Any help with this would be greatly appreciated!
1996 E230 Estate (Model 210), failed MOT test because the emissions
(CO2) are too high. It has had a new catalyst fitted 2 months ago, a
new temperature sensor, so far no change to the problem. I'm about to
change the <excuse spelling> "Lamda" (Oxygen sensor in the exhaust
I've had it checked on a Mercedes diagnostic computer and the results
have so far been inconclusive.
Any suggestions as to how to reduce these emissions? It's currently
reading CO2 0.4 and I believe should be below CO2 0.33.
Thanks in advance,
