2713 DME OXYGEN SENSOR BEFOR CATALYTIC CONVERTER MIXED UP?

Not sure I understand your question.

Is that the code you get when running diagnostics on the car?

 

[Rana]

yes it is the fault code

 

[Ratslaaf]

?!

What you using to read this code? Did you do any work on the car prior to this error popping up?

 

[Rana]

I USED DIS PROGRAM yes they fix the cylinder head gasket after that i got many prob. that's the last new one

 

[ChrisBrand]

How well do you know your BMW?

Could even just be a pipe that they failed to connect after replacing the gasket. Or even a grounding issue with the coils, improper re-installation of parts after replacing the gasket, etc.

Seems like an air leak, or something similar.

 

[Rana]

i make them check all that parts pipe manifold and every thing while i am standing and see there work but no thing wrong they changed the pcv and pipes

Could also be that they used some type of sealant for sealing the gaskets and such which when burns I'm told can damage the 02 sensors.

 

[Rana]

i wana know is it co2 fault? so i need to change them or is there other things make it?
and the two sensors the same?

Any chance they stopped the two sensors?
