I got the solution! I asked in a mk1 facebook group and they told me about it!

It was the damn fuse under the dash.. the left oneView attachment 35595

Now my blinkers do work when unlocking/locking!
Glad to hear that you found the reason mate. Obviously i knew those relays were there, but never noticed those fuses! I wonder what the one on the right is for? Maybe the alarm siren

Didn't knew about those fuses too.. so hidden.. why not just put them with the others, bit of a design flaw imo

I actually don't know about the right fuse, i only had the ignition on with that fuse in it so i don't create any other problems

I don't have a siren tho i think

Yeah it seems weird but i'm guessing they're both alarm related in some way, so they probably put them there to stop theives deactivating the alarm by pulling the fuse etc.
