Recently, I've found the car will accelerate normally in 1st, 2nd and 3rd gears, but the clutch seems to slip when it selects 4th and 5th and to a lesser extent 6th gear. This can be interesting when trying to move into the space between two artics when joining a dual carriageway!
Apart from this clutch slip, the car drives nicely, no juddering or unpleasant noises from the gearbox or clutch. Is it worth getting the system re-calibrated by Mr Citroen, or is it simply new clutch time.... I know this will be costly!
