Hi Guys, Seems like many of you have a great deal of useful technical knowledge to spare. I have owned a 1990 300SL (129 UK delivery 12 valve ) for the past five years. For the most part it has given me a great deal of pleasure until my convertible roof started acting up last year. First all the hydraulic seals on the rams gave way, which after a great deal of difficulty i managed to replace through a long drawn out DIY repair.

Yesterday, after a couple of months of using the hardtop i decided to use the softop again, and to my dismay, the hood struggled to clim out of its compartment and stopped midway several times without completely closing, before finally stopping for good on about the 6th attempt. The Rollover bar does not move either now wheh i try to actuate it.

I have since closed the roof manually, and the warning light is off. When i use the convertible top swithch the light comes on, but all that happens is some clicking noises of solenoids in the back, but the pump doesnt seem to actuate to move anything. Hydraulic oil level in reservoir is adequate, and there are no leaks. Fuses are all OK as well.

Any suggestions? My local mechanic has suggested that the electronic roof controller unit may have packed it in?

Not sure if this is related, but last week prior to this, my dashboard was lit up like christmas lights apparently due to bad earthing somewhere in one of the door sensors, but is now fixed after a local electrician sorted it out.
