I have a really wierd issue and would appreciate any views! About the end of the initial lockdown my 6J Ibiza, which hadn't moved much for a while, started showing intermittent battery light on. I was unable to find any problem with the alternator or battery, voltages seemed fine. Eventually I decided to replace the battery which was the original, so getting old anyway. Sadly the issue returned. Very recently I realised that the battery light problem was somehow linked to the rear screen heater, the momentary switch controlling it was apparently inoperative and unlit whenever the battery light was on, and the red light went out about the time I would expect the timed heater to switch off (10 minutesish). Restart and switch press works normally for a short time but then the issue recurs, and the switch light goes out as the battery light comes on. Sometimes it has been days without any problem, and "working" the relay sometimes seems to help, when it is clicking normally.
I've ordered a replacement relay but wonder if I am barking up the wrong tree. it seems to me that the relay must be somehow leaking current but I don't know how that could happen without blowing the fuse (checked of course and looks perfect). Any ideas?? Thanks in anticipation.
