I've recently bought a 2.0 2011 Audi A3 with no clutch but the reason I'm here is because when I bought the car there was no lights on the dash but when I got the car home (on a trailer) it wouldn't start so I tried jump starting it a few times but it wouldn't go so I took the battery out to charge it after charging it it still wouldn't start so I bought a new battery (80ah) it now starts but there's several lights on the dash, abs, traction control, tyre pressure the lot I've tried clearing the cods but they come straight back on immediately I've checked fuses and I don't really know where to go from here, any help would be much appreciated

Simple things first:- 

New battery coded to car? 
Make of new battery as a matter of interest? 

It's a yuasa got it from Halfords and yes it's been coded

Hi Jake which software platform are you using as this will have a bearing on clearing codes generic systems often as not will not clear codes/lights.

Hi I have used this system before, it is better on older cars but I have found it struggles on newer vehicles often as not because it wont show underlying problems. Suggest using a more modern manufacturer specific platform, OBD Eleven or VCDS.
