Boot opening/closing

[centurion]

i'm on a mission to close couple intermittent issues on my car and electric boot is currently on the agenda...

Issue:
- struggles to open up via keyfob. I can see that it pops up [by an inch or so] and then it cannot open up... few seconds later is shuts.
- i tried by going round the back and it does indeed work but needs some manual effort to lift off and it would then go all the way
- now closing is more of a problem... 8/10 times when el. button is selected just above the latch mechanism it does get a signal but fails to close.

i checked in VCDS for any issues and haven't found any... all hinges etc had been oiled using Lithium so i guess it could be down to the motor. Any suggestions?
