BMW reviews parts pricing every month. Some of the increases are reasonable some don't seem to make any sense. I've seen as much as 100% increase from month to month. Part of the reason is the age of our vehicles which decreases the volume demand. Lower volume runs of parts increases the costs substantially. SOP is to increase price of all stock, parts already at the dealers, based on the cost of the short restocking runs.
