exhaust emissions test

hi ..my freelander 2.0l td4 just passed mot with an emission opacity mean value of 0.12.....thats with erg bypass fitted does any one have the readings from there mot , interesting to see if its makes a big diff.
no mention that erg had been removed so clearly not a issue.

Diesels are tested for smoke only. No other readings are taken.
