2004 E320 drive cycle & secondary air monitor not ready
This is all new to me, as I am a Diesel guy. I really like the W211 wagon, but they are only available in gas for US.
I did some searching and reading about this, but found nothing for the 2004 (only older MY's). I don"t know if the procedure is the same for all years. I am trying to smog my car (CA), and am having a hard time. I just read that the drive cycle has to be completed with the A/C off. Could that be the reason this monitor is not complete? It is around 100 degrees here today, but I will try the cycle again (with the A/C off) if that is the thing that is preventing if from completing. The car is already warmed up, and it may take a couple hours to get back down below the desired temp (70*c?). I also read about the forward O2 sensor needing to be perfect. If this is the case, it seems like the least expensive and easiest thing to do. Thanks in advance for any help, Rich
