Problems with the engine control light and loss of power in Opel Crossland 2019 - suspected cause: tank ventilation/DMTL valve

Hi, I had a similar problem with my Opel Grandland (built in 2017, also a gasoline engine). My experience with cars is limited, but I have experienced quite a few things. In my case, it was the engine control unit that was faulty, although this is quite rare. The garage replaced it and it worked fine. The repair cost me 1000.0 euros. Could you give me more details about your car? Has a fault diagnosis been carried out? Have you made any modifications? The more details I have, the better I might be able to help you. Best regards!

Hey, thanks for your reply. No fault diagnosis has been done yet and I have not made any modifications to the car. The mileage is 69404 km and the last service was about 6 months ago. Hopefully this will help. Greetings!

Hello, thanks for the additional information. Given the mileage, a number of things could of course be possible, but a problem with the tank ventilation system or the DMTL valve, as you suspected, can certainly not be ruled out. I would recommend that you have your car's fault memory read out. In many garages, this is free or at least quite cheap. Then you can find out exactly what the problem is and have it fixed accordingly. Hope this helps you. Good luck and let us know what it was! Best regards!

Great, thanks for the tip! I'll go to the garage and have the fault memory read out. I'll get back to you as soon as I know more. Thanks again and see you then! Greetings!
