Hi all we have owned our audi for a year, never had any issues, travelling back from weymouth we stopped for food went to start the car again and it came up with the fault in the dash and wouldn’t start. No other pre warning came up, we had to push the car to get it started and made it home, left the car a little bit and it started but few hours later it wouldn’t start again.

would this just be a new battery needed ?

Welcome Kelli, and thanks for joining. 
The symptoms do sound as if you have battery issues, but before simply looking to replace it, it would be wise to get its efficiency tested first. 
Halfords stores should be able to do that for you. If it’s found to be substandard, it would be well worth you letting us know before buying a new one - we should be able to point you in the right direction to buy a quality replacement at most reasonable costs. 
It would also be worth having the alternator output checked at the same time. 
Please let us now how you get on. 
Kind regards,

Gareth.

Hi I think the battery is on its way out, my daughters Q3 just did the same, the battery was just coming up to four years old so bought another Varta battery on line £155.00 if you fit a new battery its wise to fit the same brand which makes it easier to code in.
