I have 01/1992 500E. I just imported from UAE. Many things need to be sorted after not professional service and reppairs.
First of all is oxygen sensor which hangs not connected near cat. In floor there is a rubber instead of connector. I can not see any wires going inside car. Also in ecu there is no error related to Oxygen sensor. There is only one about HFM sensor which is I pressume Air flow sensor - I suspected is broken coz car is starting really hard when cold.
Was every 500E equiped with cat.converters? If yes there was always oxygen sensor? I suspect that somebody just fitted cat. from newer model and Lambda is not connected now as was not from factory. That is why I don't have any faults in ecu?
Please help. Thanks
