I have a 1995 MB e320 with a 104 in it. The check engine light came on (cel) and I have the blinking light impulse codes 2,3,6,10. Can anyone tell me what those codes are for and possible fixes or give me the dtc sheet list for this car and model. Also tell me if I need to get an OBD1 reader to futhur look into those codes specifically. Thanks in advance.
