2002 A6 2.7t a/c issues

[Aktung]

Hi All,
Just bought a 02' A6 that has an issue with the ac...the compressor will kick on for about 10-15 seconds, the air will blow cold and then shut off. I checked the high pressure side with a gauge and the pressures drops to within spec once the compressor kicks in, so it doesn't have too much or to little freon in the system. I pulled the code with vag-com and it pulled a 01188 -Electrical connection between Control module and Magnetic Clutch 57-00 Electric circuit failure.
Could this be the the high pressure switch? Any ideas?
Thanks in advance!

The pressure switch typically manifests a different error, at least on mine it did. Yours sounds like a wiring issue.
