We bought our brand new 110 TDI 2x4 in May. I was on the point of considering a reputable option for a power boost to 140 bhp and had decided I would probably go down the plug in route. This is because, Bing down in Cornwall, the site sponsors on here are some distance away.

However, I have now had the dreaded letter from Skoda to say my car is one of those affected by the emissions scandal. Is there any point in my getting a plug in unit or am I best forgetting the idea until the recall has been done and possibly the tuners had time to adapt their units to the updated cars?

Ahhh, Falmouth we,remember you well......

I'm in the same position, except I HAVE the 'economy' version of the DTUK box......I'll be wanting to know if I can use IT after the fix or have to send it back for mod......a right pita.

Ryeman, just a thought, has anyone considered a Dyno run to check power output (bhp) before having a VAG ECU re-tune?

Then have another Dyno to check for power loss etc. to compare results ?? 

Just in case VAG mess up the tuning. :no:

I held off getting a remap because of the VAG emmissions debacle

but am worried that the car will lose power and gain a higher tax bracket,

NOT what I paid for! The celtic tuning box holds your present map plus

a new improved map and can be switched between.

It has already been stated officially that VED rates will NOT alter!

I was going to say hold off until the work has been done (to avoid having to go back to the mappers)  but I suppose going down the plug-in route means you just remove it and put back afterwards. Particularly as it has been said it could take up to 2 years for all affected cars to be recalled.

That's what I'm doing, but as mine is a 1.6 it will be pretty late next year before it's done.

Have I misunderstood something?  I thought the so called "cheat" software only came into play when the car was being tested and wasn't "active" during day to day running.

 

Fred

Yes Fred, you may well be right. But do we really know one way or the other?

 

I was going to go down the route of having mine Dyno run before the VAG recall, then again after.

If there is a discrepancy I would then reconsider ones options. Whatever that may be????

 

Also keep in mind the tuning box for a later date/decision, depending on the remap by Skoda.

 

Having the 1.6 Greeline I still want it to be economical without loosing power.

That's just it, when testing it's OK but normal day to day running will be pumping out lots more pollutants than the car was tested for.

As it does not affect out MOT and it's the USA that it is found to be illegal do we really need to have it done.

Could be that selling the car not corrected could be taking a hit ro value or make it unsaleable.

And that is my understanding too Fred.

How long is a piece of string?

I'd be inclined to think that technically European cars just need the cheat software removed to save face - BUT the fact they're changing injectors on European 1.6 diesels indicates they're going to try to hit the lower emissions that the cheat software indicated, otherwise why change them?

 

That's what concerns me with regard to a hit to performance since VW have stated economy (and only economy) won't be worse. Lower emissions, same economy, where is the hit going to be? If they could have met the targets with nothing else affected they'd have done so!

Good idea. That will produce factual information, not speculation.

Exactly, if a compromise somewhere wasn't required why have cheat software in the first place. Our car is just about quick enough, but a tad more power would be nice (hence starting the thread). I too have read in the media that 'economy' and 'driving characteristics' won't change after the fix. I simply don't see how the reduced emissions can be achieved without something 'giving' and the Skoda letter is noticeable for the absence of such promises!

Sorry - didn't mean for the thread to go 'off piste' and venture into forbidden territory.

Once I've had the Skoda work done I'm going to get the remap I wanted (I was going to get it done last month when the warranty ran out but then all this kicked off)...

 

Going to http://www.rk-engineering.co.uk/ in St Agnes so not a million miles from you either.

 

They really know their stuff, and have Vag-Com as well.

 

DISCLAIMER - I don't work for them, but my brother-in-law does. But he genuinely knows his stuff and I know numerous people down here in the VAG scene who rate them highly.

the son in law had the letter for his 1.6tdi rapid

 

apparently ecu code change and replacement of the injectors

 

so appears quite a comprehensive update, more than just a map

That's the worry with the 1.6. An aftermarket map is an option once the recall has been carried out but what effect will the new injectors have?

It wouldn't be "cheat" software if it was active in day to day running.

 

The original position with the 2.0 litre diesels was that it seemed that it was only a case of removing the illegal software to comply with Type Approval. But since then VW have said that the 1.6 may need the injectors replacing as well as a minimum. Which begs the question why? Was the European test cheated as well?  

 

The water has been muddied even more now by there also being a question mark over the Euro 6 engines (though again may only be US).

 

VW seem to have moved into the smoke and mirrors phase now and aren't giving out any hard facts. As far as we are concerned cars need to be retested again against the European rules to confirm (or not) that they passed without using the cheat software, if the UK and Europe governments have the stomach for it.

 

I'm conscious that this is not the "main" thread so won't say any more other than there is still a lot of waiting to be done before we get all (if ever) the facts and the proposed fixes.

That's right Fred, BUT without the 'cheat' it will demonstrate it cannot pass the formal test procedure.....in other words filthy ALL the time.

So now it will have to consume more exhaust gas to lower the combustion temp and thus pass the NOx test WITHOUT THE CHEAT DEVICE.......and remain like that 'on road' also with passable NOx levels.

Result - less power and torque

But - same economy(?) and CO

It was always a dirty powerful and economical engine which only passed the test by cheating the exams........very naughty boy!

Now everyone is going to do some sort of 'detention'........the other boys are going to deal with Mr VW 'out the back' after school.

Edited 19 October, 201510 yr by Ryeman

Basically cheat = cars pumping out more CO2 than they're supposed to.

Recall = re-map / re-work the cars to pump out less CO2.

 

Less CO2 will almost certainly mean less power - though possibly better fuel economy.

 

I'm sorely tempted NOT to take my car back. It's currently a 170. If after the "recall" it's suddenly down to 150 or similar I will NOT be happy.

 

If I was a 2nd hand buyer I'd be looking for a car that HAS NOT had the recall work done. I would pay more for one of those personally. Unless someone can categorically convince me that the rework did not cost the car BHP or Torque.

 

I think the remappers are going to have a field day!

I was going to say hold off until the work has been done (to avoid having to go back to the mappers)  but I suppose going down the plug-in route means you just remove it and put back afterwards. Particularly as it has been said it could take up to 2 years for all affected cars to be recalled.

The problem with that is the fact that the parameters will have been changed by the recall which will mean, I'd think, it would be risky without re validation of the box somehow, by the manufacturer (for me DTUK).

An alternative to the tuning box would be the Shark Performance STS system - enables one to swap between original and remap maps. What will happen once the VAG software update has been carried out, who knows but at least the map can be back to standard when it goes in.

Those of us of the 2.0L persuasion, seem to be getting a simply power robbing fix(up) but the 1.6ers will be much more interesting with regards to outcome.......I'm certainly in no rush and won't respond till I know ALL my options.

My 2.0L CANT pass the test WITHOUT the 'cheat' as it would test as powerful AND economical BUT filthy......."removing the illegal software to COMPLY" won't fly.

"...........if it was active in day to day running" it would be less powerful but clean AND as such WOULD pass the test.

It's a perfectly legitimate diversion in this period of flux as we don't know enough to be able to take any power mod options without the new parameters.....it'd be risky to jump in too soon with an existing 'box' after the 'fix'.
