xentry Passthru uses the SAE J2534 standard, which means it works with most common aftermarket OBD2 interfaces such as MongoosePro or DrewTech — instead of requiring the official Mercedes Star C5/C6 device that costs thousands of euros. Same software, same capability, fraction of the hardware cost.
