991.1 GTS clutch gone in 11,700 miles, normal?
I have a 2016 991 GTS manual with only 11,750 miles running on first set of rear tires. Took the car into the dealership to address a phantom noise coming from the back. The dealership claimed that the noise was coming from the flywheel. As they tightened the flywheel, they found my clutch was totally worn. I said how was that even be possible:
a) I rarely race the car on the road
b) never lay rubber at complete stop
c) my commute is 5 minutes each way from/to work (no traffic jam)
d) yes, I do know how to drive manual transmission. I have another 997 Carrera running on 1st set of clutch with 80K+ miles on it
i do notice that my clutch really smells just from normal driving after I park the car. Anyone else experienced this type of excessive wear and tear on the 991.1 GTS clutch with manual transmission. The service manager was not helpful and said “this is normal wear and tear. The clutch will go fast depending on your driving habit”. If it was 50K+ miles, I will let it go. With < 12K miles, I don’t think it is normal or acceptable. They just told me speak to Porsche NA because there was nothing they could do since it was not covered by warranty.

If you've been smelling what could be the clutch friction pads overheating, your clutch may not have been fully engaging/disengaging causing it to slip, though this is a noticeable symptom, revs don't match the normal motion of the car.
If this has been going on for some time, your clutch friction plate probably needs to be replaced,the flywheel resurfaced if it has warped from the heat (not an option though it's been done). Other components may be compromised. If all this was caused by a defective part, warranty should cover it, something has caused the failure, you won't know till it's torn down.
Wear items are excluded unless defective or damaged by a defect. Good luck.

It’s not caused by your driving, although the smell you experienced should have triggered a dealer visit much sooner. Something is not right in the transmission, or in the linkage, and unless the root cause is fixed, changing the clutch plates will not help.
Also, these cars have a dual mass flywheel, which cannot be resurfaced.

"as they tightened the flywheel "
What? Never heard of that before.

If the flywheel was loose, this is a manufacturing / assembly defect. Should be covered under warranty! Flywheels are torqued and loctited so as not to ever loosen. A loose flywheel would definitely destroy a clutch!

You don't "tighten" a flywheel without dropping the transmission out of the car, at that point you are going to replace EVERYTHING because you are already in there. So this doesn't see to add up in that respect.
Do you drive with your left foot touching the clutch pedal at all? Even a slight pressure on the pedal is enough to cause some slippage.
I am on my 5th Porsche - all of them manual trans and I have never replaced a clutch in any of them, and one I drove to 225K miles.

Ahem...please ask the dealership for a printout of the diagnosis and post it here. Something isn't right. P-Car clutches are robust, even when abused, in my experience.
cheers!

My limited 2cents beside good input above about flywheel being lose.
i have tracked a manual quite a bit.
what suprised me on 991.2 manual was that the clucth disengagment is pretty high, you really have to let go of the pedal all the way and can’t have any pressure on it, you can’t really drive with your foot resting on it.
hope it works out for the positive.

I never leave my my left leg on the clutch pedal after each shift. I don’t experience any slippage during the shift..
one more note. They did not fix the phantom noise from the back. It is still there. Well, it is near the end of lease. I will return the lease and let Porsche NA to deal with it.

Would a clutch wear any faster on a 991 b/c of the 'hill hold' feature?
#13
Certainly can’t blame you for dumping the car. I had a Mazda once that went through 3 clutches in 10,000 miles, evidently due to a design flaw. (Dealer replaced it without complaining hardly at all.). When the third clutch was in, that car was history.
Porsche does build very good powertrains (usually), but the PDK-derived manual does give me some concern.

Three Wheelin'
I had this issue on a Ford Escort once, so long time ago. Story was, incorrect assembly of flywheel and clutch. Burned out clutch in 6000miles. Flywheel was blue spot from heat. Assembly replaced and no issue in that car after. If flywheel was loose and you still smell clutch when backing up, have Tech reverse the car around dealer for a bit while feathering clutch and fully engaged. Reverse is stronger than first gear so should induce more slip.
Have both you and service adv drive, and if you can smell clutch then there is something going on or SA will teach you proper technique
If you smell clutch, don’t take it home. Park car at dealer and if shop manager won’t help, call PCNA and speak with them directly. You should not smell clutch anytime unless you rest your foot on clutch pedal while driving or doing drag strip launch.
