List of common FAQ/fixes/issues etc.

I was sitting in the garage yesterday and had a curious thought process. Being of a mechanical/environmental engineering background I was thinking about part life cycles, i.e., we often measure our cars and determine what needs to be done using mileage. But there are other factors - for instance: my Durametric software will tell me how many hours the engine has run which is just as important as how many miles the car has gone. As far as life cycles, any mechanical component has a finite life cycle, such as an ignition switch. I pulled out the calculator and figured on a guess that if I use the ignition switch 4 times a day, 312 days per year (6 days a week), for 15 years (I have a daily driver 99 C2), then it has cycled 18,720 times. How many cycles does it take to kill an ignition switch?
I was wondering if it would be a good idea in the list to begin to amass some history for our older cars to determine when some components are replaced based upon hours of engine running vs. mileage (like for an AOS or MAF replacement), and estimates of life cycle usage, i.e., my ignition switch example, or a window regulator, or a starter. As our cars age like mine, 15 years, I think component life cycle becomes as critical a factor as mileage. Mileage can apply for most of the running gear components (brakes, tires, suspension, etc.) but most of the other stuff we replace/fix has more to do with how many times it has been cycled.
For instance - I had to replace the starter at about 12 years old. Based upon my example above (4 starts per day, 312 days per year for 12 years), that would have been about 14,976 starter cycles. Mine is a daily driver. Then we can surmise that regardless of mileage, one can expect about 15,000 starting life cycles before the starter needs replacement.
As our cars age and we replace common parts/fixes/issues that we all have posted about, does it make sense to include this factor? I think it does.

Ignition switch failures are largely induced by if you have a heavy keychain which makes it prematurely wear out. Case in point, PO and I both only had the Porsche key on a keychain and I'm on the original ignition switch, over 13 years and 125k miles. It has very little to do with mileage/age and usage but rather how it was used.

Since this is sort of a "HELP I got this and that" thread I was wondering maybe someone could give me an answer or maybe there is a DIY thread on this
if I want to go from this:
to this:
concerning the CUPHOLDERS
what parts do I need? is it enough with the sliding cupholders and corresponding air vents or there is something more to it? (in my car I have no cupholders at all)
since I really dig the facelift cupholders I want to install them, and since I couldn't find any DIY thread nor here nor in google, I could then post a thread myself of installing them
also while at it:
if I want to upgrade to oem facelift satnav, what is recquired? is it enough with the screen/buttons (yeah I know it is probably crappy but I really am the OEM equipment fan) In my case there is this satnav installed:
thanks

It wouldn't let me edit my original post so I just put it here. Maybe we should make this a google shared document so anyone interested can contribute/edit?

LOL, I think all topics are welcome as long as there are interests. I also want this to be a collaboration so people can suggest new contents/links and get involved.
BTW, I think adding quality links will be the starting point. If people want to write about a specific topic, that can be added to the list as well.

You're welcome! I think it would be nice if we can turn this into a Google document or something similar that anyone can contribute and add useful content. I can no longer edit the post but new things keep popping up that are worth adding.

OK. So this ought to be interesting if it works. I took the first page of this thread and put it in a Google doc which can be found here: https://docs.google.com/document/d/1...it?usp=sharing
Anyone (in the world) should be able to view the doc. I also gave permissions to Ahsai to modify the doc.
This way we can have a running list of good threads related to fixes etc.

When installing new mufflers with your existing exhaust tips, or installing new tips on your old mufflers, you may find that the clamps that hold the tips to the mufflers are rusted to the point that you need to cut them off.
Pro tip: Cut the bolt, not the clamp - it turns out that the OEM clamps work MUCH better than the knock-off clamps that some of the parts sites sell. I messed with the non-Porsche clamps I bought from Pelican for 90 minutes and never got the tips properly attached to my new Fister mufflers. When I gave up and used the new nuts and bolts with the original clamps, I got both tips installed - with the Fisters already on the car - in about 20 minutes.
I don't know why the new clamps sucked so much - they appear identical to the Porsche clamps - but I highly endorse buying a new set of "genuine" clamps if you find yourself in need of this item. It's worth the extra 10 bucks.
