Emissions warranty.
I’ve decided to go with a Malone Tune, I’m up here in Western Canada.
The reason I decided this route is to prolong the life of the engine etc. I’m also changing the oil every 4000-5000 kilometres, I do this myself.
I’m beginning to have less faith in this warranty, it sounds like Porsche Nth America are realizing what a total screw up has happened to our engines and TCU’s, that they’re pushing back a little. This is the assumption I get from frustrated owners on the forum.
Since the Tune my Diesel is running way smoother and the low speed bogging down that a lot of owners have experienced, is totally gone.
The TCU fix is next, hoping Malone have one available soon.
I’ve also shared my installation & photos of the Mann ProVent 200 crank case I installed about 2 months ago, a very necessary addition to help keep all the oil filled vapour from contaminating our induction cycle.

Stanadyne is probably easier to find, Opti- Lube isn't sold by traditional retailers.
I've been using Opt-lube for many years, very pleased with the results.
I use Opti-Lube Boost for it's Cetane improvement and have recently ordered there XL Lubricant which the
highest HFRR rating, even better than XPD.

looks like Amazon has the Opti-Lube Boost! for $27.48 USD a quart
Why is Cetane improvement better?
based on Opit-Lube website / chart, the XL does not have much Centane? but like you said the highest HFRR rating ? which I am assuming is good / better for lubing up the engine to keep her flowing...
I am all for diesel fuel additives (but me thinks only one at a time, no crazy chemistry experiment with fuel)

For the 2015-2016 Gen 2 CD the claims deadline is December 31, 2019 (VW strongly recommends December 1, 2019) and the fix has to be completed by April 30, 2020.
That gives me a few more months to procrastinate and hope that something happens to improve the fix. Meanwhile I started using Stanadyne because I plan to keep my CD for a long time.

I have started to do the same., 7 oz. per fill up of 100 litters (26.4 gallons)

My second use of Stanadyne was yesterday. Nothing to report yet.
I've been casual about the quantity of additive in relation to the fuel because the bottle is opaque enough to make it difficult to see how much is inside. I presume that it's important to add at least the minimum recommended ratio, is there a maximum that should be observed?

Since Cummins endorsed Power Service, I decided to give it a try.
Based on recommended "dosages", I ran ~20 oz through a tank of fuel to initially clean things out and when I refilled, went to the normal dose of ~10 oz/tank. That's based on interpolating dosages from the website.
Anecdotally, I think it's improved things. Mileage was up for that first tank. Engine response seemed a bit more... peppy. Placebo effect? Maybe. Time will tell, but since I was aware i might have that placebo effect, maybe not, too.
Next up, my Cummins Ram and see if there's any percieved impact on that beast. It's a 2003 (I'm the original owner) and has never had any treatment or real engine work done on it, so far.

FWIW, many of the driveability issues I was having with my 2013 CD "post-fix" were greatly reduced after an ATF and filter change.
The shifting is MUCH smoother, and there is less jerkiness, if any, from a stop. I have yet to reproduce the whole "rolling stop" issue, so that seems improved as well.
The improvement is really unexpected, and definitely worth doing the job - so if you have one of these vehicles and haven't changed the fluid yet, I would highly recommend it, especially if you're on the higher mileage side. I'm at 118K and I should have done this more than a year ago, at least..

I'm not saying that the fluid change "fixes" any of the issues caused by the emissions fix, and others may not get the same results that I did (as mine could have been "worse", so the relative change is more prominent) - but many of the items that have been bugging me with the driveability, have been nearly eliminated.
To be honest I'm extremely surprised... I can feel the difference after an oil change, but this was about 10x more of an improvement than that.

This might have been covered in the 100's of pages in this thread but I use to reset the ECU "driving habits" on our MBZ wagon by pressing the gas pedal three times while in the ACC position. There is a similar process for the Cayenne:1. Put the key in the ignition - do not start the engine.
2. Within 10 seconds of #1 - depress the accelerator pedal all the way to the stop
3. With pedal depressed, remove the key
4. Release the accelerator pedal
5. Put the key back in the ignition (without starting the engine) within 5 minutes of #4. This is necessary to recalibrate the accelerator and the pedal potentiometer. Touch nothing at all.
6. Start the engine without touching the accelerator pedal (only step on the brake to allow starting.)
7. Try driving and see what the result is.

Seems like something is missing here. Putting the key in the ignition does trigger some things, but it doesn't apply power to the computer(s), so I don't see how sticking a key in the slot and pressing the accelerator is going to recalibrate anything.
What's your source for this?

For older Cayenne, not certain it applies to 958+. A new procedure?
Other cars we have owned have a similar reset.
Dollarlongneck, thanks and yes you are correct, adaptation only. They say you need a PWIS to reset the later models but I've seen so many hidden menus and tricks, who knows.
