Anyone ever have an intermittent loud squealing noise on the 4 series? Know noises are hard to troubleshoot on a forum but guess asking a general question. Figured I would throw it up here before heading out to this far away account. Customer sent me a video from phone, tried to attach but didn't work, must be too big of file. Never heard anything like it on all the 4 series I've worked on.
Any ideas on how to attach video so you can hear it?
Thanks in advance
