WARNING: This page is about a different car, the 2010 BMW X3, 2009 BMW X3, 2008 BMW X3, and 2007 BMW X3. However, it is still accessible from the selected car via links, so may be relevant.
The drier bottle or drier insert does not have to be replaced at regular service intervals in a functioning, leakproof A/C system.
However, the drier bottle or drier insert must be replaced without fail in the event of:
- fouling of the refrigerant by filings/shavings (e.g. when the compressor is clamped)
- a leaking A/C system or loss of refrigerant
- the refrigerant circuit being opened for a period exceeding 24 hours, e.g. during repair work.
