The one for my wife's Tiguan arrived today.
Not sure I can be bothered of going to the hassle of getting it done to be honest.
I know they'll collect, but we need to be at home, and messing with a courtesy car for that period is a waste as well.
Might see if she can drop it off, then get a lift from them to go to work and then get them to collect her after work to make it easier.

Apparently there'll be absolutely no notable changes to performance and economy.
If that's the case then it makes you wonder why they bothered? 
I had my letter about 3 months ago and havent bothered. More than happy with it at the moment and arnt sure how they can reduce emissions without reducing performance.
I'm still a little confused by all of this. (My letter's been sat on the table for a couple of months now.)
If it is purely software, and no change to engine performance (power / torque / economy) then why couldn't those genii(?) engineers at VW et al come up with this solution to the emissions standards problem in the first place, rather than committing large-scale crimes (certainly in terms of some US emmissions laws)?
Is it only going to reduce NOx emmissions in the "test" conditions, or in everyday driving? By how much?
I'm very dubious about the claims of no noticable difference.

Apparently, I think its down to what the emissions should be in a certain gear, at a certain speed, at certain acceleration ish, and that the system recognised this and adjusted itself accordingly, to meet the target etc
So i guess all the software update does is remove this "point" in the range.
Happy to be proved totally incorrect though.

Nearly everybody I've seen online saying they've already had it done are claiming there's flatspots in power or a constant noticeable loss of power after the update. Mine will not be going in for it.So i guess all the software update does is remove this "point" in the range.

I'd err on the side of caution, read quite a few reports (mainly from Tiguan owners) of poor results after the update has been applied. See http://www.honestjohn.co.uk/news/volkswagen-emissi...

IMO they can't, at least not with a generic software update. Maybe with some fettling (gasflow/headwork etc.) by a specialist/expert and a custom mapping both performance and emissions can be improved? but in general if you make less emissions then you are using less fuel and making less power.
I don't own an affected car but if I did, I wouldn't be going back for any fix...
If memory serves me correctly, there is an option to say "I don't want the work carrying out, please stop contacting me and do not do it when it comes into the workshop for an unrelated matter". It stops the system flagging up an outstanding campaign whenever the vehicle details are entered at the dealer.
Might be something to look at?
It appears the software update takes a matter of a few minutes so I'm not sure exactly what has been altered, and it's not like they're going to release that info anytime soon either!

As i'm gonna sell the car i'm still going to get the work done so at least if a buyer asks I can say it's been done and the car is better than ever. Think it will just help me get as much as I can for it. Thanks for your thoughts and views. They have made me think quite deeply about getting it done, which I didn't expect

Essentially they will be 'feeding' the engine less fuel under certain (if not all) conditions, this will reduce the emissions because it will then use less fuel however it will also reduce the performance.The trick they need to pull is to get the best compromise so that you notice the better economy but not the power reduction...
Yup, fully aware of that. Was referring to the fact they don't really release any info on how they've actually done it. Seeing as an update to change the EGR parameters on some of the CAY*/CFH* engines could take a good 15-30minutes, microadjustment of injectors can take 40minutes and this emissions update takes all of about 5minutes usually, I'm skeptical of what they've actually changed.
Have their been any independent (well, as independent as can be with Yanks and European cars) been done for the real world NOx outputs since the update?
