I scanned my car today as I have been curious since I had the remap whether I had any codes no particular reason as the car is running fine.

I have code 18010 - Power Supply (B+) Terminal 30 - Low Voltage

or Power Supply Terminal 30: Voltage too Low : P1602 :thumbdwn:

Can anyone help me with fixing this please

Oh also I have cleared the code and will check whether it comes back in a day or 2

I suspect you've just let the battery run a little low one day.

this comes up if you disconnect the battery.

Cheers guys I don't know how old the battery is so may swap it out for piece of mind with the cooler months coming. Just been out for a run and rescanned and no codes popped up but will check again next week some time.

Any advice on where to get a battery, Halfrauds want £90 for a standard lead battery and £100 for a calcium battery. Which is recommended?
