battery coding
 

Hi just wondering if anybody has come across this I have changed the battery on the d3 and it wont accepted the new battery code threw vcds I have tried everything just keeps saying code rejected would the bem module be bad.
thanks trev

go back to the old code and just add +1 to the number so for example 12345678 would become 12345679, should work ok then +++

thanks for the reply I have already done that also but no joy.

What codes are you using?
What battery make did you choose off the popup list such as VARTA?

Hi sure ive tried a lot of codes but no joy and ive also tried every battery make on the popup list but no joy.
I can get the codes tonight when I get home.
cheers trev

Worth reviewing the Rosstech video guide for battery coding - can be slightly odd behaviour with number of characters and getting zero and O mixed up that can stuff it up :)

cheers mate I will give it a go.

Sorry... but no. This number tells the car how old is the battery.
I've made a huge investigation about this issue, and it's absolutely crucial in this kind of cars to make a good battery coding.

Please read this link from Audi Sport Ibérica (It's in spanish, sorry, but google translator will help you).
