Hi, my Polo 2005, 1,2l petrol has a battery drain problem.
When leaving the car for 2-3 days without charging och running it, voltage is ~11V (from being 12,7V one hour after shutting it off)
I have measured the current and the over the big fuse, going to cabin, on top of the battery box there is a current of between 0,45A and 0,25A. It goes down step-wise from 0,8A sometimes to 0,45A and occationally to 0,25A, but never lower.
Every five minute (very precise) the trottle gives a sound for ~1sec. and the flap moves a couple of millimeter back and forth.
Relay 429 is not as cold as the other relays, and seems to be drawn after car is shut off.
It seemes some electronic in the car does not go to sleep fully.
If the battery is disconnected and reconncted there is no drain until the car has been started once, then the drain is back again.
Any ideas?
