Ok so i have an audi 2009/12 ( The old Model)

The car have no problem , on Tester no error , but i replacement the old battery with a new battery after the old battery Dies.

So when i put the key on contact it says Battery week (But the battery is new).This is one problem

The other problem is the car don't start , when i put the key incontact and try to start it dosent working( So when i try to start it just revs on automat but don't start like i dont have battery) (I'm in winter so i was thinking the fuel freeze but this is not the problem.

What can be the problem ?

Pretty much all new(ish) VAG cars need to be told they have a new battery when you change it.

Someone with more specific info will tell you more, but I think most Audi specialists have the electronic gubbins to connect into the car's ECU & tell it that it has a new battery.

Yeah but the new baterry idk but it says Battery Weekn on the screen you know ? Is like it dosent recornize the battery.

And either with the new battery it have to start but it dosent , so the problem might be at the Start On Start Off computer of ?

Which is what I said, the ECU does not know that you have fitted a new battery until you tell it that you have.

WHY YOU NO RISHEN?

You need to plug the VAG-Com diagnostics into the car.

And with the Ross-Tech software, go to module 16????  (Energie Manager) and change the coding of the battery.

By changing the coding of it, even by 1 symbol, the system will look and read the new battery level.

Hopefully, it will work after that.

If not, then you will need to change the EnergieManager module which sits in the boot.  It is a 5-10 minute job.  You can see the unit, as it has a massive cable from the battery earth to the module just above it.  You can buy them on ebay if necessary.

 

Hope that helps!
