Concern about Opel Insignia: symptoms and possible causes
(Translated from German)
Summary of the thread
An Opel Insignia owner is experiencing issues such as black smoke during acceleration, a check engine light, longer starting times in cold weather, power loss, jerking, poor fuel consumption, and a strong exhaust odor. These symptoms suggest a potential problem with the mixture control, possibly due to a rich fuel mixture. A similar case with an Opel Zafira was resolved by replacing the fuel pressure regulator, which is recommended as a potential solution. The owner plans to have the fuel pressure regulator checked to address the issues.

Hey, thanks for the tip with the fuel pressure regulator! I'm glad it helped you. Do you happen to remember how much you paid for the repair? Has anything else come up since then or has your car been running smoothly since then? I'm really not a fan of repeated visits to the garage... Thank you for your reply!

Hey, of course I still remember that! I spent 250 euros on replacing the fuel pressure regulator. That's a bit of a bite, but since then my car has been running like a kitten again. Since the visit to the mechanic, the fault in the mixture control has finally been rectified and the mixture is no longer too rich. I haven't had any more problems since then and haven't had to go back to the garage. So it was definitely money well spent. I hope it goes as smoothly for you and that your problem is solved quickly!

Hello, that sounds reassuring! 250 is quite a lot, but if my car runs normally again like yours, it's an investment I'm happy to make. It's really a relief to hear that you haven't had any more problems since then. I will go to the garage tomorrow and have the fuel pressure regulator checked. Thank you again for your help and helpful tips. I'll keep you posted as soon as I have any news. Take care and safe driving!

Hey, I recently had similar problems with my 2013 Opel Zafira. I also noticed black smoke when accelerating and the check engine light kept coming on. After I replaced the fuel pressure regulator, the car ran as normal again. It's not a trivial defect and the repair was quite complicated, but it was definitely necessary. I can only advise you not to take your problems lightly and to check the fuel pressure regulator. Have a good trip and hopefully it's nothing more serious.
