This BMW AC expansion valve (OEM 6823978) is a genuine used part, removed from a donor vehicle. It meters refrigerant flow into the evaporator, critical for proper cabin cooling. When the expansion valve fails, you may notice weak or intermittent A/C performance, or no cold air at all. This particular unit came from a BMW X3 or X4 fitted with either a 2.0L four-cylinder (diesel or gas) or the 3.0L turbocharged six-cylinder.
