Seat Exeo Diesel Error Message Problem

Hey there! I actually had a similar issue with my Exeo a while back. Same symptoms – error message on the dash, stored fault code… It turned out to be a problem with the control module coding. Have you tried using a diagnostic scanner to read the specific fault code? That might give you a better idea of what's going on. Sometimes a simple reset of the codes can do the trick, but if the coding is genuinely incorrect, it'll just keep coming back.

Thanks for the quick reply! That sounds promising, or at least like a lead I can follow. When you say "control module coding", what exactly do you mean? And did you manage to fix it yourself, or did you have to take it to a workshop? Just trying to gauge how deep I need to dive into this...

Yeah, by "control module coding" I mean the way the car's computer systems are programmed. Sometimes, the coding can get corrupted or just be plain wrong from the start, especially if someone's been messing around with the car's software. In my case, I wasn't comfortable messing with it myself, so I took it to a workshop. They hooked it up to their professional diagnostic scanner, confirmed the coding error, and recoded the module. It fixed the problem straight away. Honestly, unless you're really confident with engine diagnostics and have access to the right tools, I'd recommend taking it to a garage.

Wow, thanks a bunch for sharing your experience! I took it to a local mechanic, and you were spot on. The control module coding was indeed the culprit. They reset the codes and recoded the module. All in, it cost me about 360€. A bit steep, but at least the error is gone and the car is running smoothly again. Really appreciate your help!
