Kat and fun2drive,

So I had a top that was intermittently stopping in the middle of the cycle, but only once or twice a year and only if the top hadn/t been used for a long time ie. winter. The last month it got more and more problematic. Finally two weeks ago in the up position it would disconnect all the sections and would not stack. Before that I had read this sticky on lubrication and followed it hopeing that was the problem, no dice. Mine is an 2007 with 25K miles and maybe 40-50 total retracts.

So took it to Seattle BMW and ithe problem ended up being the relay that controls the power to the hydralic pump. That explains the symtoms, with relay contacts slowly burning out. It was 4 hours of labor to take the trunk apart to get at the relays. They were real nice and only charged me for 3 hours and I walked out only $500 poorer. Hopefully this is not a sign of things to come.
