Servus, Hab hier eine 97er (MOPF 1) SL 270 von nem Technisch nicht gesonderlich Versierten Freunden, der an Erektionsschwacht, i.e. the Benz not the known 🙂 !!! The top works perfectly up to half and then it’s over. The window lifters funk in the automatic impeccable and the roll bar is also functional without any faults. The control unit has already been repaired and also found by Mercedes in Vienna as impeccable. Hydraulic fluid is new and it All of them have already been executed and checked by the friendly. Battery is new and fully charged. To the symptoms… When the switch is activated, the whole process is completely normal until the top is about vertical and then there is no more. Close goes on here. The blinking out has probably resulted in “some mistake in the hydraulics”. Now good advice is expensive, if you look at the prices. Since no oil loss or leakage is to be determined. I don’t know now either. In my opinion, the next step is simply not initiated here and as far as I know there are no electrical limit switches integrated here or am I mistaken ??? Could it actually lie on the cylinders or rather on the valves ? Can I check it. Would be very grateful about tips and field help
