hi there,
just a quick note. the one and only time i had fault lights go on /the dash lighting up on me like an xmas tree, it ended up being a bad battery. i think the service guy said it had a bad cell?? it was covered under warranty. i was not doing any off road stuff or down hill, etc. just went and started the car in the garage, it acted up/lit up. i turned it off and than tried to restart it and could not even get it to turn over. had to have it towed to the service center. service also said the electronics and sensors are VERY sensitive. i have an 05 lr3 hse. i got a new battery out if it. hopefully you can too.
