Loud 'banging' Noises From S Max Speakers
Posted 24 October 2011 - 06:05 PM
My wife's S Max has suffered from a strange problem recently. When left parked, with the doors closed and either locked or not, the speakers will suddenly start 'banging' (that's her description, I would say its more like the crackling noise speakers make when you touch the two wires together). This happens more on a hot day in summer, but we can hear them at night too. Usually the nse stops when you open the door - this makes me wonder if it's the radio because the radio wakes up ( the clock lights up) when the doors are opened.
We also had the usual Alarm problem, I took the fuse out but never had it repaired - who ever responds to a car alarm nowadays anyway?
It's a 2l diesel, no Sat Nav, three button Air Con.
Anyone know a fix?

We also had the wipers coming on and the alarm false tripping.
They said that this backup battery is another known problem along with the alarm sensor.
