battery draining power

[carterleeds]

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

ok cool. thanks for that. ive had this problem for like 6months since the new battery went in. where exactly do i have to look in VCDS? battery regulator??

so can i just ring up audi and ask them to update the battery ecu? will they know what im talking about?

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

ok thanks will check and let you know how i get on

which audi did you use? leeds audi?

i got my parts from there for the facelift, i dealt with a guy called lance, very helpful guy, unlike some of the other clowns there. but if you ever need parts always ask for lance he knows what he is doing.

yes leeds audi

the last part i went for was the update disks for mmi

i waited for them to come in

when they rang me i drove down there to collect they had lost it, said they would order another and post it to me, never did
