Hey, thanks for your experience! My Adam has the 1.4 liter engine (Z14XEL). By the way, I'm at 103456 km and did the last service about 6 months ago. I'll definitely bring up your tip about the engine control unit when I go to the garage. Hopefully it's nothing too expensive. Thanks again and best regards!

Hey, cool to hear from you again and thanks for the info. Well, with my Corsa it was a similar mileage (approx. 105000 km) when the problems occurred. The 1.4 liter engine in the Adam is prone to such symptoms, especially if the ignition system is not in top condition. Another tip: After replacing my engine control unit, I also had all the spark plugs and the ignition coil checked and replaced if necessary. This significantly improved the overall engine performance and I haven't had any more problems since. Don't get too stressed about the cost, but be prepared for a thorough check. Explain your symptoms and your suspicions about the ignition coil and the engine control unit to the workshop so that they can carry out a specific check. I hope this helps you and that your Adam will soon be running like new again! Best wishes and good luck at the workshop!

Hello, I had a similar problem with my Opel Corsa (built in 2014, also petrol). I have a bit of experience with cars and prefer to go to the garage when I have major problems. In my case, the symptoms were almost identical: black smoke, check engine light, loss of power and rough engine running. After the diagnosis in the workshop, it turned out that the engine control unit was defective. The repair cost me around 1000 euros, but after that my Corsa ran perfectly again. Your assumption about the ignition coil may of course also be correct, but if you have similar symptoms to mine, it could also be the control unit. I would recommend that you have this checked in a workshop. What exact engine version does your Adam have? With a few more details, I may be able to help even better. Good luck with the repair!
