The E9X M3 DCT heat exchanger is part of the M3's two-stage transmission cooling system. The E90/E92/E93 M3 DCT heat exchanger is located at the top of the transmission, separate from the remote oil cooler located in the right front grille of the front spoiler. The heat exchanger is an oil to coolant system that operates when the transmission is cold and during slow movement (traffic) where the front oil to air remote cooler is ineffective.

A blocked heat exchanger will cause internal DCT temperatures to rise, hard or delayed shifting, limp mode and fault codes, or even complete transmission failure. If your E90, E92, or E93 M3 DCT is experiencing any of these symptoms do not automatically assume the transmission itself is at fault. Replace the heat exchanger, thermostat, and possibly the auxiliary coolant pump first. In some cases the heat exchanger is clogged and removing and cleaning it may restore its flow.

This is a Genuine BMW M3 DCT heat exchanger. It's the same part as originally installed on all E90, E92, and E93 M3 DCT transmissions so it will fit and operate just as the factory designed. It comes with a two year warranty. Coolant lines are sold separately. Refer to shaded blue component in image above (actual color is grey).
