Ive been to see my AA mate tonight who tested the battery. It came out ok saying it just needs a charge so Im going to leave it running for a few days over the weekend.
He did however find a fault
Front Central electr. 4.0
030482 Heated steering wheel short circuit
We cleared the fault codes but its till not working. After I've given it a charge ill pop the airbag out to make sure Ive not caught any wires that may have rubbed since the replacement steering wheel was fitted. Either that or my heating coil is buggered
