Hi everyone,
My roof was not going up as one of my roof hydraulic cylinder was leaking, to confirm it I filled some Porsche transmission oil in reservoir & now roof was going up.i operated it successfully 5-6 timea. So I ordered new cylinder & replaced it & filled correct oil..
Now I tried to close the roof it closed properly & latch is locking but it is not opening now, fault appears as " roof limit not reached & roof fault" in cluster. Now everytime I tried to open/ close with switch fault is appearing but it is neither opening more closing & motor is not working. I got a tester from my friend tried to calibrate it & during calibration motor works but latch is not opening, now if I try to manually open the latch & lift roof a bit, than try to calibrate the system, it closes & latch closes the roof properly,but not opening & calibration becoming unsuccessful....
any idea what may be wrong ?
Thanks

Hopefully it may help someone... I found the problem. At the left side of car, there is a potentiometer next to hydraulic cylinder, which was not working fine & one of microswitch at roof console was bad..
fixed these two, problem gone.
