Hi folk's, just thought I'd share this random behaviour from Monday evening to Wednesday  lunchtime , both plips stopped opening/closing our A6 C6 Avant also the boot courtesy lights stopped working , not sure of the significance?  Anyway tried the usual key in the drivers door holding open or close button down while opening and closing car with key ( the old way) " you all remember that right"!!  , also key in ignition to 1st setting and pressing plip. Both these ways  would reset plips to lock and unlock ! Walk away , come back and they stopped working again??? Then.... this lunchtime by god it all starts working with no help.Random ?? Anyone else experienced this and would it be related to this spike in hot weather?? Never had this before in 11 yrs of Ford Mondingo and Vauxhall ownership? ?.

It could be temperature related....I returned to my car the other day, got in and immediately jumped back out! 

The interior temperature was off the scale so could quite possibly be extremely high temperatures causing a glitch

Hi Trevor , yes I guessed it maybe however we have left windows partially open to help vent some of this recent temp hike. I've read somewhere that the transmitter receiver is in the boot behind one of the side panels in our Avant. Not sure this is correct though?? Either way it's decided to work so happy days , still odd !!😉
