Funny you should ask this. I am in the same boat. Seems that most of the flywheels this shop has seen have been out of spec per the Porsche tests and they usually end up replacing them while they are in there.
I asked if I could come take a look at it once they get it out just to see for myself. It's not that I don't trust the shop but it is my first time using them and I don't have anything to go on.
Keeping my fingers crossed that mine looks good but I guess we'll see.

I just did a clutch job in March at 60k. My flywheel was fine after cleaning. I would plan on keeping your car in the shop for more than 1 day. Rent a car or whatever you need to do. Once the car is apart, have the flywheel inspected and make the decision then.

I would replace it anyway. At that mileage it cannot be really good even if it looks OK. The expense of getting there is already paid for and having a new clutch together with a new flywheel will assure a smooth operation for a long time.
Besides, it is not that expensive. I think it was 700 at Suncoast when I was doing my clutch last year.

I think it would be a good idea to change it.
The problem isn't with how the surface looks. It is with how far you can turn the halves how much spring tension there is and and if they return to to the start position.
I replaced the RMS on my 2003 @ 32k mi. The flywheel was a little loose but within spec then. I am amassing the parts to do LN IMSB, clutch pack, flywheel, AOS this winter @ ~ 50k mi.
the only way to be sure is to check it when you have it out.
Porsche TSB 1360 8/02 assessment of DMF…
The twist below must be carried out by hand and without any tools. Twist distance to be measured at the external diameter of the DMF
Can the DMF be twisted by approx.. 15mm to both left and right, and does it then return to approx. its initial position? If yes = good
Can DMF be twisted beyond 15mm (excessive turn) without a noticeable increase in the spring force? Yes = bad, no = good

In theory a flywheel should last much longer than 56K. Unless the disk has been worn down so much it damages or burns the flywheel. That being said it does seem that the dual mass flywheels seem to have more problems and a shorter life than single mass flywheels.
I count myself among the lucky. I found a brand new OEM Dual Mass Flywheel in 2005 on eBay for $67, still in the box. I was the only one that bid and got it shipped at that price. It sat under my desk for 2+ years. But when my clutch started slipping at about 46,000 miles my indy said I need a new flywheel so I saved some big bucks.

Well someone else drove my car from 28k miles and I have no idea how they treated the car. I'm curious how one could cause the pressure plate to break with driving style, dumping the clutch or something stupid? I do push it hard sometimes but never abuse it. Most definitely never dump the clutch trying to burnout since I'm in a 4S.
Has about 33k on it now when the clutch went.
Hoping to get a look at the flywheel today.

well. I didnt change mine at 106K. The car now has 140K.
I just cleaned mine up very well. I will tell you that, under the "man to man" advice and thoughts of a very exp engine builder, I was told off the record "clean the bitch up and run it."
I think you are OK to run the one you have,
I cleaned mine up with a gray sanding scrubby pad
