Guide to R134a Compressor Compatibility

The survivability of a given compressor when retrofitted to R134a has been heatedly discussed for several years.

VW Jetta, Golf, New Beetle 1.9L TDi Unichip PnP Installation Instructions

Although the PnP kits and ECU’s are identical, the New Beetle’s EC’s location is different than the Jetta/Golf; therefore these instructions are split – the first section describes Golf/Jetta installation and the second section describes Beetle installation.
(2) The ECU connectors lock and unlock by pulling the “T-handle” located at the connector’s edge. Look at the locking handles on the PnP harness and familiarize yourself with the mechanism before trying to remove the OEM plugs.
(3) When trying to remove the OEM Plugs from the ECU, getting your fingers into the T-handles can be difficult. You can gently pry the T-handles back using a screw driver.
(4) The Golf/Jetta OEM ECU bracket will not reinstall with the Unichip PnP harness in place without modification. You can easily modify your bracket as outlined below or can by a modified bracket from UNA (UNA Part # 9950001).

1996 Volkswagen Golf A/C-Heater System Manual

Evaporator Temperature Switch
Although compressor clutch does not normally cycle on and off, an evaporator temperature switch turns off the compressor clutch if evaporator temperature decreases to 32øF (0øC). This prevents evaporator icing.

A/C Pressure Switch
A/C pressure switch is a triple-pressure switch, which monitors high side pressure. See Fig. 1. If pressure decreases to less than 17.4 psi (1.2 kg/cmý), A/C pressure switch interrupts power to compressor clutch (low-pressure cutout). Switch closes when pressure increases to more than 34.8 psi (2.4 kg/cmý).
