My battery drain problems are almost fix now.

 

Its the engine bay fans that keep going for 5 seconds then are off for 5 seconds and then starts again.....

 

what is it that is controlling the fan? The coolant tempeture guage in the car is working fine.

 

does anyone have a wiring diagram for octavia mk2 vrs pre fl?

 

I had same problem recently so I Googled. "skoda octavia fan stays on"

There was a few items that popped back but the one that worked for me was that some water had got into the external fuse box after I had rinsed the engine bay.... I tried the hair dryer on it which I didn't think worked that well. It might have displaced some water but not all off it, so I sprayed it with electrical cleaner and that solved it... Hope it's as easy as that for you.

Is the AC switched on?

does your cluster display the correct outside temperature?

Did you find a fix to this? I have same fault but also have EML light on showing fan1 control circuit low?
