Click on "here" at the bottom of this page to see some examples of vehicle type specific tips, the diagnostic section and the filling tables.

With just a few clicks of the mouse, the diagnostic section enables you to read the possible causes of pressure/temperature related disturbances in the auto aircon system. The section discerns between systems with fixed displacement-, variable displacement- and externally controlled compressors on one side and expansion valve or orifice tube on the other. Combined with different types of possible pressure- temperature combinations which may indicate a disturbance in the system, the section offers to chose from over 60 different configurations. From May 2015 the website will be added with a new section with over 5000 wiring diagrammes for Europe's  car a/c systems. Contact us for more information! 

Please be aware that service to auto aircon systems requires sufficient technical training and experience. The information on this website is therefore no replacement for the required training level and strictly serves to provide additional experience-based information.
