Arnott Air Suspension Products made the installation of the air suspension compressor for the 1999 through 2005 Audi Allroad Quattro and Audi A6 Quattro (C5 Chassis) a simple “Plug & Play” operation by including a new wiring harness with thermal resistor and relay.
The compressor, manufactured by WABCO, replaces OE P/N 4Z7616007A. The Arnott P/N remains P-2134, and it retails for $505.05. The part is backed by Arnott’s limited two-year warranty. P-2134 is the same air compressor used by Audi, and includes a dryer and new airline fittings, plus powder-coated mounting brackets. Unlike the previous version, the pump now includes a relay and new wiring harness with thermal resistor for a faster installation.
A detailed installation manual and updated installation video are also available.
