Seat Leon Cupra Low beams headlight issue

[peter_ow]

Hi everyone,

I’m having an issue with my 2016 Seat Leon Cupra 5F. The dash is showing a “Check Headlight” warning, and the low beam/dipped on one headlight isn’t working. Oddly enough, the other lights on that same headlight (high beam, parking light, turn signal) still function just fine.

Does anyone have an idea what could be causing this? I’ve searched online for possible fixes, but I haven’t found a clear solution yet.

Any advice or experiences with a similar problem would be really appreciated. Thanks in advance!

Cheers,
Peter

@Pinky Do you mean Control unit for Headlight (part no 12 in link below)?

Yes. They changed the upper first (13) which didn't work, then the lower.
