Hi all. First time Land Rover owner and Newbie to this forum (long time reader, first time post!). Hoping for insight from you all. I have a 2012 LR4 HSE which is still under warranty (CPO). Since I purchased the truck 6 months ago, while driving at night the headlights will briefly dim (for a second). It keeps doing this seemingly every 10 min. I took it into the LR dealer and they ran a bunch of tests couldn't find the issue but updated the computer and checked the electrical systems and sent me on my way. STILL had the issue! I brought it back and this time they went through the whole truck, found no issues, no fault codes and had a "specialist" look at it. They decided to check all the grounding on the wires on the truck and then sent me home. Same flickering/dimming issue. I am at a loss what this issue could be. I am sick of bringing it in. I am not being charged due to the CPO but what a waste of time. Any thoughts? Thanks in advance for any help.
