It is written that millions of cars are affected by the emissions cheat where, over several years, Volkswagen has delivered cars that are programmed to give lower NOx values during the measurements than in traffic. None of the news channels specifically say which models are affected.
Based on the engine designation EA 189, I have searched with German replacement engine manufacturers to find exactly which cars apply. The list only includes models with replacement engines that are offered for sale and may therefore be incomplete. EA 189 covers the first generation 2.0 TDI with common rail.
Whether the scandal will eventually extend to newer cars remains to be seen.
If you own a Volkswagen, Audi or Skoda manufactured between 2008-2012 with a TDI common rail engine, there is a high probability that your car is affected.
Before you check the list, you need to find the car's specification sheet, - a sticky note that contains codes that tell about the engine, drivetrain, paint colors, interior and extras. Usually the dealer pastes it on the cover of the service booklet. Should you not find it there, I would look to see if it is loose with the car's other papers, or attached somewhere, for example on the lid of the glove box.

Affected Seat models are not included in the list. There should also be a 3-cylinder 1.2 liter TDI in the selection, but I could not find any engine code for this.
02.10.2015: Added CAYA and CAYB to the list.
02.10.2015: Read in a French online newspaper that VW France has made public own website where you can enter the chassis number and last registration date to see if the car is affected. Unfortunately, it does not work for Norwegian-registered cars.
Fine! Then we know that the 2012 Octavia RS tdi has been cheated with. Informative and fair. It will be interesting to see if VAG is satisfied with removing the cheat map or if they try to reduce NOX during normal driving to avoid extra taxes. The effect is that fees have already been paid for, so I do not want any reduction there.
Have Octavia from 2010 with CAYC engine, it is not on this list. Agree with Reidar that reducing power as a solution must be unacceptable. Something it will be if they e.g. increases EGR use.
Yes, that's it, at the bottom!
So the Audi A4 Avant 2,0 TDI 2011 model is not affected by this?
Check the engine code against the codes in the list. If the engine code is on the list here, it is probably affected. I cannot match some engine codes (e.g. the Audi code in the example from 2012-) against either ea189 or ea288.
No wonder Seat isn't on the list. According to other sources, about 700 Seats are affected.
Seat is very involved. I did not include them in the overview, as there are not that many newer Seaters in Norway. You just have to look up the engine code and see if it is included here.
Thanks for the good info. I have a 2011 Sharan. On my spec sheet it says CFF. After a bit of googling, I understand that a B is added for the 140Hk engine and thus my car is affected (CFFB)..
Hi Terje, thanks for the good info. You must be almost the only one on the web who has managed to write something sensible about which cars have the EA 189 engine. 🙂
Small question: I have an Audi A6 2010 2.0 TDI with engine code CAGB, which is therefore not on your list. But on the English wiki I find under the section 2.0 R4 16v TDI CR 81-176kW (ie the EA 189 engine) various engine codes where this code is not mentioned. But then in the list a little further down of various cars equipped with these engines, my engine and engine code are mentioned, "100 kilowatts (136 PS; 134 bhp) — CAGB(AUDI A6 C6 CR)". Does this mean that CAGB is also affected?
Forgot link to the wiki page:
https://en.wikipedia.org/wiki/List_of_Volkswagen_Group_diesel_engines
I have also not found anything linking CAGB to EA 189. Since CAGB is probably a variant of CAGA (143 HP) and belongs to emission class Euro 5, it would not surprise me if it is also affected. But one wonders what moves the Audi engineers have made in the software, then to create a more environmentally friendly engine that the 136 horse was intended to be...
My Audi A4 allroad 177 hp manufactured and delivered in 2015 is on the list!
Hey!
I have 2014 Sharan 2.0 TDI with code CFFB, see the engine code is mentioned but not the year. Maybe it doesn't matter?
I definitely think it is affected, yes.
Thank you very much for the good research Terje, I have just found out that both our cars Q3 (CFFB) and Golf (CAYB) are candidates for upgrading. Considering asking Møller for a free upgrade of the map system in the car at the same time 😀 ... A little service they can provide as a plaster on the wound 😁
Incidentally, I take this very calmly and expect that Møllergruppen will take its responsibility without us as customers being the victims!
