n52 grinding noise
I recently purchased a 2011 E92 328i with its valve cover gasket and spark plugs recently changed. The car has 250,000 km and runs fine, other than a grinding sound that occurs only at idle. The sound disappears after 1k rpms and doesn't seem to affect driving at all. There are no cels or leaks. The only potential cause I can predict is that it may have something to do with the AC compressor, which may be on its way out. Do you have any idea what this sound could mean?
