Problems with Opel Insignia 2012: Engine control light, loss of power and suspected defective EGR valve

Hi, I have some experience with cars and had a similar problem with my Opel Astra 2010 model. It turned out that the EGR valve was faulty, just as you suspected. I took my car to the garage and they replaced the EGR valve. It cost me a total of 355.0 euros, but after that the car ran perfectly again. Could you please give more details about your car? For example, have you had the fault memory read or seen any specific fault codes? This could help me to give you more specific tips.

Yes, I had the fault memory read out, but no specific fault codes were displayed. At my last service (at mileage 64324 km) everything was checked and there were no particular problems. It's so frustrating because the car was running perfectly before that. Maybe I should try an EGR valve replacement as well. Thanks for the tip!

Hey, yes, that sounds really frustrating! I can understand you very well. If there are no specific fault codes, it's really hard to say exactly what the problem is. In my Astra, the EGR valve was the solution, but of course it could be different for you. From the description of your symptoms, however, it could well be that it really is the EGR valve. The symptoms definitely point to problems with exhaust gas recirculation and engine control, which can be caused by the EGR valve. And since it also smells of exhaust fumes, it could well be that the EGR valve is broken and no longer completely tight. If I were you, I would actually consider replacing the EGR valve. Of course, it's annoying that this will incur additional costs, but if it solves the problem, it would certainly be worth it. And see if you can find an independent garage that might be cheaper than the brand-name garage. In any case, it was a significant price saving on my replacement. Keep your fingers crossed that you get the problem under control quickly!

Hello, thank you for the detailed answer and the tips! That helps me a lot. So it looks like I really should consider replacing the EGR valve. I'll have a look around for an independent garage, maybe there's an inexpensive option. It's quite annoying with the whole thing, but if it helps, then I guess it has to be done. Thanks again for the advice, that was really helpful! Keep your fingers crossed that everything works out!

Hello Are there any special maneuvers to perform to replace the egr valve on a 2018 Astra k 1.6cdti 110ch? Thanks in advance

Replacing the EGR valve can be a complex task, especially if you're not familiar with car mechanics. It involves disconnecting the battery, removing the air intake and throttle body, and then removing the EGR valve itself. However, I would strongly recommend having this done by a professional mechanic, especially as this is a relatively new vehicle. Incorrect installation could lead to further issues down the line. If you still want to proceed, I suggest getting a detailed guide or manual for your specific model. Do you have any other questions?
