DRL not working !

[Haych]

I have a seat Leon fr, the passenger DRL is not working. There is some moisture getting in.

my question is, do I have to change the whole unit or could this possibly be just a fuse.

is there anyway I can get this fixed without changing the whole unit.

You have to replace the whole unit. If its leaking that's why the DRL has failed - they're not too expensive given the MK3 Leon has been about since 2013/14 so you'll be able to find a second hand good one for cheap enough.
