Volkswagen Golf Service & Repair Manual: Before operating the air conditioning system after recharging with refrigerant

After installing a new air conditioner compressor or filling with fresh refrigerant oil (e.g. after blowing out refrigerant circuit), turn compressor pulley 10 revolutions by hand before starting engine. This will prevent damage to the air conditioner compressor.
–  On 5-cyl. or 10-cyl. diesel engine, turn air conditioner compressor at overload protection 10 times by hand. Then install compressor. This will prevent damage to the air conditioner compressor.
