My car is 2002, but only 19500 on the clock; it was my mum's which I inherited (she didn't drive for the last 3 years, hence the low mileage). Anyway, the roof leaked so I raised it half way and applied lots of silcone lubricant but then the roof wouldn't work. Tired and tried but no avail. Eventually managed to get the roof into the open position.
I only managed to fix the roof thanks to this video www peugeot206cc co uk/viewtopic.php?f=5&t=15173#p120111
So I strongly suggest you look at this video if you have problems - I managed to get the roof into the closed position manually and then it reset. I'm so pleased!!
ps - the car's not really a use in the wet car - due to the water feature of rain dripping into the car if the front windows are down

Silver Peugeot 206 CC 2002.
