Yes, in some cases, the Electronic Management Light (EML) or Check Engine Light (CEL) on a 2017 SEAT Leon could come on if there is an issue with the Front Assist system.

This guide can help to get the codes:

Did they do a CAN scan? This kind of scan goes over the entire car not just the drivetrain. You can get a CAN scanner (Controller Area Network) which will work on most cars from Amazon.

Here is a video to show you how:
