Brilliant, my 03 Octavia 4x4 Estate started showing very similar symptoms just 4 days ago. My central locking would immediately relock as soon as I unlocked either with key or plip. I had to open the door as soon as I unlocked or it would have locked agin before I opened the door. No randomness for me. I had worked out it was related to the boot door by taking the cover off and unplugging the open door sensor, then when the back door was open I could unlock the central locking and it wouldn't relock. I was assuming the back door sensor was faulty and came online to look for a replacement when I decided to do a quick search for anyone with a similar issue. Found this thread within minutes. Just went and checked and the washer pipe had disconnected and the electrics were awash with washer fluid. Took most of the water out with a cloth then 20 mins with a hair dryer a quick spray with WD40 and my central locking is back to normal.
Chuffed, thanks.
