Hey Guys,
Need some help and any advice or direction would be great, I have a 2000 E46 328i and my check engine light came on with the code of P0135 ( heater to the 02 sensor blank1) I replaced it with a new one and reset the CEL and the next morning getting ready to go to work within 3 mins of starting it up the CEL came on again with the same code of P0135. I then check the connectors and wires and reset the CEL and drove it all the way to work which is a hour an 20 mins ride. and the CEL did NOT come back on.
Next morning getting up to go to work started my car up and again within 3 mins the CEL was back on with the same code of P0135, So now I replaced ALL 4 sensors with new ones both Per Cats and both Post Cats, I have check the fuse and check for voltage on the blank1 02 and it does have 12 volts with the key on.
So this is driving me crazy !! so any help or advice would be great, I really dont know what to do next I dont know if there is a relay to check.
