Maybe via OBD, but not on OBC.
Oli- Good idea by the way.
I think we should list important info like shanneba did above. There are several factors that could affect the temp reading. Such as:
-Water wetter
-Ambient air temp
-Radiator-Stock or aftermarket
-Water pump- Stock or Stewart etc.
-Pulleys- Stock or Under driven
-Electric fan- Manual
-Manual fan- Auto
-Tstat- OEM or Alum etc.
I will test mine later and post the info.

They can - all E46s have the same oil temp sensor as the e46 m3. But the cluster doesn't report it in the non-M cars. You can read it through the OBD2 port though.
I don't think oil pressure can be read
so what is the ideal operating temp for the ZHP? 95 degrees C?
WOLFN8TR: 90
Stock everything except ESC Aluminum water pump pulley. Outside air temp 84.

Thanks for the data point Woln8tr.

Thanks BTW.

Not so sure Pip is that far off the norm.
Ya, I wouldn't be at all concerned about 97 degrees PIP.
I still haven't had the opportunity to do any work - honestly I don't expect to have the chance any time soon. But I do have updated numbers to provide - checked again yesterday on a whim. It was a colder day than the first time I tested, and I wasn't driving quite as spiritedly as I was before, but my temp got up to 87°C at a stop light. As soon as I started moving again it dropped back to 85 or so, but it's still marginally better than it was last time.
98 still with coolant leak.
Mine is at 95, 65mph on highway in 6th gear is goes to 93. 2004 6MT
Ok here is something weird, since doing this my gas door will not stay shut. WTF!

Just checked mine tonight almost ran a stop sign and managed to reset my odometer but then got it figured out. It fluctuates a little but 95 most of the time
Bump
Feel like a bump.
I had some odd behavior recently. I was stuck in stop and go 5mph traffic for over and hour last weekend. Also, It was really hot outside. Randomly my temp dropped down to the low to mid 80s and stayed there until I sped up. Then when I hit stop and go again for awhile it dropped down again. I have not ever been in traffic like this before so I wonder if this is programmed behavior if some part of the engine is getting too hot? My entire cooling system is brand new (except the sensor in the lower hose. I reused that).
This is normal behavior and partly why BMW makes the needle sit in one spot from 75C-113C. The engine normally runs around 96-98C for maximum efficiency. To avoid overheating if the engine load suddenly increases, the DME can activate a heating element on the thermostat (that connector on top of it) to increase coolant flow. The FSM has a detailed explanation on the Characteristic Map Thermostat, and it's behaviors.
In the conditions you were driving it in, chances are it was either creeping past the activation threshold, or the load on the engine changed while it was at operating temperature. It takes my car a few seconds for the temp to drop, so that's probably why it seems random. When I was driving around in Palm Springs in the summer, the car would drop from 96-98C to high 80C whenever I stopped and started moving again.
If you want to watch it work, try this: Drive at a steady speed on the freeway once the temp is stable. Floor it for a few seconds in 6th and you should see the temperature drop. After some more steady cruising, it should creep back up to normal.
Yes, this is why the needle on the gauge doesn't move but the OBC shows correct temperature.
Since I've corrected my temperature gauge to show actual temp (middle is between 90-100deg C), I see this behavior often when I downshift to third and let it rip. Whenever the speeds are elevated and the RPMs go up, the temperature drops. On the track my needle will go down as far as the 1/4 mark sometimes (the line before the middle), then it'll go back up to middle once I'm at a steady speed or back in the paddock.Quote:
If you want to watch it work, try this: Drive at a steady speed on the freeway once the temp is stable. Floor it for a few seconds in 6th and you should see the temperature drop. After some more steady cruising, it should creep back up to normal.
I still don't think BMW should program it to show 75-110 in the middle. They should have just advised owners that it would fluctuate depending on load and temperature. Of course, this doesn't matter anymore since everything is electronic and there no longer are coolant temperature gauges in the new BMWs.
Finally did this.

Keeping it clean.
I FINALLY got my cooling system overhauled and the new thermostat installed. Sure enough, she's operating exactly as she should now... I'm seeing temperatures snap up to 95º within minutes and then it stays right there. I've already noticed my city MPG has gone up by a good 2MPG.
Hi Riker! Good to see you in the old temperature thread. And thanks for the bump!
