1992 500SEL, 2003 SL500
It might just be me but I spent an awful lot of time raising and lowering the roof on my 03 SL500. I mean a LOT. So much so, that my wife cautioned me, "You're going to wear that thing out". As with most things I ignored her warnings and then a few month's back it happened. The front latch for the roof blew a seal and my roof and door trim filled with hydraulic fluid. She is ALWAYS right . A little research online and a quick call to Skyland in NC had both the replacement trim and the latch headed my way. My trusty mechanic tackled the job and we had it back on the road in about 2 weeks. Unfortunately, my glee was short lived as top started to slow down to the point it would timeout before finishing its cycle. It usually stopped prior to the latching of the roof or the trunk closing completely. My SL has the Smart Top mod and as such I think it really proved to be a good indicator that I had some performance issues by not getting all the way open or all the way closed. Working on the web and in the forums I learned that Top Hydraulics up in the Northwest not only provided good information they had good pricing. This discovery led to about a 4 week effort to diagnose and repair my problem. I got a pump rebuilt but after testing Klaus at TH noted the pump was old but not really bad enough to cause the issues I had. From there we picked the most likely rams that needed overhaul and I dutifully had my tech remove them and we shipped them off for rebuild. If it had not been for the expert advice from Klaus and quick action on the part of my mechanic I might have missed the whole summer. As it turned out the team at TH took excellent care of me and my wallet.
