    My car won't start or even turn over and when I charge the battery it only holds the charge for so long although I don't leave the charge on for that long. I'm guessin that I need a new battery but before I go and buy a new on I've got a few questions.

    1. Will I need to reset codes etc if I remove my battery from the terminals to charge it?

    2. If I buy a new battery for my car will I lose any codes etc or is it just a streight swap without any hassel?

    Maybe I'm bein silly. Cheers

    Have your radio code handy, but no shouldnt need to do any recoding of modules/shouldnt lose any coding & if you buy a new one, look at the Varta Silver Ultra Dynamic, better than the stock Varta Blue range that audi uses.

    You ideally need to trickle charge for 1-3 days as doing quick charges all the time can damage it beyond usefulness, it needs to read 14v ideally which may/usually does subside to 12-13 after leave standing for a short while.
