hi folks , i have a 3.0d quatro a8 2005 with 170k miles
when i turn off the engine the compressor keeps running until it runs down the battery
when i hear it running i disconect the battery for a while (at least 30 mins) and it usually is ok when i repower
is there a simple solution ?? like a relay etc ???
brought it tomy local audi garage last week, they had it for 2 days and it didnt happen once
they said they found a few water damage connections and cleaned them (400 bucks)
2 days later....same problem
would greatly appreciate any info
many thanks in advance

 

Wait that doesn't really make sense . The compressor is powered by a pulley so when you turn the car off it shouldn't keep working. Unless you are talking about the blower which blows air into the car.

 

He means the air suspension compressor.

 

Likely a small leak in one of the hoses, and/or a sticky relay.

There are several threads on AW about it, but I don't recall seeing it posted about here.
