Pulled 4 different codes for my mercedes...but what does it mean?
13 Intake air temp signal
16 EGR
17 Oxygen sensor signal
29 Difference in coolant temps between CIS-E unit and EZL unit
As you can see I pulled codes 13,16,17,29
For number 13, does that mean I need to replace the air temp sensor?
For 16, does that mean replace the EGR? or is there something else I should be looking at?
For 17, bad O2 sensor? Do I just need to replace it?
For 29 which sensors do I need to replace for the coolent temp?
Thank you in advance
