Opel Insignia 2011: Suspected injection valve defect with unusual engine anomalies
(Translated from German)
Summary of the thread
A 2011 Opel Insignia is experiencing issues such as black smoke when accelerating, a glowing engine light, longer cold start times, loss of engine power, rough running, jerking during acceleration, and engine stuttering or shaking at idle. These symptoms suggest a potential defect in the injection valve. However, a similar case with an Opel Corsa revealed that faulty plug/cable connections could cause these issues. It is recommended to have a mechanic inspect the wiring connections before considering injector replacement.

Hey, thanks for your advice! Good to hear that it might not be as tragic as I first thought. The cable connection also sounds logical. I'm glad you were able to solve the problem with your Corsa. Do you remember how much you paid for the repair? And did your car have any more problems afterwards, or did everything run smoothly? I look forward to hearing from you. Greetings!

Hey, I'm glad my advice was able to help you. It cost me €155 to repair the broken plug/cable connection, which I think was a reasonable price. The best thing is that this repair solved all the problems you mentioned in your original post. My car has been running like clockwork ever since. And you had it spot on: I actually also had a malfunctioning fuel injector involved. But since the visit to the workshop, everything is fine again. So, don't panic, just make an appointment with a good mechanic and have him take a look. Everything will be fine. Get in touch if you have any more questions! See you then!

Hey, that's really a relief to hear about your experience and the price seems fair too. Your words have really encouraged me! Many thanks for that! I will now make an appointment with the mechanic as soon as possible and tell him explicitly to check the cable connections. Hopefully things will go as smoothly as they did for you. I will keep you informed. Thanks again and see you then!

Hi buddy, Yes, I understand your complaints well. A few months ago, my 2014 Opel Corsa had shown similar symptoms. The smoke when accelerating plus the loss of power was really strange. The juddering during acceleration was particularly annoying. The problem with my car was that the plug/cable connection was faulty. This caused almost all the symptoms you just mentioned. Although it was quite worrying, it definitely wasn't the end of the world. After a good inspection, the fault was found and the connection repaired. So, before you think about the injector, please have the mechanic do a check of the wiring connections. Hope it helps you with your problem. See you then!
