Hi Pete,

"no-one apart from the parties concerned will be none the wiser."

Double negative? meaning everyone will be wiser?

Seriously though, the point was it may be illegal to modify the manufacturers map as this will change the original intended emissions, surely? Just because it is not detectable it does not make it right!!!

"As has been mentioned earlier in this thread, the DPF system as it stands is not fit for purpose and the ordinary motorist is being penalised accordingly."

I totally agree. I believe DPFs are a poor solution to a problem. I reckon the problems being experienced with DPFs with all the extra miles and fuel used to regen them are probably doing more harm than good to the environment overall.

Regards,

Mike
