When i ordered the car, i was assured that it would have the latest software, and it came with 1666, so i complained, and it was updated to comply with what was initially said. I did have a couple of faults with the 1666, one was rear lights not working, and one were parking sensors stopped working. also had a warning of air pressure loss in a tyre. Dropped the car off at the garage at 10am, and job completed after a couple of hours. Wait to see now if any faults occur
