This TSB applies to 2004-2009 Audi A8, 2006-2009 A6 Avant and 2007-2009 Q7 vehicles equipped with Audi’s air suspension. DTC 01577 (compressor switch off due to excessive temperature/sporadic) may be stored in the air suspension control module.
The air suspension module will log this DTC each time the air suspension compressor is shut off due to excessive temperature. The compressor will resume normal function after a short cooldown period of 30 seconds to four minutes, but the DTC will remain logged in the air suspension control module.
Do not replace the air suspension compressor to address this condition.
