Škoda Superb check engine light is on
(Translated from German)
Summary of the thread
A 2012 Škoda Superb is experiencing issues with black smoke from the exhaust, a check engine light, rough engine performance, jerking during acceleration, loss of power, and increased fuel consumption. The suspected cause is a defective lambda sensor heater, but a similar case with a Škoda Octavia pointed to a faulty engine control unit. The recommended solution is to have the car thoroughly diagnosed by a garage to identify the exact issue, as it may require replacing the engine control unit or addressing a simpler problem.

Hey, thanks for your answer! My Superb now has 107654 km on the clock and its last inspection was about 6 months ago. It hasn't had any similar problems so far. So it could be the engine control unit... Thanks for the tip. It's quite expensive but if it helps I'll consider it. Did your garage recognize the problem with your Octavia immediately or did it take you several attempts to find the fault?

Hey, so with my Octavia, the garage only recognized the fault after the second attempt. The first time they did a routine service and found everything to be fine. But when the problems continued, they did a more thorough diagnostic procedure and discovered the faulty engine control unit. Yes, it was expensive, but since then the car has been running great again. As for your Superb, I think a visit to the garage is inevitable. It may be something simpler, but it never hurts to have it checked. Hope this helps and that your Skoda will be running smoothly again soon!

Hello, that's really interesting. Then it seems that such problems are not so easy to recognize. I guess I'll take my Superb to the garage and have them do it. Maybe they also have the appropriate equipment to identify the exact problem without having to make several attempts. It's an expensive business, but I want my car to run smoothly again. Thank you so much for your help and the information shared. It has really helped me out!

Hi, I have limited experience with cars, but I had a similar problem with my 2010 Skoda Octavia. It turned out that the engine control unit was faulty. I had it repaired in a garage. It cost me 1000 euros to replace the unit, but since then the car has been running perfectly again. The symptoms were very similar to yours - uneven engine running, smoke from the exhaust, jerking when accelerating and increased fuel consumption. Could you please give me more information about your Superb, for example, how many kilometers it has driven and whether it has ever had similar problems in the past? Hopefully I have been able to help you a little.
