Gotten deep into this problem. Now there is 2 Fix METHOD 1 - Minor Adjustment at the Catch Mechanism. The turning of the extension rod method is for Fine tuning only as contributed by one of the members. METHOD 2 - Major Adjustment at the Rear Wind screen Arm. 1) The roof is made of of 2 pieces, top and back (Windscreen) 2) open your roof half way so that it look like number "7" from the side. 3) Remove the plastic inner panel from the rear windscreen, Top, Left & Right. they snap off easily. 4) IMPT - look closely to the metal arm that connect the top and bottom roof, you will see a Black notch, it is actually a Cap Screw with a black screw cap. the entire screw is bolt into the Roof Mechanical Arm on a side bracket with another Nut in its screw to acting as a lock nut. IF YOU FOUND IT follow these instruction. a) remove the black cap, use a Allen Key to turn the screw, 1 to 1.5 round counter-clock wise (This is to make the Screw toward you so that it become longer. Do the same for both left and right. b) Close the roof and you will realise now that the roof will not close completely, leaving maybe 10mm gap. Hook the latch and you will see that the roof snap toward your front windscreen and the Latch now should be tight and good. if you cannot latch on because its too far, adjust the screw inwards and the roof should close closer to the windscreen now. c) Repeat method 2 until you get the sweet tightness you required. turn the Screw in or out half round by half round, test drive a few times to get this the tuning right (Observe the noise when passing harm or bumpy road. Make sure the gap from left to right is consistent. d) Lastly use METHOD 1 to do your final finish on how stiff you like your latch to be. Cover back the Screw Cap Cover, tighten the Lock Nut and cover back the plastic inner panel. e) Go for a bumpy ride to feel your brand new roof noise free.
