Cayenne S Diesel recall - can I decline?
Discussion
Hi all - fairly new to the forum and still finding my way, so apologies if not following etiquette. I've posted similar to the below in another thread, but at the end of it and which has what I think is an unrelated title so I think is a bit lost. Hope it's ok to start a new thread with appropriate subject.
I've received a recall letter from Porsche for my Cayenne S 4.2d. Whilst the letter is vague, it does sound like it has the potential to change driving style (basically sounds like it wall automatically flip out of Sport mode) and performance (although it does appear to say that isn't the case)...
I've had my Cayenne for 3 months, bought privately and was booked in for its first OPC service, plus 111-point check so I could get Porsche warranty in first week of lockdown - so subsequently has been postponed.
It's my first Porsche, and I have no experience of dealing with OPCs, so would really appreciate any advice. Can I refuse the update? If so, will it fail the 111 point check and therefore not let me take extended warranty?
Be very interested to know how to refuse this but remain in the OPC ecosystem if possible - also conscious of resale value. Love my V8 S and loathe to do anything that might affect performance or even engine note.
Given lockdown I understand nobody is likely to have it done yet, but if anybody has any insight or thoughts I'd appreciate it!

The recall letter is a bit confusing as it appears to be a translation, presumably from the original German one.
My take on it is that in sport and sport-plus driving mode the engine map causes nitrogen oxide emissions to exceed Euro 5 limits. To remedy this they want to change the software in the ecu so that it does not hold the low gears and changes up quicker to reduce the revs. Apparently this will only happen if the vehicle is being driven normally but if the ecu detects it is being driven in a 'sporty' manner it will still hold the lower gears.
At the moment when I engage sport-plus in manual mode it holds each gear to max revs until I make the change and in auto mode it also holds each gear to max revs before it changes up. It also changes down and matches the revs perfectly under braking to give the maximum acceleration out of a bend. I generally only use sport-plus for very 'sporty' driving but if I am using it I want it to stay in that mode and behave consistently, not jump around the gears depending on what kind of driving it thinks I might be engaged in.
I like everything about the sound and the performance of my V8 diesel and don't want to make any changes that could adversely affect that. The letter states it is a 'mandatory safety recall' but presumably it is to protect Porsche from the legal position VW is in regarding emissions. I think I will wait and see what other owners have to say about any differences they notice in their vehicle after the update.

I checked the information once back at work - your car is not an EU6 adblue equipped car (the one the engine note is more muted on).
Officially the following applies:
ALA1 Recall campaign / workshop campaign - Re-programming DME control unit
Overview
For the affected Cayenne S Diesel vehicles with 4.2-litre V8 diesel engine (exhaust emission standard Euro 5), the data version of the engine control unit must be updated in order to improve the engine control system in terms of nitrogen oxide emissions.
The suitability and effectiveness of the software update developed for this purpose has been checked and has been approved by the German Federal Road Traffic Authority (KBA). The time schedule for the upgrade has been coordinated with the KBA.
The manufacturer's specifications for fuel consumption and CO2 emissions (combined) still apply. Compliance with the emission limit values of the Euro 5 emission standard is guaranteed. The validity of the originally measured engine power and maximum torque also remains unchanged with the new software. This was also confirmed by the technical service and was an important prerequisite for approval by the KBA.
