Hi, thanks for the tip! It's interesting to know that a faulty control unit can cause such symptoms. How much did the repair in the garage cost you, if you can remember? And have you had any other problems with your Opel since then?

Yes, after I went to the mechanic, the problem with the vehicle battery and the self-discharge was solved. I paid €600 to get the faulty control unit fixed. But since then my Opel hasn't had any more problems. So it was really worth the money. I just didn't want any more trouble with the car. Hope this helps you!

Hey, thanks for the answers! That really helps me. It's good to hear that your Opel hasn't had any problems since the repair. 600€ is a lot, but if it solves the problem for good and I have peace of mind afterwards, it would be worth it to me. I will definitely visit my garage tomorrow and ask the mechanic to check the ECU. So thanks again for the helpful information!

Hello, I had a similar problem with my Opel Insignia from 2010. In my case, it was the defective control unit that caused these problems. I had it checked in my garage at the first sign. After a thorough investigation, it turned out that it was actually the control unit that was no longer working. It wasn't fun, let me tell you, but it was definitely a fixable issue. When it comes to cars, it's always better to play it safe and have it checked by an expert. You never know what could be causing it, but in my case it was definitely the ECU. Hope this helps!
