Opel Captiva 2011: Alarm system malfunction and weak battery - advice and experience wanted
(Translated from German)
Summary of the thread
A 2011 Opel Captiva is experiencing issues with a malfunctioning alarm system and a weak battery, potentially linked to the anti-theft system. A similar problem in an Opel Astra was traced to a defective basic module, which controls various car functions, including the alarm system. The suggested solution is to have the basic module checked by a mechanic, as it could be the root cause of the issues. Repairing this module resolved the problem in the Astra, eliminating false alarms and restoring normal function.

Hey, thanks for the tip! Maybe it could be something like that on the Opel Captiva. Can you remember how much it cost the mechanic? And did you have any other problems afterwards or did everything go smoothly?

Hey, I'm glad if I could help! Yes, I still remember the cost. It cost me €465 to repair the damn basic module. But since then at least the problem with the anti-theft alarm system has been solved, no more false alarms. So it seems that everything is back to normal. So far there have been no further problems. Hope your Captiva goes just as smoothly, man.

Oh, okay, that's quite a lot of money. But if it works again afterwards, then it's probably worth the investment. Thanks for sharing your experience. That definitely helps me. I'll definitely make an appointment with the mechanic now and see what he says. Wish me luck that it doesn't get any more expensive!

Hello, I can tell you that I had similar problems, but with my 2008 Opel Astra. It was actually one of the basic modules that was defective. This thing controls all sorts of things like the alarm system, windshield wipers and so on. When I took the car to the mechanic, he said it was definitely a serious issue. So it shouldn't be ignored because pretty much all the important controls run through this module. My tip would be to check it out, maybe that's the cause in your case too. Good luck, man!
