Up thread, or maybe on the other MOT thread, I mentioned my 75 diesel had managed an easy pass at a measure 0.06. This was on a brand new Bosch emissions tester, using the OBD socket and a second brand new Bosch wireless unit to supply data back to the unit doing the emissions recording.
I have just dug out my previous years annual emissions test documents.
Each year the maximum allowed as marked on the documents, was 1.50. I have not checked the value on the plate. It is a 2004 CDti, with the 160 an EGR bypass fitted and cleaned out intake, replaced intercooler pipe, serviceable air filter, cleaned PVC. First column Zero Drift, Second column Opacity Mean Value
