Central Lock Issue - Unlocking the car but not locking in using the fob

Hello guys, I ve noticed that for some reason, my 05 Octy pre-fl won’t unlock using the button on the remote. Now, i have a few a info to share that might help you

1. i’m not sure if the central lock is oem or it was installed by the prev owner as i have a blue led right next to my ESP button that s flashing when the car is locked, although i have the original skoda key with the remote, not an aftermarket one for the central locking

2. as i said, i have that blue led that s flashing when the car is locked. if i lock the car using the remote, that led starts to flash, but when i unlock the car using the remote, the blue light stops flashing, as it should, but the doors are still locked and when i press on the lock button again, the led will start flashing and the sidelights will flash just as normal, thing which is not doing on the unlock part.

3. when i m inside the car and try to lock/unlock the car from the remote, it locks just fine, but when i press the unlock button, i can hear like a click click noise, led light stops flashing and the doors are still locked unless i turn on the ignition

4. i do have a fault code on address 42, door elect. driver:

00928 - Locking Module for Central Locking; Front Driver Side (F220) 
            008 - Implausible Signal - Intermittent

i already tried to turn the key to position 1 in the ignition and press the unlock button, which worked, the remote worked for like a day after that and then went back to not unlocking the car and the ignition thing does not work anymore

i have also tried a new key fob battery, still the same issue

any help/advices are more than welcome as i don t know what to do anymore

i will also attach a full scan of the car from vcds
