Non-S engine startup screech
Hi everyone: I have an 09 justa.. sometimes when it's been cold and I start him up, i get a screech from the engine. very mechanical, almost grinding sound. It's briefs, 1 second, and it's not all the same tone/volume.
Any one else have this sound on start up? It can't be the timing chain noise since I don't have the S...??

Things like this should really be posted in the "Stock Problems/Issues" forum; it would probably get more attention (and therefore, answers) there.
That being said, wild guess here: based on your description of the noise (momentary at start-up), I'm thinking the starter isn't fully disengaging when the engine turns over. I would start by checking that.
Next thing I'm thinking is one of the pumps (e.g., water) isn't fully primed at start-up; sometimes when things like that occur, they will make screeching noises.
Good luck!

I have the same sound on the 2010 non S. Had dealer hear it and they blew it off, Said it was normal for 2010 but the loaner was a 2010 and it was quiet. I thinks its the starter not disengaging. Louder and longer when started first time after long time shutdown. Seems to be getting worst. Car has just turn 2k.
