Astra Warning Lights & Electrical Issues, Help Needed!

Hey there! I had a similar issue with my 2014 Vauxhall Corsa last year (I have some experience working on cars, but mainly basic maintenance). The symptoms sound very familiar. In my case, it turned out to be a faulty cable connection to the headlamp unit. Initially thought it was just bulbs too, but my trusted mechanic at AutoCare found that the wiring connection had corroded. The repair cost me around 180€, including parts and labor. They had to replace some connectors and rewire a section. What model trim is your Astra? And are you experiencing this with specific lights (like headlights, taillights)? Would help me share more relevant details from my experience. Quick tip: Before heading to a workshop, check if your bulbs are properly seated, sometimes that can trigger warning lights too. But from what you're describing, might be worth having a pro look at the wiring.

Hey, thanks for sharing your experience! You're right about checking the connections, I'm getting the warning mainly for the left headlight. I have just hit 43697 KM and had my last service about 3 months ago, but this issue started recently. I've already tried reseating the bulb but no luck. The connections sound like they could be the culprit, especially given the age of the car. Did your mechanic mention how long the repair took? I'd like to get this sorted quickly since I do a fair bit of night driving. Might give AutoCare a shot if they did a good job on yours. Mine's a standard SRi trim, nothing too fancy. Did your mechanic mention if this is a common issue with Vauxhalls? I've heard mixed things about the electrical systems on these models.

Hey again! Yeah, looking at your details, it sounds exactly like what I dealt with on my Corsa. In my case, the repair took about 2-3 hours at AutoCare. They were pretty efficient, and honestly, I've been completely trouble-free since then. When I talked to my mechanic, he actually mentioned that this is a fairly common issue with Vauxhalls from that era, especially the headlight wiring connections. Something about the way they designed the connector housing makes it prone to moisture getting in, which leads to corrosion over time. The SRi trim on your Astra actually has pretty similar wiring layout to my Corsa, from what he showed me. Quick update on my repair, it's been about 14 months now, and I haven't had a single warning light since. Money well spent, if you ask me. My mechanic did suggest getting both sides checked even if only one is showing problems. In my case, the other side was starting to show early signs of corrosion too, so I got both done at once. AutoCare did a solid job for me, they even showed me the corroded parts and explained everything. Just ask for Mike if you go there, he's really good with electrical issues. By the way, have you noticed any flickering before the warning light came on? That was my first sign before things got worse.

Thanks so much for all the detailed info! That's really helpful, especially about the potential issue with both sides. Come to think of it, I did notice some slight flickering last week before the warning light showed up, but didn't think much of it at the time. Definitely kicking myself for that now! I'll give AutoCare a ring tomorrow and ask for Mike. Sounds like it's worth getting both sides checked out, even if it costs a bit more, better than having to go back again in a few months for the other side. Your experience with the 14-month trouble-free period is pretty reassuring too. Really appreciate you taking the time to share all this. It's always good to hear from someone who's been through the same thing and found a proper solution. I'll update the thread after I get it sorted in case anyone else runs into similar issues with their Vauxhall!
