Problem didn't pop up as often after alternator change and it took around 2 weeks for it to disappear. Hope the problem won't appear again.

At first I thought cooler weather driving will be better but it made no difference to to problem. I'm guessing the alternator and battery is making all the sensors acting up
I had this on and off for a good couple of years. It has turned worse - so has the battery - so this is good input and another reason for me to get a new battery.

Thanks
