O2 sensor heater...what can affect it?

Brn/Red is the INPUT to the cluster, not a VSS output. Try again.

there's no VSS "input" on C3. C3 is for the OBC only, and it's definitely a VSS output (from the cluster to the OBC). it would have been easier/simpler to just plug it into one of the spare VSS outs on the green plug block but whatever. :)

I keep hearing about this green plug on the back of the cluster, which I don't have, and everything on the back of the cluster that has a plug is plugged in.

I've got a white, yellow, and blue plug on the back.
I've got a Motometer (EDIT: VDO) cluster, maybe that's why?
Also, my cruise is deleted.

it's there, you've just not noticed it.

the VSS output on C3 is equivalent so it really doesn't matter.

my cluster doesn't have the green plug either, 318is here. i do know what you're talking about though, i bought a cluster a while back that came with it.

Mine doesn't have it either, does it somehow get the reading from the ABS sensor?

For reference, this is the back of my 325i VDO cluster
(white plug disconnected just to get a better view)
The red thing coming off the yellow C3 plug is just my tap into the BRN/RED wire for VSS (that I hope is correct).

You sure thats a motometer? Says VDO on the back...

LOL - Oh yeah, I forgot. I had a motometer and switched to the VDO. But I tried so hard to convert the original 89k mile Motometer cluster to work, but I couldn't find a 7k tach that would fit.
...Edited my previous post to say VDO.
Thanks...I feel slightly retarded now. :-P

so did you wire it up or not yet? GEEZEEEEEE! :)

yes...see post 87

[lolcantturn]

And no fix? Damn.

I didn't have my VSS connected at all (pin 14) so I connected it today, let the car run for about 5 minutes and nothing, no improvement in anything. I have continuity too. Perhaps I should have reset the DME?

I've unhooked power to the car numerous times. In fact that used to be an S.O.P. whenever I was done with the car since I've got a crappy Optima battery that likes to die if I don't keep it charged. I've since installed a battery tender.

Reset my DME for 30 seconds and let it idle......no difference. still seems like its running lean. Blah I give up.

You checked fuel pressure? It takes 20 seconds
