Hi there! I am new to the VW ownership. I picked up a 2000 VW Golf MK4 ALH 1.9 TDI

I have been experiencing weirdness with the electronics, namely: Interior lights and back hatch.

1) It seems if I unlock the hatch from key fob or driver door, the lights will stay off for a period of time, or even locking/unlocking randomly I will not get the interior lights/floods. Sometimes even the interior lights don't want to come on when entering the vehicle as well without engaging the hatch ...VCDS shows the following:

00949
00953
01031

2) The hatch itself will unlock from the key fob or the door switch, but it will not lock, unless you pull the three wire connector out of the latch mechanism. Sometimes randomly I will find the hatch locked oddly enough on its own. The trunk light works and it does unlock from fob and door, so I know the microswitch and the motor work...when closing the light goes off and the ajar light on the dash goes off so I know the car sees it closed.

The security LED just came on tonight, by random but has been off for weeks.

I would conclude that the mix and randomness behavior seems to be the CCM. I cannot connect to the CCM on 46 either in VCDS...but I heard that this year model can only connect to the central locking module.

Things I have tried:
Replaced driver door module with new VW part
I repaired wiring and inspected while replacing door module to hinge area
Cleaned and replaced dirty or old fuses
I checked all wiring from the CCM module down through the kick plate
Inspected and patched wiring in hatch hinge areas, and to the rear C pillar
I ensured all the grounds are clean, the fuses (esp 6, 14 and 38 are in good condition, as well as the rest...) are good.
Tried cleaning all grounds and removing battery, while touching positive and negative leads together. Resetting battery will not produce a better result.
I have removed fuse 14, and when I replace it, I hear the hatch lock actuator lock...this is the only time other than pulling the plug on the latch mechanism that the hatch locks.

What I have observed:
I leave the car for perhaps 30-60 minutes, and the interior lights work randomly
All doors open do display door ajar light, including hatch
The gas tank door works
All door locks work and chime when open with key in ignition
Tried opening closing doors with key fob/lock - same behavior - hatch will unlock with key fob (lock is broken for key - cannot test)

At this point the weirdness and randomness has me leaning to the CCM behaving up. If I replace this, do I need to program it or is it a swap and good ordeal? Module: 1C0962258P
