Dear all,
Of recent, when i have been driving at high speed and i park, i hear a loud sound like someone drilling coming from the rear. It goes on for like 30seconds.Like around the compressor area. I replaced this suspension air compressor 10months ago. Could it be the compressor or something else?

 

Simply get down and listen better, 30 seconds is plenty of time to figure out exactly where its coming from.

 

Its now weeks without that noise. I hope it disappears forever.
Otherwise, i will try to listen better if it comes on again.
