2016 Cayenne S diesel software recall - emissions
Discussion

Further to my car negotiations, it now appears if I buy the car I have to sign to say I understand that should further software mods be required, I have to allow them. Also if the car is 'banned' for some reason in the future,Porsche will buy back the car if this happens up to and including 4 years from purchase at various percentages based upon age.
This all says to me that further changes are likely to come along??
If anyone wants a copy of the documents just advise your email.
Based upon this I don't think I'll be moving forward on this particular purchase.
Wow. What that tells me is that they have no idea where things will end up! Also tells you how necessary it is for them to update the software, I wonder what that software change really does! This all says to me that further changes are likely to come along??

Hopefully, here is a link to the web site that I found. I have no experience of these people and have not as yet registered with them, but will probably do so in the next week or so.

I'm in Scotland so needed a firm running a class action in the Scottish courts. Found one but they say the list of claimants is closed and I can't join in! /www.caremissionslawyers.co.uk/porsche-emissions-scandal-compensation
If my understanding of the position is correct, I (and other owners not in the existing action) can rely on any precedent set and use that in our own action? Any lawyers that might read this care to comment?
Re the 8th gear thing, took mine on a run today and it changes up at around 75 and holds it on the way down with a constant throttle to around 65. Seems crazy not to use 8th at (say) a 60-65 run on A roads. Wonder what the detrimental effect on consumption will be?
Finally - anyone any experience of, or investigated, chipping as a way to restore lower speed use of 8th?

When we bought our Cayenne last September, on collection we were also provided with the 4 year buy back documents, which was a little surprising.
This week, I had a good motorway run and checked the change up to 8th gear which was consistently at around 63 mph and holds down to around 60 mph. Software update has not yet been done. I can't help but wonder if Porsche Germany overlooked the fact that UK speed limits are lower on motorways than most European countries.
Latest response from the supplying dealer as follows " I have asked Porsche Customer Assistance to contact you to give you the proper/official answer ". I will update further when I have heard from Customer Assistance.

Right, today i got to drive the car properly and i cant understand whats going on.
changes up to 8th at 54mph and will hold 8th down to 50mph.
So im not sure whats gone on elsewhere, the recall has definitely been done. The car does drive different. i.e in sport mode it changes up earlier unless your thrashing it and was noticeable the first time i used it after getting it back (i basically only drive it in sport mode).

I have now received the following response from Porsche UK
‘’We are aware the software changes do make the car feel different but it should still have the same performance as the engine torque and power remain unaffected.
The characteristics of the gearbox are changed and also the operation of the “sport” and “sport plus” modes. I am unaware of the 8th gear issue specifically, it may not select it automatically, but you can still manually select 8th gear by using the gear shift paddles.’’
Not really sure if this helps or not.

Which is a clear concession ‘the car you bought will no longer drive as it did and it only drove as it did because we fitted software to cheat the system’‘’We are aware the software changes do make the car feel different but it should still have the same performance as the engine torque and power remain unaffected.

I think some serious knocking on Porsche’s door needs to happen

Scrolling through the thread, until I read your post, I was beginning to think mine was a one off! Same here, in normal mode it changes up to 8th at 55 on a gentle throttle. Easing off it will drop to 7th c51. My next OPC appointment will be in March so I’ll watch developments with interest ahead of my inevitable software update. changes up to 8th at 54mph and will hold 8th down to 50mph.

Not really happy , had my 2013 Cayenne 4.2 V8 in at the dealers for a new replacement transfer box fitted , paid for a Major service done too why it was in and Porsche said my car needed recall work ( DME Upgrade ) , I stupidly didn't read up on this, got me car back and it drives really bad compared to what it previously driven like ( a bit lumpy and not as smooth ) , always wanted a remap so took it in yesterday
Put it on the Dyno to start with and it was running 327.8hp , 804Nm
got it to 404.8hp , 933Nm
Seems the car was 50hp down after the DME upgrade , is that right for them to do that, I understand altering the emmisions but losing 50hp isn't good and I wasn't told that

Has anyone else had this loss of power problem after having the software update ? Seems a little worrying after the assurance I was given by Porsche GB. Still delaying having the recall work carried out.
Also, be interested to hear what the general view is on joining the "group action" that is now going to be run against VW re these emissions and fitting of cheat devices

See my post above, mines been done or at least im told it has.
Does not seem any slower at all (i assure you i use it
)
it will sit in 8th at whatever speed i mentioned before.
Only difference is it seems to change up like its in comfort mode - but only if your driving normal.
i dont get all the posts with issues as mine seems totally fine. just as quick as before.

Also happy with mine, don’t see any loss of power or disadvantages. Does not seem any slower at all (i assure you i use it

If there is one thing that Ps me off though it’s the engine having power cut when braking. I left foot brake so like to play one pedal off against the other at junctions etc and the power cut seems to take an age to come on again.

I agree with her, though I do quite like the new configuration of the sport button - a combo of the updated normal mode and the old sport button. I can always switch to manual for manic mode but I rarely do (or will). Interestingly, despite the changes, it will still happily hold onto 6th at c.33mph, a fraction over 1,000 rpm.
Anyone have any views as to the impact on the DPF regeneration process? Is it likely that the engine, when previously in 8th at 60mph, say 1,400 rpm, was not running hot enough to regenerate? Maybe at 65mph+ the revs are now sufficient to do this. Either way it must surely use more fuel now.
2013 4.2 S Upgrade prior to warranty work. Wouldnt do the work without the upgrade.
Its my wifes car. Beforehand we always said it was the best we have ever owned. After the upgrade its lumpy and frankly laboured especially at about 1000rpm.
Feels like a different car and definitely down on power.
Nobody has mentioned the prospect of reversing the upgrade. There must be some clever bod out there that can do this. Food for thought chaps?

Hi, just had my 2017 cayenne S diesel serviced at Porsche dealership in Melbourne, Australia and without my consent or knowledge went ahead and did the emissions software upgrade and I am furious. The car does not perform anywhere where it did prior to this.
they now tell me they cannot reverse it.
Can anyone advise if this can be reversed .

It looks like the recall was mandatory in Europe for emissions software upgrade. Here in Australia its voluntary.
cars affected according to what I've read for both Europe and Australia are, Cayenne and Macan 3.0 litre and V6 Diesel. I cannot see that this software upgrade applies to the Cayenne S V8 twin turbo diesel. Can any owner of a Cayenne S V8 Diesel confirm this.
The Porsche dealer who upgraded the emissions software in my V8 Diesel did so without my knowledge or approval and are now trying to say that it had to be done because Porsche would not cover the cost under warranty of the transfer case. To me, this does not pass the pub test.
When the car is in sports mode or sports plus there is a change in the gearing of the car and it now has a lag or less responsive.
