Can anyone help me. I have just bought an 04 Pluriel and can't adjust the seat. I can make it go up and down, backwards and forwards but cannot adjust the angle of the seat. I pull the lever to my left and it just moves it forward then sets back at the original angle again. I feel like I'm half lying down when driving. Is this how it is with all pluriels or can I get it fixed at the garage. Help,my back is bloody killing and I can't see over the steering wheel!
