I have a problem with the soft top. It basically just stopped working. I have owned my R129 SL500 for about 15 years and I did have a problem about 10yrs and had the controller refurbed so thought it might be that but had it checked its fine. My friend but his diagnostic tool on it and this came up-soft top bow A23s2 limit switch locked R- I am not technically minded so if anyone can point me in right direction I would very much appreciate it. Thanks Shaun
