300E a couple 1994 w124wagon E320 Wagon/,1971MGB Track/Rally, MG Midget Autocross ,2000 E320 wagon.
O2's are not fused.
that code means the heater circuit on the pre cat passenger side O2 is dead.
Fix it for the a/f ratio is now constant rich and misfires will occur and long time neglect to replace can shortly damage the cat

Threw a P0135 today. Both O2 sensors replaced a year or so ago. I don't think I have any oil leaks but need to look more closely. Can someone enlighten me on the recall sammydragon3 is referring to?
