Is it the battery or something more major?
Not sure if this is the right place to ask this question. Please move the thread if need to.
Just a quick background info on my car:
2004 Mini Cooper
just over 100,000km+
approx 3 year old battery
installed warm white light bulbs for head lights, led light bulbs for parking lights
recently upgraded radio head unit with BT
only gets driven 3-4 times a week, short distance to work (45km per return trip)
After the radio HU upgrade which I did myself, I noticed my car doesn't start in the morning on 1st attempt. But it starts smoothly on the 2nd attempt.
This only happens the first thing in the morning, meaning when I leave work, it'll start straight away.
However, late last week it began to fail to start until 2nd attempt when I leave work too. So, I'm thinking maybe the battery needs replacing. Any other thought?
