Default Let's play a game (coolant related)...

How long do you suppose it would take OEM blue coolant to turn this lovely shade of olive green/grey? Was it even blue to begin with? Either way, I just flushed the system with the OEM blue stuff. I've never seen coolant this "drab" looking. Even 5 year old Prestone shouldn't look this gross...unless its even older than that (in which case the previous owner gets a big )

I just picked up my M3 not long ago (after owning an E46 323i for a decade), and had a recurring p0128 code, but thermostat and temp sensors are working properly (verified with laptop monitoring over multiple days). I sense this coolant concoction I've been rolling around with might be the culprit...and yes, I should have checked it sooner.

Hoping this fixes the issue for now. If not, back to the drawing board.

my guess is they added in some green stuff at some point - never seen that from BMW fulid - but never left it in over about 24k miles either. But it's still somewhat translucent; if it doesn't feel viscous/thick, it's probably not too bad.
Hope you put distilled water in with the new blue stuff; most important thing you can do. Its the minerals in water that cause the most corrosion/contamination.

To me it looks like it was converted to a green antifreeze at some point, then water was continually added over time which diluted it down. Then somewhere along the way it got contaminated with oil.

As far as I can tell there was no oil in the old coolant...the stuff was like water with no tackiness whatsoever. Just an odd color that (as others stated) seems to have been mixed and diluted over time.

...and yes, complete system flush/bleed with the good stuff (mixed with distilled water of course). Took the car out for a lengthy drive last night, and noticed right away that the coolant got up to proper temp faster and stayed consistent for an hour long drive. I cleared the p0128 code prior to the drive and it has not come back yet, and is not "pending" either.

So far, so good.
