Opel Insignia 2015: Indicator light flashes, engine problems and increased fuel consumption - Possible crankcase ventilation fault?

Engine shuts off by itself

Loss of engine power

Check engine light on

Shaking while idling

Jerking on acceleration

Poor fuel economy

Unsteady engine

Hey guys, I have a problem with my Opel Insignia (gasoline engine, year of manufacture 2015) with a mileage of approx. 142,767 km. The indicator light is flashing, the engine just cuts out, feels weak, runs rough and jerks when accelerating. I can also feel it wobbling at idle and notice that the fuel consumption is quite high. I have the suspicion that the problem could be to do with the crankcase ventilation. Have any of you had similar problems and can give me some good advice for a mechanic who really knows his stuff? I had a rather bad experience with the last one... Thanks for your help! Greetings!

Hey, well, that sounds familiar. I somehow had the same symptoms with my Opel Astra (gasoline engine, built in 2012). The thing is, it was actually the crankcase ventilation. At first I thought it was something minor, but realized it was more serious. It can lead to engine damage if you don't fix it in time, so I would advise you not to take it lightly. And yes, it's important to find a reliable mechanic. The guy who fixed my Astra really knew his stuff. I can send you his contact details if you want. Stay calm, it will work out. Best regards!

Hey, that sounds really reassuring that you had exactly the same problem and were able to solve it well. It would be really great if you could send me the contact details of your mechanic! Do you happen to remember how much the whole thing cost you? And did anything else come up afterwards, or did everything run smoothly afterwards? Thank you and best regards!

Hey, I'm glad it's helping you! Sure, I'll send you the contact details right over. Now, as for the cost, I had to fork out €360 for the whole thing. The fault in the crankcase ventilation was the culprit and this was fixed by my mechanic. In retrospect, everything went well, no further problems and my car is now running like a champ again. So, don't worry, your Opel will soon be running again! Greetings!

Hey, thanks for the quick help. I'm really reassured now and look forward to contacting your mechanic soon. And €360 doesn't sound cheap, but it seems like a reasonable amount for a proper repair. I'm just glad the problem didn't recur afterwards, that would have been my main concern. Your positive experience makes me feel a bit more relaxed about the whole thing. Thank you also for the offer of contact details. I'll get in touch if I have any further questions! Take care and best regards!
