The vehicle had been to two mechanical workshops and a transmission specialist workshop with the fault still present. The transmission specialist advised that the issue appeared to be electrical rather than an internal CVT transmission fault. The vehicle was in limp home mode and displayed a transmission service required message on the instrument cluster.

Testing confirmed the vehicle was operating in limp mode with a persistent transmission speed sensor fault. Previous repairs had focused on replacing the wrong sensor position, which allowed the fault to remain. Diagnosis confirmed the issue was not an internal CVT failure, but an incorrect identification of the turbine, primary and secondary speed sensor locations.
