Ok now some of you may or may not know that I have an over-fuelling issue with my E34 520.
So today I went to see my mate and got the codes read, the scanner said that the was a problem with the O2 sensor heater relay.
So upon further investigation we discovered that there is no O2 sensor heater relay!
It should be where the arrow indicates according to the bentley manual!!
As you can see the relay isn't there and there is no wiring at all going to that position!
How can this be?
Now I can understand the code coming up if the relay was missing, but surely the car should have one!
Any help with this would be greatly appreciated as I really need to get this sorted as the smell of excess fuel is getting to me now! lol
