Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Servicing Station, Connecting For Measuring And Testing
- Work procedure may vary depending on the type of tools selected (the tool-specific operating instructions should therefore be followed).
The work procedure is always to be performed as described in the operating instructions for the A/C service station -ROB 134APF- (or subsequent models).
The charging hoses are to be connected as follows to prevent the entry of air or moisture into the refrigerant circuit:
-- Switch off the ignition.
-- Connect service station to power supply.
-- Connect quick-release coupling adapter to charging hoses of service station (hand wheels not screwed in/hand shut-off valve not open).
-- Switch on service station and evacuate charging hoses (only necessary if there is air in charging hoses).
-- Switch off service station.
-- Remove sealing caps from service connections or connections with valve (see vehicle-specific refrigerant circuit).
Refer to [For engine(s) BGP, BPY, BGQ, CBTA, CBUA, CCTA, CBFA] Removal and Installation .
