On my R230, the right side varioroof flap has developed somewhat of a play - no longer stays tight in the folded position. The play motion, though, is small enough that the limit switch remains OK actuated. This condition bothers me however because the end position of the flap with open roof ends up a bit misaligned - this condition is likely to worsen over time. Upon disassembling and observing, I noticed the small pinion gear coaxial to the flap hinge axis is missing a tooth, subsequently failing to tighly hold the small rack - just in the folded position - hence the play in the flap. I went to get a spare part, but you need to buy the whole assembly including motor, cables, both LH and RH end gears and flap support frames. It is over 500 quid! (... just for a broken tooth...) Anyone has any suggestions or happens to have this spare element? (ideally the end hinged support frame including the small pinion gear). Many thanks in advanced to all R230 mates !
