E39 lambda / oxygen sensors

[Tristan]

Hmm
I must plug in again. And check out the readings. I don't mind buying 4 sensors, but don't want to throw them at it for the sake of it. The only fault / dtc was O2 sensor after cat, bank 1, voltage monitoring.

But if it was to drive better I'd get them. It seems to have a fair old smell of fumes on startup, but I still get 22 mpg cruising.

I get close to 30 on a gentle cruise

Is that after zeroing the counter once you're cruising?

Seems very cheap.

I fitted 2 of those, genuine Bosch and worked perfectly.

ecuworx do software for turning off 2nd set of sensors for the e46. I think it works for the e39 too, mostly done when removing the cats.

Its like £20 for the licence and you can make other changes too.

Have you noticed any difference? I've just bought two pre cat ones for my M3 as it's on 106k miles

That's a great little program. I used it to change a good few things. It does work for the e39 as well alright.

So if the post cat sensors were throwing up errors could you just deactivate them? Even if you weren't removing the cats?
