I also get a weird sound on especially cold mornings that sounds like a squeaking pulley of some sort. It wouldn’t surprise me if my car needed a new alternator and new pulleys. Does anyone which pulleys those are specifically? My 09 has never these parts replaced AFAIK.

I also have an intermittent P0300 that will show up in my ecutek app but will disappear after a couple drive cycles, rarely showing on the dash.

I have the same sound on cold weather so I changed the pulleys, but the squeaking on start still remains.
