Peugeot 308 warning lights

Got my car washed one evening , that night I parked uo the kerb and all the warning lights popped on , brakes , hill start , esp , a whole load of them , when I turn the car off they all reset and the xar is grand , I know if I go io the kerb that all the lights will come , car is currently in the work shop and it's gone Into limp mode after timming belt and water pump , only fault showing is crank shift sensor , has any one experienced any thing like this
