hi
i recently had a diesel particle filter fitted to my 320d at my local bmw dealer in germany.
i took my papers to the tuv center where they were processed. they charged me 20 euro, gave me a new "brief" and the group 4 sticker for the windscreen.
when i got home i looked at the new brief and noticed the vehicle was still classed as a euro 3 but with type 0001 KBA nr 17041 fitted.
is this correct?
or should it also say euro 4?
