Discovery Electrical Gremlins: Dash & Light Warning Issues

Hey there! I have some experience working on cars and had a similar issue with my 2017 Range Rover Diesel (actually traded it later for a Defender). Those warning lights can be super annoying! I had exactly the same problem, dash warnings popping up and exterior lights acting strange. Turns out it was a faulty cable connection to one of the lamps. My mechanic found that the wiring had worn out, causing intermittent connection issues. The fix wasn't too complex, but I had to leave it at the workshop for half a day. Cost me about 180 Euro to get it sorted, including labor and parts. Since then, no more warning lights or issues! Could you share more details about which specific warning lights you're seeing on your dash? Also, are all exterior lights affected or just certain ones? This would help me give you more specific advice based on my experience.

Hi again! Thanks for sharing your experience. Mine is also showing those pesky warning lights, had my latest service just 3 months ago at 87080 KM, and everything was fine until last week. In my case, it's mainly the right side lights that are acting up. The dashboard specifically shows the exterior light malfunction warning, and it's pretty unusual, sometimes it's there, sometimes it disappears. I checked the connections myself but couldn't spot anything obvious. Your suggestion about the worn-out wiring makes sense though, especially since these vehicles are known for their electrical quirks. Did your mechanic mention if this is a common issue with Land Rovers? Might just book it in and have them take a look, especially if it's a relatively quick fix like yours was.

Hey! Thanks for those extra details about your Discovery. Yeah, I totally remember going through this headache with my Range Rover. It's actually pretty spot-on similar to what I experienced, my right side lights were the troublemakers too! You know what's funny? I also did that initial check myself and couldn't spot anything obvious. These electrical gremlins can be super sneaky! When I asked my mechanic about it being common in Land Rovers, he actually rolled his eyes and said he sees this kind of thing quite often, especially in models from around 2017-2019. Quick tip from my experience, since you mentioned it's unusual, try gently wiggling the wiring harness when the lights are on (if you can safely access it). That's actually how my mechanic pinpointed the exact spot where the wiring was worn. If the warning light flickers when you do this, bingo, you've probably found your culprit! Honestly, given that your car's done 87080 KM, it's about the same mileage where mine started acting up. I'd definitely recommend getting it checked out professionally. Better safe than sorry, especially with these electrical issues, they can sometimes lead to bigger problems if left unchecked. Just keep an eye on it until you can get it to the shop. And yeah, fingers crossed it's as straightforward as mine was! Let me know how it goes?

I'll complete the conversation from's perspective: Thanks so much for all that detailed info! Just tried your tip about wiggling the wiring harness, and wouldn't you know it, the warning light definitely flickered when I touched the right side! You're absolutely right about getting it checked professionally. I've already called my mechanic and booked it in for next week. Really appreciate you sharing your experience, it's super helpful knowing it's a known issue with these models. At least it sounds like it won't break the bank to fix! I'll definitely update you once it's sorted. Crossing my fingers it's just a simple wiring issue like yours was. These Land Rovers sure keep us on our toes with their quirks, don't they? Thanks again for all your help!
