New battery q7

**h2bnd** · 10-02-2015,01:01 PM

May have to fit a new battery, think its the original sounding abit tired, alternators not that old, is there anything I need to know, I read somewhere about coding? Or is it a straight fit

You need a code off the battery or something to put into vcds so the car charges the battery different.
Have you activated the battery meter in the mmi?

picking up my Q7 tomorrow and the dealer has just fitted a new battery and had to code it to the car so will find out more then

Thanks for responding, I've only only got autel vag 505 that only reads codes. I wonder if it broke down and is fitted by RAC would they have the computer, I didn't know there's a battery meter on the mmi, get the wife to have a look tomorrow, thanks again

It needs to be activated to find it.
Have a nosey here, stemei.de .VCDS Codierungen .Codierungsservice .Webdesign - Stefan Meier - Audi A6 4F - VCDS Codierungen, Webdesign if yours is 2g mmi look more at the a64f but if it is 3q read the q7 bits.

yikes! I didn't know you have to activate the battery reading on the MMI. No wonder i can't seem to find the battery meter.

How can you do this - activation that is?

Also, I'm trying to figure out how to display the trip meter (fuel consumption etc) on my dashboard. Right now it's only showing the suspension setting and I can't figure out the MMI.

Cheers

lets hope so as its a great car, just seems funny that he said it had to have a new battery as the old one was no good and that it went flat so quickly makes me think that they didnt put a new one in but just charged the old one hoping it would last. its now gone back to audi to see whats up
