Weird Startup noise!?

E82dude1 · 02-19-2025, 09:13 AM

Hello,

2011 N55 DCT 135i, only on first startup in the mornings I get this weird scratching noise right during startup, it has only happened in the mornings (only time it is "cool" here in AZ!) I have never heard it any other time, only lasts a second or two. No codes, no issues, just curious what this is or if anyone else has encountered it?
