E46 318 (M43 Engine) Exhaust emission warning light..
Discussion
Started my car yesterday and the "Exhaust emission values have deteriorated" warning light stayed on. I then drove a 250 mile journey and the performance and fuel economy seemed the same as before.
The car is a 2000 E46 318 with the M43 engine and I tried to read the fault codes today. I have an OBD2 code reader but I was unable to get it to connect to the car. Would I be correct in thinking that this car is OBD and not OBD2 and hence unable to connect with the reader.
It has the 20 pin connection under the bonnet so would I be better off buying another code reader that connects to this, rather than trying the OBD port?.
I also understand that there is some trick you can do using the mile reset button to read the fault codes? Is it possible to do this rather than buying another code reader?
If I do have to buy another reader can you recommend something that will do the job?
Many thanks, this is the 4th different warning light I have had in the 3 months I have owned the car!
