megane phase1 2,0l cabrio / cursed cover

hello people, drive a megane 2.0 liter 16v cabrio (phase 1) the cover no longer opens completely. the cover box rises up, but does not open. it beeps 6 times! I have already done: the shovel wheel changed, closing motor removed and the closing mechanism tested by hand (manual), closing motor driven in output position (by battery on the plug on red and black cable) and peniebel cleaned/lubricated, hydraulic fluid filled. before these measures: pip my cover immediately 6 times when I operated the switch. after these measures: beeps only 6 times when the back flap opens and doesn’t drive any more!!! have it already learned 1000 times, after a good description from the internet!http://www.scriptkiller.de/en/a6/renault…it_dem_verdeck/ how can you vent the bullet? that would be what I thought of, or are there other things where I can put it???? is really in despair and pretty slowly forget Eht me really the joy! would be grateful for any help mfg niko
