Hi Guys .

does anyone know what spec the CO % , is for m40 engine please.
1.6 but the 1.8 probably the same . can,t seem to find on wiki .
I know what it should be at 3,000 rpm 0.2 -> 1.2. / 0.7 +/- 0.5

thanks

Just had my 316I through the Nct (Mot) and the CO reading was 0.13 vol% which is a pass as above 3.5% is a failure. Its low idle so would assume 750 Rpm. Not answering the question as such.
