I wonder if the high speed driving could have damaged the HSD system? Has anyone else experienced this? I really dread taking this into the shop and have them try to fix it. I just don't know how much experience they have with HSD.
Is this the sound the special glass ($1000) windshield is suppose to suppress? Do you hear it with the windows rolled up and sunroof closed?
Can't say I hear ANY whine from mine even with the windows down.
