You need to get the car scanned - the fault might be a faulty component in the optical MOST loop, or it might be a break or disconnection of an optical connector. A scan should tell you which components are healthy and which are not. On a 58 plate, your car may be a facelift, in which case the "MMI unit" is the 5f multimedia unit in the glovebox (I assume it has a drive slot and also SD card slots)?

Good luck!

It sounds like you have a pre-facelift car? Is it a saloon or an Avant? On the saloons the rear lights extend into the boot for facelift cars but not pre-facelift. The pre-facelift cars have MMI 2G and facelift cars have MMI 3G, so different systems. That's why it's important to know.

If any of the modules connected to the MOST loop fail (pre or post facelift), the optical loop is broken, and nothing works on the MMI - so there are several places to look. Getting a scan is a good first step. Also having an optical bridge cable is useful - you can bypass each unit in turn and see if the MMI comes back to life.

Good luck!
