Figment

I'm having a similar issue with the rear washer (fronts work fine) A few months ago the fluid would only dribble out of the rear jets. Cleared them with a needle and all worked fine again. Now they've stopped spraying again although I can hear the pump working. Tried clearing jets with needle and also with a thin wire. Nothing. Removed jet assembly (they are clear when blowing into them), and tested washers with the jets disconnected and there's no fluid coming out of the connector pipe. Pushed a length of wire into the connector as far as it would go (about 4 inches) with no joy so I'm guessing there must be a blockage / air-lock somewhere between the pump and where it connects to the rear wiper motor or could it be something more complicated? Where do I start looking? How does the tube detach from the back of the wiper motor? Would a burst of compressed air down the connector thejets attach to help?

@varooom Could I impose upon you for help with a firmware upgrade please? Image attached with current version. Thanks in advance.

I'm thinking of retrofitting a tailgate release button (pictured) on the right of the gear lever in a 2010 Superb II elegance. Does anyone know if the plug/wiring is already present (and where would I find it), or would I need a separate loom? Thanks in advance.
