Original OEM engine control module set for BMW models equipped with the N46 / N46N gasoline engine.

This is a matched starting kit supplied with its original programmed key. The supplied security components are already matched to each other. The kit is ready to install and start the engine in a compatible vehicle; separate immobilizer matching or key programming is not required for the supplied matched set. Please send your VIN and clear photos of your original module labels before purchase so we can confirm vehicle compatibility.

The main engine control unit is Bosch Motronic DME MEV17.2.1 with visible BMW part number 7581611.
