Hi guys,
I have a 97 A4 with 50000 miles on the clock. About 6 months ago I get in it without driving it for a couple of weeks and nothing - I notice the central locking is sluggish and the volts are very low.
So I get a jump start, get on my way and forget about it. problem never reoccurs until .... a few days ago.
Again same symptoms. Again a jump start works ok and I drive it and park for about 5 hours, get in and no problems.
Then yesterday I get in and again it is low on volts.
I have checked and there are no lights on, no stereo, accessory (phone charger) unplugged.
So I am at a loss.
Would a "bad battery" behave like this = fail, work ok for months, fail, work for days, fail again?
If not I presume I have an electrical problem.
Something I have had for a long time is that the light behind the heater control (to illuminate in the dark) is sometimes on and sometimes off. Then a week or so ago for a few days the electric sunroof started playing up - opening and closing without me touching the control and not shutting when I moved the control to the shut position - I needed to move the control beyond that position.
Don't know if any things are linked.
I have now purchased a jump start pack and am off fishing for 24 hours in a remote place. Intend to return to the car every 4 hours and run the engine for 5 mins - I hope this will keep things ok - what do you guys think.
ANY advice would be gratefully received.
Thanks
Ed
