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.

Looks like you and Hochspannung are on the low side (for 3 L engine running mostly stock).

Thanks BTW.

Now we need ritmusik2K and telijah to report updates.

More people answer this, moar data...

I agree :( Stock everything, but I'm thinking of doing a drain/fill of the coolant since it most likely hasn't been done in a long while. Think it'll help??
