I think people are jumping to conclusions a lot on this, not helped by lack of info from VW, hoping it'll gradually blow over I'm sure!

The defeat software does not affect how the cars drive. It only activates under test conditions, all our cars drive as they should.

The problem will ONLY affect us if our cars are detuned to the level of emissions the defeat software was designed to meet with no physical alterations, since this is for the US market it remains to be seen how it may or may not affect us in Europe. The "update" will likely just remove the cheat software and since all our cars are already in the market that'll probably be that.

Until VW tell us what the "fix" involves we just won't know, if indeed it is designed to bring all our cars down to the emissions levels tested in the US we'll all be shafted with performance definitely taking a hit, no way around the physics, look at all the 70's 5.0 V8's in the states pumping out 120bhp due to being strangled...

Ofcourse people are because they don't know whats happening... as I said see what happens... If people are not losing out no issue but if they are, they are more than in there right to kick off

Absolutely, I was more referring to people wondering if their current performance is affected, it won't be.

If our car performance is altered by the "fix" then we are quite rightly entitled to compensation from VW. It'll be a tricky one for them to get around and as to how any compensation might be worked out I have no idea! Especially for 2nd hand owners etc, so many variables...

My problem is that my new car arrives in about 6 weeks and it might affect selling of my Exeo if this hasn't all been made very clear by VW. Values are bound to start taking a hit.

How can you be so sure? Do you know something we dont?

Because it's been made very clear how the cheat software works. When the car "thinks" it's being tested due to various factors like rear wheels remaining stationary while front ones turning it activates to lower the emissions. When it's not active the car runs normally. That's the whole point of all this fuss, as far as I'm aware none of us will be using our cars under anything the software deems to be "test conditions".

Surely that's the point though. Will Seat not bring the car to always be in test mode with this fix? If that is done we will not have the same output as we currently have.

I think that's the assumption many people are making but those emissions regs are only for the US, the "standard" running of the affected engines is expected to be fine for European testing where Nox emissions aren't important but CO² emissions are.

This is why VW need to give more information out, people are jumping to conclusions and it's going to harm the VW group more and more the longer it goes on until they let us all know what's happening.

I would assume that the fix would certainly involve changing the operating parameters so that the car will run at an acceptable level to pass the nox tests. Fingers crossed this doesn't affect the power figures of the engine too much, or at least not as much as it may affect the engines in the US.

My car is also affected, 2011 143 Sport Tech ST.

Think we missing the main point here, i tried to trade in my Seat Exeo to get a BMW, from two dealers, and they wouldn't take it in, as its affected they couldn't guarantee that they could sell it on, therefore in my eyes the car is worthless until its fixed........If the rumours are true there is an american paper who has been told of the costs, i can't find it again but around 2500 per car for parts, then labour..... 2.0tdi engines and above... how true this is i don't know...

All i know now is we have cars that are worthless.....until fixed

My 60 reg 143 ST is affected by having the EA189 engine.

Not sure exactly how the defeat routine (it's not a device as it's part of the ECU firmware) works, but likely underfuel when rear wheels are stationary to lean up the mixture.

ECUs are simply pulling in data from sensors - wheel speed, engine load, throttle position, manifold vacuum, fuel temperature, pressure etc. etc. and enables each injector to fire for x duration and pressure at z time, so putting in the logic of an anomaly (rear wheels stationary) and underfueling would not be that hard to do...

I have a bluefin map on my Exeo (very pleased with it) and have the option to remove it via the handset.

The question I do have, I guess for bluefin, is will the map still apply or will I have to buy a new one?

I.e take the bluefin map off, reverting to standard, then try and re-apply the bluefin, but the map removed will no longer be the same so might trigger a checksum error and not re-apply the map - dang.

I feel a mail to Bluefin customer services coming on.

Same question and I too have written to Bluefin (Superchips) - let me know if you get a reply as I will to you.

I'm in Jimrod's camp here, it won't affect performance or fuel consumption at all, as the offending code does not kick in during normal usage. Plus let us not forget that the NOx emissions in this country are nowhere near as stringent as they are in the US. Therefore WHY in God's name would they detune OUR cars in order to meet a level of NOx emission only required in the US. that doesn't make any sense whatsoever.

Our RFD levels are Carbon Emission based, not Nox, so that will be unaffected.

To be perfectly frank, why they would spend an absolute fortune 'removing' the offending lines from our ECU's in the first place is beyond me. However if they are forced to do so, they will have to do so.

This does though leave us with the problem of falling second hand values, and this will be a perceived issue for many an unscrupulous dealer for years to come I fear, and is a REAL issue for us all.

The headlines are selling newspapers and driving wild speculation, theory and counter theory, and until VW actually come out and make a clear unequivocal statement as to what/where/when/how, etc, we will remain in the dark.

So for some, this is a great opportunity to do a little German bashing, (after all, they did bomb our chippy), and for others, it is an issue that MANY other car manufacturers have faced in fairly recent times, and managed to put behind them, including Ford, GM and others.After paying huge fines of course!!

So in closing, l can only hope that this will not fuel, (pun intended) the fire any further than it already has been.

The camp thats telling us we won't see a performance hit but don't actually know anything reguarding as to how they are going to put the cars right?

............

The main issue for me is resell value I was hoping to get rid of the car soon but if the resell value takes some sort of hit because of this don't really want to pay the car off.

I didn't realise the code wasn't activated during the emissions testing on our European cars. If that's the case then I agree with you both - there should be no performance impact.

I had in my head that the device activated during testing regardless of country so even if it wasn't required in the EU to hit certain Nox readings it still passed on that criteria, so without the device it produced a different set of results which may mean it fails the EU test.

Hi guys,

quick response from Bluefin, they seem to be in the dark as anyone else, but seem to confirm that the handset will work, but interestingly no word on whether any re-write would be required to the map (doubt it, nothing in the engine has changed unless they re-do pump and injectors etc.) or if there'd be a fee for this..

From Bluefin:

"Thanks for getting in touch.



At the moment there's a lot of rumour about what VAG are going to do and not a lot of fact I'm afraid, so we're as in the dark as you. Certainly, the Bluefin is designed to detect an update on your ECU and if detected will re-read the new software, which we can then modify as before, so you're not going to break anything by trying to re-use the handheld.



Once we know exactly what is going to happen, we will be able to advise our customers what the procedure will be, but until we know what's going to happen we can't know for sure what action we'll take."

So, a waiting game.

My car is going in for a remap on friday from Bsr Sweden
My concern is that the bsr-map want work after a map upgrade from the manufacturer.
Personally I dont want the manufacturer upgrade, but in a article it claimed you can be forced to do the upgrade.
Here's the info from Bsr:

Lately there has been a lot of attention in media regarding VAG´s emission tests and many cars are now called back. If you are affected by this and have optimized your car with PPC or have a valid Trim Warranty you can be absolutely calm. BSR´s software is always based on the latest release from the manufacturer that has been installed to your car. The manufacturers update remain and you do not lose any changes. You are not able recieve an old version of the software to your car by using the BSR system and it does not effect the emission.

I'm now confused. Entered my VIN number on the Seat website and got a reassuring message to say that my car wasn't affected however I've just had a letter from Seat to say that it will need "Service Action" to correct the problem.

Anybody else had contradictory information like this.
