Opel Captiva 2010 with power loss, high fuel consumption and abnormal exhaust odor

Hey, that sounds a lot like the symptoms I had last year with my 2007 Opel Vectra Diesel. It turned out to be a cable/plug fault. However, it really was a serious issue, not a minor one. Once the electrical problems start, it can be a real mess. In my case, the car also started to stutter and lost power, just like yours. The mechanics had to replace the cable from the fuel sensor and reconnect the plug. That solved all the symptoms. You could have the same problem, the symptoms are really similar. Have it checked out in a workshop. You can contact me again and I can recommend my garage. They fixed my car back then and knew exactly what they were doing. Make sure you take it seriously and act quickly. The electrics are not to be trifled with. All the best!

Hey, thanks for your reply! Glad to hear you've got this mess behind you. I'll see if I have a similar defect. Do you have any idea how much the repair cost back then? And have you had any other problems since then, or did everything run smoothly? Let me know!

Hey, you're lucky, I still remember it all pretty well. So, the repair for the defective cable/plug cost exactly €95 back then. It wasn't cheap, but hey, what can you do, right? Since then, the car has really run like a dream. And as for the problem with the fault in the fuel composition, that has also disappeared since the visit to the mechanic. So, in the end, it was worth it. Hope that helps you a bit!

Hey, thanks for the specific details! I'm relieved to hear that your car has been running well since the repair. 95 doesn't sound cheap at first, but if it solves the problem permanently, it's worth it. I know a garage that I'm going to visit now. I hope they can help with my problem too. Thanks again!
