How much refrigerant does a BMW Z Series A/C system hold?

The 2014 to 2016 BMW Z Series (4 Cyl. 2.0 Eng.) holds 21 oz of R-134a as a complete system charge. That is the amount for an empty, evacuated system, not for a top-off.

Can I put R-134a in a car that uses R-1234yf?

No. The two use different service fittings on purpose and different oils. Charging the wrong refrigerant can damage the compressor and is illegal in the US under EPA rules.

Can I recharge the A/C myself?

A DIY can with a gauge can top off a slightly low R-134a system. If the system is empty it has a leak, and adding refrigerant without fixing it wastes the can. A full charge needs the system evacuated and weighed in, which is a shop job.

A system that is empty has a leak - fix it before charging.
