Air Conditioning Upgrade

[Peter Golledge]

Similar to that described for the A4.

Flush the system out, new o-rings on fitting, new 134A compat oil, new dryer and orifice tube. Evacuate and fill.  BTDT with multiple type 44 systems.  As Tony said, mostly labour the parts are relatively cheap.  Orifice tube is literally $5.  However you do need a vacuum pump, gauges and time.
