“SOS System Limited Functionality” warning in Range Rover

In this video, I will explain to you the meaning of the “SOS System Limited Functionality” in your Range Rover. Unfortunately, more and more people report this problem and they just don’t know that their cars are equipped with the TCU or Telematics Communication Unit and this unit has its own dedicated battery. These small lithium batteries tend to go bad after 5 to 8 years of use even though they are rechargeable. This message means that the TCU is glitching and can’t operate properly. I know that most owners would easily put up with this module not working at all, but it’s much harder to put up with the warning popping up every time you start your car. So, this video gives you open and free information on how you can solve this problem on your own spending just a little money on the new battery. Fortunately, this will help you and you will fix the issue without spending hundreds of euros on dealership labor.
