Car electrics, when drivers door open, no keys in ignition battery light comes on, on dashboard eco mode appears, the engine management light came on.
Too be honest I think this vehicle needs a full diagnostic check but cant afford at the moment. Engine management came on once fitted new battery.
Also the radio comes on on its own. Also when using electric windows it makes the oil light flash on and off and also the the same with the heater blower does if you move the dial from 0 to 4 it will make the oil light flash on and off. Please can you assist me with this problem.
