nas1924 Posted August 24, 2004 Report Share Posted August 24, 2004 i recently purchased an audi a4 1.8i(20v), noise seems to be coming from climate control mechanism. Its a mechanical noise quite load -whining/grinding noise. Interesting thing is when you switch on the ac the noise dissapears, any clues to what it is? My mechanic(who rips many off)says its coming form ac pump/compressor, nothing to worry about but can be changed. any ideas?? Link to comment Share on other sites More sharing options...
eolair Posted August 25, 2004 Report Share Posted August 25, 2004 I've a 1.9 tdi, and it suffered excessive vibration and some noise, that stopped when the a/c was switched on. Turned out to be the injectors, which had to be replaced. If you do a seach, a couple of others have had a/c noises, that were solved by replacing the a/c unit.
