2014 Estate, 95K miles, owned by me from new, but KESS system getting erratic, so asking for some advice please.
The key fobs were both given new batteries 9 months ago.
The keyless unlock/lock has worked faultlessly from new until a week ago.
The car always locks/unlocks on the key fob buttons, but:
Sometimes the touch to open will not work, (both doors), unlock button works.
A few moments or minutes later the touch to lock will not work (both doors), lock button works.
Sometimes everything works!
When working, the touch commands will work in quick succession if I touch the right spots correctly.
I feel the touch sensors on the two front door handles are working, but i also think the sensor that picks the touch up and fires the whole system is intermittent quite suddenly from working 100% to less than 10%.
I guess the touch and button signals are not the same circuits?
Is there a control unit for this or is it all part of the security/alarm etc system. I presume the button sensor is in the rear view mirror housing?
I'm worried the key fob will start to fail too.
Any comments please as to an explanation and of course a fix!
Might have found the issue just. The fob that is never used (but had it's battery changed same time as the most used fob) seems to work buy the KESSY touch 100%.
As it has just sat in the draw since the new battery I presume the battery is stronger than the well used fob.
It will work by touch when the used fob fails to respond to touch.
Will change the battery in the well used fob. I have tried the 'life-time' batteries at Timpsons and they failed in months, the batteries SKODA dealership uses are much better.
