The aircon system in my 1990 560 SEC has a tiny leak. A dye test confirms that it isn't anywhere in the engine bay. A sniffer test suggests the leak is somewhere in the circuits below/behind the dash panel, in the driver's side footwell (NB the left side - I have an LHD euro-spec car).
Dismantling the dash is a daunting prospect. The leak is more likely to be at a joint - eg around the expansion valve - than in a system component. But where do the hoses run and where exactly is the valve located? Can anyone advise, or point me to good pics/diagrams, which explain what panels or fittings to remove in order to see and check the hoses and connections?
