Arnott's new replacement air compressor P-2985 is from WABCO - the original equipment supplier to BMW. Unlike compressors that are simply modified to fit the vehicle, this compressor was designed by WABCO specifically for the BMW 5 Series F07 Grand Tourismo (fastback) and F11 Touring (wagon) incorporating a high level integration mechatronics. This high-performance, yet quiet, WABCO compressor includes a maintenance-free integrated air dryer and comes completely assembled from the WABCO factory in Germany with an application specific air line and wiring harness. This direct replacement compressor comes in a WABCO box and is ready to install into the factory mounting bracket.
