Dunno. Neither of those is within the scope of an annual MOT. What is a reregistration anyway?

^ export followed by re import?

I recall Ed China (?) having to get a CO2 compliant dual fuel conversion on an old Rangie I think it was.

In UK it's just CO, HC and lambda that you can fail MOT on (petrol engines, and I guess dual-fuel, tho I'm not sure which fuel they test on?). For diesels it's  just smoke AFAIK.

Of course - CO!

Causes a lot of confusion. A lot of people are worrying unnecessarily about CO₂ in respect to MOT in this 'scandal scenario'.

To me, CO2 and fuel economy are intertwined but just a different language.

Absolutely, owners should definitely be collecting (lots of) data now (brim-to-brim trip miles vs litres) before having any changes done, if they want to convincingly demonstrate a change for the worse post-fix.

I recon VW will ignore EU complaints and threats of legal action from owners .

As far as they are concerned, the U.S. is where the 'big hurt' will be.......unless EU govt's grow b..ls......what chance?.

Generally speaking yes, particularly as the UK government etc. are being very laid back about it.

They won't be able to just ignore the big, combined actions though.

Even better would be an example tested under strictly controlled on the road conditions by a respected organisation before and after the software update.

Owners data would just be dismissed by VWG's "experts".

I think the history of massive U.S. class action outcomes and seriously big govt agency penalties will make the rest small beer in comparison and there don't seem to be any serious EU threats with German investor interests taking priority.

CO2 is used in the UK to fix the level of VED (road tax)

next year only the initial purchaser of a car is penalised for it being a polluting heap of rubbish, as basically year 2 on all pay the same unless the car is worth over £40k

so much for the green creds of this government, put revenue over the environment

As with the new pension looks like another government con.

They talk of it being unfair that owners of older cars pay more than new ones but that is exactly what I will be doing! Tax on my older car is more than £140.00!

Why have you posted that in this thread?

Guys , There is no need to buy the original VCDS for 250 GBP for your yeti...There are other third party vendors  having much more reliability and functions for less than USD 90/-  Please do not waste your hard earned  money....

 

Please stop spamming multiple threads with the same info.

 

Yes you can buy hacked copies of VCDS (which have been reported to do damage to some cars).

Yes there are cheaper ways to change some codes on a VAG car.

 

I am however not aware of any (non hacked) software that will do more than VCDS for £45!

USA go off the NOx content. The uk go off CO2 so VW say we will not get compensation as its the NOx content that is the problem

That's not it at all. The whole issue is NOx. The defeat device is (allegedly) set up to run the engine in a clean mode when under test, then revert to a dirtier (but more driveable) mode when on the road. NOx levels are built in to most national emissions legislation (where they exist) including in the USA and in the EURO regulations.

The main difference across the pond is that they are set up for litigation better/differently to us, so are at liberty to sue. There's nothing stopping it happening here, it just won't happen easily or without action.

I would love to know how they have come up with a map that can fix the NOx without affecting economy or power. If so, why did they not do this to start with?

I suspect that they will be comparing peak power or torque figures. I am interested to see a full torque curve comparison before anybody connects anything to my car.

Isn't the update to remove the cheat used for testing? If so, then logically its removal shouldn't impact on the real world emissions and performance.

As said elsewhere many of VWG's cars are amongst the best as regards emissions on the road so there isn't any requirement for them to improve those as poorer performing manufacturers aren't required to do so.

But thinking about it some more I guess that in having to pass the test without the software it will affect the on road performance.

^ To explain by analogy.

VW put a smart kid in for the school exam that their own kid should have sat. The smart kid passed the test, but was later found out to be an imposter.

Now the 'not so smart' kid needs to pass the test, and his identity will be strictly scrutinised. What happens to the smart kid isn't relevant now, you can 'unprogram' him from the situation all you like, but it doesn't help the VW kid who actually has to pass the test now without help.

Nice one!

The bottom line is on-road, the erg valve will have to be as active as it was (only) in the test cell.......much more work = shorter efficient life expectancy.

Beats me why the EGR valve has to be buried in such an inaccessible position.......it's a 'maintenance' item.

Using software they can adjust the EGR settings, the fuelling (injection timing and amount) and probably turbo actuation. They will have to do this to get the NOx down, which means getting cooler combustion temperatures. Cooler combustion leads to more particulates (PM), which will be caught in the DPF, which may then need more regens, or could block sooner. Cooler combustion also leads to reduced fuel efficiency. And yes, the EGR valve may get more action and thus increased failure rates.

Not to mention the shape of the torque curve will change. Even if the peak is the same as before, the driveability will be different. It has to be.

VW are in a bind, having made assurances that they are now going to have to keep or suffer the consequences.

Our car has not yet been recalled but will apparently have the 'fix' at next service in October. My concern is if I refuse, will MOT testing require confirmation of the 'fix' having been carried out? My other concern is indeed if the 'fix' results in cooler temperature and shortened life of dpf or egr.

I was thinking of buying another diesel Yeti but now I'm not so sure if my concerns will still affect a new one.

Can't see that happening TBH. For a couple of reasons:

 

1. When would that become a requirement? Timescale for the fixes keeps moving, so how can the rules say "from this date, all VAG-group cars in the affected 'bunch' must have proof of fix having been done"? Seems like we could be waiting years before all affected vehicles have been called back in.

 

2. It would require a change in legislation, wouldn't it? A special add-on bit of the test to say VAG NO_x fix done - Y/N.

IT won't affect the MOT. Mine has passed the MOT with the cheating software in place; if nothing changes (ie I don't have the update done) then nothing changes (ie it keeps passing the MOT). The MOT check for emissions is pretty loose compared to EURO emissions requirements.
