Hi there, when I try to unlock the door either with the key fob or the door switch, the door locks then immediately unlocks itself. I have looked into the cables between the doors for any breaks, but can't find any at all. and now, the fuel gauge is starting to play up as well, sometimes showing empty, but taking less than 30lts to fill or showing half a tank and running out and showing completely / being empty and when 20lts fuel put in then showing over half a tank. I know ppl joke about French electrics, but I'm starting to believe them...
