Hey, no problem, gladly! I had about 92,000 km on the clock when the problems occurred. Your 1.4 TSI sounds relatively similar. Of course, I also hope for your sake that it's not the engine control unit, because that can really cost a lot of money... Another tip: With these symptoms, it could also be the mass air flow sensor or the lambda sensor. These two parts can also cause a loss of power, high fuel consumption and idling problems. In my case, the mass air flow sensor was already defective once and caused similar symptoms. It wasn't quite as expensive as the engine control unit. If the garage doesn't find anything specific, it might be worth having these parts checked. Keep me posted on what your garage says! Best regards!

Hey, thanks for the tip about the mass air flow sensor and the lambda sensor, I'll definitely mention that when I go to the garage. Your experience report really helped me to get a better picture of the possible causes. I hope it's nothing too expensive, because that really wouldn't suit me at the moment. I'll definitely keep you up to date! Best regards!

Hey, I had similar problems with my Seat Leon, year 2019, also a gasoline engine. I have a bit of experience with cars, I'd say mid-level. In my case, the engine control unit was faulty. I went to the garage because the check engine light was also on and the engine was running rough - plus jerking and high fuel consumption. I also had black smoke and stalling at idle. The workshop carried out a diagnosis and determined that the engine control unit needed to be replaced. It cost me 1000 euros, but after that everything was fine again. Maybe it's the engine control unit in your case too? Which engine variant do you have and how many kilometers has your Ateca run? This will give you a better overview. Best regards!