I have a 2012 jetta.
It is a 1.6 tdi 105 hp.
The engine code is CAYC as far as I can tell. Is this also affected as the code is in the list, but belongs to Audi a1?
It is probably affected, but check the German link mentioned further down here. It works on all VWs.
It is now possible to check your own car on VAG's website in Germany, scroll down a little on this page and enter the chassis number of your car:
http://info.volkswagen.de/de/de/home.html?tab=check-own-car
My Audi A6 2.0 TDI with CAGB, which is clearly a variant of the EA 189 engine, was then confirmed to be unaffected.
Thanks for the link. I have tested a dozen Norwegian VW cars against the website - and it works well - but ONLY against VW. Now see that Audi has got its own link. I have tested that it works as expected. >>>>CLICK HERE!<< Guess there will soon be a link for Skoda owners on German Skoda sites too.
Went to the link and found my Tiguan 110 hp. 2011/2012 vs.
It has the designation CFFD, and is also not on your list.
I was hoping to get away with this nonsense, but it doesn't look like that anyway... 🙁
AUDI has published a corresponding search option to check whether you are affected by the "ChipNOxVirus". Enter the chassis number in the "Fahrgestellnumber" field at the following url:
http://www.audi.de/de/brand/de/neuwagen/layer/serviceaktion.html#layer=/de/brand/de/kundenbereich/weitere-informationen/layer/rueckrufaktionen.html
Hi, it was good of you to send that link. At Audi, I am actually informed that the car is affected. Unbelievable that the VAG group is unable to coordinate their databases better.
Had software "upgraded" on my 2013 Tiguan 140TDI DSG today.
I believe that there is worse bottom line at low revs. More characteristic diesel sound.
Generally worse throttle response.
Does anyone else have experience with the "upgrade"?
Is it possible to get old software back?
I just had the same thing done! Totally agree with you, have complained to Møller!
You should do the same!
Completely different car after this!

This comment from VG was right!
We have a fictitious cheat diesel with 100 hp, 200 nm torque and 75 mg NOX emissions. This 200 nm is available from 1500-3000 rpm.
Now we adjust the software so that the car still has 100 hp, 200 nm of torque, but we still reduce NOX emissions to 50 mg/km.
How do we make it happen? Well it's very simple. We make these 200 nm available from 2500-3500 rpm. The car now drives with reduced traction in exactly the area that applies to daily use. The turbo performs less and emissions go down.
Nevertheless, the customer still has a 100 hp and 200 nm, the turbo works less and emissions and consumption go down. Everyone is satisfied.
Or not? To get away at the same speed, you must now increase the revs. More noise, even more consumption and even more emissions are a fact.
Well done I say 🙂 exciting whether what I write is truth or speculation, time will tell
Unfortunately, I think what you write is closer to the truth than one could hope. If the engine characteristics change so drastically, there is a risk that the ratio on the gears will no longer harmonize with where and how the engine delivers the power. After all, turbodiesel engines are very dependent on having gearboxes that enable you to utilize the relatively narrow rev ranges. Then we not only get more noise, consumption and emissions - but also less driving pleasure. This is worrying.
Yes, I'm really disappointed today! Had a major service at Møller today for 11k and EA189 happened to be ready for the Tiguan, so almost had to take it in one fell swoop. The more I have driven today, the experience is that I lack the spray and the response. Also hears that there is not the same turbocharged sound in the lower register. This is not going to accept…
My audi b8 also has to come in this winter... Did you get to talk to Møller about the engine effect? And what did they say?
189motor.no
Here you can check whether your car is affected
How did these stories end, everyone bows and must surrender? Today my audi 2015 allroad m 320 tax-expensive diesel horses ea 189 was adjusted. The torque was gone and only responds to a flat pedal and has to howl at high revs to get thrust. The car was destroyed.
No car press writes about this problem. Many have experienced the same thing. We ourselves experienced having our Q3 2.0 177 hp "fixed" at a regular service without being told about it. The car was destroyed in the same way as you describe. We ended up replacing it shortly after. The problem is that you cannot oppose factory-imposed upgrades because guarantees. Guess there should be a market for reset diesel fixed cars. Maybe chip tuning experts have a solution?
