Wow you have documented your problem well. My 96 Audi has similar
except is hash sound. Most noticable
arriving home listening to 1080, audio is half buried in noise till I
kill the engine, then audio is clear.
Everywhere one looks, the AM band just gets dumped on. As compensation
you would at least think,
they would put in HD radios so one could get the sister FM station relay
of the AM side. Wouldn't
generally help in the country of course... You could try a super duper
(ugly) AM antenna with coil, etc and
maybe a separate radio that's not hooked up to every modern doodad in
the car (ugly). Or... stream
internet (ugly sound and ugly just thinking about it.) How about,
record what you like from home and
listen on a day delay basis... or just listen to the podcast of: noagendashow.com

Has any one encountered the following problem?
With the engine running (either at idle or at higher rpm):
*Intrusive radio frequency interference seriously compromises effective reception on AM stations that are on 20 KHz boundaries, ex: 540, 560, 580, 600, 620, etc. all the way up to 1700.
*The interference takes the form of an audible tone.
*The tone sounds like an irregular pattern of pulses. The gaps between pulses are very brief, perhaps 100 milliseconds each. There are no long-time gaps between pulses.
*The tone does not vary with engine speed.
*The interference does not occur at any of the intermediate frequencies: e.g. 530, 550, 570, 590, 610, etc, on up to 1710.
*The intensity of the tone vs., radio signal is dramatic at some frequencies more than others, e.g.660 and 740
*The pitch of the tone increases as you move up the band, (1600 and above).
Dealer tech verified problem, agrees RFI interferes with effective reception; dealer tech found same problem in a similar 2015 Jetta; dealer tech contacted VWoA support center to determine if there was a fix or service bulletin for this problem.
Since the problem occurs in another 2015 Jetta similar to mine, VWoA support center says this is normal and my vehicle is operating as designed.
