Hi,
If you havn’t driven it much or far recently the battery might just need charging up. If this is not the case, get the battery checked and replace if knackered. check the terminals and clamps are clean and tight.
Also, as @3000gt will testify sometimes even good batteries stop after a few days, I know mine does. Am in the process of putting an ampclamp on the positive lead to see where the draw is.
I’m gonna get a new battery tomorrow and see if I can get it sorted. Just so I know what I’m dealing with when I manually unlock the car and open the door to pop the bonnet the alarm will go off (I am pretty sure of this) is there any way I can shut it up ?
Also when the car is running, check the battery voltage with a mutlimeter, 14 volts means the alternator is charging the battery. In the past with my cars, a failing alternator fits the description of your problems in my experience.
You can’t beat this price delivered for a varta e24 blue came next day ordered same as one I’ve just took off, don’t line the pockets of mitsubishi etc there are loads of batteries to choose from.
Yes I think I need to do this as @stevie was saying plus the more I do the more I want it to stay clean so the less I drive it which wasn’t my original plan but the bug has got its grip.
I just went with it again as have always used varta ones never let me down plus I literally just covered the battery in red perspex the size of the e24 and it went lol
Tanya on Ebay sell the 069 battery for £47, free next day delivery if ordered by 4pm and a 4 year warranty. All my cars now have these batteries and I have never had a problem. Brand name of battery is powerline.
