2004 NB 2.0L Convertible top issues
Been having issues with this for a while, but now escalated a bit.
For about a yr now, I have not been getting full top down indication, and the flaps that open to let mechanism go into and out of the side panel would not close. Not really a big deal, as it still went up/down.
But approx 2 months ago, it is not showing full up when closed and the indicator light on the top of the windshield shows the top is still en even when latched.
I know there are sensors in the side panel that sense when the top is all the way down and due to their position they get dirty and don't send that down signal correctly. If I could figure out how to get the rear side panels off, I could clean them.
But the bigger issue to me is the non-indication of the top being fully up/closed, as it gives the constant annoying chime/beep whenever moving from a full stop, then the constant flashing and not showing the outside temp.
So, Can anyone tell me
1) how to get the rear side panels out and clean the sensors?
2) Ideas on what may be causing the "not closed/full up" indication?
3) Any fuses/relays related to the ragtop operations an/or sensor indications.
Thanks in advance,

Failed switches/sensors; seem to be common issue, for the convertible top problems. Having a VW specific scan tool; would help, identify which switch is failing or possibly, needs replaced. The VW specific trouble codes; will give you the identification number of the switch and then you can go from there. As noted before; on the low end the vs450/vag405 are basic code readers, the vag 401 does coding, live data, higher end features (look on amazon.com for these hand held scan tools) and then, there is the Ross Tech VCDS which is close to the factory level scan tool (requires a windows based pc to run: combo of a cable/software). I am sure; the convertible top experts will chime in soon and give you some direction. :)

As for interior disassembly instructions; you might look up the service manual here: (this is for a 2006 but it may be similar to your 2004):
