100K Miles!

The error codes were for Oxygen sensors and have replaced both of them (Bought from Amazon & Rockauto). But the codes keep coming back even after erasing with the code reader. Any thoughts?

There are 2 pre-cat, and 2 post-cat oxygen sensors. By two, which sensors do you mean?

Also, what brand were the oxygen sensors?

As mentioned above, it will be helpful to know which codes you are receiving

Oxygen sensor codes are often (>90%) caused by hose leaks or other issues not related to the sensors directly.

If you got P0171/4 this is rarely an O2 sensor issue

I didn't note down the codes, as the associate at the advance auto parts was flying thru the codes and explaining the codes to me! (I should have asked)

The main problem now is the vehicle overheats and shuts down in 5 mins of driving and can't take to the autoshop (Unless I tow the vehicle or I will buy a code reader)

Sounds like a water pump failure.

An autozone code reader won't pick that up. Need to get a BMW specific one (C310) or get it to a shop.

^second that. Unless the fan was never plugged back in when the O2 sensors were installed.

I've ordered the water pump and thermostat. First will change them and then hopefully I can get to the error codes. Thank you all for your inputs
