If you go on the seat website and type in your reg number it will tell you whether your vehicle is affected. My 184 fr isn't so clearly it isn't going to affect all mk3 diesels.
Interesting today , hearing that it could now affect petrol models. Wonder how all the petrol owners who were feeling smug for not buying a diesel feel now lol!
To be honest I couldn't care about it. My car runs fine and I don't care what the emission rating is.
The check on the seat website doesn't include the new C02 problems, it's just checking the N0x issue isn't it?
