nah, quite often I start with car in gear and you have to depress clutch to start anyway...if clutch weren't fully releasing wouldn't the car try to move as well?
but, all in all, I am glad to hear these responses, as it seems that it's not just me, or the car... yay

Since day one I got the car, the clutch in this C4S is very stiff. I call it heavy because it takes effort to push and I have had it looked at and it's fine. I guess it's a 4S thing, AWD making the clutch heavier than most?

I drove a '13 Manual, NOT an AWD and the clutch was light and went to the floor effortlessly. My clutch takes some effort to depress and hold that's for sure!!

However I'm going to have the alternator cable looked at just because. Car has been flawless since I got it with 18k on it and I have 43k on it now. Besides normal maintenence, I have not had to replace one part on this car unless I wanted to, i.e. Mods!

Could be the alternator cable as suggested by many (a known weak spot) or it could be the alternator itself.

Had a similar problem. Car would be very hard to restart after a short period of time being off. I thought that the heat from teh engine had increased the resistance of the alternator cable.

Brought it to my new Indy shop and they diagnosed the problem as the alternator itself (they checked the cable and it is fine). Cost for a remanufactured alternator from Boesch was $650 (an OEM one from Porsche was $1060 ) and labor was around $300.

Good luck!

I think the OP is talking about a restart immediately after he stalls the car, not after a normal turning off of the engine. If he is talking about weird noise with a restart immediately after a stall, I think it is "normal." I have had two 997.1 and my current 2012 GTS and all three have done as the OP described after a restart following an engine stall. Fortunately it has never happened but about once on each car because the engine does sound bad on that restart.

I have never had an issue with alternator or cable.

Me too have the same terrible crackling engine sound right after I stalled the car. I thought something wrong but apparently it is normal

Exactly. Only after a stall. Normal driving no problem. Guess it's just part of the cars personality.

C4S clutch should not be stiff or hard, mine is very light actually. Stop stalling, problem solved.

I've been to the dealer and they drove it and say it fine. Others have driven it and say it is stiffer than they are used to, but seems to be fine. Engages fine and is smooth. Yes, if I stop stalling problem is resolved!!

So i always had a lazy start, it used to get lazier when hot. Yesterday the car just decided to not start at all. It just lost the crank. Electronics work fine.
It is on the way to the dealer on a nice flatbed.
what is everyone's take on this?

There was a bulletin to replace the cable on 997.1.
Wire gauge was too small and would affect starting when it was hot.
New cable should solve the problem.

Guess 3: Both

There was a TSB?
So does that mean that if needed to be replaced, it would be covered?

Any links to the TSB?

Good question. Under CPO sure but otherwise, I don't know.
I would think there's a time limit but can't hurt to ask.
