I left my 2011 6R Automatic Polo sat idle for 3 days, after which it failed to start the engine! I was able to bump it with a battery pack and after a short run it would start fine.. Another couple of days and there was a slight struggle again so I initially thought the battery was screwed. After a trip to Halfords they say the battery is fine but it could do with a quick charge, so I broke out my battery charger and all was good. However within roughly 48hrs I could once again hear there's a slight struggle to start so I'm under the impression I have a parasitic drain somewhere. Being new to fault-finding I'm sure I'm not hunting the issue correctly so came to the experts!
My attempt so far:
- With the drivers door open, the door latch pushed into the lock position and the car "locked", I made sure the alarm was disabled (I've had that thing deafen me while nosing around before), and left the car to "sleep" for an hour.
- Checked the fuse box under the steering wheel for rouge amp draws there... fuse 23 showed 10mA draw for a slight second but then dropped to 0. Nothing else showed anything.
So I went for the "not so good method", and:
- Discounted the negative terminal of the battery
- Waited an hour
- Measured the amp draw between the terminal and the negative cable...
Since I'm looking for somewhere between ~50-75mA, and pulling fuse 23 effectively kills ALL draw on the battery, does that mean the culprit likely ISN'T somewhere on fuse 23's circuit?? Or am I going about this completely wrong?
I appreciate this question has been asked before, and the guy who created this thread viewtopic.php?t=72347 had a VERY similar story, however the fact that I can't seem to measure draw across fuse 23, but pulling it drops the draw at the battery to 0 makes me think it might be something else.
Well, thank you for reading my rant and I really appreciate any information/guidence you can give!
