Seat Terraco problems with the engine, engine indicator light keeps coming on

Hey, I had a similar problem with my 2015 Seat Ateca. In my case, it was actually a defective lambda sensor. The symptoms were almost identical: black smoke, check engine light on, loss of power and strong exhaust odor. My mechanic replaced the lambda sensor and fixed the exhaust leak. This was already a serious problem because a defective lambda sensor can severely impair engine performance and lead to further damage if it is not repaired in time. After the replacement, the engine ran smoothly again and the symptoms disappeared. I would recommend that you have this checked as soon as possible. Best regards!

Hey, thanks for the info! Your description sounds pretty much like my current problem. Do you remember how much you paid for the repair? And were there any other problems afterwards or did everything run smoothly again? Regards!

Hey, yes, I can help you with that. After I went to the mechanic, the problem was actually fixed and the exhaust aftertreatment malfunction was gone. The repair cost €375 because one of the lambda sensors was defective and had to be replaced. Since then, everything has been running perfectly again and I haven't had any more problems. I hope this helps you! Best regards!

Hey, thank you! The costs aren't exactly low, but if it runs well again afterwards, it's probably worth it. I'll make an appointment with the mechanic straight away and have it checked. I hope they can get it sorted out quickly and well. Wish me luck! Best regards!
