just a note to say ive just collected my ds4 from the dealers and the steering is not centered ... how can they miss not seeing this ??? ive owned 6 citroens over the years and this is the first like this ...... ive now covered 400 miles from new...... im waiting for side rubbing strips from france the dealers will sort problems when they arrive...... is there a back light on the radio on / off knob ???? its the only one not lite up ????
