Compressor, removing from bracket and reinstalling
Note. Do not unfasten refrigerant lines and corresponding clamps. This illustration shows compressor for 8-cyl. MPI engine. For the other engine versions, allocation differs only slightly from this (e.g. different refrigerant lines). --> 13 - ENGINE - CRANKSHAFT, CYLINDER BLOCK Depending on version of vehicle, it may be necessary to push aside or disconnect individual hose lines that are routed in the vicinity of the compressor.
- Remove noise insulation --> «63 - BUMPERS»(/audi/a8/d3-2005-2007/remont/door-locks-anti-theft-systems/#body-exterior) .
- Bring lock carrier into service position --> «50 - BODY - FRONT»(/audi/a8/d3-2005-2007/remont/door-locks-anti-theft-systems/#body-exterior)
- Mark connector to A/C Compressor Regulator Valve N280 because of danger of interchanging with connector to electric engine mount.
Note. If connectors to A/C Compressor Regulator Valve N280 and to electric engine mount are interchanged, no DTC is entered in DTC memory, however the evaporator may ice-up since the compressor is actuated continuously.
- Disconnect electrical connection to A/C Compressor Regulator Valve N280 at harness connector.

- Remove bolts - A - (25 Nm).
Note. Install one washer each - B - at bolts - A -. Before fastening compressor, check both bushings - C - in bracket or compressor for correct seating. After fastening compressor, check installation position of refrigerant lines - D - and - E - , lines must be engaged in brackets provided (if installed, depending on engine). After attaching compressor, also check refrigerant lines and corresponding holders for adequate clearance with respect to other components, ensuring sufficient distance between belt, holder and pulley.
