Hey all,

2015 Silverado HD. I've got a beep or a "fax machine tone" coming from the engine compartment when the truck is off. Sometimes I'll hear it when I'm near the truck so I will try to find it and of course it stops when I get close. Any ideas?

If your truck is still stock (no emissions deletes etc.) it's your EGR module running a self-clean process after every shutdown. ?
