Hi - my eco has never worked and every now and then my car with go through a phase where the radio glitches on and off and the headlights flicker. The insides lights will asl flicker and door locks will softly click. Anyone ever experience this?

 

Similar symptoms with a 2016 LR4 i just purchased. Asked my Land Rover mechanic to check the vehicle computer's fault / error log. Didn't show any faults. No clue.

 

Sounds like you need two new batteries. There is a small motorcycle battery thats used for eco mode. If thats dead eco mode won't run. You won't always get a code for it either. Mine was out for a month or two and I didnt even notice it and no code came on. If finally came on after my indy cleared some other codes. Was odd.

And LRs are known to behave oddly if the main better starts getting low.

Test both.

 

So…what was the solution?
