C1109-00 code - no CEL tho

Cory Gillmore

Kinda…I do have Z1 SS lines and 600 Motul but I didn’t throw this code until about 5 months afterwards. It happed on a cold start one morning where it seemed like it struggled to start like it had low battery power. 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.
