ARNOTT P2985

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 of 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.

Air Compressor failure is typically the result of a leak or other issue in the air suspension system. To ensure that your new compressor will work without issue, you should do the following, prior to installation:

• Check for blown fuses and ensure the relay is working properly. A failed Air Suspension Compressor Relay is a top cause of air compressor failure. They normally fail in the “closed” position and should be replaced during compressor installation
• Check and replace the Air Springs if they are showing signs of cracks, deterioration, moisture, or are leaking. Complete Air Strut assemblies, which include the Mount and Air Spring, can be found in the Strut category
• Verify that the air line and wiring harnesses are connected without signs of physical damage
• Ensure that the fittings and valve connections are fully seated and undamaged. Make sure that the air line is secured at the proper depth
• Check the electrical connections and the orientation of the Ride Height Sensor arms
• Check all Air Suspension Solenoid connections and fittings; inspect for any cracks or other damage
• Inspect the air lines for kinks, holes or other damage

If you like the load-leveling capabilities, or if you tow with your vehicle, then you should repair the original air suspension system.

If not, and you are tired of the high cost of replacing air suspension components, conversion components can be found for most vehicles under the Coil Spring, Strut / Coil Spring / Mount Assembly and/or Suspension Conversion Kit categories, in the RockAuto catalog, depending on the vehicle setup.
