Front doors don't lock from inside

[Newconclusion]

I've got a 2014 Seat Leon Estate that doesn't lock the front doors using the lock button on the door card. The rear doors lock but both of the front doors lock for maybe 2 seconds and then unlock again.

If I lock the car using the remote then I have no issue, it's only whilst inside the car using the button on the door card.

Any idea what it might be?

I'm having the same issue on my Ibiza 6L

Probleem with the doorlock. Read out to see iff there is a fault code

Even on the 6L I'd get a fault code?

 

[Antera]

yes

Replaced the lock unit. Issue resolved, thank you
