Problems with Opel GrandlandX 2018: Black smoke, engine problems and loss of performance - looking for advice and solutions

Hey guys, I have a strange problem with my 2018 Opel GrandlandX, gasoline engine. It has some pretty strange symptoms: black smoke when accelerating, persistent check engine light, the engine stalls on its own, drives weak and rough, jerks when accelerating, starts poorly or not at all, stutters at idle and shakes while idling. I thought it might be due to a broken idle control, but I'm not sure. Have any of you had similar experiences and can give me any valuable tips on how you fixed it at the garage? I look forward to hearing your stories and advice. Thanks in advance!

Summary of the thread

A 2018 Opel GrandlandX with a gasoline engine is experiencing black smoke during acceleration, a persistent check engine light, engine stalling, rough driving, jerking during acceleration, poor starting, and shaking at idle. These symptoms may be linked to a defective idle control valve or its cable/plug, as suggested by a similar case with an Opel Crossland X. The recommended solution is to have the vehicle inspected at a garage, where they can check the idle control valve and read the fault codes to diagnose the exact issue.

Hey, I had a similar problem with my 2016 Opel Crossland X. I'm not really a car expert, but I do have some experience with cars. I took my car straight to the garage. In the end, it turned out that the cable/plug on the idle control valve was defective. The repair cost me 155.0 euros, after which my Opel ran like clockwork again. I could help you better if I knew more about your car. Have you seen any lights on your dashboard or received any error codes?

Hey, thanks for your quick reply! My GrandlandX gasoline engine from 2018 now has almost exactly 140683 km on it. There were no abnormalities at the last service. As I said, the check engine light is on, but unfortunately I can't tell you any specific error codes. Sounds a lot like what you described. I'll have the cable/plug on the idle control valve checked. Glad I'm not alone with this. Cheers!

Hi, no problem, I'm happy to help! Yes, from the symptoms you've described, it sounds very similar to my problem with the Opel Crossland X. However, with such complex car problems, it's always safer to go to the garage - if only because of the check engine light. They could also read out your car via OBD2 and find the exact fault code that occurs when the check engine light comes on. My recommendation is to make an appointment with the garage as soon as you can. I hope this helps and that your GrandlandX will soon be back in perfect working order! All the best!

Person1: Hey, that could really be the solution! I'll call the garage tomorrow and make an appointment. Hopefully it's just the idle control valve or the cable/plug. It's reassuring to hear that your problem has been solved. I certainly hope that the repair costs remain similar for me. I will keep you informed. Thanks again for your support and kind words. Bye!

I have a 2021 Grandland X Hybrid and the check engine light came on. When I plug the car into the electric current, the car doesn't accept the charge. In electric mode, the car doesn't go over 60km/h. Has anyone had this problem? Can someone help me? Thank you.

Hello, I have a 2021 Grandland X hybrid 1.6. Yesterday the check engine light came on. Now, when I plug the car in to charge, it says (Full Charge) but in reality I only have enough for 12km when the minimum is 60km... I should also say that in electric mode it doesn't go above 60km/h since the warning light ⚠️⚠️ came on. I appreciate any help. Thank you.

Start by checking the charging cable and connections for any visible damage or dirt that might affect charging. Ensure the charging station is functioning properly by testing with another vehicle if possible. If the issue persists, it could be related to the battery management system or a sensor malfunction. Given the safety implications, I recommend having a professional mechanic inspect the vehicle. Let me know how it goes or if you have further questions!

Check the charging port on your vehicle for any debris or damage that might be affecting the connection. If everything looks fine and the issue continues, it might be a problem with the onboard charger or battery management system. Since this can impact your vehicle's performance and safety, it's best to have a professional mechanic diagnose and address the issue. Keep me updated on your progress or if you have more questions!
