Description

The BMW ICOM NEXT (Integrated Communication Optical Module NEXT) is BMW Group’s professional factory-level diagnostic, coding, programming, and ECU communication interface. It is the official hardware used by BMW dealerships and advanced workshops to connect BMW vehicles with BMW diagnostic software such as ISTA. It supports diagnostics, software updates, ECU programming, coding, calibration, and troubleshooting across BMW, MINI, Rolls-Royce, and many BMW Motorrad (motorcycle) models.

Product Overview

BMW ICOM NEXT is the successor to the earlier ICOM A1 and ICOM A2 interfaces. It was developed to provide faster communication, improved reliability, increased processing power, and compatibility with modern BMW vehicle networks, including Ethernet, CAN FD, and DoIP (Diagnostics over Internet Protocol).
