Quick release connectors on susp compressor
 

Hi,

I want to bench-test my suspension compressor (2003 turbo). I can't get the pipes lose that connect the compressor to the dryer (quickreleases). Any tips here?

Also for bench-testing: Which wire is POS (red/white?) and which is NEG (brown?).

Many thanks,

Maarten

Brown is usually ground.
Red/white is positive.

Not sure if the host sells them here, but Bentley may have a manual on DVD,
got one for my Touareg (aka the money-pit), also a Rosstech OBDII cable and app come in handy
