Problems Seat Terraco with misfiring for some time now
(Translated from German)
Summary of the thread
A 2019 Seat Tarraco is experiencing issues such as black smoke from the exhaust, check engine light, loss of power, rough engine, jerking, starting problems, poor fuel consumption, engine stalling, and vibrations at idle. These symptoms suggest potential problems with the ignition coil or misfiring. A similar case involved a faulty engine control unit, which required diagnosis, replacement, and reprogramming, along with checking and replacing some sensors. It is advised to visit a garage for a thorough diagnosis to prevent further damage.

Hey, thanks for your quick reply! That sounds pretty hefty. Can I ask what you paid for the repair? Were there any other problems afterwards or was everything okay? Best regards,

Hey, I'm glad my answer was helpful. So, after I went to the garage, they found out that the ignition coil was actually faulty and there were also a few misfires. That was all fixed and the car has been running smoothly ever since. The cost of repairing the defective engine control unit was around €1000. It wasn't a bargain, but after that I had no more problems and everything worked perfectly. Hope this helps you! Best regards,

Hey, thanks for the info. That does sound like a bigger problem. I took my Seat to the garage today and the mechanic also found that the ignition coils are defective and there are misfires. Just like yours. A sensor also needs to be replaced. The cost of the repair was estimated at around €900. It's not a bargain, but I hope everything runs smoothly again afterwards. In any case, the mechanic was very confident. Keep your fingers crossed that it works and that no more problems arise! Thanks again for your help and the good tips! Best regards,

Hey, that sounds pretty much like a serious problem with the engine control unit. I had something similar with my 2017 Seat Ateca. The symptoms were almost the same: black smoke, check engine light, loss of power, rough engine, and starting problems. In my case, the engine control unit was faulty. The control unit was diagnosed and replaced in the workshop. In addition, some sensors had to be checked and partially replaced to ensure that the problem was completely resolved. They also reprogrammed the engine control unit. This was a serious matter as the ECU plays a central role in the vehicle. I definitely recommend that you visit a garage as soon as possible and have a thorough diagnosis carried out. The longer you ignore the problem, the worse the damage could become. Good luck and hopefully it's nothing major! Regards,
