Hi, I am a newbie to fault diagnosis so require a little help. I have a late 04 w203 c220cdi and the EML came on last week. I just purchased a cable and have plugged it in and I got the following back from my software:
P0426 Catalyst Temperature Sensor Range / Performance
P2084 Exhaust Gas Temperature Sensor Circuit Range / Performance
So my logic says that I should find out if the above codes come from the same sensor or two different sensors, which is where I need some help. If two different then it is not a sensor problem but could be more serious.
One observation is that when driving I notice that the drivers console side footwell gets warm and I assume that this is where the exhaust passes which may indicate that it is not a sensor problem.
Any help or next step suggestions would be much appreciated.
