battery draining power
hi guys wondering if you could help.
if i leave the cars for about 2 days my battery drains, and i dont know why the battery is brand new and right for the car, i have coded the battery in using vcds. checked connections to the battery eveyrthing seems fine. nothing seems on when the car is locked. could it be the battery control ecu/unit thats gone bad? thanks in advanced |

Leeds Audi will know, they just did mine
Check out the software on the battery Energy Manager or regulator on vcds ie on the scan below the software version is after the H11 so is 0340 if your falls in to the category on the linked info, take it in and tell them the problem you have and you want the batt manager updated to 0590 ------------------------------------------------------------------------------- Address 61: Battery Regul.

it seems my SW version is not inbetween the uodate versions. however i did notice the H02 instead of H11 like yours. does this matter aswell?

not sure what the H02 / H11 difference is, the tsb doesnt mention your very low software revision, it only states that 0240 didnt have an issue, but above did, it maybe worth a punt anyway, it shouldnt cost much and they can check whether your batterys still good and for any other drains at the same time.
you notice at the end it says how to check its Ok, if there is still an issue to track the part thats affecting it.

Also looks like Limoncello's is a C rev hardware, may make a difference to the problem too.
I'd guess the H02 is a hardware revision 02 which if there was 'original' then H01, then H02 would lead us to C
