I know a similar thread has been posted here before, unfortunately there was never a definitive conclusion. I have a '10 LR4 that a had a charging system fault light pop up a few weeks ago. It was intermittent, but ongoing (it would alternate between showing and not showing every minute or so). The other thread recommended an update to the ECM and replacing the alternator which I am waiting on now.
The part that concerns me is that the other day within 5 minutes of starting the car it threw every code at me and lit up the dash (ABS fault, gearbox failure, traction control, etc) and the car was shifting hard. After about 30 seconds with that, my dash screen and the entertainment/nav screen both went black. I got it back to the garage and left it. I was just assuming this was an extremely low battery issue since obviously not all of those things actually faulted at the same time. I could not even roll up my window.
However, I let the car sit for a day and just tried to start it and it was a tiny bit slow on the start (like a slightly low battery) but fired right up. All the codes were gone, as expected. The reason this concerned me was because if I had enough to start the car with a relatively strong start, why did all the codes get thrown? Does anyone have any pointers as to what I should do here besides alternator and the ECM update? The LR dealership acted like they had never heard of the update so I will try my indy when I am back in town. Unfortunately I think this is going to be the fix that forces me to sell, its been a great car but the unreliability is just a bit much
