The first thing to check on an mp9 when the consumption goes up, is the 4-pin water temperature sensor.

Have you recently changed anything ? (Wheels/Mags/Air filter)

Changed your driving style or route ?

What did you get before 12km/l was it messured over a full tank ?

The CSL is a BIG car with a smallish 1.6 motor so your not going to get great consumption at the best of times...
