2006 Citroën Citroen c4 1.4

I sell a Citroën C4; the vehicle is in good condition and ready to drive. The servo steering system starts only after a short drive and the control light for the lambda probe lights (the lambda probe must be replaced). Apart from this, the car can be driven normally, and the defect does not affect the function. The sale is done without any warranty or withdrawal. The air conditioning must be filled.
