I was once a member on the TDI tuning club and they said the cat hardly makes any difference to emissions on diesel engines.
Diesel particle filter on the other hand, you want that.

Does the MK 4 Astra 2.0 DTI have one of these DPF things?
What does it stand for? Diesel Particulate Filter?

yeah, stops all the little bits of soot flying out, they get clogged up normally unless you give it some bootage to clear it out, needless to say mines nice and clean
Dont know if your astra has one
