Differences in Diesel - Euro 3 and Euro 4 - DPF

Can anyone confirm this? I believe that the 2.0 TDCi with a Euro 3 engine does not have a DPF?

I noticed that it is a lower road tax bracket than the Euro 4, and I understood the difference was caused by the DPF being added to the Euro 4?

I have always believed that all the 2L diesel had the DPF and it was Euro III / IV for the 1.6 diesel that was the DPF fitment


I'm not sure what Euro figure that my 54 plate 2l TDCI is but it does not have a DPF



At the time when I was considering which car to buy, I saw that DPF fitted vehicles gave about 2mpg poorer fuel consumption.

Euro emission stds (including the proposed Euro VI) are across the whole of Europe and are part of Homologation so will effectively be the same for every country

The physical method by which the manuf achieves the std may be different slightly for different countries but each seperate variation will require individual approval and that didn't come cheap even 20 years ago when I was doing them so probably even less so now

For those with the earlier 2L diesels
Perhaps we can see which engine emission code letters people have just to see how many variations there actually are?

The character in question is the bottom left hand one in the VIN plate

Hello Bob. Thank you for your post. What you noticed and think is exactly what I did. I noticed a lower tax bracket and better MPG from a Euro 3 diesel. In addition I cannot find any reference to a DPF in my handbook.

I know a lot of people worry about DPFs (like they do about dual mass flywheels - rightly or wrongly), but I always understood that if you ran your diesel in a 'normal' way with variety as opposed to a lot of short or slow journeys, then your DPF should never really cause any problems, except when it wears out, if they do.

I also wondered about it all because I have read on here about references to additives running out etc. that is needed for DPFs, but I had never heard of this before coming on this forum, so it set me thinking. My own manual makes no mention of this either.

Hello Richard - thank you for your post. I will look this number up for the forum soon.
