Fabia unlocking problem

Hi , since I bought Fabia 1 combi i have some problems on the central locking / alarm.

Excuse long message but I try to describe what I know so far related to the problem .



The car came from the factory with the key operated central locking ( hub ) no remote control. After, it received aftermarket alarm with remote control. I checked the alarm connections ( Viper alarm ) and I noticed four diodes and a relay placed between alarm and the cars electrical connections .


My problem occurs occasionally ( here is the problem ) as follows : when i put the key in the ignition and start the car, central loking open / close a few times . Sometimes after a stop does not unlock if you press the release button on the door ( near the power window buttons ) again does not open , you have to pull the handle of the door to open it . Sometimes fail to lock the remote control alarm. The lock unlock at 15km/h is disabled.


These problems occur occasionally.


Can someone help me with some advice? I checked the wiring alarm wires were just twisted together , I embellished a bit and I soldered.

Could it be the aftermarket relay? can i remove it?
