Nov 17, 2017 · I just got a C4 picasso diesel 1.6 from a trusted source the car has been with them since new and it has never had a problem. Not sure if it is "grand" or not. The car had a major service by citroen just a couple of weeks ago, filled it up this morning from sainsbury's full tank fill up 45 litres (nothing unusual there) it then drove to work
