Original BMW Automatic Air Conditioning Control Unit for BMW X5 E53 (2000–2005)

Built for the 2000–2005 BMW X5 E53, Original BMW part 64-11-6-927-900 is the automatic air conditioning control unit that manages cabin heating and cooling on X5s with automatic climate control. On an automatic system, the control unit takes the driver's temperature and fan settings and commands the rest of the heating and air conditioning system to hold them. BMW names it the automatic air conditioning control and sells it as one piece. This number is matched to a specific equipment combination, so the options on your X5 matter as much as its model year.

Original BMW Parts carry a 24-month parts warranty.

BMW began production of this number in September 2003. Numbers 64-11-6-916-648, 64-11-6-915-810, and 64-11-6-902-560 also cross-reference to it as OE numbers. BMW's parts data shows it on the E53 X5 3.0i with the M54 engine, the 4.4i and 4.8is with the N62, and the 3.0d with the M57 and M57N.

Common Questions

What points to a failing climate control unit?
An air conditioning system that can no longer be controlled can come from a defective control unit. These units are known to fail with age, which causes a range of problems with how the air conditioning works.

Can this replace part number 64-11-6-926-882?
Yes. BMW marks this number exchangeable retrospectively with 64-11-6-926-882, so it is the correct replacement on X5s that came with the earlier control unit.

Will it work in an X5 without rear air conditioning?
BMW matches this unit to X5s with automatic air conditioning plus rear air conditioning, so an X5 without option S533A is outside its coverage.
