This code keeps coming up on vcds relating to power supply terminal 30: voltage to low. It first appeared about a month ago when my battery gave up and needed to be replaced. On ross tech it does say possible causes are a weak battery so i assumed it was that but it still is there?

Any ideas

I also get 01314 code on abs and instruments when i scan those

Have you checked your earth cables and charge rate at all yet?, On the second code, is your car mapped?

Car is mapped yes. And checked all cables and charge is good. All started happening when i tried starting the car and the battery flaked out cutting power to everything while trying to crank. Its not causing any problems just curious. I like to see no faults found when i scan it lol
