Hi all. I’ve got a bmw 316 with a 323 engine, it’s a drift car bottom line. I bought the car last week so have no clue about these cars yet. The battery went flat, I charged it up all okay and it went flat again, so obviously there is a drain somewhere. I noticed that when you put your hand on the rear bench there is a whirring buzzing vibrating feeling/sound, this says to me the fuel pump is constantly running (engine off key out) which I’m guessing this is my drain.
I done a Snap in Scan just to check for any faults and it brought up o2 sensor heater problem. I cleared the codes, scanned again (before starting or anything) and o2 sensor codes won’t go away. Now I read somewhere someone with the same issue and that they are linked however he never come back to the thread. Any help?
