What about calibration after an oil change? If I remember correctly, after changing the oil you should do it with PIWIS, or does it not matter?

If you can find a dealer or chain-style independent that will actually do that, get every service done there.

I hate the service advisor being between me and the tech. Especially in indy shop chains, service advisor will maybe note down half of what I say and then it’s a game of telephone till it reaches the mechanic working.

I have a small 3rd party shop that shows me the state of parts they replace, let me near the car while the work is done, let me pick what brand replacement to use (if not OEM) and never try to upsell me on anything. It’s a small mom and pop shop. Literally, the family come in a minivan in the morning and open the shop. I love that place.

Can you use iCarsoft to find the wear parameter?

I have no idea.

What's good everyone? Hope all is well. So, I've started experiencing this transfer case issue w/ my 2016 Cayenne GTS. As soon as it started, I came to the forums to look for any information. Well, i've found it here. Sad to say, my 2016 extended warranty ended this time, last year. Since the 2016 warranty was only 7 yrs, versus earlier models getting 10 yrs, mine began failing right outside of the warranty period. I contacted PCNA, via email, to ask about the warranty and see if I had any recourse. From the response that I received, it can be summed up as "you're on your own". Wow...thanks Porsche. This being my first Porsche, after a line of Range Rovers, I expected much more from PCNA. Alas, they are much like any other brand of manufacturers. And, now I'm looking at $4800+ to have it replaced. This sucks.

Based on other's experiences via this forum and other platforms, it wouldn't hurt to try to change out the TC fluids to see if there's any improvement assuming your symptoms aren't horrible. I've also read completing two fluid changes within a short frame (500 miles for example) made a big difference.
Something to consider before laying down all that cash to replace the TC.

Wondering the same about the Launch x431

I agree here to change the fluid first. Our 2016 S had the slipping, jutters feel. Local stealer wanted over $3K to change the TC and didn't even offer to change the fluid. I changed the fluid and it's all good. I plan to do it again at the next oil change.

Same issues with 04-10 Cayennes?
I've been eyeballing some 2009's for purchase.

Now, Maybe I'm running away lol

No common issues with transfer cases in 2004 to 2010 Cayennes. This problem started with the 958 transfer case.

Did you try to escalate to PCNA management? Timo Resch CEO PCNA, Joe Lawrence Executive Vice President & Chief Operating Officer, Glenn Garde
Vice President, After Sales.

The general PCNA customer service replies are a word salad.

I'm in the same situation. Only one technician works on my car, a former Mercedes master technician (confirmed by the Mercedes dealership.) He always takes me to my car, shows what needs to done and when the work is done shows what was done. Recently did the sparkplugs, and showed which were OK and which were "bleeding."

Compare this relationship to the stone wall between the technicians and customers at stealerships.

Which makes sense, though: seems straightforward that if you're out of warranty, you're out of warranty. Just par for the course for owning an older fancy modern car out of warranty. It was nice for many that Porsche did a warranty extension for some 958s. If you own something out of warranty, why is still having a warranty even an expectation?

@Nollege76, you feel slighted because your car's extended warranty offered from Porsche was only 7 years? The early 2011s had no warranty extension under this program at all: not 7 years, not 10 years, but 0 coverage.

Anyhow, you have other options than paying the dealer to replace the transfer case: buy a rebuilt case for $1500 and pay someone to install it. Or rebuild it yourself for $600 in parts. Or as mentioned countless times, change the fluid and maybe you have zero issues.

Apologies for not knowing multi-quote

You are correct. But life is not always that black and white, is it? This transfer case issue is a known weakness and Porsche keeps kicking the can down the road.

Again, you are correct. Recently I was checking out a 25k mile 2001 Rolls-Royce Silver Seraph Park Ward for $45k

Again, you are correct.
