proton service center screw up my o2 sensor.
when there just to change the rocker cover gasket because oil has been leaking.
he simply take off the o2 sensor without checking it (or telling me) in the first place.
when he tried to put back the 02 sensor, he is struggling there, as all the wiring came out.
then he asked me, do you use the wiring?
so i told him off that was the o2 sensor, before you take it off do u check how was the wiring attached before?
he simply said 'oh i tak perasan tadi'.
he took at least 15mins - 20mins to figure out how to put back the o2 sensor, then out of sudden, he broke the clip (the clip is to hold the wiring).
then he told me my o2 sensor wiring is too short (i change my extractor 4 years back, the sensor is at the bottom, all the while no issue).
when he finally able to put the wiring (use black tape to hold it), after start the engine, 'check engine light' on.
he asked me to change to a longer o2 wiring, and he said it will cost RM 180++, and I have to pay for it.
