This BMW TCU / TCM / EGS transmission control module (OEM 5A20559) is a used genuine part. It controls shifting behavior, gear selection, and transmission adaptation for the 2.0L turbocharged I4. A failing module can cause harsh shifts, no engagement, or limp mode. Because programming is required, this unit must be coded to the vehicle’s VIN by a qualified shop after installation.
