Cayenne S Diesel 4.2 V8 - Mandatory Recall ref DME Reprogramming

Hi guys, never posted here before however I received a Mandatory Recall letter from Porsche GB Ltd in April stating my Cayenne S Diesel needed a software upgrade to quote, "improve the engine control system in terms of nitrogen oxide emissions". I wondered if anyone else has received this and what you make of it...........? Thanks in advance. Paul
 
Yes - I have received the same letter. I think it is not just a poor translation but has been deliberately written to be vague. I certainly won’t be having the work done without a clearer explanation of what is going on.
 
Yes I agree and with talk of software adjustment to reduce nitrogen emissions I'm thinking, is this basically Porsche saying they fitted my car with an emissions defeat/cheat device? Coincidentally (perhaps) a class action against VW Group in the High Court onb6th April received what the media describes as a 'landmark ruling' enabling claims against VW. Was Porsche's letter triggered by this ruling just 9 days earlier I wonder? After 5 years of silence this seems a significant coincidence.

I dont want my car 'reprogrammed' either, however the letter does say this is a 'mandatory recall' which leads me to think Porsche Centres won't work on my car unless I have this work done. ??


 
Hi All
I have a 2017 Cayenne 4.2 Diesel, lately it has been bringing up a warning " Diesel Particulate Filter faulty need Servicing".
I have read the manual and its states drive the car for about 10 minutes and keep revs above 2000rpm. I have done this
and the problem seemed to have cured itself until last week the warning appeared and the car went into limp mode.
Contacted Porsche and they advised not to drive the car and contact Breakdown get car recovered to Porsche Centre.
Did this and approx a day later was contacted by Porsche Centre and was advised that the DPF was at level 3 blockage
and that they had it regenerated. Car is on its way back to me as i write this. They said it was down to short journeys
but i have told them i do not do short journeys and am aware of problems with DPF. ( I'm retired but served my time as
a Motor Vehicle Technician).
I have not received a letter as of yet.
I also intend to ask Porsche what is the procedure in Regeneration of the DPF. They only had the car approx 3/4 of a day
at most.
 
Hi
Just had a discussion with my Porsche Centre and they say the recall does not apply to my Cayenne 4.2 Diesel registered Jan 2017.
The recall only applies to the V6 petrol.

The regeneration of the DPF is carried out by the Porsche Diagnostic Machine at the Porsche Centres.

My Cayenne S D 4.2 is 2015 (Euro 5) and is subject to this mandatory recall. I know for a fact this also applies to Euro 6 4.2 SD vehicles as the data regarding this is published on the German KBA website, just search 'porsche emissions' on the KBA site. Google will convert to English. I am advised by experts in the field that these recalls are to overcome illegally installed emissions defeat devices fitted at manufacture.
 
That is certainly my suspicion. I am not a lawyer but the legal situation is interesting in the sense that the vehicle no longer belongs to Porsche and if it relates to emissions (which is not safety) I don’t see how Porsche can insist that the work is done if the owner is oppose. They maybe within their rights to refuse to service the car if it isn’t done I suppose.
 
You're right there, Porsche have told me they will refuse to extend the warranty if I don't have it done. Also I'm told whenever it next comes in for service, the update will be carried out regardless of whether I want it or not.

From a perspective of logic, a 'defeat device' wouldn't have been fitted if not necessary to improve either performance or MPG, so removing the device must negatively impact on those parameters.

From what I can gather the 'mandatory' part of this 'mandatory safety recall is the German KBA forcing Porsche to carry out this recall to reduce nitrogen emissions. Anyway i have taken expert advice and can give you a point of contact if you email me. paul.1204@hotmail.co.uk
 
I haven't received any letter re mine (2017 4.2 S Diesel) but it was in for it's first MOT and 111 warranty check on 17th June - I wonder if it was updated then and hence no need to issue me with the recall?
 
Well I've checked with my POC mentioning the German KBA ruling but they have confirmed that my Apr 2017 4.2 Diesel S (Euro 6) is not affected, although they admitted they have done some software updates on some diesel Cayennes. They stated:
"Different country markets have different Emissions laws, so not always a good comparison to make in most cases. We search specifically to Vin".
So given that confirmation and the fact I've had no letter I'm assuming mine is not affected.
 
Hopefully any Cayenne SD owners who haven't received a recall letter aren't affected. However the KBA website definitely states Cayenne SDs 2013-2015 are to be recalled, and its the KBA who tells Porsche what to do, not vice versa. Re advice from OPCs, Ive asked several times since 2015 if my SD was affected and on each and every occasion was told absolutely not.

I guess only the KBA can clarify absolutely so just Google their website and use their Contact form. Any difficulties, you should be able to do a Freedom of Information request.

Unfortunately this site won't allow a standard mobile phone photo (of the KBA page) to upload.

Well as per my post late July my OPC assured me my Cayenne S 4.2 ,Registered Jan 2017 was not affected by the recall and that it was only applied to Petrol
Cayennes.
Was away for a few days and guess what Recall Letter arrived advising me to contact My OPC to get the work carried out. Really unhappy about the confusion
I have been driving my Cayenne S in sport mode most of the time after having to get the DPF regenerated as i don't want to go through the recovery action
again.
Will contact my OPC and advise all of the outcome
 
Hi, yes i anticipated you would. The KBA website states all Cayenne S Diesels are to be subject to emissions recalls, 2013-2016. The site rules restrict what can and can't be said here, but feel free to email me if you'd like more information on the true implications of this "software update" and possible recourse etc. paul.1204@hotmail.co.uk
 
Hi
My Cayenne is booked in for late October to get the Software Upgrade. Has anyone got this installed yet and if so feedback
would be great.

 
Mine had it done three weeks ago
Dont know if it is me but the strat stop now seems over eager on restart and sometimes surges forward.
Feels a bit lumpier at times and snatches at gears occasionally especially when cold - but could just be me
 
Hi
I have had my Cayenne looked at several times by my OPC with regards to gearbox unsmooth changes and it is still the same. I haven’t had the software upgrade installed yet. I have it booked in for December 4th to install new software and also to check the gearbox again.
At the weekend there the " Diesel Particulate Filter requires Servicing” came on again , really p....d off , contacted my OPC and they say get the Software Upgrade done and it may cure the problem. I really don’t think it will but let’s wait and see. I have been a Porsche customer for a long time but my patience’s is running out with regards this diesel scam.

 
Have had a voluntary software update meant to improve the 'mileage' here in Australia for my Cayenne S 4.2 Diesel V8... Would caution this use as the car now runs in all modes at close to 1000rpm This causes a decided and un-nerving "hum". I know the car has tremendous torque, but it almost sounds to be labouring...putting load on the rings etc...It was previously much sweeter at 1300+ odd revs. I have not seen better mileage of any significance either. Presently, I have resorted to Sport/ Comfort settings with Paddles... not an easy solution for an ancient driver with 7+ years of using the "Auto" since new.
Another prior problem was the jerky 'bumps' when travelling on smooth roads under acceleration; almost like driving over a fine transverse crack in the pavement. This also occurred when turning. Problem was solved by replacing the Transfer Case.. (Thankfully under extended warranty!)

 
Anybody got any further experience of the Cayenne emissions recall? I've just discovered my Apr 2017 Diesel S is now subject to this and the software update will be applied at next service. I understand it's mandatory to ensure extended warranty but wondered what effects anyone might have experienced as a result.
