Screechy Sound on start up sometimes

[shaman1204]

Ugh! My '01 with 42K does the same thing when starting cold. I have a new serp belt that I was going to put on to see if that fixed the noise. Probably not! Just had the alternator and coolant overflow tank replaced (after leaving me stranded) and I just replaced the ignition switch yesterday, which is super easy BTW. It appears my car is molting one part at a time.

It was the ignition switch for me which caused the stater to clash for a short time. The switch travel started getting sloppy. It wanted to remain spring-loaded to the "first detent position", door bell remained on when key was removed, I had to push it to the off postion to remove.

On another note, beware of replacing the electrical portion of the ignition switch only. I read that some have had good luck with replacing just that part...not me.
I started out buying that part from autozone (previous threads) and it wound up being the mechanical portion of the assembly in front of it. I couldn't get it started, had to have it towed to Porsche (thought I activated the immobilizer) and Porsche stated the mechanical portion prevented the key from reaching the full travel to activate the starter. $277 later all is ok. Porsche asked how I was able to just buy the electrical part since they only can get the whole assembly. Their experience is that it is always the assembly that causes the issues.
btw, it took them 3.5 hours to remove.
