Quiescent current stage 1 & 2 intermittent

[Nard666]

They look like this for saloon & Avant. It's the top two modules that have the issue. Unplug them both and see if the is still there.

Ah ok yeah I'm with you now that's great thanks alot mate, I will let you know how I get on

Hi what was causing your powerdrain? My battery keeps running flat lasts just under a year everytime and turns slowly, i think from power being directed elsewhere, my coding for my battery regulator seems fine,was wondering if there's a common source of powerdrain? Or somewhere for me to start my search

From doing a VCDS scan, I can see that the old (original) battery data is still sitting there, which was probably from new. Is it important/significant to change/update this information after the new battery was fitted?

Am quite happy to do it - but honestly, not sure how to... presume I can do with VCDS somehow?

This is what is being reported at the moment:

Hi you want to know if it's important to clear the old faults? I'm not sure but I don't think so as when I originally first changed my battery i didn't clear the faults but it doesn't hurt to clear them anyway if you have vcds? If you have vcds there's a clear all faults button (i think it actually says clear all dtc's but i can't remember how they word it as I'm very new to vcds)

Nope - I KNOW that's VERY important!

I want to know if it's important to reprogram Module 61 with the new battery data, after the battery was changed... Some seem to think that it should be done as a matter of course when the battery is changed. Others seem to think it's entirely irrelevant. Either way, I don't know how to do it within VCDS yet anyway..

Well the side of things I thought you meant didn't seem to cause me any problems as for coding it to the car yeah i have heard mixed feelings to that too I think in most cases it will pick it up but to be on the safe side do it anyway? There's a ross-tech video on YouTube just type in battery coding using vcds -ross-tech and it should come up i stumbled across by another thread but it was under that although I think it also said wiki-how afterwards but it would pick it from that anyway

New batteries can be faulty, so take it back to the and get it checked. Also it could be an alternator fault, my alternator finally packed up this week, just waiting ton some nicer weather to change it.

Hi I've been reading through your thread on the several jobs you did on one of your motors the one where you had to change the battery and you included a link on the battery meter always showing 10 percent this was interesting as although I'm not sure mine says 10 percent (will check in the morning) it always says the same reading it's never moved in the link it says about checking the software of the battery energy manager using vcds is this just the software version for the whole car or is it just for the bem and if so where exactly am i looking? I know my software in the car is an old version maybe this is causing my battery drain, also it says in the link that update can't be done by vcds, is this true? Sorry I'm very very new to vcds so don't really understand it yet, here's my last readout from my battery regulator in case this helps?

Unfortunately I cannot find a link to the web site, and cannot remember what the correct software version should be.

The Battery monitor in the MMI software is just about useless, so don't trust it. The battery monitor was removed from later versions of the MMI system.

Its on your post from 2014 when you just a car from someone in your family, the link is just underneath the picture of your battery in the boot the link sent me to a page that seems to be under a8 or audiresources i did take a screenshot but don't know how to add it to this comment it said that it was a common fault that the battery meters showed 10 percent all the time but it said it said in most cases it didn't drain the battery but wondering if I am one of the unlucky few and i have this problem, it said the software for the bem should be updated to be: 0490 for the a6 or 0590 for the a8 and gave a part number for the update discs,they all tend to be untrustworthy then? I thought it was just mine, the only time it has ever changed is when I changed the battery the other day (I'm on my 3Rd or 4th but it's only this time the meter has changed and I think it's dropped back down again)

Thanks for that video tip... I'll seek that out tomorrow!

BTW - how do you get this dang battery condition monitor screen to appear in MMI? I don't have it in my list of options within the "CAR" MMI screen...

No worries, yeah mine was already on there and within the options for the car but you can do it with vcds, i don't know the code to add it but theirs a thread for it i will tell you how to find it..... Go to the forums page, you have to click on the audi section and then click a6 then a6 c6 and it's down as a sticky on that page it will say something like vcds changes, face-lift and pre face-lift click on that thread and it's on there with some other interesting changes you can do
