Good shout on pulling a fuse...didn't think of that one! I wonder if the alarm system is wired that simply though... I'll have a look at the book tomorrow and see if there's a fuse I can whip out. Good point on the battery coding. I'm pretty sure I matched the specs of the old battery though, except that it wasn't an EFB. And I did register the replacement. So it should be fine? I need to have more of a dig in the software. I have obdeleven, and don't really like it...but it's better than a friend's foxwell that I borrowed previously.

The work isn't the problem, but I'm pretty limited on time and a slightly limited on funds... So I can't just throw parts at it, or spend ages faffing and poking, sadly. Would be nice if I had the time to tinker and take my time over it! Also mechanical stuff is super simple for me, but electrics are not my forte at all... Being a bit colourblind compounds the issue, haha

Battery is a Varta EFB, about a year old. It gets drawn down to about 12.3v after sitting for only a couple of days. If I charge it and leave it disconnected it's still at 12.7v after 2 days. When we got the car 2 years ago it had a connector wired into the battery. I removed it and thought nothing more of it because everything seemed fine. I bet it was a quick connector for a trickle charger though. I guess looking at the alarm would be the easiest next thing to check... Any idea how I'd find the cause of the infotainment single wire issue? I have no idea where to start on that! Thanks for the input so far!

They were around for ages prior to this - the door module faults in particular - despite clearing every once in a while. I can only think that disconnecting and reconnecting the driver's door module has sorted something out. But I'll keep a closer eye over the next few days. Still, the battery drain issue persists - anyone got any ideas how to narrow it down at least?

This car confuses me. Just rescanned for faults so I could pick up the descriptions, and half the faults are gone! Previously they were persistent, and would come back after only a few miles. But now all the door faults are gone! I guess that's a win...? Fault codes as it stands...

Hi all, I'm new here though I've lurked for a while... My partner's 2011 Octavia 1.4 TSI has a bunch of electrical faults, though everything except the alarm seems to work. Outwardly the only issue is battery drain, and that's only an issue if it's not used regularly. Driver's door: 00120 00131 01336 01336 Gateway: 00470 01331 01334 00469 Central electrics: 01134 03156 01331 01334 00978 I've lost the descriptions of them somewhere, sorry. I looked at the driver's door module and it was dry as a bone and clean - no sign of any physical or water damage. Also had a look at the wires in the door shut and they seemed good too. I'm aware that the alarm siren battery needs to be replaced, or a whole new unit, but not so fussed about that right now. Mainly looking to sort out the battery drain for now. I tried measuring for voltage drop across all the fuses, and found nothing at all. Probed every fuse in the dash and under the bonnet. Thanks in advance for any help!

Bump.... Did you get to the bottom of this? Had the garage messed up the cam timing when they installed?

Lol, dead! File no longer available.
