2001 BMW 330Ci Q&A

2001 BMW 330Ci Question: Code reader ?

I have a service engine soon light on , so I plugged in the code readed and got a code of E3 and E4 which said o2 sensor adaption limit cyl # 1-3 4-6 Does this mean the O2 sensors off the manifolds are bad?? -
Answer 1
These codes are worthless - even just to assume anything. They are not the manufacturer's code, nor OBDII codes. I'd suggest to get a real diagnostic at a BMW specialty shop. Zee -
Comment 1
Well I replaced the 2 - o2 sensors and the light hasent been on sence, will see? -
